QUICKSTART GUIDE

Step-by-step

Congratulations on getting a Decent Espresso machine!

We hope you enjoy the art of espresso as much as we do.

This guide will help you get started.

Introduction

PART 1

Unpacking the suitcase

For reference, see our unboxing video on YouTube.

1. Open the carton from the top, turn it upside down, and

slide the box upwards so the suitcase is standing on its

wheels.

2. Lie the suitcase down on its side and unzip it. Open it

and remove the packing foam.

3. Lift the espresso machine from the suitcase and put it

on a flat surface. The best way to do this is hold the

group head with one hand and hold a leg with the

other hand.

4. Remove the tablet and accessories from the suitcase.

5. Save the shipping carton in case you need it later.

Unpacking the suitcase

Open the box upside down, so that the suitcase

wheels come out first.

Filling the water tank

1. Remove the magnetic back panel (if you have a DE1XL)

and remove the rubber band that holds the water

tubing in place. (This was only needed for shipping your

machine.) Then replace the back panel again.

2. Lift the lever in the back of the machine to slide the

water tank forward. Then fill the tray with two liters of

filtered water. We recommend using water with a low-

calcium content.

3. Slide the water tank back into place under the machine.

As you slide the tray back, remember to lift the lever

again.

See our instructions for the water refill kit if you’re going

to automatically refill water into your espresso machine.

Setting up — water

Use the lever in the back to insert or remove the water tray.

Slide the water tray forward to fill it with water (2 liters).

If you use a water refill kit

These instructions apply only if you put water into your

machine with a water refill kit. If you refill the water tank

manually, see "Filling the water tank."

The Decent water refill kit comes with a different drip tray

and an electrical box that we call the "Decent Catering

Kit." The drip tray has a hole in the bottom with a small

tube. This will connect to a longer tube, which will carry

away the waste water.

NOTE: The drip tray that comes with a manual-refill

Decent machine does NOT have a hole at the bottom.

The white tubes that come in the water refill kit will pump

clean water into the water tray of the Decent Espresso

machine.

Setting up — water refill

The Decent Catering Kit

Set up the drip tray (for waste water)

1. Insert the shorter, silicone black tube in the bottom of

the drip tray through the drain hole under the Decent

Espresso machine.

2. Connect the longer black tube to the open end of the

silicone tube.

3. Route the other end of the long black tube into a waste

bin. This can be a large container that sits on a shelf

underneath your espresso machine.

Setting up — water refill

A tube comes out of the bottom of this drip tray.

Waste water drains from the drip tray through a black tube to

a bottle for disposal.

Set up the Decent Catering Kit

1. Place the Decent Catering Kit on the counter. This

electrical box will pump filtered water from a container

into your espresso machine.

2. Take the larger white tube and connect it from the back

of the Decent Catering Kit into your filtered water

source container.

3. Connect the other, smaller white tube from the back of

the Decent Catering Kit into the back of the Decent

Espresso machine.

4. Plug the Ethernet cable into the back of the Decent

Catering Kit and connect it into the back of the Decent

Espresso machine. This will trigger the pump to refill

the water tray as needed.

5. Fill the water tray manually to get started, and flip the

power switch on the Decent Catering Kit. You should

see a light on the left side of the power switch. When

the pump refills the tank, you'll see another light on the

right side of the switch.

Kit into the back of the espresso machine.

What kind of water should I use?

To maintain the long-term health of your espresso

machine, use soft water with a low mineral content

(particularly low calcium). This can help to reduce scaling

inside the machine.

Search online for your local water quality report to find

the water pH and hardness versus softness. If you can’t

find that information, consider buying some water test

strips. The ideal pH is about 7.0.

We’ve seen many opinions about the right type of water

to use in the Decent Espresso machine. Here’s a short list

of what might work for you, depending on your region.

• Reverse Osmosis Water (RO)

• Bottled water, or fltered tap water

We recommend that you buy an inexpensive TDS meter

(Total Dissolved Solids). This meter can measure the

hardness of your water, which should be 120ppm or

lower to minimize scaling in your espresso machine.

A typical carbon filter does not reduce the hardness of

tap water. If your water measures over 120ppm,. you can:

• Install a water softener (a softener might not be

enough if your tap water is very hard)

• Install an RO filter (a safer solution, but it requires

multiple tools to install)

• Use bottled water.

• Use distilled water mixed with minerals

PART 3

Starting up

1. Plug the power cable into the back of the espresso

machine. Route the cable down through the slot

behind the machine. Then press the power switch to

turn the espresso machine on.

2. Connect the USB cable into the port on the front of

the machine. This will power the tablet. Attach the

other end of the USB cable into the tablet.

3. Stand by while the machine runs several self tests. This

includes pump and pressure tests. You'll see lights

going around the group head controller. During the

tests, you should also see a light activate on the front

of the machine. If the light doesn't go on, press the

emergency on/off button in the center to activate it.

This light will always go on when the machine is hot or

heating up.

Starting up

Plugging the power cable into the Decent machine.

Turn on the machine.

4. Wait until the machine is finished heating. The lights on

the group head will complete a full circle and then go

out. Then the machine is then ready to use.

5. Press the power button on the tablet to turn it on for

the first time. The tablet is charged before we ship it to

you, but if it loses some of its charge in transit, just

charge it again before using it.

6. Keep the Decent machine turned on and in sleep mode

when you're not using it, because the machine keeps

the tablet's battery charged. To learn more about

battery preservation or to make your Android battery-

independent in the future, see our "Battery-Free

Android Tablet Modification."

PART 4

Your first Decent espresso

Warm up the machine

1. Tap the Decent tablet screen to wake it up. It will say

"Wait" and the espresso machine will go into a warmup

mode. When it's finished, the screen will say "Ready."

2. Tap the Settings button in the lower-right corner of the

tablet screen.

3. Tap the Presets tab on the Settings screen. The presets

are a collection of brewing profiles. Choose the “Default"

setting or the "Gentle and Sweet."

4. Tap OK to return to the Home Screen.

We recommend that you use the same coffee profile for

about a week, with the same beans. This will give you a

chance to "dial in" your espressos to your taste and

reduce the number of variables.

Your first Decent espresso

The “Ready” button appears after the machine is

warmed up.

Choosing the “Default” preset

Weigh the coffee beans

You'll need a scale to weigh your coffee beans, because

the weight of the coffee grounds is essential to the

quality of your espresso.

In many cases, the weight of the beans (in grams) will be

equal the size of the basket, at least while you're getting

started.

The output of coffee is often 2:1 (twice as much coffee in

the cup as the bean weight in grams).

Your first Decent espresso

Weighing the beans on a scale.

Grind the beans

The grind density of your coffee is also important.

The finer the grind, the more flavor can get

extracted and the water will flow through the

grounds more slowly. And coarser grinds extract less

flavor.

But if the grind is too fine, the water might go too

slowly through the grounds and you won't get

enough coffee or it might taste bitter.

If a grind is too coarse, water will pour quickly

through the grinds, and your espresso might be too

weak or taste sour. For more information on

adjusting the grind, see our video "How to dial in

your grind."

1. Measure 18 grams of coffee for an 18g basket. If

the preset has a ratio of 2:1, it means that if you

put 18 grams of coffee in the basket, you should

get double the amount of coffee in the cup (36

grams).

2. Grind the coffee beans with a fine espresso

setting. You might need to experiment a little with

the grind to get exactly the right density.

Your first Decent espresso

Ground coffee pouring from a grinder into a

portafilter basket.

Rake and tamp the grounds

1. Use a puck rake to level the coffee grounds so

they fill the basket evenly. Level the mounds or

gaps, so the water flows equally throughout all the

grounds.

2. Use a tamper to tamp the grounds firmly into the

basket.

3. Wipe the edges of the portafilter so that there are

no loose grounds on it. You want the portafilter to

make a smooth seal on the espresso machine.

Your first Decent espresso

Stir the grounds with a puck rake to break up clumps

and level the coffee grounds in the basket.

Puck preparation: tamping the grounds

Pull your first espresso

1. Insert the portafilter under the group head and

turn it to the right, towards the group head handle.

2. Put a cup or glass under the portafilter. This is

where your coffee will pour.

3. Press the coffee icon on the group head of the

Decent espresso machine to start your espresso.

Steaming milk

Steaming and frothing milk is an art. If you've never

steamed milk before, we recommend that you

watch some videos first:

• Decent Espresso: Milk frothing tutorial

• Decent Espresso: Basic lesson on steaming milk

• Decent Espresso: How to ghost steam

Note: when you're finished steaming milk, and you

hit the "Stop" button on the group head, remove the

milk jug. The tablet will say "Wait." And in a couple of

seconds, a burst of pressure will clear the wand. Just

point the wand towards the drip tray.

Your first Decent espresso

Angle the milk jug and keep the wand close to the edge to

create a “whirlpool.”

Press the steam button (A) to start, and the stop button

(B) when the temperature reaches about 65° C.

Milk-steaming tips

• Keep the milk temperature between 60 degrees

Celsius/140 degrees Fahrenheit and 70 degrees

Celsius/150 degrees Fahrenheit. Exceeding those

temperatures can burn the milk.

• The placement and angle of the steaming wand is

key to getting the right density and texture to the

milk.

• The type of cup you pour the milk into will alter the

temperature. A ceramic cup may drop the milk

temperature by 10 degrees Celsius, and a paper

cup drops the temperature by 2 degrees Celsius. A

double-walled cup may lose 3 degrees Celsius.

Your first Decent espresso

Keep an eye on the milk temperature, and try to stop at

65° C.

The type of cup you choose affects coffee temperature

and how long it holds that temperature.

PART 5

Coffee-making variables

Some key variables for espresso

Watch our video: Espresso is difficult

Flow rate:

Depending on the type of espresso you make, the

flow rates and pressure will vary. For a drink with no

milk or very little milk, use a higher flow rate. For a

drink with more milk —!like a cappuccino or latte —

you want a "heavier" espresso, so the flow rate

should be slower.

Pressure:

The default 9 bars of pressure often produces a

more acidic espresso, such as the classic Italian.

Less pressure (lower bars) increases the body and

produces a more "chocolatey," richer flavor.

Temperature:

• Light roasts need higher temperatures.

• Medium or dark roasts use lower temperatures.

Coffee-making variables

Each coffee preset has defined settings already. If you

want to experiment, you can edit them in Settings.

Feedback on the Decent screen

The Espresso tab on the tablet screen gives you a

lot of feedback about your coffee.

What do the readings mean?

On the bar charts, the dotted line represents the

goal. The solid line shows what your brew is doing in

real time.

On the far right, you’ll see data about your coffee,

such as the preinfusion time, pouring time, and

weight of final coffee output.

Yes, the settings are editable

How to use Preset and Profile editor (Pressure/Flow

rate) page

Coffee-making variables

When you pull your coffee, the tablet displays some

of your results.

TIME: An ideal pour time is around 25s-30s, but this

cup poured in 20s. Some adjustments could be

made to lengthen that time.

WEIGHT: This preset is configured for a 2:1 ratio.

Ideally, 18 grams of coffee beans should output 36

grams of coffee (see right side, bottom). In this case,

the output was 35.4 grams of coffee (left side,

bottom).

The Decent Espresso presets

We include these presets on your Decent DE1 to

make it easy for you to emulate professional barista

recipes at the press of a button. You can also submit

your own espresso profiles in the Decent Diaspora or

download new profiles.

The recommended default values are for beginners.

They’re simply a "reasonable starting point.”! An

espresso made with those defaults should be good.

But it's also possible that changing the times, dose,

or grind setting could result in an even better coffee.

Going from "good to great" can take a bit of

experience, so we recommend that beginners start

with these presets.

PART 6

Cleaning

Daily clean

Be sure to watch the 22-minute video “How often /

to clean DE1.” for more detail on cleaning your

Decent machine.

Clean your Decent Espresso machine daily after you

use it by flushing it with clean water. You don't need

detergent for this daily cleaning. There are a couple

of ways to do this:

• Use the Decent “Forward Flush x5” preset (it’s in

the list of coffee presets)

• Use the Flush button on the group head controller

(on the left side).

Cleaning - daily

The Forward Flush x5 preset

The Flush button on the group head.

How to flush

1. Remove the grounds and rinse the portafilter.

2. Replace the coffee basket with a blind basket (a

basket with no holes in it). We include a blind basket

with your DE1.

3. Insert the portafilter with the blind basket into the

group head.

4. Apply your flush method -- the Flush button or

the “Forward Flush x 5” preset.

5. Wipe the shower screen on the underside of the

group head when you’re done.

Cleaning - daily

Changing baskets in the portafilter. Make sure you don’t

dislodge the small metal spring that holds it in place.

Cleaning with the Flush button

Press the Flush button on the left side of the group

head to activate the flush. A shot of clean, hot water

will pour through the group head filter. Best practice:

do it at least twice.

Cleaning with the Forward Flush preset

• Tap Settings > Presets > Forward Flush x 5

• Tap the coffee (preset) button on the group head.

The machine will cycle through five shots of hot

water into the blind basket.

• Change the preset back to your favorite coffee

setting and press “OK.”

One last rinse…

Remove the blind basket from the portafilter and

replace it with an empty coffee basket. Press the

Flush button again to rinse any remaining coffee

residue from the bottom of the group head.

Cleaning - daily

Rinse the group head again after you remove the blind

basket to remove any residue.

Clean the steaming wand

Wipe the steam wand daily and flush it with clean

water by filling a jug of clean water and steaming it

with the wand when you’re finished making coffee

for the day.

If you use a lot of milk, you can also soak the wand in

an alkaline cleaning solution. We recommend Urnex

Rinza. Pour one ounce of Rinza into your milk jug

and let the steaming wand soak in the solution for

about 10 minutes. Do not steam! When it’s done

soaking, pour out the Rinza and fill the pitcher with

water. Then steam the water as if it was milk.

Pour out the water, fill the jug again with more clean

water, and steam it one more time.

Cleaning - daily

Steam of jug of clean water to keep the steam wand

from getting clogged.

For stubborn clogs, unscrew the wand tip, soak it, and

run a needle through the hole.

Clean the water tank

Clean the ceramic water tank on your Decent

machine weekly.

Remove the tank and wash it with soap and water.

This removes some of the calcification and bacteria

that can accumulate in the tank.

If you have a countersunk model, turn off the refill

kit before you remove the water tank. Otherwise the

tank will start refilling with water when you pull out

the tray, and it will spill. You'll also need to tilt the

Decent machine up and carefully angle the tray out,

or lift the entire machine up and place it on a

counter to remove the water tray.

Drip tray

Clean the drip tray on your Decent machine weekly.

Remove the ceramic drip tray and cover, pour out

the waste water, and wash these parts with soap

and water.

Cleaning - weekly

On a countersunk model, you need to lift the machine to

remove the water tank after you remove the drip tray.

Steamer wand - weekly

This is an alternate approach to soaking the wand in

Rinza (as described on page 32).

To completely clean the steam wand:

1. Use Rinza (Urnex Rinza Alkaline Formula Milk

Frother Cleaner). Pour about 30ml into your milk

jug and add 500 ml of clean water, or dissolve

one tablet into water. Rinza is available in liquid or

tablet form.

2. Steam the jug with the Rinza-and-water solution

to clean out any milk residue from the steam

wand.

3. Pour out the solution and fill the milk jug with

clean water. Steam the water to rinse out any

remaining cleaning solution. Empty the water, put

more clean water in the jug, and steam it again.

Cleaning - weekly

Frothing the steam wand in a solution of Rinza and water.

Group head - flush with detergent

You should flush the underside of the group head

parts with detergent, using a blind basket to push

the detergent against the machine parts. We

recommend Cafiza cleaning powder.

To clean the underside of the group head:

1. Insert a blind basket in the portafilter and put a

tablespoon of Cafiza powder in it.

2. Put the portafilter on the drip tray and flush a

little water onto it to help dissolve the powder.

Swirl it around.

3. Put the portafilter (with the detergent) into the

group head.

Cleaning - weekly

Put a tablespoon of detergent into the blind basket of

your portafilter.

Add a little water to the detergent to make suds before

you insert the portafilter into the group head

4. Press the "Forward Flush x 5" preset (in Settings >

Presets) and flush five times. It will flush the

detergent from the blind basket up towards the

group head.

5. After you've poured the detergent out of the

portafilter, continue to backflush the group head

with water to remove the detergent residue.

When you don’t see suds in the blind basket

anymore, replace it with a coffee basket and flush

with water again.

WARNING: Do NOT put detergent in your water

tank! You could damage the internal heater. You’ll

use food-grade citric acid to clean and descale

through the water tank.

Cleaning - weekly

You’ll see some sudsy water in the drip tray, which exits the

machine through a relief valve.

Watch this video for more details!

Remove parts from the group head

You'll remove some parts under the group head for

this cleaning, so you need a small screwdriver. For

reference, watch the group head cleaning segment

of our video.

1. Turn off the Decent machine.

2. Remove the drip tray.

3. Remove the center screw from the screen at the

bottom of the group head opening. You might

need to use a mirror to see what you're doing.

After you remove the center screw, you can

remove two parts: the shower screen, and the first

diffuser. This leaves one more diffuser to remove.

Cleaning - monthly

This center screw holds the shower screen in place,

and the first diffuser behind it.

The first diffuser is held in place with the same screw. The

second diffuser is held in place with three screws.

4. Remove the second diffuser by removing the

three screws that attach it to the group head.

5. Wipe the underside of the group head in the

machine after you've removed the three parts

(the shower screen and the two diffusers).

Cleaning - monthly

The placement of the three screws in the last diffuser. Be

careful not to damage the temperature probe during the

cleaning or parts removal process.

Soak the group head parts in detergent

1. Put the three parts into the drip tray and add 15

grams of group head cleaning detergent (such as

Cafiza powder) and about 500 grams of hot

water.

2. Let the parts soak overnight, or for a few hours. Be

sure to store the screws someplace where they

won't get lost!

3. Throw the water and cleaning solution away after

it's done soaking, and rinse all the parts with fresh

water.

Cleaning - monthly

Soak the parts in water and detergent (such as

Cafiza) for espresso machines).

Replacing the group head parts

1. Replace the inner diffuser first, with the three

screws. Be sure that you align the "probe" hole in

this diffuser over the probe in the group head

controller, and be careful not to break it.

2. Replace the second diffuser and be sure that the

indentations align properly. There are two small

plastic knobs in this diffuser that should fit into

two holes in the other diffuser. And there's

another small hole that fits over the probe. If it

doesn't fit easily, you might not have aligned it

correctly.

3. Hold the diffuser in place and then add the metal

shower screen on top of it. Put the center screw

back through the screen and through the inner

diffuser to attach them to the group head.Soak

the parts in water and detergent (such as Cafiza)

for espresso machines).

Cleaning - monthly

The center diffuser being replaced on top of the second

diffuser. It will be held in place with a center screw, along

with the shower screen

Descaling

Descaling removes mineral deposits that can build

up inside your espresso machine and affect its

performance. If you use hard water in your region,

you might have to descale more often.

What you need

•Water: 1500 ml (1.5 liters) of water. This is

approximately 6 quarts of water.

•Citric acid: 38-80 grams (approximately 3-6

tablespoons)

Cleaning - descaling

Use food-grade citric acid for descaling your espresso

machine.

Prepare the citric acid solution

1. In Settings, tap "Machine" tab (at top) and select

“Descale.”

You’ll see a screen on your Decent tablet with

instructions to use 1.5 liters of water and 300

grams of citric acid powder. This might be more

citric acid than you need. Some customers use

much less citric acid — from 38 to 80 grams.

2. Remove the drip tray and cover, and then remove

the water tray. If you use a refill kit, turn it off

before removing the water tray.

3. Pour all the water out of the water tray and wash

it. Then fill it with 1500 ml (6 quarts) of clean,

filtered water.

4. Add 3-6 tablespoons (about 38-80 grams) of

citric acid powder to the water and stir.

5. Lift the lever in the back of the machine and slide

the water tray back into place. Keep the refill kit

turned off (if you use one). Replace the drip tray.

Angle the steamer wand into the drip tray.

Cleaning - descaling

Tap Settings > Machine > Descale.

Start the descaling process

1. Put a blind basket into the portafilter and insert it

into the group head.

2. On the tablet, tap "Descale now" on the Descaling

screen.

3. You'll hear pressure build up in the machine. After

a few minutes, water will start draining out of the

machine and from the steamer wand. The process

takes about 10-12 minutes. When it stops, you'll

be returned to the main Descaling screen again.

4. Tap "Cancel" on the Descaling screen to exit that

mode.

5. Remove the drip tray and the water tray. Empty

the water tray with the citric acid in it, wash it, and

fill it with clean, filtered water. Slide it back into

place and replace the drip tray. If you use a refill

kit, turn it back on.

6. Remove the blind basket from the portafilter and

replace it with a coffee basket. Insert the

portafilter back into the group head.

Cleaning - descaling

Rinse thoroughly after descaling

Now you're going to flush the system with clean

water many, many times. Keep flushing until you've

flushed the citric acid out.

1. Press the "Flush" button repeatedly, and flush at

least one tray of water through the machine. If the

exhaust still tastes like citrus, flush another water

tray.

2. Fill the milk jug with clean water several times and

froth the water with the steam wand until the

water looks clear. Keep the tip off the wand until

you're finished, and then screw it back on.

PART 7

Troubleshooting

Common errors and solutions

These are a few common errors that might occur

after you've had your Decent machine for awhile.

Your tablet shows a large group of

people asleep in their chairs

This "sleeping" image on your screen indicates that

there's a Bluetooth connection issue with your

tablet. Press the “off” button to reboot the tablet and

see if that fixes the issue. If not, reboot the Decent

Espresso machine.

Troubleshooting

When you see this image on your tablet and can’t wake it up,

you need to reboot your tablet and your Decent Espresso

machine.

Unreliable Bluetooth

If rebooting your tablet or DE1 doesn’t resolve a

Bluetooth issue, you might need to reset Bluetooth

on your Android. Our video shows you how.

Low battery message

If you see a message that says your tablet's battery

is very low (and your Decent espresso machine is

already turned on), try unplugging and replugging

the charging cable that connects your tablet to the

espresso machine.

Troubleshooting

See our video “How to completely reset Bluetooth on your

Android tablet.”

Unexpected flow rates or coffee

volume output

Do you have a Bluetooth scale connected to your

espresso machine? Check to see if it's touching the

front of the machine. The vibration from the

machine might cause it to calculate the weight

incorrectly, and this would affect the water output.

Reinstalling your de1app

If you accidentally delete your de1app, or if your

tablet got reset and you need to reinstall it, see our

video “How to install de1app directly from your

tablet.”

Troubleshooting

You can also cause weight inaccuracies if you don’t center

your cup on the scale.

Basket - The metal basket that inserts into the

portafilter to hold the coffee grounds.

Channeling - When water pours through an open

path in the coffee grounds instead of flowing evenly

across them. This can happen when the coffee is

tamped unevenly, leaving gaps or weaker spots in

the puck and it can impact the flavor of the

espresso.

Flow rate - The measurement of how much water

passes through the group head while the pump is

working. It's measured in ml/s.

Group head - The round-shaped front of the Decent

Espresso machine, which holds the portafilter and

through which espresso gets extracted.

Portafilter - Looks like an ice cream scoop with its

long handle. It holds the basket of coffee grounds in

the group head so that hot water can pour through

the grounds.

Preinfusion - Letting some water into the puck at a

lower pressure rate before extracting your espresso.

Measured in seconds.

Puck - The round disk of damp coffee grounds left

in the portafilter basket after you've extracted an

espresso.

Tamper - A tool that compresses the grounds into

the basket
