Preparation

Brewing Coffee

1. Install the Drip Tray on front of the Diamo One if

desired.

2. Wash the Water Tank with warm soapy water.

3. Fill the tank with water.

(Maximum capacity: 37 oz. / 1.1L)

4. Place the full tank on the back of the Diamo One. You

must have the tank lid OPEN in order to slide it fully
into place.

5. Close tank lid.

6. Plug in the power cord.

HELPFUL TIP: Before brewing your first cup, we recommend

running through the instructions below with just water for a
practice run or two. This will help avoid any mishaps
later! Place a cup under the spout and collect any water
as it comes out. When you practice with the steam tube,

make sure you submerge the tip first!

1. Turn the Coffee/Steam Knob to the “Coffee” position

then push the Power button. The Power button LED
will flash red while it pre-heats. The Power button
LED will turn solid green when pre-heating has
finished.

2. Use the Coffee Strength Dial to adjust the strength of

your brew. Setting number 1 will produce the weakest
brew while 3 produces the strongest.

3. Place your cup on the drip tray underneath the spout.

4. Slide open the E.S.E Pod Slot Cover, drop your pod

into the slot, and close the cover.

4

5. Select the brew that you want:

Espresso:

Press the Single button

for a 1.5 oz. (45 mL) shot.

Lungo:

Press the Double button for a 3.7 oz. (110 mL) shot.

Americano:

Press and momentarily hold BOTH the Single and

Double buttons for a 2.4 oz. (72 mL) shot followed by

2.4 oz. (72 mL) of hot water. When making an
Americano, there is a 2-3 sec pause between the
coffee shot and water shot as the coffee pod is moved
into the Recycle Box. Be sure to wait until the second

shot is fully finished before removing your cup.

6. When finished, power off your Diamo One. To power off

your Diamo One, press the Power button, then release.
The Power button should go dark.

Helpful Tips

• Start with the Coffee Strength Dial on #2 and adjust

to your liking. E.S.E. pods from different
manufacturers may require some adjustment to get
your preferred taste.

• When brewing, the Diamo One makes pumping
noises due to the pressures involved. This is normal.

• Keep your Diamo One working and clean by running
a rinse cycle into an empty cup (Push Single without
inserting a coffee pod) and emptying the Pod
Recycle Box after every eight brews. If the Single
(Espresso) LED is flashing slowly, it is time to run a
rinse and empty the Recycle Box.

Frothing Milk

1. With the power on, turn the Coffee/Steam Knob to the

“Coffee” position, then push the Steam button . The
Steam button will light up a steady blue and the
Power button will flash red while the Diamo One
heats up. When the Power button turns green, you
are ready to continue.

2. DO NOT TOUCH THE STEAM TUBE while foaming or for

three minutes afterwards. It gets very hot. Use the
rubber grip if you need to move the tube.

3. It is recommended that you prime the steam pump

prior to steaming. To do so: Position a cup under
the Steam Tube and turn the Coffee/Steam Knob to the
“Steam” position. A small amount of water will shoot
out of the tube as the steam builds up. It takes about
ten seconds for steam to come out. Turn the Coffee/
Steam Knob to “Coffee” to stop the steam.

4. Put milk into your frothing cup and place it under the

steam tube. Make sure the head of the Steam Tube is
below the surface of the milk to avoid splashing or
spraying. Once the tip of the Steam Tube is below the

surface of the milk, turn the Coffee/Steam Knob to
“Steam” to start frothing your milk. When you have
enough foam, turn the Coffee/Steam Knob back to
“Coffee” to stop the steam.

5. To finish the steam cycle and clean out the Steam Tube,

put a cup under the Steam Tube, press the Steam
button and turn the Coffee/Steam Knob to “Steam.”
Water will again shoot out of the nozzle. Count for five
seconds and turn the Coffee/Steam Knob back to
“Coffee” to stop. This must be done after every use of
the Steam Tube to avoid clogging. When cool, clean
the Steam Tube with a wet cloth or sponge. It is
recommended to thoroughly clean the Steam Tube
after use (See Cleaning the Steam Tube on page 11).

6

Heating Hot Water

6. You may now power down the Diamo One or brew

something else.

Helpful Tips

• If your frothing cup is too tall, position the Diamo
One so that the steam tube is off the edge of the
counter.

• Any milk or milk alternative will froth with practice.
Lower-fat milk is easier to froth without burning.
Higher-fat milks provide a richer taste but are more
challenging.

• The milk should almost double in volume when
properly frothed and the bubbles should be very
small (microfoam). Move your cup around to get
uniform foam. Big bubbles indicate overheating.

• If using a thermometer, the ideal temp is 150-155°F
(66-68° C).

1. With the power OFF, turn the Coffee/Steam Knob to the

“Coffee” position, then push the power button. The
power button’s LED will flash red

as it pre-heats.
When pre-heating is done, the LED will turn green
and you may continue to the next step.

2. Place your cup under the steam tube so that the tube is

well within the cup and then turn Coffee/Steam Knob to
the “Steam” position. Caution: Hot water will squirt out
of the nozzle. When you have enough hot water, turn
the Coffee/Steam Knob back to the “Coffee” position to
stop the hot water.

3. DO NOT TOUCH THE STEAM TUBE without using the

rubber grip. Wait at least three (3) minutes after

making hot water to touch the bare metal for it to cool
off.

7

You can adjust the amount of water provided by each of
the Diamo One’s buttons if your cups are larger or smaller
than the default setting. See the table below for default,
minimum, and maximum amounts. Continue reading to
learn how to change those settings.

Note: The Americano setting is determined by how you set
the Single (Espresso) amounts. The formula is
(1.6 x Espresso Settings) + (1.6 x Espresso Settings).

Lastly, when changing settings, we strongly
recommend that you do not do so with a coffee pod in
place. Just run straight water so there is no waste.

Changing the amount for Single (Espresso):

1. Power on the Diamo One and wait for it to pre-heat

as normal.

2. When pre-heating is finished

(Power LED is green), press and
HOLD the Single (Espresso) button.

Turning Off

1. To power off your Diamo One, press the Power

button, then release. The Power button should go dark.

Changing the Amount Brewed per Cup

Default Amount Minimum Amount Maximum Amount

Single (Espresso) 1.5 oz. (45 mL) 1 oz. (30 mL) 2 oz. (60 mL)

Double (Lungo) 3.7 oz. (110 mL) 2 oz. (60 mL) 10.1 oz. (300 mL)

Americano 4.9 oz. (144 mL) 3.2 oz. (96 mL) 6.5 oz. (192 mL)

3. Hot water will come out of the spout for as long

as you hold down the button OR until the maximum
amount in the table on page 7 is reached.

4. Let go of the button when the desired amount of water

is in your cup.

5. The amount is now set.

6. Empty your cup and use the Single (Espresso) button as

normal, but without a coffee pod to test it out.

7. If the amount dispensed is different, repeat step 6. The

amount should now match what you set.

Changing the amount for Double (Lungo):

1. Power on the Diamo One and wait for it to pre-heat as

normal.

2. When pre-heating is finished

(Power LED is green), press and HOLD
the Double (Lungo) button.

3. Hot water will come out of the spout for as long as you

hold down the button OR until the maximum amount
from the table on page 7 is reached.

4. Let go of the button when the desired amount

of water is in your cup.

5. The amount is now set.

6. Empty your cup and use the Double (Lungo) button as

normal, but without a coffee pod to test it out.

7. If the amount dispensed is different, repeat step 6. The

amount should then match what you set.

9

Changing the amount for Americano:

The Americano process depends on the following formula:

Amount dispensed for Americano = (Espresso setting x 1.6) +
(Espresso setting x 1.6)

Example: If you have your Espresso set for 45 mL, you’ll get
approximately: (45 x 1.6) + (45 x 1.6) = (72) + (72) = 144mL
in total

Reset the Settings:

To set all amounts back to their default setting:

1. Power on the Diamo One.

2. Once it has pre-heated (Power LED is green), you
must hold down three buttons—Steam, Single, and
Double. Doing so can inadvertently start the
“Americano” brewing process, so start with the
Steam button, then quickly also press and hold the
Single and Double buttons.

3. Hold the Steam, Single and Double buttons for
approximately five seconds until ALL FOUR buttons
(three held plus the Power button) flash three times,
then let go. All volumes are now reset to the default
values listed on page 7.
