Priming After Long Periods of Non-Use

For the best tasting espresso, prime the espresso machine with fresh
water after a long period of non-use. Priming will also ensure that
the boilers are filled and the espresso machine is ready to operate.

Remove the reservoir, empty any stale water, replace, and fill

the reservoir with fresh water to the max fill line.

Fill the boilers with the fresh water. For instructions, see “Fill and

Rinse the Boilers” on page 13.

Descaling

Calcium deposits (“scale”) from water will build up in the espresso
machine over time and may impair espresso quality. Scale should be
removed every four months; local hard-water conditions may require
more frequent descalings. Use a packaged descaling agent or
appropriate decalcification tablets to remove scale.

Remove the shower screen from the brew head. See “Cleaning

the Shower Screen” on page 24 for instructions.

Make certain the water reservoir is empty. Following the

directions on the descaling agent packet, mix the descaling
solution and add it to the reservoir.

To catch the cleaning solution, place a large cup under the

brew head (do not attach the portafilter), and another under
the frothing nozzle.

Press the On/Off Power Switch to turn the espresso machine

on. It is not necessary for the boilers to heat before proceeding
to the next step.

Press the Espresso Button and dispense cleaning agent

through brew head for 15 seconds; press the Espresso Button
again to shut off.

Open the Steam Dial by turning it counterclockwise, then press

and hold the Hot Water Button for 15 seconds to dispense
cleaning agent through the frothing arm and nozzle.

Press the On/Off Power Switch to turn the espresso machine off.

Wait 20 minutes, then repeat steps 4–7. Every 20 minutes,

keep repeating steps 4–7 until nearly all the solution in the
reservoir has been run through the espresso machine. Do not
allow the reservoir to run completely dry.

Remove the water reservoir and rinse with fresh water, then

replace and fill with fresh water to the max fill line. Press the
On/Off Power Switch to turn the espresso machine on, and flush
the espresso machine by quickly dispensing the contents of the
reservoir, alternating between the brew head and frothing arm.
Do not allow the water reservoir to run completely dry.

Attach the shower screen to the brew head. See “Cleaning the

Shower Screen” on page 24 for instructions. Be sure to add
additional fresh water to the reservoir for brewing.
