IMPORTANT - You cannot terminate the descaling program prematurely. Leave
the program run until the complete cycle is finished and the appliance switches
off automatically. You need a large vessel (for at least 2.5 litres) fitting under the
group head. The descaling cycle will require up to 45 minutes.
1. Switch off the appliance via the power button and unplug. Then clean the appli-
ance (see above).
2. Prepare approx. 2500ml descaling solution according to the instructions on the
pack.
IMPORTANT - It is important to fill the water tank with the correct amount of des-
caling solution. Otherwise, the machine would completely empty the water tank.
This could damage the pump!
3. Pull the water tank upwards and out of the appliance and empty the water tank.
Remove the water filter and place the water filter into a bowl with clear tap
water.
4. Rinse the water tank with clear tap water. Then fill the descaling solution into the
water tank. Wipe dry the exterior of the water tank and re-install the water tank
at the back of the appliance (see: 'Operation / Filling the Water Tank').
5. Ensure that the drip tray is empty and inserted correctly. Place a heat-resistant
vessel of sufficient size (at least 2500ml) under the group head and direct the
steam wand into the vessel.
6. Plug in the power plug. For starting the de-scaling program press the 1 cup but-
ton, 2 cups button, and power button simultaneously for approx. 3 seconds.
The descaler solution comes out from the steam wand and the group head. Both
espresso buttons are flashing.
NOTE
The descaling program removes lime deposits from the water system by automati-
cally performing a series of rinses and pauses until the water tank is almost empty.
At the end of the descaling process the espresso buttons get dark, but the desca-
ling indicator flashes. Remove the water tank. Empty the water tank completely
and rinse thoroughly with clear tap water. Thereafter, fill the water tank again with
clear tap water. Ensure that the exterior of the water tank is dry and replace the
water tank at the rear of the appliance.
7. Remove and empty the vessel holding the descaling solution. Then replace the
vessel under the group head. Direct the steam wand into the vessel.
8. Hold the power button and both espresso buttons (1 cup button and 2 cups
