23  Descaling
To ensure that your appliance continues to operate cor-
rectly, it must be descaled regularly.
How frequently you need to run the descaling pro-
gramme depends on the water hardness and how
many times you have used the steam-assisted opera-
tions. The appliance indicates when only another 5 or
fewer steam-assisted operations are possible. If you do
not carry out descaling, you can no longer set any op-
eration with steam.
Descaling comprises several steps and takes
approximately 70 - 95 minutes:
¡ Descaling (approx. 55 - 70 minutes)
¡ First rinse cycle (approx. 8 - 12 minutes)
¡ Second rinse cycle (approx. 8 - 12 minutes)
Carry out descaling in full.
If descaling is interrupted, you can no longer set any
operation. To ensure that the appliance is ready for op-
eration again, carry out 2 rinse cycles.
23.1 Preparing descaling
ATTENTION!
The length of time for which the descaler is left to work
is based on the recommended, liquid descaler. Other
descalers may damage the appliance.
Only use the liquid descaler recommended by us
for the descaling programme.
If descaling solution comes into contact with the control
panel or other delicate surfaces, it will damage them.
Remove descaling solution immediately with water.

ment following operation with steam or microwave-only
