Before starting, disconnect from the main power by pulling out oft he plug.
Remove the sound-proofing casing on the underside
of the appliance. To remove, loosen the middle fixing
screw by hand, which will enable you to fold down,
detach and remove the sound-proofing casing.
Place a suitable container under the appliance and

Drain the reservoir and then screw the drain plug back
in and tighten slightly.
Unscrew the probe cap (1) by pressing down and turning

For thorough cleaning and descaling of the probe cap we
recommend: 0.1 litres of beam descaler and 0.5 litres
water (total 0.6 litres of descaling mixture).

put the probe cap into the mixture.
