After the heater has cooled down, it is ready for use again.
The temperature at which the heater switches off can vary,
although the setting remains the same, due to:
•
internal furring,
•
different volumes of water in the tank,
•
using the heater again before it has cooled down.
5.3.2 Saving energy
Only heat the amount of water that you actually require. Run the
water out of the heater as soon as it has reached the selected
temperature.
5.3.3 Cleaning
•
Simply wipe the housing and the mixer tap with a damp
cloth. Do not use acidic or abrasive cleaning materials.
5.3.4 Descaling the appliance
The device must be descaled if the following situations apply
after selecting the maximum temperature setting:
•
the water does not come to the boil,
•
heater and pilot lamp switch off and on at intervals without
the buzzer sounding,
•
the flow of hot water out of the outlet pipe is significantly
slower.
CAUTION:
Attention!
Descaling agents can be corrosive! Wash off any spillage with
water immediately! Observe the instructions for use provided
by the manufacturer.
Descaling procedure
•
Fill the tank with a 1/2 litre of cold water.
•
Pull out the descaler drawer as far as the stop.
•
Pour in approx. 100 ml (small bottle) of commercially
available descaling liquid suitable for use on water boilers,
and add a little water.
If the furring is quite severe, increase the amount of
descaling liquid accordingly (max. 150 ml).
•
Push the descaler drawer all the way into the heater.
•
Adjust the temperature selector to the middle setting and
switch on. Allow the solution to react for 15 minutes.
•
Next, top up the tank to the 5-litre mark, heat the water
again and wait 30 minutes while descaling takes place.
•
Slightly open the tap for filling the tank with cold water,
so that the descaling solution is slowly flushed out through
the overflow where it also dissolves any scale in the pipe.
•
After about 5 minutes, drain the tank and then rinse it out
several times with fresh water.

A fault, what to do?
CAUTION:
Attention!
Repairs to electrical appliances must only be carried out by
an authorised technician. Improper repairs can lead to risk of
serious injury to the user.
If the pilot light comes on at regular intervals when the heater is
empty, this indicates that the integrated safety thermostat is
protecting the appliance from overheating.
•
Switch the heater off (turn the temperature selector fully
anti-clockwise
).
If the pilot light comes on at intervals although the heater is
switched off:
•
Unplug the appliance from the mains and call Customer
Service.

Customer Service
If you encounter a problem, please check the following before
calling Customer Service:
•
Is the heater plugged in?
•
Is the fuse in the domestic wiring in order?
•
Has the heater cooled down sufficiently since the last time
it was used to boil water?
You will save yourself the costs of an unnecessary visit by
customer service personnel.
We ask you to always provide the
E-No.
and the
FD-No.
of your
appliance when calling in a customer service engineer. You will
find these numbers on the underside of the water heater.
