A Fault, What To Do - Siemens BK20100M Handbuch

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.
Cleaning
Simply wipe the the housing and the mixer tap
with a damp cloth. Do not use acidic or abrasive
cleaning materials.
Descaling the appliance
The device must be descaled if the following situa-
tions apply after selecting the maximum tempera-
ture setting:
– the water does not come to the boil,
– heater and pilot lamp switch off and on at inter-
vals without the buzzer sounding,
– the flow of hot water out of the outlet pipe is
significantly slower.
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 commer-
cially 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.
en
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?

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 inte-
grated 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.
