A fault, what to do?
WARNING:
Attention!
Repairs must only be carried out by an authorised technician.
Improper repairs can lead to risk of serious injury to the user.
If your appliance does not operate as required, it is often due
to a very minor problem. Please check whether you can remedy
the fault yourself by using the following guidelines. You will save
yourself the costs of an unnecessary visit by customer service
personnel.
If the fault could not be eliminated, please call customer service.
Fault
Cause
Solution
Who
The appliance does not start
(heat), no water flows.
The fuse in the house electrical
installation has tripped/blown.
Check the fuse in the house electrical installation.
Customer
Power failure or initial start-up.
Starts rinsing:
Open the warm water tap and allow water to flow for
at least 30 seconds (flow-rate at least 2 litres per min-
ute). Only then (for safety reasons) will the appliance
begin to heat.
Should the appliance not start because of a reduced
flow-rate, remove the perlator, shower head or similar
before start and repeat the process.
Customer
The air sensor in the appliance
detects air in the water and
momentarily switches the
heating element off.
The desired water temper-
ature leaving the tap is no
longer reached.
The supply temperature
has reduced.
Reduce the water flow on the taps until the desired
water temperature is reached.
Customer
Water flow-rate is too low. The filter in either the water
tap or the showerhead is
clogged.
Remove the filter and either clean it or descale it.
Customer
The filter in the corner regulat-
ing valve is clogged.
Remove, clean and reinstall the filter. Circulate water
through the appliance. If necessary, repeat this proce-
dure until the filter is free of particles.
Servicing
expert
The water is not sufficiently
warm.
The appliance‘s automatic cir-
cuit breaker has been tripped.
Get the appliance’s automatic circuit breaker checked
by an electrician. Check the permissible supply tem-
perature.
Servicing
expert
Water flow-rate is too high
and/or the cold water supply
temperature is too low.
Use the angle valve to regulate the flow-rate.
Check the flow-rate limiter or replace it with
a smaller one.
