A fault, what to do?
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.
Fault
Water flow-rate is too low.
The desired water tempera-
ture is not reached.
The water is not sufficiently
warm.
From time to time, cold
water flows out.
Winter operation:
The desired water tempera-
ture leaving the tap is no
longer reached.
The appliance does not
start (heat), no water flows.
If the fault could not be eliminated, please call customer service.

the showerhead is clogged
The filter in the heating system is
clogged.
The continuous-flow heater is
connected to a thermostatically-
controlled water tap.
The power limit has been reached.
Water flow-rate is too high and/or
the cold water supply temperature
is too low.
The fuse in the fusebox has
tripped/blown.
The appliance's automatic circuit
breaker has been tripped.
The power limit has been reached.
Water flow-rate is too high and/or
the cold water supply temperature

Solution
Remove the filter and either
clean it or descale it.
Get a servicing expert to clean the
filter.
Set the temperature on the continu-
ous-flow heater to "max".
Reduce the flow-rate at the water tap
supply.
By a qualified professional:
use the corner valve to regulate the
flow-rate.
Check the flow-rate limiter or replace it
with a smaller one.
Check the fuse in the fusebox.
Get the appliance's automatic cir-
cuit breaker checked by an electri-
cian. Check the permissible supply
temperature.
By a qualified professional:
use the corner valve to regulate the
flow-rate.
Check the flow-rate limiter or replace it
with a smaller one.
After a few seconds, the continuous-
flow heater automatically goes back
into operation.
Reduce the water flow on the taps
until the desired water temperature is
reached.
Starts rinsing:
Open the warm water tap and
allow water to flow for at least
1 minute (flow-rate at least 6 litres per
minute). 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.
