be set warmer than
42 °C.
The desired water tem-
perature is set, but it is
not reached.
The display is blank.
The water is not warm.
From time to time, cold
water flows out.

instance 41, blinks. The
temperature of the water
leaving the tap is higher
than the set tempera-
ture.

If the fault could not be eliminated, please call customer service.
Cause
The filter in either the water tap
or the showerhead is clogged.
The filter in the corner regu-
lating valve is clogged.
The continuous-flow heater has
reached the power limit.
The child protection feature
is activated.
The continuous-flow heater
is connected to a thermo-
statically-controlled water
faucet.
The fuse in the house electrical
installation has triggered/blown.
The appliance's automatic cir-
cuit breaker has been triggered.
The fuse in the house electrical
installation has triggered/blown.
The air sensor in the appliance
detects air in the water and mo-
mentarily switches the heating
element off.
The temperature of the water
supplying the continuous-flow
heater is higher than the set
temperature (e.g. due to pre-
warmed water supplied from
a solar water heater).
Deposits may have built up in
the appliance.
Solution
Remove the filter and either
clean it or descale it.
Clean the filter.
Close the water tap some-
what so that the less water
flows through.
To deactivate child pro-
tection, see "How to operate
the continuous-flow heater –
Setting a temperature limi-
tation/child protection"
The temperature at the con-
tinuous-flow heater must be
set to 60 °C.
Check the fuse in the house
electrical installation.
Check the appliance's auto-
matic circuit breaker.
Check the fuse in the house
electrical installation.
After a few seconds, the
continuous-flow heater auto-
matically goes back into
operation.
Mix in cold water at the water
faucet supply.
Open the warm water tap
fully to the warmest possible
setting and let the water flow
for one minute. Repeat as
necessary.
