Saving energy
Set the desired warm water temperature directly on the
flow-through heater.
Mixing with cold water at the armature for water that is too
hot consumes unnecessarily water and energy.
At approx. 40 °C (temperature selection position
unit operates most economically.
A fault, what to do?
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 temperature is
not reached.
The water is not sufficiently warm.
From time to time, cold water
flows out.
Winter operation:
The desired water temperature
leaving the tap is no longer
reached.
EN
Cleaning
Simply wipe the appliance with a damp cloth.
Do not use intensive or abrasive cleaning agents.
) the
Cause
The filter in either the water tap or
the showerhead is clogged
The filter in the corner regulating
valve is clogged.
The filter upstream from the check
valve in the cold water supply inlet
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 house electrical in-
stallation 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
is too low.
The air sensor in the appliance de-
tects air in the water and momen-
tarily switches the heating element
off.
The supply temperature has
reduced.
Solution
Remove the filter and either
clean it or descale it.
Get a servicing expert to clean the
filter.
Remove the filter and either
clean it or descale it.
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 angle valve to regulate the
flow-rate.
Check the flow-rate limiter or re-
place it with a smaller one.
Check the fuse in the house electri-
cal installation.
Get the appliance's automatic cir-
cuit breaker checked by an electri-
cian. Check the permissible supply
temperature.
By a qualified professional:
use the angle valve to regulate the
flow-rate.
Check the flow-rate limiter or re-
place it with a smaller one.
After a few seconds, the continu-
ous-flow heater automatically goes
back into operation.
Reduce the water flow on the taps
until the desired water temperature
is reached.
