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 Cause Solution Who
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 regulating
valve is clogged. Get a servicing expert to clean the
filter. Servicing

The desired water temperature is
set, but it is not reached. The continuous-flow heater is
connected to a thermostatically-
controlled water faucet. Set the temperature on the continu-
ous-flow heater to “60 °C”. Customer

cal installation. Customer
From time to time, cold water
flows out. The air sensor in the appliance de-
tects air in the water and momen-
tarily switches the heating element
off. After a few seconds, the continu-
ous-flow heater automatically goes
back into operation. Continuous-

problem
The set temperature, for instance
41.0 °C flashes. The temperature
of the water leaving the tap is
higher than the set temperature. The temperature of the water
supplying the continuous-flow
heater is higher than the set tem-
perature (e. g. due to pre-warmed
water supplied from a solar water
heater). The thermostatic premixer in the
domestic supply must be set ac-
cordingly to lower temperatures. Customer
Winter operation:The desired wa-
ter temperature 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
E02 No thermostatic premixer available
The supply temperature to the
continuous-flow heater is higher
than 55 °C (e. g. due to pre-warmed
water supplied from a solar water
heater). Install a thermostatic premixer in
the domestic supply. Customer
