Fault Cause Solution
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.
A high water temperature is set,
but it is not reached. The continuous-flow heater is connected to
a thermostatically-controlled water tap. Set the temperature on the continuous-flow heater
to “60 °C”.
The display is blank. The fuse in the fusebox has tripped/blown. Check the fuse in the fusebox.
The water is not warm. The supply temperature has reduced. Reduce the water flow on the taps until the desired
water temperature is reached.
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
temperature (e. g. due to pre-warmed water supplied
from a solar water heater). The thermostatic premixer in the domestic supply
must be set accordingly to lower temperatures.
Lights up in the display. The power limit has been reached. Reduce the water flow at the tap or lower
the temperature setting on the appliance.
