water flows more water pressure is not sufficient
slowly than expected
dirt in the pipes
the heater switches water pressure is varying,
itself on and off flow rate is too low
electric supply incorrect
circuit breaker has tripped
water remains cold,
safety thermal cut-out has tripped
although the appli-
faulty heating element
ance switches on
one phase is not connected
water connections mixed up
appliance does not
switch on and the water pressure is not sufficient
water remains cold
dirt in the pipes

hot water tempera-
ture varies

replace heating element (by authorized technician)
check the supply voltage (2/PE 400 V - MH/MDH 7
only)
check installation
adjust the water flow (see fig. 7)
open the shut-off valve, check water pressure
remove dirt from the inlet and outlet pipes
stabilise the water flow pressure
avoid using other taps in the same circuit
(i.e. toilets, washing machines)
check the supply voltage
adjust the flow either at the tap, the valve or the
flow adjustment screw
measure the temperatures and flow rate and compare
with the technical data, check the power supply
