Boiling dry destroys the high limit safety cut-out and the
controller-limiter combination must then be replaced.

Material losses
If a heat exchanger is installed in the same cylinder, you
must limit the maximum temperature for this heat ex-
changer. This prevents the high limit safety cut-out of the
threaded immersion heater from responding.

12. Troubleshooting
Note
The high limit safety cut-out can respond at temperatures
below –15 °C. The appliance may be subjected to these
temperatures during storage or transport.
fault
Cause
Remedy
The water does not
heat up.
The high limit safety
cut-out has responded
because the controller
is faulty.
Remedy the cause of
the fault. Replace the
controller-limiter com-
bination.
The high limit safety
cut-out has responded
because the temperature
has dropped below -15 °C.
Press the reset button.
The high limit safety cut-
out has responded be-
cause a heat exchanger
in the same cylinder is
set too high.
Limit the maximum
temperature of the heat
exchanger.
The flanged immersion
heater is faulty.
Replace the flanged im-
mersion heater.
The safety valve drips
when the heating is
switched off.
The valve seat is con-
taminated.
Clean the valve seat.
