Fault lock-out

The heater is able to identify faults on individual components and during
the operation.
The Control Panel gives out the fault code in a flashing mode.
After a series of 5 fast GREEN flashes, the fault code output will be a
repeated sequence of long RED flashes. The meaning of the number of red
flashes is shown in the following table.
After that, again there will be 5 fast GREEN flashes.

Rectify the cause of the fault.
To reset the fault, switch the heater off and on briefly (at least
5 seconds).
If serious malfunctions such as overheating or failure to start reoccur, the
heater is locked and can be put back into service by deleting the
failures.
Do this by disconnecting the power supply (e.g. by removing all 3 fuses)
while the appliance is switched on (see Operating Instructions, mode
selector knob in position 1, 2, 3, 4 or 5), but the heater is not running (to

If a fault occurs, the heater stops. In case of electrical safety/drain valve
fault (17 red flashes), heating of the interior is still possible.
