Fault messages
The electronic circuit boards constantly check on their own status. If any problems with the hardware or
defections of the circuit board occur which could have a negative effect on the safety of the end user,
the appliance will switch to a “safe” status in which the electric valves are switched off. The code for the
type of error appears in the display.
It is only possible to reset the electronic system by disconnecting the power supply for at least 30 minutes
or by turning the mains plug by 180 degrees. If this does not delete the error message, the electronic
unit will have to be replaced.
