7.3.1.4 Fault messages
If a fault message is present, this flashes in the display. If several fault messages are present, all of
the fault messages are displayed in turn.
Display Text display (description) Possible cause
F.00 Interruption: Flow sensor (NTC)
NTC defective,
NTC cable defective,
Defective plug connection on NTC,
Defective plug connection on electronics
