• Temperature thermostat defective.
• Heating elements defective.
• Safety thermostat tripped.
Heating cannot be adjusted
Possible causes:
• Temperature thermostat defective.

FAULT SIGNALLING

• Power failure
After an interruption in the power supply during execution of a
cycle, the control board signals the power failure by flashing
the PF icon. The cycle in progress re-starts from the beginning.
If a power failure occurs when the control board is on stand-by,
this will not be signalled and the control board will switch back
to stand-by.
• Safety thermostat
If the safety thermostat is tripped, an orange LED will flash and
heating will be deactivated. The services of a specialised tech-
nician are required to reset the thermostat.
• Oven chamber probe
If this probe malfunctions, the label AL1 will be displayed. Hea-
ting will be deactivated and the buzzer will sound intermittently
(three seconds of beeping followed by a ten second pause).
Pressing any key will silence the buzzer. The alarm will cease
when the condition is eliminated.
• Needle probe
If this probe malfunctions, the label AL2 will be displayed. The
regeneration/holding cycle is stopped, if it was a temperatu-
re controlled cycle. The buzzer will sound intermittently (three
seconds of beeping followed by a ten second pause). If the
current cycle is time controlled, no alarm signal is generated.
Pressing any key will silence the buzzer. The alarm will cease
when the condition is eliminated.
