Possible Causes
This is caused by a heater
malfunction:
•
Check air heater wire
harness for loose
contacts.
•
Check that the
heater element is not
interrupted.
•
Check I/O PCB air
heater relay output.
•
Defective PCB and/or
software failure
•
Replace Color LCD
controller.
Electronics – motor driver
failure (I/O board)
•
Check Dryer motor
wiring.
•
Verify that motor stops
when in non drying
phase.
•
Replace I/O board.
•
Replace dryer motor.
The temperature sensor out
of range:
•
Check temperature
sensor wires for loose
contacts.
•
Run cycle to monitor
that the water
temperature is below
96°C.
•
Replace sensor and
verify if the CF persist.
•
Replace I/O PCB.
The water reservoir overflow
switch was triggered:
•
Check the water
reservoir full switch.
