Possible action:
a. Check the temperature sensor (for open-circuit or short-circuit)
F32 Faulty temperature sensor in dryer The temperature (-B05) is <0 °C or >130 °C.
Possible action:
a. Check the temperature sensor (for open-circuit or short-circuit)
F33 Incorrect temperature in washing chamber Wash temperature (-B07) has not risen by at least 10 degrees C after eight
minutes’ washing.
Possible action for electrically heated machine:
a. Check that there is power on all phases up to the elements.
b. Check the overheat protection of the elements.
Possible action for steam heated machine:
a. Check the steam valve.
b. Check that the ball valve is open and that the filter in the incoming steam is clean.
c. Check steam pressure (see installation instructions).
