short circuit
- Check efficiency of contacts on connector
J011
(commutator) or
J14
(three-phase) on PCB;
- Check NTC impedance value on wiring connectors
J011
(commutator) or
J14
(three-phase) between pin 1 and pin 2.
The impedance value at ambient temperature (20°C) must be
approximately 20 KOhm;
- If measurement is incorrect check NTC wiring;
- Check the same parameter directly on the NTC (20 KOhm);
- Renew NTC;
- Renew PCB.

- Check efficiency of contacts on connector
J012
(commutator) or
J13
(three-phase) on PCB;
- Check continuity of the dryer heating element on pins 1 and 2 of
connector
J012
(commutator) or
J13
(three-phase) ensuring that
the value for the 1500W 230V heating element is approximately
36 Ohm;
- Check leakage between the two ends and ground, impedance
should be at least 2 MOhm;
- Renew dryer heating element;
- Renew PCB.

- Disconnect appliance for 2 minutes. Check that correct
operation;
- has been restored by starting the Autotest routine;
If fault reappears renew main PCB.
