29. Door and safety locking device

Fault location

Door does not unlock

Conditions: wash program ended and drum at a standstill

Measure the voltage between the following points:

1. X93:2 - X93:3 Should be 0 V DC. If the voltage is 220 V AC, check the rotation

guard.

2. X193:1 - X193:2 Should be 0 V DC. If the voltage is 220 V AC, check the rotation

guard and the cables between rotation guard and delay unit.

3. X194:1 - X194:4 Should be 220 V AC. If not, the ”open” signal from the

programmer circuit board is absent. Check pcb and cables between pcb and delay

unit.

If the door is still locked, replace the delay unit.

Door does not lock

Conditions: door closed and wash program activated.

Measure the voltage between the following points:

1. X194:1 - X194:4 Should be 0 V AC. If the voltage is 220 V AC, the programmer

circuit board will constantly send the ”open” signal. Check pcb and cables

between pcb and delay unit.

2. X194:2 - X194:3 Should be 200 V DC.

- If there is no voltage, replace the delay unit.

- If this voltage is present, check the door lock coil and its cables.
