Asko W90 (aka 10504) only spins

[henrym]

We have an Asko 10504 (aka WM90) washing machine.

When it last ran, it was set to run on a normal wash cycle. When we returned to it, it had stopped. However the door would not release. On opening with the manual release, the drum was still filled with water. I tried to restart the wash; in ALL active positions, the drum spins (at spin speed), the programme control knob drives clockwise until an end of wash position is reached and then it stops. In wash 9 (position to interrupt programme), the machine should just pump out, without any drum movement; instead, the drum spins, and no water is pumped out.

Further checks:
The pump is clear of debris; it runs if powered directly. If the main motor is disconnected, the pump runs in wash 9 (and the timer advances to stop after a minute).
The main motor circuits show resistances of 2, 3 and 15 ohms (field, armature and tacho), with no cross-link.
The heater is not open circuit and there is no earth leak (here or elsewhere). The pressure switch clicks on testing, the supply tube is clear.
There are no signs of burning on the timer PCB.

What is the likely cause of the problem? Faulty timer, main motor or something else? Can they be checked and replacements obtained?

Thanks for your help in advance

dont know this machine but
from what you describe it sounds like the motor is going into spin speed and the machine detects the fault and shuts down

could be

1 motor short to earth
2 motor tacho magnet loose or broken also poss tacho coils open circuit
3 main printed circuit board triac short circuit

you may need the help of a professional

if you put in on at the start and it goes straight onto spin more likely the timer could be motor but more likely timer fault.they were bad for maybe washing for 5 mins then the timer just clicked round to off position and stopped full off water.
