Servis Grande problem

[chmielar]

Hi,

I have a problem with Servis Grande washing machine. We’ve overloaded it with the towels this morning and eventually it stopped spinning the drum.

So far have done the following:

* took the motor out and it seems to be OK (no sign of burned windings)
* checked the brushes by measuring the resistance across the windings while spinning the shaft and it changes so assume they’re OK
* checked 6.2 KOhm resistors on 546020701 board and they seem to be OK
* visually checked triac but no sign of damage
* tried the machine on different programs it takes the water and pumps it out but no drum motion.

Can anybody advice what could be the reason. I’m tempted to replace the module but it’s about £45 so I want to make sure it is absolutely necessary.

I don’t know much about the washing machines so any help and advice will be much appreciated.

Regards,
chmielar

Model number would be a good start…….. M—-

The electronics are always the weak spot with Servis appliances, the pcb will fall over if you smile at it incorrectly. Assuming that you have continuity through the motor when measured through the loom at the pcb end, there isn’t anything else to fail. I take it that there is no drum action at all?

Penguin45,

Thanks for your response.

The model number is M3810. I’m not entirely sure how to check the motor the at pcb. Can you advice what pins to measure across.

Just to confirm, there is no drum action at all but the rest (pumping, heating) seem to be fine.
