Can you post the E-Nr number of the appliance please?
OK, thanks for that.
does the drum turn normally during the wash?
If it does, what exactly happens during the spin?
If you set it to spin now, what happens?
Do you get any flashing lights or error codes?
Do you mean the drum doesn't turn?
If this is the case, you need to check it on a rinse, see if the drum turns.
Unplug the appliance.
Take the rear panel off.
Check the wiring and the plug to the motor.
If ok, unplug the motor.
Take the motor out of the appliance and check the carbon brushes.
If worn out or broken, replace them.
Refit the motor.
Reassemble the appliance.
Try it again.
Check the carbons, let me know what you find.
If the carbons are ok, it's likely the motor and/or control board will be at fault.
This would be an expensive repair.
Let me know if the carbons are ok.
Hope this is of some help
Let me know how it goes or if you need more help
