Beko WMA510 No spin amongst other things

Called out to this one last night, the customer had complained that the machine doesn’t drain and spin sometimes, and that earlier in the week it took seven and a half hours to complete a wash cycle 😕

I ran a spin program which started and picked up into a spin no problem.

I checked water pump for blockages etc nothing there, checked carbons on the motor they were approx 2/3 worn but still plenty of length on them.

I ran the machine on a rinse and spin, the machine filled turned once then didn’t do anything else, I gave it a couple of minutes but then cancelled the program and selected spin. This time the machine began pumping but stopped after about 30 seconds, with no drum action at all.

I had assumed that the board must be faulty because of the random nature of faults, but on reflection I am wondering about the brushes.

I have in the past had a fault on a Beko where the machine starts and cuts out after about 20 seconds due to the carbons being worn out.

Any thoughts?
