Beko Wmb 81421 M not spinning

After 5 good years my machine seems to have stopped spinning. It will fill a little with water, stop for 30-60 seconds, fill a little more, stop, no spin, then drain a little, then stop for a few minutes before the display shows it’s at the end of the cycle. I checked the pump, removed a euro coin and clothes tag from the fan, then verified it was free of other debris and could spin properly. Restarted the machine and had the same issue (although it seems to take on more water and drain more easily)

After reading several forums I took the motor off to check on the carbon brushes. I found a good amount of carbon dust, but the brushes seem ok: look to be at least 80% of original size, no burning on the holder, and the brushes are touching as far as I can tell. The only thing that seems a little off is that the contact area of the brush looks to be at 2 angles and not flat/round (hopefully the picture attached shows what I'm trying to describe).

I ran my finger across the commutator and didn’t find that any of the bars are raised. It’s my first time working on anything like this and I’m out of ideas and haven’t found any other ideas on the forum.

Unfortunately I didn’t check the error codes before taking the motor off, but will reassemble everything tonight and check for the codes (mine doesn’t have a digital display). Before going thru the ‘fun’ of reassembling the motor, does anyone have any other suggestions for what the issue could be? Is it worthwhile to get new carbon brushes to test? Thanks in advance for any help, the kids cloths are piling up and it’s only a matter of time before my wife’s patience runs out and we get a new machine. Cheers!
