Washing machine stopped working.
New brushes in the motor. Washing machine works but a bit noisy. After a few runs brushes bed in and noise goes.
All good for a few weeks but now getting an acrid sort of smell- what might be the problem. A little bit of arcing at the commutator/brush join but doesn’t look excessive.
What might be the problem?
I should add that they don’t seem to sell the exact ones for my machine anywhere but found some after market ones that seem the same dimensions. So poor quality brush perhaps?
Comm cleaner stick / bar and then clean comm and brushes with cotton bud and meths, alcohol etc? Make sure the gaps in the comm are clean with a knife blade.

Brush is a brush far as im aware. I replaced the ones on one of our industrial belt sanders with a pair that came with a cheapo diy wood router. I needed to sand the router ones down to the approximate shape to fit, but they worked fine and got the big sander up and running with no issues.
Ta. I used a tooth brush and some ipa to clean the comm, took a brush off and inspected it and I think it might be a bit bette for now.
I was thinking that re brushes but looking at the one I took off, the face doesn’t look totally uniform, as if the block of carbon isn’t a rectangular cross section and has a bit of a lump to it on the long side.
The exact spares can usually be found at ESpares (now owned by Screwfix), I’ve just repaired an obsolete Karcher pressure washer with genuine spares from them. Recommended.
Wof1 - thanks, tried there but seems only the £65 genuine ones are sold as fitting. Others might be identical but no way to tell without a trial and error approach as the model number doesn’t return a hit.
Re a brush is a brush. Poss not (but I’ve been wrong before), but I swapped brushes on my dryer blower, it worked fine and for quite a while, but when it eventually stopped working I found that the new non oem type brushes had worn right into the windings (originals didn’t do this), which I’m guessing was as the cheapo brush was much harder/less slippy…… - anyway new motor required.
DC motors will wear our carbon brushes over a period of time.
A clean of the commutator is a good idea as stated above before changing the brushes.
Try using a glass fibre brush to "clean the com", try below from Amazon as its cheap and will do the job.
After fitting the brushes, they will need to "bed in"
