Beko wm74135w smoking motor after changing brushes

Recommended Posts

Hello I have a Beko wm74135w that recently would not enter its final spin. It would spin fine up until the final spin though. I checked the brushes and one was worn completely down. The other maybe only 30% worn. I had only changed them about a year ago so.

I ordered some new brushes but they were for a different Beko model. They are angled the correct way though so I put the new brushes in to the original brush casing and fitted them. All was fine and it was fast spinning except it seemed to spin faster than usual (can't confirm is this true or not since I am not the one that usually uses the machine). Next it started smoking from the back (I presume motor) So I switched it off.

I checked the brushes to make sure that they were fitted correctly and they seemed to fit flush but there does appear to be some burnt marks on the brushes. Now the motor will not work at all. I have entered Test mode and the first thing that comes up on the screen is "E--". I presume that this means that there are no errors. The next thing that comes up is "052".

Could the brushes have burnt out the motor?

Could this be a problem somewhere else in the machine?

What does "052" actually mean?

 

Thanks

Hello. The brush in the first picture doesn’t look like it’s at the right angle. It’s imperative to fit the right brushes.  It doesn’t look like the whole of the surface is touching the commutator. That would cause a lot of sparking. If you can smell a very pungent smell that lingers, the armature may have burnt out.

If the whole of the surface of the brush isn’t contacting the commutator then sparks start leaping between the brush and commutator. If the motor stopped working it could potentially just be because one of the brushes stopped making contact altogether. But it could also be because the TOC in the motor blew, or even potentially something in the PCB got damaged. Not a good situation  buying a new motor would be an expensive gamble.

Also if you only replaced the brushes a year ago and one of them has worn down already I would suspect that the brushes you were supplied were not genuine ones. It's very common for appliance parts to be copies of the originals and sometimes they are definitely not the same quality. My personal experience has been that carbon brushes are one of the parts where you really should always fit the genuine ones. The non-genuine ones are a lot cheaper, but tend to be much softer. They can wear out much more quickly and can cause a destructive buildup of carbon dust inside the motor.

I see.  We have decided to get new a washer with a 10 year guarantee on parts which hopefully includes brushes but I'm guessing they are classed as disposable. Its not really worth repairing this Beko machine. Thanks for the information, it will come in handy for the future. Great website you have here, I will recommend it where possible. Also we will buy a new machine through one of your affiliates if they have the one we want.

Thanks

Many thanks. Yes the long guarantees only cover manufacturing faults and never any part that has worn through use. I think you made the right decision not to attempt fitting a new motor.
