Beko Washing Machine tripping electrics after changing brushes.

[Northbeach]

Hi all,

Our washing machine stopped running through the programmes recently. It would turn on, run through the entirety of the programme time but the drum cycle would not kick in.
After a bit of research I figured it could be the carbon brushes which were low.
After taking them out at least one of them were almost worn to the base. Ordered some replacements and set about changing them. Once these were replaced I turned the machine back on and the machine tripped the circuits. Thought it could be carbon arcing within the motor (another recommendation) so a mate across the road used his air compressor to clean out any errant bits of carbon/dust. Before I replaced the motor I turned the machine back on and no shorting...motor (cleaned) back in and once again it shorted. I haven't tried placing the motor back in without the brushes attached but I'll do that some time today.

Aside from that is there anything that stands out here as a possible issue - any experiences of this anywhere?
There's only one way these brushes can sit on the motor due to lugs and screw holes and they're exactly the same ones as I took out.
Tearing my hair out moment again....it's not the greatest model of washing machines but it's only two years old and if I can fix this issue I'd be quite happy.

Many thanks.

What trips ,MCB ,RCD , RCBO ?

What trips ,MCB ,RCD , RCBO ?

the RCD. The kitchen is on a separate circuit to the rest of the downstairs.
It’s evidently quite sensitive as a build up of toast crumbs trips it occasionally.
I haven’t tried the machine on an extension lead to the rest of the mains btw

thanks.

RCD trips on earth leakage ( current escaping from a circuit), carbon dust being a distinct possibility. Re check the cleanliness of the motor ,terminals ,wiring etc. It doesn't take much leakage to trip RCD.
Compressed air can often contain water ,and moisture on electrics will also trip RCDS.

It was actually last week when we blasted with the air compressor so I’d expect any moisture to be dry by now. I’ll take the motor out again and clean the wires etc (there may be dust in the contacts that go onto the new brushes).
Any cleaning product recommendations? Nail polish remover?!

Also noticed the pipe from the tumble dryer has a rip which is sending out moisture round the back/under the sink area. Possibility moisture from there affecting the machine (though it’s not affecting anything else)?

many thanks.

Doubt the tumble drier has anything to do with it ,but obviously repair the hose.
At what point does RCD trip ,immediately the washing machine is turned on ,or at some point in the cycle ?

Check there isn't another fault by turning it on without the motor attached.

I recently had an issue with leakage from the heating element.

I only found out by disconnecting everything one by one. Would make sense its the motor given the work you have done to it, but prove it rather than assume.

Discard this I seen you have tested it all ready

Big apols folks....

Connected the washing machine up to the other mains via extension socket and straight away (as soon as it was turned on) it tripped.
Everything should be cleaner in the motor than it ever was. Bit of head scratching and a mate across the road had a look with me (he's a gas engineer so has far more insight into stuff like this than I). Turns out...wait for it...the connector (12/16 pin type?) from the PCB to the motor was inserted the wrong way round (and bear in mind I've been disconnecting this a few times when taking the motor out). I was convinced there was only one way for the connector to be inserted (all looked lined up and reversing didn't seem to fit without, so I thought, damaging the connector).
But there it is...inserted it the other way and hey presto - now works like a charm!!

Frustrated I missed that but slightly elated I've fixed it the machine for £10 (and with a bag of experience to boot!).

Thanks for all the replies.

Ya numpty !!! Good result mate

Haha - I wasn't expecting anything less!
Kicking myself as I usually photograph everything I take out. Presumed this was a dead cert one way insertion!!!

Thanks mate.

That is really unusual, appliance pl/skts usually have locating pegs of some description. Perhaps the bad press about Beko appliances is justified.

I think they probably did tbf...what probably happened is I tried to fit it one way and it didn't fit (hence that being noted as incorrect) then the other way slotted in...which turned out to be the incorrect way. Was fiddly tbf but entirely my fault.
