Beko WMB714422B Washing Machine Keeps On Blowing The Fuse

September 23, 2024

Last week my Beko WMB714422B washing machine was running and I heard a loud pop. I had a look at the machine and the motor's brushes, one was broken and the other was fine, a longer length. So, I replaced the brushes and then realized that the PCB board that supplies power to the motor had two tracks blown on there. So, purchased a new one. Today i fitted the PCB and ran the machine... It blew the fuse again. I pulled out the motor to examine the brushes again. On my motor housing where the brushes sit there are two position options for the brush to sit. I placed the brushes so that the flat side of the brushes are touching the contacts and not where the tip touches the contacts on the motor. I would really appreciate any further assistance n how to get the washing machine running .... dirty clothes are pilling up and wifey is not happy, so any help most appreciated. Thank you

I will try and help with this problem about Beko WMB714422B Washing Machine,

Hi Paul,

Thanks very much for the information on your Beko WMB714422. I hope you haven't damaged the new circuit board, as there might still be a problem with the motor. If the carbon brushes are sparking when the motor turns, it means they are not making good contact with the armature. Raised lugs on the armature could be causing this issue.

You should have the motor tested independently to ensure it is working correctly and not causing any direct shorts or problems, as it is supplied by the PCB. If the motor isn't working properly, it could damage the new circuit board, so please keep that in mind.

I have included a video below that shows how I test circuit boards and motors. It’s worth watching to learn how to bench test a washing machine motor, though I don’t have the exact wiring configuration for your machine. I found the wiring diagram, workshop manual, and some test procedures for you.

Please get the motor tested properly because any problems with it will cause major issues with the circuit board again. It might even be worth investing in a new motor if this seems to be the problem.

I hope all this information helps you repair your machine.

All the best,
Paul
