Beko WM5100W keeps draining

[SteveSixx]

Hi. The drainage pump on my Beko WM5100W washing machine recently burnt out (the spun copper parts on it seemed burnt black, and it smelled of burning plastic), so I replaced it with a new one of the same model, and now the machine fills and drains at the same time, accomplishing nothing. The pump can be heard pumping the water out so I don’t think it’s a drainage hose height problem (also the drainage hose is raised higher than the machine, going into the kitchen sink at the moment) and the sound of the pump doesn’t stop for at least a few minutes. Eventually after a few minutes, the machine will stop taking in water and pumping it out, and the pause light on the front will flash repeatedly.

I can successfully wash clothes by first unplugging the power cable to the new drainage pump inside the machine. Starting a wash cycle with the pump unplugged will wash the clothes just fine, but obviously they won’t spin and drain after because the machine is still full of water. I then plug the pump back into the electricity and put the clothes on a ‘spin and drain’, which works just fine.

I replaced the thermostat because I read somewhere that a faulty thermostat can cause a washing machine to think the water is too hot, and thus drain it out. I tested the old thermostat on a multimeter before I ordered the new one, and was getting nothing out of it set on 200 (I watched an eSpares video that said the multimeter needed to be set on the lowest, here https://www.youtube.com/watch?v=bJZpgbMvM6Q), so I ordered the new one, however, upon further tests after ordering, I found that if I set the multimeter to 20k I get a reading of 4.75, which starts to go down if I warm the thermostat up with my hand. The new thermostat does exactly the same thing, so I’m guessing it wasn’t the problem.

I’ve tested the pressure switch on the multimeter too. The pressure switch has 4 connectors – the usual 3 at the bottom, and an extra one in the center. The middle connector and the left connector make a tone on the multimeter when no pressure is applied, and the tone stops when pressure is applied. The middle and right connector make a tone when I blow into the pressure tube, and there is no tone without pressure. The 4th connector however seems to do absolutely nothing at all, and I can’t seem to find any information on it. Here is the switch – http://shop.ukwhitegoods.co.uk/beko-was … ure-switch

I’ve also blown down the tube into the machine, the air gets through and I can hear bubbles, so I’m guessing it isn’t blocked.

Any help would be greatly appreciated, thanks.

Re: Beko WM5100W keeps draining

unfortunately when the pump has blow it has also blown the electronic switch on the control board called a triac. to fix the machine this will have to be replaced or the whole programmer will have to be changed
you can change the triac if you can solder pcb components but there is a possibility other components on the board may have been damaged as well

Thanks for the reply, I was afraid it might be the control board. I’ll probably just end up replacing the machine in that case.

Thanks
