Re: Beko WM74165W – Turns off once it fills with water

So It works fine from start to finish on a cold wash but if you put a wash with any temperature it fills to the bottom of the door and then its lights out. Still think it has to do with the heating circuit.

I took apart the display to test components on the PCB last night and I found three diodes working correctly (allowing current one direct but not in the other) and three not working correctly (allowing current in both directions) testing with a multimeter.

I’ve ordered replacements and will replace these by the end of the week, hopefully this is the problem! I’ll update again then.

Electronics isn’t my strong point so if anyone out there has any wisdom please reply

Re: Beko wmb91442L

How do you diagnose a controller fault? I have a similar problem with a beko, turns on and fill up then complete electricity loss at the point it should start to turn the drum and heat the water. Works ok on a cold wash though, changed the element but that hasn’t made any difference so now I’m thinking the control board.

Any help would be very much appreciated!

Got a new element today and fitted, but the same thing is happening?
There is bound to be someone who could shed some light on this for me??

Running a wash with the water temperature cold works fine, this must mean the problem is when the machine tried to start heating the water??

I’ve checked for resistance across the terminals of the plug. No circuit between the live and earth. Fairly high resistance between live and neutral, this suggests there is no short in the machine, right? I was thinking there could be a short in the heating element.

When I check the resistance across the element it’s self I get a reading of 28 ohms, I’m fairly sure this is as it should be. I also get no circuit between live and earth again as it should be!

Could it still be the element???

Re: Beko WM74165W – Turns off once it fills with water

I haven’t had any replies and after scouring the internet I cant find too many repair postings for my model so I can only assume not to many people have had problems to date.

I’ll keep updating in the hope I figure it out and it might help someone else.
So I’ve been having a look about my machine today, took the back panel off and tested the heating element with a multimeter hoping it was the heating element causing the machine to cut power on the 011 cycle. I’ve found a page on the internet that suggest this is the stage at which it will run a complete wash test in power mode.

As I mentioned before at 010 the machine goes straight onto 011 after a split second, again I think from what I have read 010 doesn’t do anything anyway and it may just bypass this normally – maybe someone can tell me different??

After connecting and disconnecting a few things once I get to 011 on the display the machine now fills up with water to a certain level and then the power to the machine cuts out. Maybe there is a water level sensor that has failed? something else at this stage may be supposed to kick in and isn’t causing the machine to knock out of power?

I’m still trying to test things but I’m not much further on. If I figure out more I’ll update the post. Hopefully in the mean time someone more knowledgeable will be able to point me in the right direction.
