BEKO WDR754 dryer not working

[Be Strong Discount Washers]

I have a Beko Washer Dryer 7 & 5kg the washer part works perfectly. The dryer however; door engages, pump engages, the washer begins to spin then stops and the door lock flashes and goes no further (it isn’t the child lock). I’ve changed the heater (dryer) I’ve changed the fascia board, I’ve changed both PCB boards and I’m at a total standstill. I would really appreciate it if you could give me another avenue to go down. Thanks

Hi there. It's unusual for a washer dryer to work perfectly okay on a wash cycle, but just not function at all on the dryer cycle. Faults that prevent even the most basic functions would normally affect the washing machine as a whole.

Unfortunately, any fault that I can think of that would explain why the dryer fails to operate at all would apply equally to the washing machine. If the washing machine functions perfectly okay, then it strongly implies there is nothing wrong would affect the dryer side. The only faults I've ever seen on the dryer side, are faults that just result in the laundry not getting tumble dried. Things like the heater (as the dryer has its own heater), the thermostats and cutouts, the fan. All of these faults would result in the drum revolving, and the drying cycle appearing to work, but the laundry just would not get dried.

So in my experience, I have never seen any fault that renders the drying section completely inoperable that wouldn't also cause a fault on the washing machine side. Obviously, you'd have to guess that maybe there is something wrong with the main PCB or control panel. That of course could account for it. But if you've replaced them and still have the same fault, then it remains a mystery. The only thing I can suggest is to doublecheck all of the connections and wiring to the control panel and PCB boards.
