Hey, this one is driving me mad so thought I’d ask for help!
I’ve got a Beko DCU6130W condenser drier, bought it cheaply in the hope it would be an easy repair. It was described as not heating, when I tried it at home it tripped my mains supply as soon as the power button was pressed
I examined the heater and couldnt see any issues and it seemed to have the right resistance when measured. But when it was disconnected, it no longer tripped the mains and the machine ran otherwise – so I purchased a heater element, swapped it over and still no heat.
This machine doesnt have a separate thermostat – there’s a trippable overheat stat on the top of the heater which isnt popped and has 0 ohms across it. There’s also a temperature sensor in the heating element and one in the airflow at the bottom of the machine, both have the right sort of resistance which changes when the sensor is warmed. I also checked the float switch by the water pump and that is functioning too.
So I pulled out the PCB, couldnt see any damage or dried joints. I didnt have a 12V supply available to test the relays so I just ordered replacements and swapped them all out. There’s 3 normal relays and one double throw – the heater seems to be connected to one of the normal ones. Put it all back together, machine runs, can hear relays click when it starts – still no heat! The only thing I havent swapped is the DT relay as the replacement hasnt arrived yet, but I dont think the heater is connected to that one. Cant find a circuit diagram for the PCB
Is there anything else I can do with this beyond a new PCB?
had similar machine to this doing the same thing a while ago
the problem originally was the temp sensor with a short blowing your trip.
on mine as with yours i replaced the element but no heat. upon inspecing the board i found a small resistor had blown. this is a surface mount resistor and is only about 4mm by 3. you need to look at the resistors under magnification and look for a burnt spot in the middle

Thanks! Will pull it back out and take another look. A resistor for a few pennies would be a great save 🙂
Gone over it with a fine toothcomb and cant see anything burned or damaged on it at all 🙁
Looks like I’ll need a new PCB – short of testing each component individually – but I cant even find anyone selling this particular part number so might have to throw in the towel with the machine generally
The only other thing I can see wrong is the lamp is flashing, I’m guessing the little PCB the lamp connects to has no bearing on the actual drying?
to make things harder there are 2 different board depending on serial
try looking again, the problem was with the ntc and this connect to the kn4 connector at contacts 5 and 6. Follow the tracks from these connectors and see if there is a resistor in series. if yes look very carefuly. it will look like a slight blemish and can be hard to see. you can also test with meter to confirm if its gone
