Beko DCU9330W

[BorisTheBlade]

Hi,

I have a Beko DCU9330W tumble
Dryer that’s not warming up. The heating element and cutout thermostat are ok. There is a second cutout sensor that looks like the heater cutout thermostat but it maybe a thermistor or other temp sensor because I’m reading 185 ohms across it and the wiring from the sensor to the pcb is very small so not carrying any real current.

The pcb relays don’t appear to be switching out 230vac for the heaters but I’m not sure if this is because the relay / pcb is Duff or it’s not receiving the right signals from either the suspect temp sensor or another item in the tumble dryer? Any ideas? Cheers.

Re: Beko DCU9330W

is your reading of the other sensor with the wires off or on ?

Wires off.

Re: Beko DCU9330W

chances are its faulty should not be that low

change the element

Re: Beko DCU9330W

Hi Dave,

Do you mean change the entire element arrangement? I.e element and two thermostats?

The element is ok and I guess you cannot buy the sensor seperatly?

Thank for the assistance.

Re: Beko DCU9330W

have had a few do this its not unusual. normally i put a spare thermistor in just to check diagnosis but the correct on is riveted to the boared so cant be changed

element part no 2970101500

Re: Beko DCU9330W

Ok great thanks Dave.

It seems logical (captain?!?) the pcb doesn’t turn the heater on if it cannot determine the temp. All the tumble dryer problems I’ve seen in the past have been based around replacing the two thermostats but this is the first time I’ve seen a temp sensor.

You don’t know of a thermistor part # I can use as a double check do you?

Re: Beko DCU9330W

i use one of a hotpoint heater from a washing machine. just plug the wires onto it, leave it hanging somewhere it cant catch and rum the unitb with the element cover off for 10 secs or so. if i get heat i know i am right ( but make sure no one can get hurt by the fan turning with no cover on )

heater on thermistor is off an old hotpoint wm series unit ( like WM62p)

chances are if you have a local repair shop they may have an old one knocking around as you get a new one every time you renew the heater

Thanks Dave. I’ll post back later.

Re: Beko DCU9330W

Hi Dave,

Good news. I figured it would be a 10k or 100k thermistor so I joined a bunch of 1k resistors together and connected them in place of the sensor. En Voila, the heater turned on.

The actual sensor is not riveted but held in place via a couple of folded over tags. Is it possible to replace this with a Beko thermistor from another model that is replaceable or would that be risky?

Cheers

Re: Beko DCU9330W

cant comment in a way but the overheat stat is there in case of serious temp rises

you would have to find on of another tumble dryer where the element had failed. Beko dont supply it on its own
