AEG Washer/Dryer stops part way through drying cycle, no error code
Hi everyone, looking for some tips with a mysterious failure in the drying cycle. Many thanks!
AEG washer/dryer Kombi, 7000 DualSense, model L7WEG841R. Bought new in mid 2021.
Washes fine but drying cycle gives up a few minutes after starting - as soon as the sound of air blowing begins, the time countdown skips down to 10 minutes, and it wraps up the cycle. I think no heat has reached the clothes. No error codes at any point.
Detail of an example problematic drying cycle, set for 1:06 hr drying time:
- Counting down from 1:06 to 0:56, does stuff more like a slow spin in the washing cycle.
- At 0:56 starts blowing air like the dryer usually does.
- The Problem: 30 secs later timer skips down to 0:11.
- Continues blowing while counting down. Reaches 0. Beeps a few times. Stays locked almost 10 mins with occasional small drum movements, then unlocks. Didn't feel like any heat had reached in.

I was able to get the machine to tell me an error code by holding down two of the control buttons. E73. whitegoods indicates that's about the NTC sensor:
- Fault in NTC sensor on drying duct (voltage out of range = short-circuit, open circuit)
- Drying NTC sensor (duct) faulty
- Wiring faulty
I think that's the "temperature probe" part 470 on the dryer parts diagram.

Not an answer, just a placeholder for the image of a controller part
Is this a good question?

Just to say, I am getting exactly the symptoms you describe on a L8WEC166R. Interested how you managed to generate a fault code, but I am guessing this may be with some diagjostics equipment. I was also confused why it affected timed cycle as well, but came to the conclusion that it may still be using the moisture sensor to prevent overdrying. My next step was going to be replacing the moisture sensor but struggling with time to take it apart at the moment. As you say, if that is not the problem, then a controller issue would be the next thought. But in my limited experience of controller faults, these generate much more unpredictable symptoms which is why I am not considering this as the likely culprit for now. Also it is expensive as you say.
Did you advance on diagnosing and fixing the fault here? Would be helpful if you have further updates.

Hi Herman, the fault code wasn't hard to get, using a "hidden" button combination. I think I got it from https://www.youtube.com/shorts/ILVoCO1M_... .
I'm just getting back to trying to fix this, been using a dehumidifier and drying rack, which works surprisingly well. And if I mess up and knock out the washer as well, that would be a proper domestic disaster. Will update as soon as I have something.
