Why is my AEG washing machine tripping my fuse box?

Hi. Just thought I'd give a final update in case anyone else comes across this thread with the same issue.

Before I contacted an electrician I tried one last thing. As I mentioned, the washing machine only seemed to trip the electrics when it had a load in it but not if it was empty. Initially, I thought that it might be the weight shifting the drum or putting extra stress on the motor. However, I had also noticed that there was a wire going into the back of the drum about a third of the way up from the bottom. I assumed that this might be a sensor of some kind and that the higher water level was affecting it. I had nothing to lose so I unplugged it and started another wash cycle whilst keeping an eye on it. This time it worked without any problem. So I decided to take the risk and buy a replacement for this component. It turns out that it was the humidity sensor. The replacement cost £30. When I received it I swapped out the old one. I couldn't see anything wrong with the old one. It's literally just two small wires attached to a plug on one end and a sealed plastic probe on the other.

I was still slightly worried that the fault may lie further down the connection and that by disconnecting the sensor I had just stopped the current from reaching it. However, I have now completed a few full washes with the new sensor and have had no issues.

So there we go. I have no idea how or why that sensor caused such a major issue.

Even though I also bought a new heating element that proved redundant, in the long run, I think I saved money by not having to call out someone to repair it. It was an interesting challenge to work out if nothing else.

I am going through same issue as you. Your post is helping me a a lot. Thank you

My AEG 7000 kombi was tripping the RCD part way through cycle. Drain and spin were fine. I swapped out the element. Still tripped RCD. Read this thread, swapped out the humidity sensor £17 plus shipping. It's run 2 loads with no issue so far!! Cheers

Those that have replaced the humidity sensor, were your machines tripping the RCD on wash only cycles without drying?
I almost never use drying function and a normal light load 30c wash is tripping out during the heating washing part of the cycle.
New element hasn’t fixed it hence looking here.
Would the humidity sensor affect the wash only cycle?

Humidity sensor is for the drier only, but that doesn't necessarily mean that the electrinics won't get upset about a faulty one at other times.
Your problem is likely to be a faulty water heating element.

I tested my original one and the sensor with my meter and was fine but replaced it anyway already and machine still trips.

I’ve now unplugged the humidity sensor and running a wash only cycle to test it.

Ran 3x wash only cycles through it now without tripping just by disconnecting that humidity sensor!
Thanks to those that discovered the fix!
