AEG washer/dryer tiny leak from humidity sensor
AEG L7WEG851R washer/dryer. This is about the third issue I've posted about for this machine; it hasn't served us well!
I have checked advice articles and can't find anything about this specific issue.
Background
We discovered recently that the water was not actually getting hot, so I got busy with my multimeter and established that the heating element had no continuity. I've fitted a new one today and it's working - the water is hot.
However during my testing I also removed what I think must be the humidity sensor, presumably for when it's drying. It goes into the back of the drum and has a probe on the end. Please correct me if this assumption is wrong. I've attached a couple of photos to show the part I mean.
Issue
When trying to reinstall the sensor, it doesn't feel like it's going in as far as it should. There is a rubber grommet around it with a little flange, which feels like it should locate into the hole in the back of the drum. However it doesn't go in very far, and the grommet seems like it's way too big to go in there.
Since replacing the element, I've run the machine and all seemed well. However I took the cover off the back again to check all was dry inside, and there was a bit of water in the void just below the humidity sensor.
I'm guessing this can't be right, but I also can't see how the sensor can go in any further.
Any advice on what I should do?
Photos - one shows the location of the sensor on the back of the drum. The second shows it closer up, with an arrow where I found water had collected.

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
AEG L7WEG851R washer/dryer small leak at rear sensor/grommet after refitting
- The problem
- After replacing a failed heating element on an AEG L7WEG851R washer/dryer, the owner refitted a rear drum sensor/probe with a rubber grommet and then found a small amount of water collecting in the void below that area. The sensor did not seem to seat fully back into the hole.
- Likely cause
- Most strongly supported diagnosis is a minor leak past the sensor/grommet seal after refitting. The exact identity of the part was not confirmed in the discussion.
- What fixed it
- Suggested remedy was to refit and seal the sensor/grommet using a suitable flexible washing machine sealant, with Debor named as a commonly used product. The discussion does not confirm that this repair was carried out or that it stopped the leak.
- Checks to try
- Heating element tested with a multimeter and found to have no continuity
- New heating element fitted and heating confirmed to be working
- Rear cover removed after testing and a small amount of water was found below the sensor area
- Owner checked the black rubber tube and confirmed it runs to a connector block
- Parts or tools mentioned
- Heating element
- Multimeter
- Suitable flexible sealant
- Debor sealant

Where does that black rubber tube go to at the other end?

Thanks for replying.
It goes to a connector block, which has a connector plugged into it. It's actually visible in the close-up photo, in the bottom right of the picture with blue wires coming out of it (but it's hard to see because it's in the dark).
Maybe it just needs fitting back with some washing machine sealant?

I did not know that was a thing. It's such a tiny amount I think that would do it. Thanks for the advice!
You can use any suitable (flexable) sealant but the one most washing machine repairers use is called Debor
