Hello dear Community,

My AIO is working since couple of weeks, but now started to give some (scary) noise - maybe it was already there, but we heard it couple of days before.
The noise disappears, if I
- I switch of AC or
- I switch off DC or,
- AIO itself

I made a video, but I only can attach a photo :)
The noise is like a water heater is overheating, like a which is laughing and flying through the city:)

It seems that is coming from the back of AIO top right.

Do you have any idea?
I will try with the german customer care as well…

Thanks,
Zsolt
