What could it be? I'm very worried that if anything wrong, this could cause short curcuit of the house electrics (I'm by myself atm and don't fancy going into cellar where switches are to fix that).
And secondly, worried that the machine is breaking down. It's oldish but been working absolutely fine so far, I use it twice average max, am away sometimes so it's not overused.
I also thought could it come from extractor fan in the utility room. Once the washing stopped it was quite strong for a bit then gone completely.
How to check safely if machine can be used again!?
