carbon brushes, I get that bit (and btw, black dust in the back of the machine, could this be from the brushes or is it from belt wear?)
Faulty valve? Is that an inlet valve or other?
Cheers.
Scrap that, it’s sorted.
For the record I think it went out of sync somehow.
I manually filled the ice tray.
It tipped it into the bucket then filled itself with water.
Bingo.
