Thanks again for the advice Dave,
The draining speed seems ok, and I’m now pretty sure the problem lies with the control board. It’s taken to missing out whole sections, so a 3.5 hour cycle is taking 1.5 hours.
I’d like to replace it, but the best price I’ve seen for a board is £170, plus about the same for a drum unit (apparently you can’t replace the bearing on it’s own!) so I think it is new machine time.
I’m thinking of one of the Samsung smart washers. Have you had any experience of them?
Cheers
Dave
