>There's a fairly good chance that the circuit board has a conformal coating - a very thin layer of waterproof lacquer protecting the entire board
Makes sense, I'll take the risk and leave it as-is. I can't see any lacquer, the top of the chip looks matte, whereas I'd expect it to look shiny if there was a lacquer layer on top, but honestly I'm not sure I'd know it if I saw it - attached an image of the chip anyway, but it's not great quality.
>I'd suggest getting your washing machine repaired
Sounds advice, I just can't afford to get a plumber out, or a new washing machine. I don't think it's the washing machine that's at fault - I've watched it flushing at the end of a washing cycle and it's not any faster than a tap, it's just that the back pressure on the pipe makes it spit back up and out (I've run a few packs of descaler through the machine anyway and will be doing so regularly from now on, I guess). The whole place has problems with plumbing, I have to pour drain cleaner down both sinks and the bath every month or water starts backing up, and I'm not flushing coffee grinds etc down there, so I don't think I'm doing anything especially dumb to cause it. I've checked the accessible piping for blocks and there's nothing present. I do have a housemate but he's aware of the issues and has been told the do's and dont's so I doubt he's doing anything much to cause these problems.
Thanks for your advice, anyway - any further input appreciated, obviously I'm not an expert in any of this stuff.
