I suggest you bring the pan with you to a very large Currys, or similar, where they have a lot of breadmakers on display by different manufacturers, and check which pan is identical to yours - then do a websearch for a replacement pan for that. Whilst I cannot promise this will yield a good result, I have a suspicion that the major parts of breadmakers from many different brands, come from a limited range used by all of those brands, since years, decades, even. If there is a risk in this method, it might be that minute differences in specification could lead to a part shearing off its non-stick coating into the bread mix. Or a part being underspecified for a new heat level (although surely breadmakers have always used heat...). But I don't know - and I think it's a route worth exploring a little bit, for anyone else reading this in the future, before chucking the machine.
