I didn't realise that you should wipe the seal after use so that led to black mold. I got some of that cleaning and de calcifying stuff and did that on a very hot wash. All was fine and I've repeated every so often to keep things clean.
Last week I put a cleaner through and ever since the machine has had an awful smell - damp, musty as if a load of wet washing had been left in there. Before I put the cleaner in it was fine, apart from the black marks. I've tried leaving the door open but nothing works, my washing is beginning to smell AFTER a wash. Any ideas what it could be or how to solve it?
