and there is some sort of black slime [boak] in the deep, "crack" bit.
Its a fairly new machine and I've never had it happen with my previous machine. I guess I need to leave the door open wider when its not in use which is going to be a pain as its in a very narrow utility room. But what do I clean it with to get rid of the slme, have tried hot water and its not worked, I don't want to use anything that may perish the rubber.
Thanks.
