hello, right, this is going to be difficult to explain, but i have just finished washing a load of white sheets, took them out and there is filthy black/grey gunk all over it. looks like it has come from the inside rubber seal from the door, i had a look and the inside rubber bit is covered in black/grey gunk, i've tried to clean as much out as possible, but its horrible...
this hasn't happened before with my washes,
any ideas what to do???
thanks so much
