Twice now this week our lass has said that when she comes to tumble dry something in machine the machine starts to fill with water... I looked at it and sure enough when I put it to tumble setting it started to fill, then I spun it out and tried again, this time it was ok.... and have dried other stuff after and no probs, then this morning she say's Oh forgot to tell you last night the machine is filling when on tumble again.....WTH!!!! I go and try it this morning and all ok, does anyone have a clue what either is going on or....something that she is doing/not doing (she has been using this machine for 2 yrs with no probs)....
