My 80 year old MIL'S washer has a problem when trying to use the low or high speed spin only function. It just sits there revolving at a gentle pace & occasionally reversing. She tells me it is ok during a wash programme & spins properly, but I have not seen that for myself. Can anyone identify this fault or give clues where to start, or even if it is worth bothering looking at a 6 year old machine. Many thanks. PS a forum search did not bring up any relavant posts.
