Ok my tumble dryer is seriously ill. It is a 2 and a half year old hoover condenser. when i turn it on it is heating up but is not spinning. If i turn the drum then it starts spinning but then when it needs to change direction it stops again and you need to turn the drum again. It still works but just doesn't spin. what do you think is wrong with it? how much do repairs usually cost for this sort of thing? any comments are welcome.
