My washer dryer (Indesit WD12X) starts ok but half way through the wash the program selector starts to click as it keeps turning round and round automatically without stopping. What could be causing this? An engineer came round yesterday and said it was the heating element. He said he would get a price for a replacement and let me know today. He took the old element with him. He has just sent a message saying it would cost £75.73 to get the new heating element and install it. I'm surprised the heating element would have caused this and suspicious that he's puling a fast one. Any opinions?
