how can I fix my Indesit IWC6125S?

Ian, sounds like you need to change the main module in the back of the machine. We stock it at £53.88 + £6 postage (exchange). This is ready programmed for your model number. To order, get the info listed at http://www.mawdesign.com/tech/info.jpg & then call us on 01159652118. You will still have the option of returning the module within 14 days for a refund (less our handling of £12) if it does not sort out the problem. Tony EMW Electronics
