my hotpoint wf840 washing machine will not turn on?

This sounds like a main module fault. You need to change the main module in the back of the machine. We stock it at £56.28 + £6 postage (exchange). This is ready programmed for your model number. To order, go to our website at www.emwelec.co.uk and WF840 in the search box or 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
