Sounds like a main module fault (in the back of the machine). We stock it at £65.88 inc vat & postage (exchange). The module is ready programmed and if it does not sort the problem, you can return it for a refund, less our handling charge of £10.80. To order, call us on 0115 9652118 or order online at www.emwelec.co.uk (put your model number in the search box at our website). Tony EMW Electronics
