Adrian, it sounds like a main module fault (back of machine). We can supply one at ÂŁ59.88 + ÂŁ6 postage (exchange - ready programmed). If it does not sort the fault, then you can return it for as refund, less our handling charge of ÂŁ12. To order, go to our site at www.emwelec.co.uk and put WT940 in the search box. It will be a mk4 or mk6 (see the photos when you search on our site). Or you can call us on 0115 9652118 Tony EMW Electronics
