Hiya..
i have a wf840 and it starts washing for 8 mins into a quick 30 min wash then stops and erroe code F-08 comes up , ive found the fault codes and apparently this code means "Heater relay cannot be activated".
Any ideas whats wrong and how to fix it please

ok... ill answer my own question ....
i had F08 fault code but i guess its the same fix (ish ) for any fault code , but worth trying, all i did was remove the controll module which was very easy... and look at tracks on board, wipe it down and put it back..... pushing all connectors back firmly..... then switch it on and wash ... hey presto ------ NO FAULT CODES and clean clothes....

This is main module failure. We stock these at £49.90+vat plus postage of £5+vat. Go to our site at www.emwelec.co.uk and search for WF840
