Hi,, I have a bosch WFO2466GB/07 that won't start. At first it would start if I banged it or jogged it, once the light was lit it would wash ok and restart as long as I didn't switch selector to off - then it wouldn't light again. Now it won't come on at all. I have taken the top off and checked the live feed to the selector switch. Am I right that I need a new switch, or do I need to replace the whole module/ front panel? Thanks, AlanT
