My bosch diswasher won't start. The on/off LED light is on and the timer control cycles about halfway through the wash cycle and stops when the soap dispenser is tripped. Nothing happens after this. A couple of days ago I had the same problem but after switching the on/off and program buttons many times it magically started. I thought it might be a bad switch but after removing the front panel the switches all seem ok (they are all mechanical and seem to be making good contact. Does anyone have a suggestion? This dishwasher has been trouble free until now. Thanks
