Hi, I have a Siemens SE64630GB/12 dishwasher. Recently it has started up OK filled with water heated and washed but then stops full of water and with all lights off on the switches. If I wait long enough sometimes it resets and contiues the cycle. Could this be a faulty thermostat or controller. I have stripped and cleaned all pipes, flood switch and check the float switches operate OK. I have checked the on/off switch and inspected the wiring and controller connections. Where do i go next, perhaps the tip!
