My Kitchenaid dishwasher model KUDIO1ILBL6 periodically quits working and the Normal button blinks...sometimes with the Cancel button blinking and sometimes not. Had a repairman out and he just ran the diagnostics cycle and it started working and he told us to run the hot water tap before running the dishwasher. We do that every time now, but it still occasionally quits and I run the diagnostics cycle and it starts again. That is until this time. I turn off the power to the dishwasher to stop the flashing and as soon as I touch the High Temp button the first time...it starts the Normal button flashing and after keying the complete sequence...nothing happens. What am I missing? Thanks!
