Kenmore elite dishwasher is not starting. Beeps 15 times initially when opened or closed and once this stops, it flashes complete 4 times. I tried to reset it by going back and forth with the normal wash and high temp as I had read but that did nothing. Have unplugged it and plugged it back in but nothing again.
Unit is between 4-5 years old and we've had numerous issues with it. Two of the lights on the control panel have been lit and dim and go off an on at any given time. We've also had service calls twice to fix a cheap clip on the drain pipe I believe.
Not sure if we should just throw in the towel and move on. Any help is appreciated.
