Dishwasher is about 5 years old and used sparingly as it is in a vacation home. This year it has shown starting problems. Lights work but cycles to not start. I tried the 'realigning' door latch tip where you make sure installation was level. Thought it worked but problem is back. WHY does turning the breaker off then back on work??? Is there a "reset" that can be done using the keypad? Because the unit has long stretches of not being used could there be a corrosion problem with the push buttons? After a breaker box reboot things are better for awhile then problem returns? Suggestions??? Thank you.
