push start button nothing happens

Tried all of the above for my Whirlpool Quiet Partner I and nothing works. Unplugged it for a couple minutes reset the breakers did the 123123123 did the normal heated - normal heated tried holding the drain button for three seconds tried holding to start /resume button for three seconds. Nothing works. Cleaned out the drain but it wasn't plugged, had nothing in it. Any other suggestions that might work? It's only a couple years old.
