Product review (5 stars): Save money with do it yourself repair.  Fast and easy.
Repairman quoted $380 to fix dishwasher (start button no longer worked).  Read online about replacing this part.  It was delivered today and we replaced it in about 20 minutes.  Simply remove six screws at top of inside of door to remove old panel.  Handle assembly and electronic gizmo pieces both snap out of old panel.  Ribbon wire pills out of electronic gizmo.  Then do the opposite to install pieces into new panel and fasten with the six screws.  Turn power back on and the dishwasher works like a charm.  Compared to $380 to have repairman fix it or $500 to $1000 for a new dishwasher ... This was about the best $118 we ever spent.
