Dishwasher leaked under right front corner. Discovered that overflow(float switch) was either sticking allowing fill to overflow or rubber gasket was deteriorated allowing water to leak through mounting hole.

Removed mushroom shaped float cover by simply pulling up. Cover simply slide down into switch which is mounted through the floor of the tub. Using an adjustable wrench loosened and removed plastic fastening nut allowing removal of switch assembly from below. Disconnected two wires from switch and attached replacement assembly, reinserted in mounting hole, reattached nut from top, reinserted float cap and job done! The only tricky part is that the switch needs to be mounted inside assembly, wires connected and snapped shut before reinserting. Not difficult once you figure it out, Also need to make sure rubber washer is inserted on the overflow tube before reinstalling. Keep track as you remove and simply reverse the order. Tried to obtain part locally and was told it would be 6-10 days before delivery. Order from Part select arrived in 2 days.
