I have a Kenmore Elite Dishwasher Model 665-13733K604. Was working fine, then next load just won't turn on. Will occasionally light up smart wash, heated dry, and blinks on normal, will let me cancel those lights but will not turn on. The overfill float moves up and down freely and I don't see any obstruction within the machine. Is there a specific reset code for this washer? I have tried some sequences to no avail. Please help if you can.
