Clogged or defective water inlet valve

How to Identify: Dishwasher remains dry with no water entering; buzzing from valve but no water flow; check for debris at valve screen or failed solenoid.

Part: Water inlet valve

Stuck or faulty float/float switch

How to Identify: Float stuck in â€˜upâ€™ position or float switch fails continuity test; dishwasher thinks it is already full thus preventing water intake.

Part: Float assembly and float switch

Door latch or door switch problem

How to Identify: Dishwasher wonâ€™t start fill cycle; START/RESUME indicator may flash indicating door not latched.

Part: Door latch/interlock switch

Faulty control board or timer

Part: Control board / timer
