Maytag Dishwasher: not filling
What is this symptom?
Is your Maytag dishwasher not filling with water during a wash cycle? If the tub remains dry and the wash arms don't rotate, you may be facing issues with the water supply. This guide will help you identify the common causes and solutions to get your dishwasher back in action.
Important Tips for Maytag Models
- Maytag official guidance emphasizes checking water supply valve, door latch, and proper drain hose loop height (siphoning can affect fill).
Possible Causes
Water supply valve turned off or inadequate supply
How to Identify: Check if the external water supply valve (usually under the sink is fully open and water pressure is adequate.
Part: Water supply shut‑off valve / household supply line
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 ‘up’ 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 won’t start fill cycle; START/RESUME indicator may flash indicating door not latched.
Part: Door latch/interlock switch
Faulty control board or timer
How to Identify: All mechanical components appear functional but dishwasher does not signal water inlet valve to open; requires multimeter testing.
Part: Control board / timer
