What's Happening
The dishwasher isn't getting water from the supply. Common causes include a closed water supply valve under the sink, a kinked inlet hose, a clogged inlet screen filter, or low water pressure below 20 PSI. On some models this displays as 4E.
How to Fix It
Check that the supply valve under the sink is fully open. Inspect the inlet hose for kinks. Clean the small mesh filter screen where the hose connects to the dishwasher. Avoid FloodSafe-style hoses as they can restrict flow. If supply is fine, the water inlet valve may need replacement.
