How to fix it
- Verify the water supply valve under the sink is fully open.
- Inspect the fill hose for kinks behind the dishwasher.
- Shut off water, disconnect fill hose at the valve, and clean the inlet screen.
- Test that water flow at the supply line fills a quart container in under 10 seconds.
- If supply is good, suspect the inlet valve or case/float switch.
