How to fix it
- Confirm the water supply valve under the sink is fully open and the fill hose isn't kinked.
- Listen at the start of a cycle — a 4C5 with no valve click usually means the valve isn't being energized.
- Power off, pull the kick plate, and check the case/float switch — it should be DOWN with the tub empty.
- Test the inlet valve solenoid for ~500–1500 ohms; replace if open.
- If valve and float are good, check harness continuity to the main control board.
Why it happens
Typical signs: 4C5 or 4E5 on display · Tub remains dry after cycle start · No fill sound · Cycle ends in a few minutes
- Water inlet valve not opening Solenoid coil failed or no voltage from the control board.
- Closed supply valve House shutoff or angle stop closed.
- Faulty case (float) switch Float stuck up signals 'full' so the valve never energizes.
- Wiring fault to inlet valve Open or shorted harness between control and valve.
