Start with supply conditions
Confirm the water shutoff valve is open and the supply hose is not kinked, frozen, or pinched. For washers, both hot and cold supply can matter even on cycles that seem to use one temperature.
A dishwasher fill problem can also come from a supply valve under the sink that was partly closed during plumbing work.
Watch for overflow behavior
A fill code means too little water on many models, but an overflow code or uncontrolled filling is different. If water keeps entering after cancellation, shut off the supply and stop.
Do not bypass float switches, leak sensors, door switches, or pressure sensing parts. Those controls exist to prevent water damage.
- Check external valves first.
- Look for kinked or crushed hoses.
- Confirm water is not still entering after cancel.
- Record whether the code appears before washing begins.
When screens and valves are not user work
Some inlet screens are accessible for cleaning; others require hose removal or panel access. Use the model manual as the boundary.
If the code remains after simple supply checks, the next useful step is model-specific support, not repeated resets.
