What this code means
The dishwasher did not reach the expected water level during filling. The first checks are the water valve, inlet line, pressure and installation—not the circulation pump.
Most likely causes
- The water supply valve is closed or household water pressure is below the operating range
- The inlet line is kinked, frozen or obstructed
- A flood-safe hose or check device is interrupting water flow
- The dishwasher is not level, is siphoning water out, or has a valve/flow-sensing fault
Safe checks for the owner
- Confirm the dishwasher water shutoff valve is fully open.
- Inspect the water line for sharp bends and verify that the home supply is available.
- Check that the drain hose is routed at the required height so water cannot siphon out.
Estimated U.S. repair cost
$190–$360, depending on model, access, parts availability and local labor.
