What this code means
The dishwasher did not receive the expected water flow or fill level within the allowed time.
Most likely causes
- The household shutoff valve is closed or water pressure is low
- The supply hose is kinked or the inlet screen is clogged
- The inlet valve or flow meter is faulty
- A connector, harness or main control is not receiving flow feedback
Safe checks for the owner
- Confirm the dishwasher shutoff valve under the sink is fully open.
- Inspect the supply hose for kinks and recent plumbing work.
- Turn off power and water before checking any accessible inlet screen.
Estimated U.S. repair cost
