Safety first: Disconnect power and close the water tap before working on the appliance.

Restart and listen: Restart a quick program and listen during the initial fill. If you hear only a faint hum and no water entering, suspect a fill restriction.
Recheck inlet hose and tap: Confirm the Panasonic inlet hose is not kinked and the tap is fully open. Remove and flush the hose to clear any debris.
Clean inlet valve filter: Remove the hose from the valve side and clean the mesh filter on the valve body. Sediment here is a common cause of H02.
Inspect flow meter / water level sensor: On many Panasonic dishwashers, a flow meter or water level sensor is integrated into the side water chamber or inlet assembly. Remove the left side panel, locate the transparent water matrix, and check for scale or debris blocking channels. Rinse with warm water and a soft brush.
Run a test cycle: Reassemble, restore power and water, and run a short cycle to confirm normal filling.

If H02 returns, the flow meter or control board may require replacement and should be diagnosed by a professional.

Dishwasher stops mid-cycle and displays H02 (or H2), dishes remain dirty and dry
