How to Fix / Troubleshooting

Safety first: Immediately close the water tap and unplug the dishwasher to prevent flooding.

Observe behavior: If water continues to enter the tub when the machine is off, the inlet valve is mechanically stuck open.
Inspect inlet valve: Access the valve (usually at the base where the inlet hose connects). Check for debris in the valve screen and ensure the plunger moves freely. Replace the valve if it leaks when de-energized.
Check wiring: Inspect the harness from the control board to the inlet valve for damage or short circuits that could hold the valve energized.
Control board: If the valve tests good but is being powered at the wrong time, the main control module may be faulty and require replacement.
Re-test: After replacing the faulty component, run a test cycle and monitor filling and draining closely.

Dishwasher displays F9, often associated with continuous filling or draining behavior.
