Dishwasher stops and shows F7, often related to water level problems (overfill or underfill).

Safety first: Disconnect power and water supply.

• Check for overfilling: If the tub is too full, manually remove excess water with a container and sponge.
• Inspect pressure hose: Access the pressure switch and its thin hose from the sump. Remove the hose and blow through it to clear any blockage. Clean the connection point on the sump.
• Test inlet valve: If water continues to enter the dishwasher even when off, the inlet valve is stuck open and must be replaced immediately.
• Check water softener valve: On models with integrated softener, ensure the regeneration valve is not stuck open, causing incorrect water routing.
• Re-test: After cleaning and inspection, run a short cycle. Persistent F7 usually indicates a defective pressure switch or sensor that needs replacement.
