F09 appears and the washer-dryer may stop with water still in the drum.

Safety first: Unplug the appliance and shut off water supply. Be prepared for water spillage.

• Drain excess water: Use the drain pump clean-out or gravity drain via the drain hose into a bucket to remove water from the drum.
• Inspect inlet valves: With water supply off and hoses removed, check if water still seeps through the valve into the tub. If so, the valve is stuck open and must be replaced.
• Check pressure system: Verify the pressure hose from tub to switch is not blocked with detergent residue or lint. Clean or replace the hose. Ensure the pressure switch is mounted upright and secure.
• Replace faulty components: If the pressure switch fails continuity tests or the valve leaks, install new KitchenAid parts. Reconnect all hoses and wiring securely.
• Test operation: Restore power and water, then run a rinse and spin cycle to confirm no overflow and that F09 is cleared.
