Dishwasher does not drain completely; a shallow pool of water remains under the filter after every cycle.

Safety first: Unplug the dishwasher before removing hoses or accessing the pump.

• Understand normal level: A small amount of water under the Fagor filter is normal to keep seals wet. Only troubleshoot if water is above the filter screen.
• Clean filters and sump: Ensure all filters and the sump are free of debris.
• Check drain hose height: Confirm the hose is installed with the correct height and no sags that can trap water.
• Inspect check valve: Access the drain outlet and check valve; clean or replace if it sticks open or closed.
