Dishwasher shows E13 and may stop with water remaining or unusual noises.

Safety first: Disconnect power and be cautious of sharp metal edges when removing panels.

• Clean filters and sump: Ensure the sump area is free of debris that could affect water level and drainage.
• Locate pressure sensor: Many Baumatic models use a small electronic pressure sensor connected by a thin hose to the sump or side chamber.
• Clean hose: Remove the hose and blow through it to clear any grease or sludge. Rinse with hot water if necessary and refit securely.
• Inspect sensor and wiring: Check the sensor body for cracks or water ingress and ensure the connector is firmly attached.
• Replace sensor: If E13 persists after cleaning, replace the drain pressure sensor. If the fault remains, the control board may be at fault.
