Dishwasher shows E17; machine fills and drains repeatedly without completing cycle

Safety first: Turn off power and water before adjusting plumbing connections.

• 1. Check drain hose height: Ensure the drain hose rises to the manufacturer-specified height above the floor before connecting to the drain. A hose that is too low can cause siphoning.
• 2. Inspect air break: If an air gap or break is installed, confirm it is not bypassed or blocked.
• 3. Clean pressure chamber: Locate the pressure chamber or tube connected to the level switch. Remove and flush it to clear grease or scale that may trap air.
• 4. Test pressure switch: With a multimeter, verify that the switch changes state at the correct water level (requires service specs).
• When to call a technician: If the control board misinterprets level signals or the pressure switch needs calibration, professional service is recommended.
