Machine fills but does not drain at end of cycle; display shows E2 and water remains in the tank.

Safety first: Disconnect power at the breaker and allow hot water to cool before working inside the tank.

Step-by-step checks:

• Clean scrap and drain screens: Remove the tank scrap tray and drain screen. Rinse thoroughly to remove food debris and foreign objects that may block water flow.
• Inspect drain opening: Look into the drain opening for utensils, labels, or heavy debris. Use gloves and remove any obstruction.
• Check drain hose: Trace the drain hose from the machine to the floor drain or sink. Ensure there are no kinks, sags filled with grease, or clogs. Flush the hose with hot water if possible.
• Test drain solenoid or pump: With power OFF, access the drain solenoid (on gravity-drain models) or drain pump (on pumped-drain models). Inspect wiring connections and look for signs of overheating or leakage. Use a multimeter to check the coil for continuity. Replace the solenoid or pump if open or seized.
• Verify drain air gap (if installed): Make sure the air gap is not blocked with debris or scale.

When to call a technician: If the drain solenoid or pump requires replacement or you find damaged wiring, have a qualified technician perform the repair.
