E9 appears and the unit stops mid-cycle; water may overflow or not drain correctly from the ice tray.

Safety first: Disconnect power before accessing internal water components.

Steps:

• Drain and clean reservoir: Remove all water from the tank. Rinse with warm water and a small amount of white vinegar to dissolve mineral deposits, then rinse thoroughly.
• Clean pump inlet filter: Many Gastroback ice makers have a small mesh filter at the pump intake. Remove and rinse this filter to clear debris.
• Check internal hoses (if accessible): Ensure hoses from the pump to the ice tray are not kinked or pinched. Straighten any bends.
• Run a cleaning cycle: If your model has a CLEAN function, run it with a diluted vinegar solution, then flush with fresh water.

If E9 persists and you cannot hear the pump running during the fill phase, the pump motor may need replacement.
