Ice maker shows E11 and stops; water remains in the sump or tray and does not drain properly.

Safety first: Unplug the unit and be prepared for water spillage when opening drain components.

• Inspect external drain hose: Check for kinks, sharp bends, or clogs. Detach the hose from the household drain and flush it with warm water.
• Clean internal drain channel: Remove the ice bin and internal covers to access the drain outlet. Use a flexible brush or pipe cleaner to remove slime or scale.
• Access drain pump: From the rear or bottom, locate the drain pump assembly. Remove any debris from the pump inlet and impeller area.
• Test pump: With power disconnected, measure pump coil resistance. If open or shorted, replace the pump. For further confirmation, briefly energize the pump (qualified persons only) to see if it runs.
• Reassemble and test: Refit all hoses securely, ensuring proper slope for gravity-assisted drainage. Restore power and run a test cycle to confirm E11 is cleared.
