Electrolux ice maker displays E09; water overflows the sump or ice thickness is excessive.

Safety First: Disconnect power and shut off water. Expect some water spillage when opening the sump area.

• Access float or sensor: Remove the ice bin and front panel to reach the water reservoir or sump. Locate the float switch or electronic level sensor.
• Clean scale and debris: Lift and lower the float to ensure free movement. Remove mineral scale and slime using a manufacturer-approved ice machine cleaner. Rinse thoroughly.
• Inspect switch or sensor: For mechanical floats, test continuity across the switch terminals while moving the float. For electronic sensors, inspect for cracks or corrosion and verify harness connections.
• Check wiring: Follow the harness back to the control board. Repair any damaged insulation or loose connectors.
• Replace level sensor: If the switch or sensor fails tests, install a new Electrolux water level sensor or float switch assembly. Reassemble, restore water and power, and run a test cycle.
