Insignia ice maker stops mid-cycle and displays E2, no ice is produced.

Safety first: Unplug the unit before removing covers or reaching inside the water reservoir area.

• Empty and clean the reservoir: Remove all water and wipe the reservoir with a soft cloth. Check for debris or scale around the float or sensor area.
• Locate the float or sensor: On many Insignia countertop ice makers, a plastic float or electronic probe sits in the reservoir. Make sure the float moves freely up and down.
• Descale the sensor: If you see white mineral deposits, soak a cloth in a 1:1 mix of white vinegar and water and gently clean the float and sensor surfaces. Rinse thoroughly.
• Check wiring: From the reservoir area, trace the sensor wires to the control board. Ensure the connector is fully seated and not corroded.
• Reset and test: Refill with clean water (preferably filtered), plug in, and restart. If E2 returns immediately, the sensor assembly is likely defective and should be replaced.
