Display shows E2 and ice production stops; unit may start but quickly aborts the cycle.

Safety: Unplug the ice maker before removing the top cover or reservoir parts.

• Empty and clean reservoir: Remove the ice basket and drain any water using the drain plug. Rinse the reservoir with warm water and a small amount of white vinegar to dissolve mineral deposits.
• Free the float: Locate the plastic float or water level sensor assembly in the reservoir. Move it up and down gently to ensure it moves freely. If it is stuck, clean around the guide tube and pivot points.
• Descale components: Soak the float and its guide in a 1:1 vinegar and warm water solution for 15–20 minutes, then rinse thoroughly.
• Check wiring: Inspect the two-wire harness from the float sensor to the control board for cuts, pinches, or loose connectors. Reseat the connector on the board.
• Test operation: Refill the reservoir to the MAX line with clean water, reinstall the ice basket, plug in the unit, and restart. If E2 clears, monitor for normal operation.
• Replace sensor if needed: If E2 returns and the float moves freely, replace the water level sensor/float switch assembly with a compatible Kismile part.
