E5 error appears and ice production stops mid-cycle.

Safety: Unplug the ice maker and drain water before working inside the reservoir.

• Check water level: Remove the ice basket and inspect the water reservoir. Ensure it is filled to the correct level mark.
• Inspect float assembly: Locate the float or water level probe in the reservoir. Move the float up and down; it should move freely without sticking.
• Clean mineral deposits: If the float or sensor is coated with scale, clean it with a soft brush and a mixture of warm water and white vinegar. Rinse thoroughly.
• Check wiring: Follow the float/sensor wires to the control board. Ensure connectors are tight and wires are not broken.
• Test switch/sensor: For a float switch, disconnect and test continuity with a multimeter while moving the float. For an electronic level sensor, compare resistance or voltage per service data. Replace if readings are incorrect.
• Reassemble and test: Refill the reservoir, restore power, and run a cycle to confirm the E5 code is cleared.
