IceKing ice maker displays E6 and stops; ice cubes may be misshapen or production is inconsistent.

Safety first: Unplug the ice maker and shut off the water supply before working on the water system.

Step-by-step checks:

• 1. Access the water reservoir: Remove the ice bin and any internal covers to expose the water tank/reservoir area.
• 2. Identify the level sensor: Depending on model, IceKing units may use a mechanical float switch or metal water level probes.
• 3. Clean scale and slime: If you see mineral deposits or slime on the float or probes, clean them with a soft brush and a mixture of warm water and mild vinegar. Rinse thoroughly.
• 4. Check float movement: Manually move the float up and down. It should move freely without sticking. If it binds, clean or replace the float assembly.
• 5. Inspect wiring: Ensure the sensor or float switch wiring harness is intact and firmly connected to the control board.
• 6. Reset and test: Reassemble, restore water and power, then run a test cycle. If E6 reappears, the water level sensor/float switch is likely defective and should be replaced.

When to call a technician: If the sensor is integrated into a larger water tank assembly or requires significant disassembly, professional service is recommended.
