IceKing ice maker displays E18; unit may shut down with an internal leak detected.

Safety first: Unplug the ice maker and shut off the water supply immediately to prevent further leakage.

Step-by-step checks:

• 1. Inspect around unit: Look for water under or around the IceKing cabinet. Dry the area.
• 2. Remove panels: Take off the lower front or rear panel to inspect inside the base for standing water and the leak/overflow sensor (often a float or moisture sensor).
• 3. Identify leak source: Check all internal hoses, clamps, the water reservoir, and connections to the inlet valve and pump for drips or cracks.
• 4. Tighten or replace: Tighten loose hose clamps and replace any cracked hoses or damaged reservoir components.
• 5. Dry sensor area: Dry the leak sensor and base thoroughly. Some models require a reset after the sensor dries.
• 6. Monitor for recurrence: Restore water and power, then observe the unit during operation for any new leaks.

When to call a technician: If the leak source is not obvious, or if water has reached electrical components or insulation, professional diagnosis is strongly recommended.
