E18 displayed, internal leak tray or base pan full of water, leak sensor triggered.

Safety: Unplug the unit and turn off the water supply immediately to prevent further leakage.

• Access base pan: Remove the front kick plate or rear panel to inspect the base of the Zanussi ice maker for standing water.
• Dry and inspect: Use towels or a wet/dry vacuum to remove water. Once dry, look for mineral trails or drip marks that indicate the leak source.
• Check hoses and clamps: Inspect all visible water lines and clamps from the inlet valve to the reservoir and evaporator. Tighten or replace any loose or cracked fittings.
• Inspect reservoir and tank: Look for hairline cracks or seams leaking on the plastic reservoir. Replace the reservoir if damaged.
• Check inlet valve body: Examine the valve for leaks around the solenoid or plastic housing. Replace the valve if it seeps when pressurized.
• Clear internal drains: Ensure internal drain channels are not blocked by scale or debris, which can cause overflow into the base pan.
• Reset leak sensor: Once the leak is repaired and the base is dry, reset or dry the leak sensor and restore power. Confirm that E18 clears and no new leaks appear.
