Display shows E5, unit may power on but will not start an ice-making cycle.

Safety: Unplug the ice maker and shut off the water supply before disconnecting any water lines.

Diagnostic steps:

• 1. Check water supply: Confirm the household shutoff valve is fully open and the supply line to the Avanti ice maker is not kinked or pinched.
• 2. Inspect inlet screen: Disconnect the water line at the inlet valve on the back of the unit. Look for debris in the valve screen and gently clean with a small brush if clogged.
• 3. Verify water flow: Briefly open the supply line into a bucket to confirm strong water flow from the house plumbing (then shut it off again).
• 4. Check reservoir water level sensor: Remove the top or front cover to access the water reservoir. Many Avanti models use a float switch or electronic level sensor. Ensure the float moves freely and is not stuck by scale or slime.
• 5. Test inlet valve coil: With power disconnected, measure resistance across the inlet valve terminals. An open circuit indicates a failed valve that must be replaced.
• 6. Clean reservoir: If mineral buildup is present, clean the reservoir and float with a mixture of warm water and ice maker cleaner, then rinse thoroughly.
