Display shows E5; ice production stops; water may not be freezing properly.

Safety first: Disconnect power before working inside the water reservoir area.

Steps to resolve E5:

• Empty and clean reservoir: Remove the water tank or reservoir (if removable) and empty it. Clean with warm water and mild dish soap to remove mineral deposits.
• Clean level probes/sensor: Many Galanz ice makers use metal level probes or a float sensor. Gently scrub the probes or float with a soft brush and white vinegar to remove scale that can interfere with sensing.
• Check float movement: If your model uses a float, ensure it moves freely up and down and is not stuck by debris.
• Inspect wiring: Trace the sensor wires back to the control board. Ensure connectors are tight and wires are not pinched.
• Replace sensor: If cleaning does not clear E5, replace the water level sensor assembly with a compatible Galanz part.
• Control board: If a new sensor does not resolve the error, the main control board may not be reading the signal correctly and may need replacement.

When to call a technician: If you are not comfortable accessing internal wiring or replacing the control board, contact a service professional.
