Display shows LO or low water icon; unit beeps and stops making ice.

Safety: Unplug the unit before removing the water tank on portable models.

Steps:

• Refill reservoir: Remove the water tank or open the reservoir lid and fill to the indicated MAX line with clean potable water.
• Check tank seating: Ensure the tank is fully inserted and properly aligned so that any internal valve or sensor is engaged.
• Inspect hoses: On plumbed-in SMAD ice makers, verify that the inlet hose is not kinked or pinched and that the supply valve is fully open.
• Clean level sensor: If LO persists with a full tank, clean the water level sensor or float as described in the E3 procedure.
• Replace sensor if needed: If the sensor does not change state when the water level is raised, replace the water level sensor assembly.
