Ice maker produces no ice, but the evaporator plate gets very cold and frosts over.

Safety first: Disconnect power and close the water supply.

• Check water level: Open the bin and inspect the sump. If water level is low or empty, verify that the inlet valve is filling correctly and that the level sensor allows filling.
• Inspect spray bar: Remove the water distribution tube or spray bar above the evaporator. Clean any mineral deposits or debris from the holes.
• Test circulation pump: Start a cycle and listen for pump operation. If silent, test the pump as described under E12 and replace if necessary.
• Clean level sensor: Remove scale from the float or electronic level sensor so it can accurately detect water level.
