Display shows E15; ice level may not be detected correctly, causing overfilling or no ice production.

Safety first: Disconnect power before working around the ice bin and sensor boards.

Steps:

• Locate ice level sensor: Many Viking models use infrared optics on the side walls of the ice compartment.
• Clean sensor windows: Use a soft cloth and mild soap solution to clean the emitter and receiver windows. Dry thoroughly.
• Check bin position: Ensure the ice bin is fully seated and not blocking the sensor beam.
• Visual inspection: Inspect the optics boards for corrosion, cracked housings, or loose connectors.

Corrective action: If cleaning and reseating do not restore normal operation, replace the ice level optics kit (emitter and receiver boards) as a set to ensure proper calibration.
