Viking Overfill / Water Level Control Failure

Ice maker fills with too much water and overflows into the bin.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Stuck water inlet valve, faulty water level sensor or float, control board not shutting off fill, scale causing float to stick.

Safety first: Turn off the water supply and power immediately to stop the overflow and prevent electrical hazards.

Step 1 – Inspect float or level sensor: Open the reservoir area and check if the float moves freely. Clean any scale or debris.
Step 2 – Test inlet valve: With the water supply turned off and the line disconnected, check if water continues to drip from the valve outlet. Any leakage with no power applied indicates a faulty valve that must be replaced.
Step 3 – Check control response: After cleaning and replacing parts, observe a fill cycle to ensure the valve shuts off at the correct level.

Do not operate the unit until the overfill condition is fully resolved.
