Viking Ice Machine Not Making Ice or Leaking Water:... | appliancefaults.com

Technical Background:

MCU logic and voltage paths. The ice machine's main control unit (MCU) regulates the ice-making process. The MCU receives signals from the ice thickness sensor, water level sensor, and other components. It then controls the water inlet valve, ice harvest cycle, and drain cycle. Voltage paths include 120V AC to the MCU and various DC voltages to sensors and actuators.

Symptoms:

US homeowner observations. The Viking ice machine is not producing ice, and there is a noticeable water leak in or around the unit.

Possible Causes:

Clogged water filter restricting water flow.
Defective water inlet valve preventing water from entering.
Faulty ice thickness sensor not signaling ice harvest.
Frozen or blocked drain line causing water overflow.
Damaged or leaking water line connections.

Solution:

1

Unplug the ice machine or turn off the breaker at the breaker panel.
2

Inspect and replace the water filter. Refer to the user manual for the correct filter type. A new filter should allow adequate water flow (approximately 40 PSI).
3

Check the water inlet valve using a multimeter for continuity. If no continuity, replace the valve.
4

Examine the ice thickness sensor. If visibly damaged or testing out of range (refer to service manual resistance values), replace it.
5

Clear the drain line using warm water and a small diameter tube or wire. Ensure the drain line is properly positioned and not kinked.
6

Inspect all water line connections for leaks. Tighten fittings or replace damaged water lines.
7

After completing repairs, restore power and monitor the ice machine for proper ice production and water leaks.

Safety Warning:

Lock Out/Tag Out (LOTO) the power supply at the breaker panel before performing any repairs. The ice machine operates on 120V AC, which can cause severe electric shock.

Prevention:

Regularly replace the water filter every 6 months or as recommended by the manufacturer. Periodically clean the ice machine interior with a mild detergent and water solution. Inspect water lines and connections for leaks at least annually.

Expert Tip:

Many Viking ice machines have a service mode that allows for manual activation of components like the water inlet valve and harvest cycle. Refer to the service manual for the specific service mode entry sequence for your model.

Frequently Asked Questions

•How do I access the water inlet valve to test it?

The water inlet valve is typically located at the back of the ice machine, near the water supply connection. You may need to remove a back panel using a 1/4-inch nut driver to access it.

•Where is the drain line located, and how do I know if it's frozen?

The drain line typically exits the ice machine near the bottom. Check for ice blockage by visually inspecting the line or feeling for cold spots. You can use a heat gun on low setting or warm water to thaw the line.

•What are the correct resistance values for the ice thickness sensor?

The resistance values for the ice thickness sensor vary depending on the specific model. Refer to the service manual for your model to find the correct resistance range at different ice thicknesses. The service manual often includes a resistance table vs temperature chart
