E5 error on display; unit stops and may drain water repeatedly

Safety first: Turn off the water supply and disconnect power before working on the water system. Expect some water spillage; keep towels and a shallow pan ready.

• Step 1 – Verify water supply: Confirm the shutoff valve to the ice maker is fully open and that other fixtures in the home have normal pressure.
• Step 2 – Inspect supply line: Check the copper or braided line to the ice maker for kinks, crushing, or freezing (in cold locations). Straighten or thaw as needed.
• Step 3 – Clean inlet screen: Remove the rear access panel to reach the water inlet valve. Turn off water, disconnect the inlet line, and inspect the valve’s screen for debris. Clean gently with a small brush.
• Step 4 – Test water inlet valve: With power off, disconnect the valve coil wires and measure coil resistance. An open coil indicates a bad valve. With power on and a call for water, you should measure 120 VAC (or rated voltage) at the coil. If voltage is present but no water flows, replace the valve.
• Step 5 – Check water level sensor: Some Viking models use a float or electronic water level sensor in the reservoir. Inspect for obstructions, scale buildup, or stuck floats. Clean and ensure free movement.

After correcting the water supply issue or replacing the valve, restore power, clear the E5 code, and confirm that the reservoir fills to the proper level and the unit begins a freeze cycle.
