Ice maker makes ice but cubes are too small or thin

Safety first: Turn off water and power before disconnecting any water lines.

• Step 1 – Check water pressure: Ensure the supply line is at the recommended pressure (typically 20–120 psi). Avoid self-piercing saddle valves; use a full-port valve.
• Step 2 – Clean inlet valve screen: Remove the supply line at the valve and clean any debris from the screen.
• Step 3 – Verify reservoir level: During fill, confirm that the water reservoir reaches the proper level. If consistently low, test and replace the water level sensor or float assembly.
• Step 4 – Adjust ice thickness: If your Viking model has an ice thickness adjustment, increase the setting slightly to allow a thicker slab before harvest.

After adjustments, allow several cycles for the new ice thickness to stabilize.
