Visible white scale or mineral buildup on the evaporator and internal surfaces.

Safety first: Unplug the ice maker before cleaning. Avoid inhaling cleaning vapors.

• Prepare descaling solution: Mix a manufacturer‑approved descaler or food‑grade citric acid with warm water per instructions.
• Soak affected areas: Apply solution to the evaporator, reservoir, and water distribution parts. Allow to soak until scale softens.
• Scrub gently: Use a soft brush or cloth to remove loosened deposits. Do not scratch the evaporator surface.
• Rinse thoroughly: Flush with clean water and run a rinse cycle, discarding the first batch of ice.
• Consider filtration: Install a water filter on the supply line to reduce future buildup.
