Visible corrosion or white powdery deposits around heating block

Safety: Unplug the unit and allow it to cool. Wear gloves and eye protection when cleaning corrosion.

• Disassemble base: Remove the base cover to fully expose the heating block and surrounding area.
• Identify leak source: Look for dampness around hose connections, seals, and the heating block. Tighten clamps and replace seals or hoses as needed.
• Clean corrosion: Gently brush away loose deposits with a dry brush. Wipe the area with a slightly damp cloth and dry thoroughly. Avoid getting water into electrical components.
• Inspect block integrity: If corrosion originates from a crack in the heating block, replace the entire block assembly.
• Prevent future leaks: Ensure all connections are secure and avoid overfilling the reservoir.
