Excessive frost or ice buildup on the evaporator and surrounding plastic parts.

Safety first: Unplug the ice maker before defrosting. Do not use sharp tools or hair dryers.

Steps:

• Manual defrost: Remove the ice basket and allow the unit to sit unplugged with the lid open until all frost has melted. Place towels to catch water.
• Clean evaporator: After defrosting, wipe the evaporator with a descaling solution to remove mineral deposits, then rinse and dry.
• Adjust usage: Avoid leaving the lid open for long periods and operate the unit in a less humid room if possible.

Frequent heavy frost buildup may indicate a temperature control or sensor issue that should be checked by a technician.
