Ice has an unusual taste or odor (plastic, chemical, or musty).

Safety first: Unplug the unit before cleaning. Do not use harsh chemicals that are not food-safe.

Steps to improve taste and odor:

• 1. Discard old ice: Throw away all existing ice and drain the reservoir completely.
• 2. Deep clean reservoir and bin: Wash the water reservoir, ice basket, and interior surfaces with warm water and mild dish soap. Rinse thoroughly.
• 3. Descale and sanitize: Fill the reservoir with a mixture of 1 part white vinegar to 3 parts water. Run a cleaning cycle if available, or run a few ice-making cycles and discard the ice. Then flush with two full reservoirs of clean water.
• 4. Clean hoses and pump: If accessible, wipe internal hoses and pump inlet with a cloth soaked in the vinegar solution, then rinse.
• 5. Use filtered water: Going forward, use fresh, filtered water and change it daily if the unit is not used continuously.

Note: Persistent musty odors may indicate mold growth in inaccessible areas; in that case, consider professional cleaning or replacing heavily contaminated parts.
