Ice has a bad taste or odor, even though the ice maker appears to be working normally.

Safety: Disconnect power and shut off water before cleaning. Use only food-safe cleaners recommended by Sub-Zero.

Steps to improve ice quality:

• 1. Discard old ice: Empty the ice bin completely and wash it with warm water and mild detergent. Rinse and dry thoroughly.
• 2. Run cleaning and sanitizing cycles: Follow the user manual to run a full cleaning cycle with Sub-Zero-approved cleaner, followed by a sanitizing rinse.
• 3. Check water supply: If the household water has odor or taste issues, install or replace a water filter upstream of the ice maker. Sub-Zero recommends high-quality filtration.
• 4. Ventilation: Ensure no strong-smelling chemicals or foods are stored near the ice bin that could transfer odors.
• 5. Repeat flushing: After cleaning, discard the first few batches of ice to ensure all cleaner and contaminants are flushed out.
