Ice has a bad taste or odor (chemical, musty, or metallic).

Safety first: Disconnect power and close the water supply. Discard all existing ice.

• Clean the bin: Remove the ice storage bin if possible. Wash with warm water and mild detergent, then rinse thoroughly. Sanitize with a food‑safe sanitizer.
• Clean water reservoir and lines: Run a full cleaning cycle using Gram‑approved ice maker cleaner. Follow with multiple rinse cycles to remove any cleaner residue.
• Replace water filter (if equipped): If your Gram ice maker has an inline or internal water filter, replace it according to the schedule or sooner if taste issues occur.
• Check water source: If the household water has strong odors, consider installing a dedicated filtration system.
