Ice maker produces ice but the cubes have a bad taste or odor.

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

• Drain and clean: Empty the reservoir and ice bin. Wash them with warm water and mild dish soap, then rinse thoroughly.
• Descale system: Run a cleaning cycle with food-safe descaler or a mixture of water and white vinegar (follow Klarstein guidelines). Discard all ice produced during and immediately after cleaning.
• Use fresh water: Always use fresh, potable water and change it daily if the unit is not used continuously.
• Relocate unit: Keep the ice maker away from strong-smelling items (cleaners, garbage, spices) that can transfer odors through air intake.

Persistent bad taste after thorough cleaning may indicate biofilm in internal hoses or pump, which may require component replacement.
