6.3 Descaling
Mineral buildup from hard water can affect ice production and quality. Regular descaling is essential. The frequency depends on your water hardness:
- Moderately Hard Water: Descale once a month.
- Hard to Very Hard Water: Descale every 2-3 weeks.
To descale, use a mixture of water and white vinegar or a commercial descaling solution designed for ice makers. Follow the product's instructions for the descaling solution, or run the self-cleaning cycle with the vinegar solution, then rinse thoroughly with clean water multiple times.
