  • Discard old ice: Empty the ice bin completely and discard any ice with off‑odors.
  • Clean reservoir and bin: Wash the water tank, ice bin, and internal surfaces with warm water and a mild, food‑safe detergent. Rinse thoroughly.
  • Descale system: Run a Hoover‑approved ice maker cleaner/descaler through the system following the user manual. This removes mineral deposits and biofilm.
  • Flush with fresh water: After cleaning, run at least one full cycle and discard the first batch of ice.
