Possible Causes

Dirty water reservoir, mold or slime in bin, old or contaminated water supply, new plastic components off-gassing.

How to Fix / Troubleshooting

Safety first: Unplug the unit and shut off water before cleaning. Do not mix cleaning chemicals.

  • Discard old ice: Empty the bin completely and discard any ice with off‑odors.
  • Clean interior: Wash the bin, reservoir, and accessible water paths with warm water and mild dish soap. Rinse thoroughly.
  • Sanitize: Use a food‑safe ice machine cleaner or a diluted bleach solution (per manufacturer instructions) to sanitize surfaces. Rinse until no odor remains.
  • Flush system: Run and discard the first 2–3 batches of ice after cleaning.
  • Check water source: If taste issues persist, consider adding or replacing an inline water filter and verify the household water quality.
