Possible Causes

Dirty water reservoir, Biofilm or algae in hoses and pump, Use of unfiltered or heavily chlorinated water, Long periods of storage without cleaning

How to Fix / Troubleshooting

Safety first: Unplug the unit before cleaning. Do not use harsh chemicals inside the ice maker.

Steps to improve taste and odor:

  • Drain and clean: Open the drain plug and empty the reservoir. Clean the tank with a mixture of warm water and white vinegar (1:1). Wipe all accessible surfaces.
  • Run cleaning cycle: If your Silonn model has a cleaning mode, fill the reservoir with the vinegar solution and run the cleaning cycle as per the manual.
  • Rinse thoroughly: Drain the cleaning solution, then refill with fresh water and run at least 2–3 full ice cycles. Discard the first batches of ice.
  • Use better water: Use filtered, potable water to reduce minerals and off‑flavors.
  • Regular maintenance: Clean the unit every 1–2 weeks in heavy use, or before and after long storage.

When to call a professional: If odor persists despite thorough cleaning, internal hoses or the reservoir may need replacement.
