Ice with Abnormal Odor or Taste
Likely causes
Ice bin contamination (slime/mold)
Check: Visually inspect bin interior — pink/yellow slime or black mold; use UV light to detect microbial colonies
What to do: Immediately stop operation → discard all remaining ice → full wash with food-grade cleaner → rinse → restart
Supply line contamination
Check: Directly smell water supply hose/pipe — foreign odor = line contamination; simultaneously measure water TDS
What to do: Flush line (minimum 5 min at high flow); replace contaminated sections; use food-grade hose
Water basin/circulation pump slime
Check: Visually inspect water basin and circulation pump — check for viscous slime film; slime is the #1 cause of odor
What to do: Circulate nickel-safe cleaner 1:16~1:32 dilution for 1 hour → rinse 3 times; schedule preventive cleaning every 3 months
Absorption of ambient odors
Check: Check machine environment — exposure to smoke, cleaning chemicals, food odors; inspect bin lid and gasket sealing
What to do: Relocate or improve ventilation; replace damaged gasket — must pass 0.76mm paper test
Over 60% of ice odor cases are from bin contamination — check bin hygiene before water quality; contaminated ice must be discarded immediately (food safety)
