Possible Causes

High mineral content in water, Insufficient purge or rinse cycle, Scale buildup on the evaporator, Incorrect water filtration.

How to Fix / Troubleshooting

Safety First: Disconnect power and water before cleaning.

  • Check water quality: Test water hardness and Total Dissolved Solids (TDS). Consider installing or upgrading a filtration/softening system approved for ice machines.
  • Descale evaporator: Clean the evaporator and water system with a nickel-safe cleaner to remove mineral film.
  • Verify purge operation: Observe that the unit performs proper purge/rinse cycles between freeze cycles. If not, consult the service manual for necessary adjustments.
  • Replace filter: Install a new filter designed specifically for ice machines, not just taste/odor filters.

When to call a technician: If cloudy ice persists with good water quality and clean components, control settings may need adjustment.
