Cove Dishwasher Water Spots on Racks and Dishes

Cause:

  • Water temperature too low
  • Water temperature too high (flash drying)
  • Not using enough detergent
  • Using too much detergent in soft water
  • Undissolved granular detergent
  • Dispenser cup malfunction
  • Water supply change
  • Water softener hardness setting not correct (softener model only)
  • Not using rinse aid

Topics:

  • Glasses are not clean
  • Glassware comes out of Cove dishwasher with spots or streaks
  • White film on silverware
  • Glassware is cloudy, spotty or streaked
  • Spots on Dishwasher racks or tub

Answer:

To avoid spotting or streaking on glassware or dishes washed in a dishwasher:

  • Check the Water Softener hardness setting. The default is 0. Change the setting to at least 5. Refer to Cove Dishwasher Water Hardness for more information (softener model only).
  • Verify salt compartment is not empty. See Cove Dishwasher Water Softener (softener model only).
  • Ensure a quick or rinse cycle is not being run.
    • On the softener model, these cycles do not regenerate the softener.
    • If there is a noticeable pause before the wash cycle starts, this is the regeneration process and is normal.
  • Verify type and amount of detergent being used. See Cove Dishwasher Detergent Suggestions.
  • Use a rinse aid to reduce streaking and spotting. Refer to Cove Dishwasher Adding Rinse Aid.
  • Run a Normal cycle with high temp wash and sani rinse turned on. Put a cup of vinegar in a cup or bowl, and set it in the lower rack facing upright.
  • Do not overload the machine. Water should circulate freely to ensure adequate rinsing and draining.
  • Use a lower water temperature setting.
  • Do not use heated dry option.
  • Do not pre-rinse dishes. Only scrape off large particles and load the dishes into the machine.
    • Cove Dishwashers are designed to work best with some food residue. Without this residue, the unit can over clean, leading to film and spots.
