Cove Dishwasher Water Spots or White Film on Racks and Dishes


  • 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


  • 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


If spotting or streaking appears on glassware or dishes washed in a dishwasher:

  1. For softener models, 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.
  2. For softener models, verify salt compartment is not empty. See Cove Dishwasher Water Softener.
  3. Make sure 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.
  4. Verify type and amount of detergent being used. See Cove Dishwasher Detergent Suggestions.
  5. Use a rinse aid to reduce streaking and spotting. Refer to Cove Dishwasher Adding Rinse Aid.
  6. 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.
  7. When loading the dishwasher:
    • Do not prerinse dishes. Only scrape off large particles and load the dishes into the machine. Cove Dishwashers work best with some food residue. Without residue, the unit can over clean, leading to film and spots.
    • Do not overload the machine. Water should circulate freely for adequate rinsing and draining.
    • Do not use high temp wash option.
    • Do not use sani rinse option.
    • Do not use heated dry option.
