Possible Causes

Hard water mineral deposits, Insufficient rinse aid, Too little detergent, Clogged softener (if equipped)

How to Fix / Troubleshooting

Safety: No special electrical safety concerns for this issue; avoid harsh chemicals without ventilation.

  • Adjust detergent: Use a high-quality detergent and adjust the amount based on water hardness. Harder water requires more detergent.
  • Use rinse aid: Ensure the rinse aid dispenser is filled and set to a higher dosage.
  • Clean with citric acid: Run an empty cycle with a dishwasher cleaner designed to remove mineral buildup or use a cup of citric acid crystals.
  • Water softener: If your JennAir dishwasher has a built-in softener, check and refill the salt reservoir as specified in the manual.

Note: Cloudy glass that does not clear with vinegar may be permanently etched from soft water and too much detergent.
