How to Fix / Troubleshooting

Safety first: No electrical work is required for this issue.

  • Use rinse aid: Fill and adjust the rinse aid dispenser to a higher setting.
  • Adjust detergent: Use high-quality detergent and increase the amount slightly if you have hard water.
  • Increase water temperature: Run hot water at the sink before starting the dishwasher to ensure hot water enters immediately.
  • Clean spray arms: Remove and clean spray arms to ensure strong water flow.
  • Descale dishwasher: Run an empty cycle with a dishwasher cleaner or white vinegar (in a dishwasher-safe cup on the top rack) to remove mineral buildup.
