How to Fix / Troubleshooting

Safety first: Allow the dishwasher to cool before working near the heater or fan.

  • Check rinse aid: Ensure the rinse aid dispenser is filled and set to an appropriate dosage.
  • Use proper program: Select a program with drying and avoid quick or eco modes if maximum drying is desired.
  • Do not open door early: Allow the full cycle to complete and wait a few minutes before opening the door.
  • Check heater operation: If dishes are cold at end of cycle, test the heater and related components as described for heating faults.
  • Inspect drying fan (if equipped): Listen for fan operation during drying. Replace the fan if it does not run.
