User Suggested Solutions

  1. Check and replace the heating element if faulty. To do this, unplug the dishwasher, remove the lower spray arm, and access the heating element for testing with a multimeter. Replace if necessary.

  2. Ensure proper loading of dishes. Avoid blocking the spray arms and ensure that items are placed in a way that allows for proper air circulation.

  3. Inspect and clean the drying fan. Remove the dishwasher cover, locate the fan, and ensure it is free of debris and functioning properly.

  4. Check the air vent for blockages. Clear any debris that may be obstructing airflow during the drying cycle.

  5. Verify the selected wash cycle is appropriate for drying. Use a cycle that includes a drying phase, such as 'Heavy' or 'Normal' with drying options.
