Quick answer

If your dishwasher isn't heat drying dishes, check the heat dry setting is enabled, ensure the heating element is working, and look for error codes. Reset the unit if needed.

Confirm the symptom

• Dishes are wet after a full cycle
• Heat dry setting is enabled but not activating
• No warm air during the dry cycle
• Error code related to heating or drying

Tools and prep

• Screwdriver set
• Multimeter (for testing electrical components)
• Owner's manual
• Rubber gloves
• Turn off power at the circuit breaker before testing
• Ensure the dishwasher is unplugged or disconnected

Step-by-step troubleshooting

1. Check Heat Dry Setting
   Do: Verify the dishwasher's heat dry option is turned on.
   Observe: The setting is enabled but dishes remain wet.
   Means: The issue is likely not a setting problem.
   Next: Test the heating element
2. Test the Heating Element
   Do: Use a multimeter to check for continuity in the heating element.
   Observe: No continuity indicates a faulty element.
   Means: The heating element needs replacement.
   Next: Replace the heating element
3. Inspect for Error Codes
   Do: Check the dishwasher's display for error codes related to heating or drying.
   Observe: An error code is displayed.
   Means: The error code provides a direct clue to the issue.
   Next: Refer to the owner's manual for code interpretation
4. Check the Thermostat
   Do: Test the thermostat with a multimeter to ensure it’s functioning correctly.
   Observe: The thermostat is not closing the circuit when heated.
   Means: A faulty thermostat is preventing heat dry.
   Next: Replace the thermostat
5. Inspect the Control Board
   Do: Look for visible damage or burn marks on the control board.
   Observe: Damage or burn marks are present.
   Means: The control board may be malfunctioning.
   Next: Replace the control board
6. Check the Door Latch and Seal
   Do: Ensure the door is latching fully and the gasket is intact.
   Observe: The door does not seal properly.
   Means: Heat is escaping, preventing effective drying.
   Next: Repair or replace the door latch or gasket
