Welcome to our comprehensive guide on fixing the issue of the Thermador dishwasher not drying dishes. As a trusted authority in home appliances, we understand the frustration that comes with dishes coming out wet from the dishwasher when you expect them to be dry and ready to use. In this article, we’ll delve into the various reasons why your Thermador dishwasher might not be drying dishes effectively and provide you with practical solutions to resolve this issue.

Understanding the Problem

Several factors can contribute to your Thermador dishwasher failing to dry dishes properly. These may include:

  1. Improper Loading: Overloading the dishwasher or obstructing the vents can impede the smooth flow of air, thereby diminishing the effectiveness of the drying process. Properly arranging dishes ensures that hot air can circulate freely, aiding in thorough drying.
  2. Faulty Heating Element: The heating element plays a crucial role in generating the heat necessary for drying dishes. If it malfunctions or shows signs of damage, such as visible breaks or discoloration, it fails to provide adequate heat, resulting in dishes remaining wet after the cycle.
  3. Clogged Vent: The vent situated at the bottom of the dishwasher facilitates the release of hot air during the drying cycle. However, if it becomes obstructed by debris or buildup, the airflow is restricted, leading to moisture retention within the dishwasher and damp dishes.
  4. Faulty Thermostat: A dysfunctional thermostat disrupts the regulation of temperature within the dishwasher. As a consequence, the appliance may not attain the required temperature for effective drying, leaving dishes damp instead of dry.

Solutions to Fix the Issue

To rectify the problem of dishes not drying in your Thermador dishwasher, consider implementing the following solutions:

Proper Loading Techniques

  • Ensure that you load the dishwasher correctly to optimize airflow and promote efficient drying. Avoid overcrowding the dishwasher and arrange dishes in a manner that allows unrestricted circulation of hot air.

Check the Heating Element

  • Inspect the heating element for any signs of damage or malfunction. If you detect any issues such as breaks or discoloration, it’s indicative of a faulty heating element that needs replacement to restore proper drying functionality.

Clear the Vent

  • Examine the vent located at the bottom of the dishwasher for any obstructions. Clear away any debris or buildup that may be blocking the vent, thus hindering the escape of hot air and contributing to ineffective drying.

Test the Thermostat

  • Conduct a diagnostic test on the thermostat to verify its functionality. If the thermostat is found to be faulty, it may require recalibration or replacement by a professional technician to ensure that the dishwasher reaches the optimal temperature for drying.

Additional Tips for Optimal Drying

In addition to the aforementioned solutions, consider the following tips to enhance the drying performance of your Thermador dishwasher:

  • Utilize Rinse Aid: Adding a rinse aid to the dishwasher helps water evaporate more rapidly during the drying cycle, resulting in drier dishes.
  • Select Suitable Drying Cycle: Choose the appropriate drying cycle, such as the “Heated Dry” option, to maximize drying efficiency based on the load of dishes.
  • Time Your Dishwashing: Opt for off-peak hours to run the dishwasher when hot water usage is lower, ensuring that the appliance operates with optimal water temperature for effective drying.

Implementing these solutions and tips will help address the issue of dishes not drying in your Thermador dishwasher, ensuring that you consistently achieve dry and ready-to-use dishes after each wash cycle.


By following the troubleshooting steps outlined in this guide, you can effectively address the issue of your Thermador dishwasher not drying dishes. Remember to practice proper loading techniques, inspect key components such as the heating element and thermostat, and utilize additional tips for optimal drying results. If you continue to experience problems despite these efforts, it may be time to consult a professional technician for further assistance.
