Understanding the Dreaded F20 Error Code: Communication Error Between the Machine Control and the Motor Control

Has your trusty Whirlpool dryer suddenly come to a grinding halt, displaying an F20 error code on its digital display? Don’t panic! While this error might seem intimidating at first, it is actually a common issue faced by many Whirlpool dryer owners. And lucky for you, I’m here to shed some light on this error and guide you through the troubleshooting process.

So, what exactly does the F20 error code mean? Well, it typically indicates a communication failure between the machine control (also known as the main control board) and the motor control of your Whirlpool dryer. This breakdown in communication can be caused by a range of factors, including electrical problems, faulty connections, or even a glitch in the control board itself.

Key Takeaways:

  • The F20 error code on your Whirlpool dryer indicates a communication breakdown, but don’t fret! Simple troubleshooting steps like checking power supply and inspecting wiring connections can often resolve the issue.
  • If you’re unable to fix the F20 error code on your Whirlpool dryer, it’s best to seek professional help. Safety should always be a priority, and expert technicians can diagnose and resolve complex electrical issues.

How to Fix the F20 Error Code

In order to fix the F20 error code, follow these steps:

  1. Check the power supply: Ensure that your dryer is receiving a steady power supply. Check if the power cord is securely plugged into the outlet and hasn’t become loose, allowing for a poor connection.
  2. Inspect the control panel: Take a close look at the control panel to ensure that none of the buttons are stuck or malfunctioning. Sometimes, a seemingly minor issue like a stuck button can cause a disruption in communication between the control board and the motor control.
  3. Examine the wiring connections: Shut off the power to your dryer and inspect the wiring connections between the machine control and the motor control. Look for any loose or damaged wires and tighten or replace them as necessary. A loose connection is a common culprit behind the F20 error code.
  4. Reset the control board: In some cases, a simple reset can resolve the F20 error code. Unplug your dryer and wait for a few minutes before plugging it back in. This can help reset the control board and restore communication between the controls.
  5. Contact a professional: If the above steps fail to resolve the F20 error code, it may be time to seek professional help. Contact a qualified technician or a Whirlpool service center to diagnose and repair the issue. They have the expertise and tools necessary to resolve more complex electrical problems that might be causing the communication error.

Please note: If you are not comfortable handling electrical components or troubleshooting your dryer yourself, it’s always recommended to consult a professional to avoid any potential hazards.

Check the water inlet hoses for kinks or blockages, and ensure they are properly connected. Also, make sure the water supply is turned on. If the issue persists, consider contacting a professional technician for further assistance.


The F20 error code on your Whirlpool dryer may signal a communication breakdown, but fear not! By following the troubleshooting steps outlined above, you can likely resolve the issue and have your dryer up and running in no time. Remember to always prioritize safety and, if needed, don’t hesitate to reach out to a professional for assistance. With a little effort and expert guidance, you’ll be able to conquer the F20 error code and enjoy fresh, dry clothes once again.
