The F01 error code on a Whirlpool Duet Dryer indicates a primary control failure. This error is triggered when the main control board of the dryer detects an issue within its electronic components. The control board is responsible for managing various dryer functions, and a failure here can prevent the dryer from operating properly.

When the F01 error appears, it usually means that the control board cannot communicate with other parts of the dryer or process signals correctly, leading to a halt in operation. This error is generally accompanied by a flashing F01 code on the dryer's display, alerting users to the problem.

To attempt clearing the F01 error, unplug the dryer from the power source for at least one minute. After plugging it back in, try running a cycle to see if the error persists. If the error code reappears, it suggests a persistent issue with the control board. For further troubleshooting and repair steps, please refer to our repair guide linked below.
