What does Error code F06 mean?

hollygau2000 here is what the F06 code stands for

Drive Motor Tachometer Error

The control is unable to properly detect motor speed and the machine will shut down.

If a failure occurs during high-speed spin the door will be unlocked after 3 minutes.

Potential Causes

• Check wire harness connections between the Drive Motor/Tachometer and the

Motor ControlUnit (MCU), and between the MCU and the Central Control Unit

(CCU)

• Check the Drive Motor

• Check the MCU

• Check the Wire Harness

In addition to that make sure that the motor is working properly. It is the motor speed that needs to be tested if it does not work right, the washer will stop. Check the wiring diagram Perform a continuity check of the Drive Motor windings. Remove the connector plug and check across pins 1 to 2, 2 to 3, and 1 to 3. All readings should be approximately 6 ohms.. You do want to make sure that nothing will impede the motor from working properly. Have you downloaded a service manual? It will show you the parts as well as how to deal with errors in detail.

here is more info from here Check the MCU. The connectors are numbered 1 to 3 (L to R). That is, with the MCU installed, connector 1 is on the bottom, followed by 2 in the middle, and 3 on top.

Connector 1 - is the serial communications link between the MCU and CCU and has three wires. At the opposite end, this will be the 2nd connector from the rear on the left-hand side of the CCU.

Connector 2 - is the link between the MCU and the Drive Motor. Pins 1, 2, and 3 on this connector are the Drive Motor windings. Pins 4 and 5 are for the tachometer.

Connector 3 - is the primary power connector. Pins 1 to 2 should read 120VAC with the door in the locked position. Pin 3 is ground. At the opposite end, this is the 4th connector from the right on the front of the CCU. All the connector pins are numbered R to L.

If your continuity readings are normal for the Drive Motor and you have verified all connectors, replace the MCU.

If any of the Drive Motor windings indicate readings higher that 6 ohms, replace the Drive Motor.

Keep in mind sometimes just a simple reset by unplugging your dryer for a few minutes can reset the controls as well.
