Question about Kenmore Elite 45986 Front Load Washer

1 Answer

F6 & Won't Spin

I have followed all suggestions for my Whirlpool Duet for the F6 error. All connections are perfect, no leaks, etc. I have come to the conclusion it is the Motor Tachometer. What does it look like and where is it located?

Thanks!

The error is an indication a motor speed problem. You will need to check the following:

- Check the wiring harness. Verify all connections between the Drive Motor, Motor Control Unit (MCU), and Central Control Unit (CCU).

NOTE: The MCU is a circuit board located in the vicinity of the Drive Motor on the bottom rear of the washer. To access the MCU, you will need to remove the back panel of the washer.

NOTE: The CCU is the main computer for the washer and is located behind the wash tub. You will need to remove the top panel to access the CCU. This is accomplished by removing the three screws in the back of the washer that hold the top in place. Once the screws are removed, the top panel will slide back, then lift off.

- Check the Drive Motor. 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. HINT: You can also take this reading by removing connector 2 from the MCU and measuring across pins 1, 2 and 3. If the readings are good, this will also prove the wiring and connector good.

- 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.

NOTE: 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.

What does and F6 error code mean on a whirlpool duette front loading washing machine mean and how do I fix it?


Error code F06 means 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
1/ Check wire harness connections between the Drive Motor/Tachometer and the Motor ControlUnit (MCU), and between the MCU and the Central Control Unit (CCU)
2/ Check the Drive Motor
3/ Check the MCU
4/ Check the Wire Harness
Replace failed component or contact an authorized repair agent.

Washer comes up with error f6


The F6 error on a Whirlpool Duet means that the control unit doesn't know the drum RPM speed during the spin cycle. It occurs with a number of problems. The problem could be with the MCU (motor control unit) or the wiring between the motor and the MCU. Next you should check the wiring between the MCU and the CCU (main clock). A problem with the door lock or that wiring could also cause the issue. Finally, the bearing on which the drum spins is bad.

The MCU is the most likely faulty part unless you find a wiring problem. (The wiring harness has a number of small wires connected to it; it's not uncommon for one wire in the group to break while the rest are intact.) Inside the washer's front panel, there should be a wiring diagram with additional information on some diagnostic steps.

If you can't easily spin the drum by hand, then the bearing is a likely suspect.

I hope this helps.

THE F6 MEANS THE CONTROL IS NOT GETTING A READING FROM THE TACHOMETER ON THE MOTOR. CHECK THE CONNECTIONS FROM THE MOTOR TO THE MOTOR CONTROLLER,(THE CONTROL BOARD MOUNTED TO THE BASE).

"F02" is a Long Drain error. If the drain time exceeds 8 minutes this error code will be displayed. In addition, a "SUDS" error may also be generated as a secondary error. This is an indication of a drain pump problem and/or clog in the drain line. You will need to check the following:

1. Check the drain hose to make sure it is not kinked or clogged.
2. Check the electrical connections to the pump and ensure the pump is running.
3. Remove the drain pump filter and check for foreign objects and/or debris.

To check the drain pump, click on the following link for step-by-step instructions.

If the above procedures do not correct the problem, it is recommended by the manufacturer to replace the drain pump

Not spinning


The following link explains the "F06" error:

http://www.fixya.com/support/r714929-f06_error_whirlpool_duet_kenmore_elite

It is known as a Motor Speed error. More commonly the motor control unit (MCU) fails. However, you will need to check the drive motor, belt, and Central Control Unit (CCU) to be sure. I hope this helps you.
