Hello,

I have a whirlpool GHW9400PL4 and am experiancing a problem that I believe is related to the motor/control boards.

Whenever I run a cycle, when I reach a spin cycle the machine will stop and display the error code F06. I have checked the connections related to the motor, and all seemed clean except for at the wiring harness at the motor. I cleaned some oxidation from these conections with sandpaper, and sprayed the connections with some WD40. The washer worked fine for 2 weeks afterwards. Now when reaching a spin cycle the time remaining flashes, the washer attempts to resume its cycle. After a couple of repititions of flashing and resuming, the error code F06 appears again.

One other detail - I can run the system through the full set of diagnostic tests without any issues with the motor spinning. Also, I can occasionally get the machine to run a full cycle if I unplug it for a couple of hours and try again. At this point I am leaning towards the issue being control board related - does that sound right?

Any suggestions? Do I need to do a better job of cleaning the electrical contacts at the motor wiring harness? Is it another problem, like the MCU? Any help would be greatly appreciated!

Hi.

Use the tech sheet to check the motor and motor control.Replace the motor harness Part number: W10137867

Here are the breakdown diagrams and Pump and Motor parts for Whirlpool GHW9400PL4 - AppliancePartsPros.com

Post the results.

I have checked the resistances across the motor pins at the wiring harness. The resistance across Pins 1-2, 1-3 and 2-3 are all 6 ohms, and the resistance across Pins 4-5 is 118 ohms.

I have ordered the wiring harness - when it is in I will replace it and see if that works.

Is there anything else I should be testing while waiting for the part to arrive?

Hi.

You may order the MCU also. It can be return if you don't need it (even if you install it).

hey there, I'm just wondering if the wiring harness fixed the issue? I'm experiencing a similar issue here. I will pull the harness out and check the connections later.
