Gayla S Wadesville , IN March 12, 2014 Appliance: Whirlpool Washer GHW9400PW1 Whirlpool Washer Ghw9400pw1: Flashing F06 error code. How to replace Control Board. We ordered our part from AppliancePartsPros.com and watched the attached video on how to install. I placed the order and it arrived in TWO DAYS!! Shipping was very reasonable! We saved $170 doing it ourselves! The video was nothing fancy but easy to understand. My washer has been working perfectly so far! 11 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
