Hello. I have a WFW9500TW02 washer and am getting the F70 and F71 codes intermittently. Sometimes turning off the machine and turning it back on allows for normal operation, but these codes keep recurring. I have run the diagnostic per the instructions from the tech sheet of a WFW9500TW01 washer that I found on this forum (Thanks, Jake!). The test completed with no errors being reported. I am wondering if there is a specific tech sheet / manual online that I can find for my specific washer.
From my reading of various forums for similar washers, it sounds like the problem is either in the MCU, the CCU (AP4343491), or the UIC (AP4538151). I am assuming that since the diagnostic tests ran with no errors that the MCU is okay. And, my drum is rotating freely which, based on a post from another forum, leads me to believe that I need to replace the UIC. I have found a few websites that sell this part, but I cannot find any instructions on how to do complete this repair.
However, since nothing that I have found/read is specifically for the WFW9500TW02, I am hesitant to buy parts and try these repairs.
Any assistance would be much appreciated.
