James L Los Angeles , CA August 15, 2014 Appliance: Whirlpool Washer WTW6600SB2 Whirlpool Washer Wtw6600sb2: Whirlpool cabrio washing machine had f50 error code would not spin or agitate. How to replace Control Board. Did test 3. I first replaced the stator because there were cracks in the plastic. Still error F50. Replaced the wiring harness and the sensor and top plate because it only comes in a kit and the connection to the sensor had changed so you have to use the kit and change it all out. Spent many hours taking this machine apart and checking connections and testing and retesting... still F50 error code. Changed out the control board next... took all of 10 min, woo-hoo!! it worked. It's not worth my time to switch back the kit and return it and the stator was cracked in four places anyway, I had already replaced the bearing and seal two months earlier so I hope it will be trouble free for many years now. I would say that the hardest part in the repair was having to remove the one elbow hose to get the wiring harness out and new one in through the correct way...have something to catch the water. I hate that type of clamp and it is a challenge to do it even with channel lock pliers. Make sure you have it back together correctly or it will leak.
