Two other things to try. First, check the air dome and hose on the lower right rear side of the outer tub for gunk buildup. When the tub fills/drains water, air pressure in the hose is used to operate a pressure transducer on the main control board which tells the computer how much water is in the tub. This transducer is much more sensitive than the typical pressure switch found on other washers. Also try running the calibrate function in service mode. Another remote possibility is something caught in the pump. The control board monitors electric current used by the pump and if something is caught in there, it thinks there is still water in the tub even though the pressure transducer says there isn't.

Eric I had the pump off and checked it, nothing stuck, runs fine. Blew out hose to make sure it was clear. Ran the calibrate function each time I checked, removed and replaced component and everytime the washer stops at the same spot. It runs through everything - water fill, agitate, drain, and then when it gets to spin, you can hear the shifter change and the drum starts to spin but then stops and lid light flashes and machine needs to be unplugged to reset. Another question: on your parts sight there are two different elect. control boards. One is $376.77 part#W10393489 and the other is $144.19 part #W10480261. The higher priced one is for model #'s wtw4950xw0 and wtw4950xw1, and the lower priced one is for model #wtw4950xw2. My model is wtw4950xw, there is no number after the w. How do I know which part I would need.

Are you able to rotate the basket freely by hand? I can only assume that yours is the xw0 version. The last number in the model number reflects any revisions made to previous models. I don't know why the discrepency in price and don't know if the later version control unit would work in an earlier revision washer. It's does the same thing but may have hardware/firmware upgrades. You might try contacting Whirlpool if no other input on the issue here. Here's the parts manual for the xw0 It has a different number altogether for the control unit but crosses to W10393489 Eric

Ok, that's normal. Just checking to make sure the basket isn't locked up. Looks like the control board.

Eric Yes, I think so. Disappointed, only had it for a year. Thanks again

Based on feedback from other technicians, it is becoming apparent that even though the shift actuator passes all tests indicating it is good, replacing them anyway, fixes the problem. Something with the optical rpm sensors.
