having the same problem with a WFC7500 it took a while to coax the code out of the washer but i got it.checked the pump it was ok, ran a diagnostic on it the motor spun the washer at the high speed but in the operating cycles the motor wont reach high speed and shuts the machine off at 13 minutes like it finished the cycle,and it says END.I am now pulling the MCU and finding some damage so its off to be rebuilt
