Answer Andy, Before you replace the control board, you need to check the optical sensor WPW10705575 and make sure there are no suds developping in the tub from the rinse agent, or detergent. If the sensor does not produce the correct readings to the control board, it will conduct an "APF" cycle, until the sensor is satisfied. You can remove the sensor from the bottom of the pump housing and check for deposits that may have built up on it. Thanks and Good Luck Read More...
