I have experienced the same diverter motor leaking problems. I have the whirlpool gold with the diverter motor (w10155344). I bought the unit new 4 years ago. The fix is remove the the two screws that hold the diverter motor and pull the motor. You will find why its leaking is because the rubber seal was installed up side down from the factory. The seal and motor should have calcium and corrosion build up from all leaking. No need to buy new parts. Clean the rubber seal with CLR very carefully, as you will notice a deep groove that has a spring around the inner part, use a tooth pick to clean the corrosion out of the deep groove. After a thorough cleaning, apply thoroughly with vaseline for rubber velocity, be sure to wipe off excessive vaseline. The diverter motor can be cleaned by separating the clips with out breaking tabs that hold it together, be sure to clean the corrosion off the wire connection and the little board it connects to on motor. When installing the seal, slide it down the motor shaft with the deep groove face down it should slide into the lip at the bottom and seat nicely, be sure to clean that area as well with CLR. Install the motor, be sure to clean with CLR where the shaft goes into the hole. That took care of the problem for me. Thanks.
