Product review (5 stars): We had issues with the washer leaking soapy water. ...
We had issues with the washer leaking soapy water.  Doing some research on the internet showed this happens the dispenser cup is no longer siphoning all of the water and soap as part of the wash cycle.  Then when the rinse cycle starts, the dispenser cup fills with water again and soapy water is added to the rinse water.  This makes the rinse water soapy.  And when this soapy rinse water is combined with the already soapy clothes it creates excess soap foam. This excess foam goes out the overflow vent in the back middle of the washer, and out onto the floor.

The dispenser cup losses the ability to siphon when the seal between the white fill indicator and the shaft fails as pieces start deforming.

To test if have this issue, fill your current dispenser TO THE TOP with water.  It should start draining water out of the drain hole on the bottom, and drain almost all of the water from the dispenser  If not, get this item and your problems will be solved!
