6 out of 6 people found this instruction helpful

I first removed the washer arm. Be careful because it is screwed on with the large center plastic piece with right hand thread. That allowed me to take the arm and disc off.

Next I took 6 screws loose with the allen wrench. This allowed me to get to the filter ring. I removed it and that allowed me to get to the three screws holding the discharge. I used a 5/16th socket to remove them.

A plastic disc that was part of the upper pump came loose and caused the noise. I replaced the upper discharge housing (with upper pump as part of it) and upper discharge housing gasket and reversed the order to reassemble.

The exploded diagram was a terrific help
