1) Lower Spray Arm and Pump Housing Filter:
1a) Unscrewed lower spray arm cap. Removed lower spray arm. Removed metal radiant shields from lower spray arm, cleaned them, and snapped them onto the new lower spray arm.
1b) Removed Torx screws from pump cover, then removed pump cover.
1c) Curled new filter into circular shape, interlocking the tabs to connect the ends together, then replaced the old pump housing filter by removing the old filter and then pushing the new one into place in the pump cover. Old O-ring was fine, so didn't really need to replace it.
1d) Re-installed pump cover by aligning the water ports on the cover with those in the dishwasher, then pushing cover down into place, then installing and tightening the Torx screws. If I were to do this repair again, I would replace the pump cover with a new one.
1e) Installed the spray arm by placing the new lower spray arm into position over pump cover, then screwing in the lower spray arm cap.
2) Upper Spray Arm
2a) Removed upper spray arm by unscrewing the snap outlet nut, then removing the spray arm retainer. This way, the retainer is undamaged and can be re-used.
2b) Attached new upper spray arm to snap outlet nut by pushing old retainer through new upper spray arm and into snap outlet nut.
2c) Installed new upper spray arm by screwing snap outlet nut back into the dishwasher.
