Old spray arm was plugged up with build up.
Pull straight down to remove upper arm. Hold new arm in place and push the locking retainer into the center hole in the arm and locking it into the holder. Very simple.

Upper Spray Arm replacement
popped out the spray arm snap retainer that held in the upper spray arm and pushed the new snap retainer into the new upper spray arm to complete the job. I thought I must have done something wrong because it only took about a minute.

Dishwasher not cleaning dishes
Lower Dishrack assembly just rolled into the dishwasher-easy, easy, easy!
The Upper Spray Arm assembly- broke off tab to old arm using a screwdriver to pry off the tab. Pushed the new arm assembly and tab into place. The only problem was not to bend the prongs on the plastic tab (they bend back easily if you do happen to bend them, though)
My dishwasher cleans like new!!

Spray holes clogged by hard water deposits
I took off old upper spray arm by gently prying it and the retainer off the upper section of the dishwasher. When I first did this, two prongs of the original retainer clip broke off so I had to order a new retainer clip. The new arm fit perfectly in place and was easily held in place by the new retainer clip. This is a very simple and easy repair. The only tool I used was a flat headed screwdriver to pry off the old arm, but one could probably pry it off manually also.
