How to Troubleshoot & Replace Ge AP3875619 / WD22X10047 Dishwasher Lower Spray Arm

I replaced all the arms -- which I ordered from AppliancePartsPros.com. These parts arrived very quickly. Thanks. 

I ordered three new spray arms plus two rack slide end caps. Installed all in just 10 minutes, and yay! We have a dishwasher that cleans like it was new. 

Remove middle spray arm with a screwdriver/ Remove lower assembly with a quick lift and counter clockwise turn 

Your videos on how to change the spray arms were so informative and the part pictures helped me find the right part even though I didn't have a part # at first. I ordered the parts and fixed my own dishwasher by myself. I am a grandmother aged 59 with by focals and bad hips. If I can do it, so can you! So happy I didn't have to pay a repair man or buy a new dishwasher, neither being in my budget for now. 

Upper and lower spray arms were clogged with food and debris and they were not worth the time and labor to clean. So I replaced them and the fine filter. 

Orderd all three spray arms. Replacements arrived very quickly. Reviewed installation videos & went to work. Done in about 1/2 hour. A piece of cake. Thanks for all your help. Jay 

Ordered new utensil caddy and new top and bottom spray arms, took about 5 mi Utes to replace and now the dishwasher is cleaning like new 

Bought a new lower spray arm. Spun it into place. 

Purchased replacement part from AppliancePartsPros. Took minutes to install, dishes are clean, I'm happy. 

Replaced with 2 new ones
