My 10 yr old dishwasher was not cleaning correctly. I cleaned out my old dishwasher arms and found so much debris. Plastic wrappers that didn't dissolve, powder that didn't dissolve, and seeds from various fruits and vegetables. After the second cleaning, I looked at the price of new arms. WAY less expensive than I thought. Easy to replace the spray arms. Definitely worth changing the arms out on a 10 year old machine than getting a new machine or to keep cleaning them. I now use liquid cleaner and my machine cleans as if it were brand new.Did not come with attachment screw, came with washer arm only and did not work with screw from old washer arm. Thought it came with screw and arm, full assembly, but no luck. No bueno.Dishwasher not cleaning the dishes well anymore? Replace all the arms and you’ll cry with joy! I couldn’t be happier. My old ones were full of eggshells and paper and glass. Now I actually have clean dishes at the end of a cycle. Happy happy happy.Glad I was able to find these replacement parts for our 8 year old dishwasher - did the trick, and seems like they improved the design as well.This part works great, and easy to install, even for an old lady. I put it in myself. Shipping was super fast also.Works great. Pretty much had to gut our dishwasher and put in all new parts and it cleans better now than when it was new.Right part. Arrived on time and in new condition. Fixed my dishwasher easily with this.help my dish washer clean betterMade my dishwasher brand new again. The price is outrageously cheap compared to driving to local competition. I honestly expected less. Cheers, use my clean glass
