The middle sprayer sheared off our GE Power 3 dishwasher, ruining the hub in the process. We removed the rack from the dishwasher to make it easier to access the sprayer hub, otherwise it's awkward. The biggest challenge was finding the right tool in our garage (we used a 1/4" wrench as we did not have the right socket size). Once the screw was removed, it was quite easy to remove the hub and attach the new one. The rest was simply attaching the new sprayer to the hub using the included washer and screw and putting the rack back in the dishwasher. It took about ten minutes. The video on the appliancepartspro.com website was very helpful. Unless you simply don't want to bother with It, there's really no reason not to do this yourself and save some money.
