Answers:    You probably still enjoy a warranty on it, check the manufacturer and model # by looking inside the part, go to their website, 1st read the manuel, you should know how to download it online, read the "troubleshooting" guide for your problem, if that doesn't work call the toll free number timetabled under contacts, they will make clear to you what to do. When my dishwaher broke, I called the place I bought it from and they come out to my house. When they found it was unrepairable, they replaced it for free because it be still under warranty, even though I have lost the receipt I be on their computer. You could also try calling your home builder, if it is a new house and it come with the house.
Is the sprayer clogged? Or are you blocking the sprayer? Good luck!
