I am Just another frustrated dishwaser owner also. I also have a fridgidaire about 4 to5 years old. My middle arm does not spin. I triped the door with a knife and ran it though the cycles. Check so often to see what it is doing. First for you try cleanning all your fillters, they snp out or unscrew depending witch part you want to clean. It is amazing how much junk you'll find. Take it all apart. At the bottom after you take one filter out, take the next one out. Also I cleaned mine with a CLR or simmilar product to make sure my inside pipes were'nt caroadded. A suggestion a recepionist from a repair store gave me. Let me know what happens. Chris Chrsi-bernacchi@sbcglobal.net
