My Wife noticed the dishwasher was running a "funny" noise that is not normal to us. I checked everything and noticed that the lower spray arm is wobbly and does make some noise if you spin it with your hand. Is it supposed to be wobby? I tightened it down as much as possible by hand. What part wore out that caused this? Thanks!
