Hello all. Great forum! I did some searching and couldn't find an exact solution for what my dishwasher is doing. (or not doing!). About 2 weeks ago I noticed the dishwasher was making a weird noise and had a lot of water in the bottom and not getting the dishes clean. I checked out the waste hose at the garbage disposal and saw that it wasn't shooting water out anymore at all. I pulled the dishwasher out and found that the waste hose at the bottom of the dishwasher had kinked and was probably only letting 10-20% of the water out. There was also a bunch of solid grease in the hose where the kink was. At that point I put a shorter hose in, cleaned out that grease and then I looked at the 5/8" hose going towards the disposal and it had a bunch of solid grease in it too. I took the 5/8" waste hose outside and ran hose water through it and I bet 2 feet of solid grease came out of the hose! At that point I put it all back together and the dishwasher worked great other than the glasses and dishes on the upper rack are getting food particles on the top and not getting as clean as they had done before. Then I checked and the upper spray arm never moved throughout the whole cycle. I see that there is a tube that goes from the bottom of the dishwasher to the top that makes the upper spray arm move but when I watched the dishwasher throughout the whole cycle, I would see water go up the tube on the side from time to time, but the water would just get to the top of the dishwasher, sit there, and then drain back down later. It never seemed to have enough force to make the upper arm move. I looked at the repair manual here and saw about how there is a check ball that controls where the water goes so I took the basket/pump assembly apart to look for more possible grease or food blocking something but it actually looked pretty good down there. Any ideas? Is the pump bad not putting enough pressure out? Any help would be appreciated.
