Hello ezideas - First I suggest verifying that there is enough water pressure coming into the unit and that it is at least 120F. Do you noticed if the spray arm will rotate freely or if it is damaged? If so, the spray arm assembly may need to be replaced. Connect with a professional to accurately pinpoint any potentially more serious issue.
Your water pressure is not high enough in the dishwasher to wash the dishes on the top rack. The most common reason is that the pump in your dishwasher cannot pump fast enough to keep the water pressure up. That is because the shaft that drives the pump impeller also drives the macerator cutter that grinds up bits of food fine enough for it to pass through the screen and out to the drain. Over time, small bits of bone, broken glass, eggshell, and other items that are too strong to be cut up by the cutter end up sitting in the area where it has to spin, and they prevent it from spinning fast enough to pump enough water to the top rack with any pressure. It is simple enough to repair. You need to take out the racks, remove the bottom arm and clean out the little macerator. Once that is done, it should work great again.
Hi: I just posted a similar problem, but found a solution. After taking the arm, etc. apart (and verifying no blockages), I thought maybe the lack of water pressure was being caused by the fact that there are TWO holes for the top spray arm (higher and lower rack setting) on my model. ie. that water was being forced out of both holes, causing a drop in water pressure, which was causing the top spray arm to stop spinning. I plugged the unused hole with a wine bottle cork (to keep the water from spraying out the unused hole), and voila, it now works.
the only way you can tell if the upper rack is not getting enough water is to turn a glass right side up in each corner. then run for 2 minutes and see if there is water in each cup. if you still dont get water, then you have checked the pump, the only thing left is that you are not getting enough water into the unit. start the d/w at a normal cycle, let it fill and go into the wash cycle, takes about 3 minutes, then check to see if the water level is just below the heating element. if so then it has to be the wash pump being plugged. if not enough water then you should change the water inlet valve. some times they do get plugged but also make sure you are getting full water pressure to the unit as that could cause not enough water into unit. the faucet under sink could be at fault i have seen valve work but not let enough water in, so dont be surprised if you need a new valve.
I may have the answer. I had what sounded to be the same problem. I found the dishes were dirty after they were cleaned, but I found there may have been a big pot lid blocking the upper arm. I decided to run the machine again, and after a bit opened the dishwasher after to make sure it was not a problem with the arm. Sure enough, the arm wasn't moving. However, I found out on the Frigidaire webpage that some models have an alternating spray cycle, where only one arm spins at any given time. After reading this I checked again, and it had moved by that time. I checked a few times more to confirm this. So it ended up it was an arm blockage after all. Hope this helped...good luck. www.frigidaire.com/support/FAQ-Dishwasher.asp#6
only the top rack isnt getting clean? there is a little plastic
circle in the middle of the bottom of the upper spray arm. turn it
counter clock wise to pull the upper spray arm from the upper rack.
make sure that isnt clogged and the spray holes are not clogged.
the piece that the bottem spray arm plugs into and
runs along the back wall of the tank to the top is called a feed tube.
pull the bottom spray arm out. now you can see the part of the feed
tube that feeds the upper spray arm water. does it pop out freely and
easily? if so then you need a new feed tube, if not then its most
likely your not achieving the right water level or your impeller
connected to your circulation pump(motor) is clogged not supplying
enough water pressure to travel up the feed tube to spin the upper
This could be due to lime deposits from your water or very hard water. If you fill a glass from the sink is it real cloudy? Also it could be due to low pressure from being clogged or if you have galvanized pipes they may be clogging up and causing low water pressure which is not rinsing off the dishes with enough water. To test the water pressure in your house turn one sink on and then turn the other one on. If there is a large drop in pressure this means your pipes may be starting to clog up.
