If is clean dishes in the upper basket, I conclude that the pump produces enough pressure what means that the lower spray arm for some reason does not rotate and because that washing result is bad. Before washing I would check the lower spray arm rotates freely and after that open the door during washing and check if the lower spray arm rotates. Sometimes, the holes in the spray arm clog and disable turning which leads to poor washing results in the lower basket.
Carefully inspect the lower spray arm for a crack or separation. Also inspect the holes in the spray arm that may be stopped up with debris. Remove and clean the filter in the front center of the tub. Set the spray arm at the 12 o'clock position and start the washer. After 30 seconds open the door and check the position of the spray arm. Do thi several times to confirm the spray arm is rotating.
Probably blocked spray arms is the cause of the unit not cleaning properly or rotating. Remove each spray arm (there are 3 in total) and check and clean all the holes as this is where the water sprays out from to clean the dishes and glasses. When they are blocked you get poor wash results.
Yes it can get plugged. Any debris pumped up to the arm can get lodged into the tiny holes. Also, sometimes the arm itself becomes split along the joint between the lower and upper half. Remove the arm to inspect, clean, and repair/replace the arm if split. I fixed our Maytag spray arm when it split, by drilling a series of small holes along the split parts and sewing the thing back together with fairly fine copper wire. Still working great after a number of years. The small spray holes can be poked clean with a heavy needle and the arm vacuumed out. If after all this it still won't spray properly, the intake screen at the bottom of the lower spray arm tower may need to be cleaned as well. Remove components starting with the spray arm and work your way down, noting placement and orientation of each piece. Remove the screen, and soak it in hot water, detergent and white vinegar for an hour or so. Check all holes in the deck for any food plugging. Reassemble in reverse order and check the lower spray arm for plugging as well. Hope some of this helps!
Check the upper spray arm for debris plugging the spray holes, if clean then pull off lower spray arm and filter screen, and clean and remove any debris found in the sump, check the disposal blades as well. You will need a torx style screwdriver to remove the sump screen on this unit. You can buy a set for under $10 at your local hardware store.
I assume you are having spray issues, or a grinding noise. If odor is your issue, go to the bottom of the message.
For the dishwasher pictured above, Open the door. Remove the lower rack.
Push in the tabs holding the upper basket rail end caps and slide the caps up and out. Remove the upper rack. Clean the holes in the upper (or middle) spray arm.
Hold the lower spray arm still and rotote the thumb tab clockwise. Remove the lower spray arm. Clean the holes in the lower spray arm.
Use a small flat screwdriver to release the tabs holding the upper spray tube from the dishwasher inner wall and ceiling. Rotate the spray tube to the right and remove the tube.
Using a # 20 Torx bit, remove the (about 10) small screws holding in the top of the sump assembly. Remove the top section with the fingers all around it.
Using a # 15 Torx bit, remove the screw holding the round cover over the pump suction. Remove the cover (grab the tab sticking off the corner with a pliers and pull up.)
Anything stuck in the sump will now be visible. If the screen is completely clogged up, then the blade isn't wiping the screen clean. In this case, the screen should be replaced.
The screen is removable, but difficult to re-install. If you need to re-place it, put an open end wrench between the screen and the rotating blade to hold the spring compressed. Also, notice the screen isn't round. The flat edges fit only in the slots they came from.
If it's odor or white powder you want to clean out, use a dishwasher cleaning product such as Dishwasher Magic.
I tell every dishwasher customer: "You do not need to rinse your dishes before washing. But you do need to scrape them off."
metal sleeves at the end of the lower spray arm?? dont remove them they only protect from hitting against heate and melting. should be a center thumbscrew in spray arm loosen that nut and should come right out, pokin with wire or toothpik willwill clear joles but you gotta remoe the debris from the arm other wise first run will shoot right back nto holes
