Be sure both wands that spray water will turn. Turn them with your hands.

Almost always you should removed the racks (may be a little hard to learn how to do this) and investigage what is happening. You may have a knife or fork stuck in the impeller keeping it from turning.

Another thing to look for is how much water is inside. Start your dishwasher and stop it after it sounds like it is full of water. Check the depth... should be about 2 or 3 inches... if not there is a float that determines when the water is full... it is usually in the left front... be sure it is not blocked in some way.

Clean the sediment buildup in the pump. You do this by running a cycle of 3 cups of white vinegar. Without dishes, let the dishwasher fill... then add the vinegar. Go through a complete cycle (without heated drying). Then run it twice again through normal cycles without the vinegar.
hope this will work for you

How do i remove the bottom center piece that the spray arm came out of?

The arm spins on a tube that is held by a round screw that should only be finger tight. That tube is screwed into a boss on the bottom of the dishwasher. You can do two things.
1. remove the whole lot and then unscrew the top screw by holding the tube with grips and another set of grips on the top screw.

2. Tighten the screw on top until it becomes firm, and then unscrew it.

If the dishes are not coming clean it may be that the jets in the spray bar are clogged with fluff and debris.

Dishes on top shelf not getting clean

Check your upper wash arm.... check the holes, especially the ones at the end of the arm. Are they possibly clogged with debris or hard water? This is the usual cause of dishes on the top rack not getting clean. The holes at the end of the wash arm are angled to eject the water at an angle to use the reaction to push the wash arm around. If those holes are clogged, then the arm won't rotate, and only those few dishes or glasses right under the arm will get clean, and the remaining 80% of the dishes on the upper rack won't get clean!

Kenmore 3380957 rev a won't get dishes clean

Make sure that that upper arm is free to turn. Check it while you have dished installed, because sometimes, dishes on the lower rack may stick up too high and hit it. Otherwise, check the back of the water-supply tube attached to that upper rack.... Is it lining up with the water feed port or hole at the backof the dishwasher? Is there a gasket that is either ripped or missing? And check that wash arm carefully.... Might it be split or bent? Are the holes on the bottom clear? (Those holes are usually angled to push the arm around; if they are clogged, the arm won't rotate.)

I have a KitchenAid Dishwasher Model KUDT03FTSS0. I am having a problem with the glasses on the top rack not being fully cleaned. There seems to be an amount of residue left on the glasses. I have...

Check that the arms spin freely when spun by hand, then check the outlet jets at the trailing end of the arms are not blocked with food particles and other solid matter. This often happens and the arm is unable to turn because the water jet that is supposed to drive the arm does not have the force to rotate it with the result is that the upper dishes do not get enough water and chemicals. It may also cause water to continue dripping onto dried dishes after the the drying cycle has stopped.

The top rack of dishes are not getting clean. I

you need to check the upper wash arm for blockage from debris,if this is not the case,then you need to replace the water conduit from the lower sump area to the top arm,after time the water erodes the plastic conduit especially where it connects at the arms and water gets by these areas and can no longer build pressure to spin the wash arm

Not cleaning dishes on top rack

Check that the top arm rotates (you will have to open the door a couple of times during the cycle). If not remove and ensure the nozzles are clean. Replace the seals, particularly the one where the arm slides in when the top drawer is pushed home. Worked for me

Top row of dishes are not getting clean.

It sounds as if there is no water pressure to the upper arm. You may want to try putting something over one of the holes to see if it is disturbed during th wash cycle. There should be enough pressure there to blow off a piece of masking tape if it is not attached too securely. Do some experimenting to see if you have presure there. There could be a problem with the tube that feeds to the water to the upper arm.
