Upper spray arm is not turning and I don't think water is coming out. Dishes on top are not coming clean. Dishes on bottom are clean (as clean as they get with this dishwasher). How do I remove upper spray arm. Also I'm not sure how to remove lower dish rack to access upper spray arm. Any help appreicated. Kitchenaid model KUDP01FLSS5 Chris

If there is no blockage, your pump may need to be rebuilt or replaced. If your machine uses a solenoid valve to control weather the pump is washing or draining. The drain valve may be stuck somewhat open, diverting wash water down the drain. Or the wash valve may be not opening fully. Different machines work in different ways.

Hello, check the sprayer arm on the top of the dishwasher inside and to see if it spins. Don't block this spray arm with glasses or dishes that could block the operation of this sprayer cleaning arm.

Now, if it not spinning, check out the fitting arount hing bolt. If this wore out then you will have water pressure lose. Replace if need be. Also, check the feeder water spout that runs the upper spray army, it could be pluged. GB...stewbsion

Possible that the motor impeller has good particles in it, causing poor water pressure, which would be most evident on the top rack. You would have to remove the spray arm, then the filter, then the torx screws to get at impeller....unfortunately, that model of dishwasher isn't the greatest in the first place for washing, since it only has the one spray arm.

Hey- Two things could be wrong.- clog, or bad motor. Sump screen needs to be cleaned of debris. Removal of sump cover to access screen requires torx bits and some patience. Replacement of pump requires pulling out dishwasher to access bottom. Motors fail when seal between motor and pump fails. Will still operate, but become weaker over time. Parts available- motor about 100$ at appliance parts pros.appliancepartspros. Hopes this helps- Thanks- ED

maybe not... if unit is incorporating more than one spray arm,chances are the upper spray arm is not getting water.pull top rack forward,gaze under top rack near rear manifold.slowly push rack back in.notice if manifold inserts into upper wash feed.if so,possible motor issue. if not,bingo was his name-o!

Make sure you get water to the dishwasher. Check to see if the water shut-off valve (located under the sink) is open. If you get water to the dishwasher, but there is still no water inside during the fill cycle, the problem might be with a faulty water valve (located at the bottom of the dishwasher, behind the kick panel, on either side), in which case replace the water valve.

If there is not enough water, the dishes would not get cleaned. This could be caused by a partially closed water shut-off valve (located under the sink), or a faulty dishwasher water valve (located at the bottom of the dishwasher, behind the kick panel, on either side).

There is usually two, sometimes three spray arms in a dishwasher. Make sure there is no debris blocking the holes inside each spray arm.

The broken bottom arm is probably preventing any water / water under pressure to get to the upper arm.
After you replace the lower arm, you should have much better cleaning in the top shelf.
While you are in there replacing the lower arm, recommend you remove the filter under it and clean the filter and any debris you find. Be careful of broken glass!
Good Luck!

There is a screen that you can remove from the sump of the dishwasher to clean. Just twist it to the left and pull it out. I have some tips that you might want to check out if this does not resolve your problem.

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. otherwise....

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 spray arm.

Run the dishwasher and observe the spray arm,if split it will spray water down: Also check water in tub, is it filling up sufficiently to get near the heater? If it has a upper spray arm does it spray water? If not you may have a clogged upper spray arm.
