Upper spray arms not spraying water

All of the water coming to the upper spray arm comes through the feed tube. If the feed tube is blocked or the probe flapper is hung open, water will not flow properly to the upper spray arm. Be sure that when you push in the upper rack the manifold probe is in position in the feed tube. Try adding more water in the tub to see if the upper spray arm starts rotating. Other possibilities; low water charge, cracked spray arm & poor wash pump performance.

A couple of scenarios could cause this problem but the simplest might be the way the dishwasher is loaded. The upper spray arm rotates when water is pumped through the vertical supply tube and into the arm. Make sure that you are not loading the lower rack with items that interfere with the rotation of the upper arm rotor. It might also be a good idea to verify that the feed tube that goes to the spray arm is securely connected to the vertical supply tube.

• Improper loading or over loading of dishes and glass ware that blocks the spray arm from rotating; check your user's guide for proper loading methods.
• the holes in the spray arm can be plugged from food particles or other debris, like coffee grounds; remove the spray arm and clean out the holes; run water through the arm to verify there is no blockage.
• check to see if the spray arm became disconnected from the feed tube or the feed tube from the water inlet feed hose.; reconnect hose or tighten down on hose clamps
• check for any filter blockages; remove food particles and debris
• the tub itself could be under filling, because of a restricted water inlet valve; pour 1 to 2 quarts of water into the tub of the dishwasher and run it; if the performance improves, replace the water inlet valve with a new one; DO NOT try to repair the old valve- it will fail once it's taken apart and put back together.
• the circulating motor drives a water pump that rotates an impeller, which creates water pressure to go through the washer arms and out the holes. The jetting action of the water pressure exiting the spray arm holes propels the arm to spin...if the water pump impeller is worn, damaged, or impeded by food debris, the cleaning action will be greatly diminished; inspect and clean or replace the impeller if necessary.
• If the aforementioned trouble shoot and repair methods do not correct the problem, then a more in depth diagnostic check will have to be done by a qualified repair technician to check switches that controls the water/drain pump, (if it is a dual action model for example); to verify if the switch or the pump itself has failed.

There is a pipe/tube that runs up the back of the inside of your dishwasher. This provides water for the top spray arm. The spray arm has a feeder tube that covers the pipe in the back. If for some reason the feeder tube has come dislodged, the water just drips back down into the dishwasher, never touching your upper shelf. My kids used to jam cutting boards and other large items into the lower shelf and in so doing, would dislodge the upper spray arm feeder tube. Just pull out the upper shelf and check to see that the tube is in the correct position. This should solve the problem.
If not, then the spray arm may have debris in it that keeps the water from being forced through the jets. You'll need to flush the arm with the spray attachment on your kitchen sink. I sometimes use tweezers or a toothpick to dislodge bits of peelings, paper, or bone that manage to get into the sprayer arm.

Cleaning the filter was the right thing to try.
Since you don't see cracks/breaks on the spray arm and it appears that it is spinning freely, I doubt that replacing the spray arm will fix your problem.
If your dishwasher is several years old, your problem is likely a failing pump motor, but before you swap that out, check that the impeller is not damaged. 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.
