THE SPRAY ARM IS CLOGGED.

YOUR FILTER IN THE BOTTOM IS CLOGGED.

THE TUBE THAT FEEDS IS HAS A BREAK GOING UP THE BACK WALL.

LACK OF WATER. ADD WATER SEE IF THAT WORKS. THEN YOU WILL NEED A VALVE.

THE SPRAY ARM TUBE IS NOT GOING INTO THE BACK OF THE FEED TUBE.

Why is the top spray arm not turning


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.

Why doesn't upper spray arm function properly?


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.

Upper spray arm


Hello Alan - Will the spray arm rotate freely or is it damaged? If so, you might have to remove and replace the spray arm assemblies. The top spray arm typically starts to function when the unit is in rinse or wash cycle. If for some reason the top rack is not getting clean, there is a possibility that it is not working properly. The top spray arm is either blocked by pots/pans or not enough water pressure is being pump meaning that the flow of water is not making it to the upper spray arm. If you tap the delivery tube that feeds this nozzle and the water pressure jumps immediately, then the problem may lie with a faulty pump or impeller. Should all basic troubleshooting measures fail contact a certified technician to narrow down the precise issue before investing in parts that may or may not be the root cause.

Top spray arm does not spin


The upper spray arm is powered by water from a tube that runs up the back of your machine on the inside. If the connection is not aligned, then the water can't get to the spray arm. My children use to knock mine out of kilter when they loaded the lower section. It's easy to see if the supports are not attached to the upper rack and a simple snap will get them back in place.
It may also be that the spray arm jets are clogged.Depending on the model, the upper spray arm generally has a nut or thumb/butterfly screw (plastic) that you remove and then remove the arm. I always soak mine in hot soapy water and then flush with hot water. If debris such as pieces of paper, bone, peelings are in there, you'll need to take a tweezer or toothpick to remove them from the jets. The upper spray arm usually has the same apparatus and you can follow the same procedure..
I hope these suggestions help your problem. If so please come back to Fixya and rate my advice!

Top rack does not wash dishes.


Possible causes of spray arm inefficiency:
Loading large or tall items in the lower basket which stops the arm revolving.
Upper spray arm split along seam.
Upper spray arm blocked.
Under dosing of powder causing foam and reducing upper spray arm water pressure.
Blocked strainers reducing water to circulating pump, therefore reducing upper spray arm water pressure.
inefficient wash motor impellor (faulty)

Lower spray arm siemens aquastop dishwasher doesn't rotate


Sprayers require water to pass through the jets to provide motion to the arms.

Suggestion;

Remove the sprayer from the machine and look for blockages. (Removal should be easy, at it is expected that the user will need to clean the jets occasionally; If you have any problems removing it, consult your manual).

Upper spray arm on dishwasher does not move


you most likely have gunk inside the arm or holes not allowing the water to spray out and turn the arm. Otherwise, the arm bearing may be stuck and will need a gentle push to loosen up.
