Small plastic top and mid spray arm do not turn, bottom does
I replaced all three rings(gaskets, seals) on both upper and lower spray arms as well as the top plastic spinner. I poured CLR into tub to remove hard water build up. I checked to see the spin, but only bottom spray arm spun before and after changing parts. (I over rode the door's relay to peek inside.)I reremoved lower spray arm and checked the amount of water pumping up. It appeared to go up about 6 inches. Is this enough water pressure from the pump to turn the top arm. Water comes out of top spray arm weak, not strong enough to spin it. What next, I already have over $50 in parts?

Decrete, you want to get down to the chopper and screen. If the screen is plugged up with gunk there won't be enough pressure to reach the top spray arms. Check out the posted pics. Remove the lower spray arm. Rotate the rear feed arm to the right until it unsnaps from the tube going up the back. See the 4 torq screws holding the filter on. Remove them. Lift the filter up. Now you will see the chopper inlet cover. 1 torq screw holding it in. Lift it up and there's the chopper and screen. Catriver..post back

Remove the upper wash arm from the rack. Examine thoroughly. Look for hair line cracks especially if the wash arm is plastic. Top rack wash arms have spray holes on the top AND bottom. Check both places. Sometimes small fish bones will clog the hallway of wash arm not just the holes. After years of use, the wash arm will bow especially plastic ones. Be sure the water connection to wash arm is Secure. If you think the wash arm is not spinning, try this. Place a old cell phone inside a sealed glass jar and start recording video from the lower rack. Be sure jar is Secure. The light from phone will come on. You might see the problem this way.
Have you checked the seal/gasket on back of the upper spray arm assembly?
If you pull the upper basket forward the entire spray arm assemble will come with it. You can remove the spray arm assembly by releasing the single clip at the top at the rear of the basket. The spray arm assembly with then slide out backwards.
Once you've removed it, have a look at the back of it. There is a plastic gasket inside with 2 holes which fit over the studs at the top of the delivery tube still attached to the back of the dishwasher.
You can remove the back cover of the spray arm assembly by releasing the 2 clips at the top and bottom. Be careful here as they may be brittle after prolonged use of the washer.
Remove the back cover and take the plastic gasket out. Place the holes of the plastic gasket over the studs on the delivery arm in the back of the washer and check the gap between the gasket holes and the studs and check for excess movement.
If there is a significant gap or movement here, then it needs to be replaced. If there isn't a reasonable seal at this location, water will leak from there and there may not be enough pressure to rotate the spray arm
If you've already done this or there seems to be no problem with the gasket, please let me know and I will try to assist you further. Similarly, if this proves to be the problem and you need assistance obtaining replacement part/s, just let me know.
The ring fits just under the spray arm and the split is normal. When you tore the spray assembly apart, did you clean the screens at the bottom (if white hard-water deposit, soak in 50:50 hot water and white vinegar)? Make sure none of the ports in the deck are plugged with food deposits. Check both spray arms for plugged spray holes or split seams. The upper arm moves from water pressure alone--no motor. Make sure it spins freely by hand. We had to try different detergents to get away from a gritty deposit on glassware. Did you fix the leaking problem? Inspect the gasket seal around the door for damage or hardness and check the latch for holding the door closed firmly. Hope some of this helps!
The spray arm turns when water is forced through the small holes in the arm. You may need to tear the lower spray arm assembly down to the deck, looking for split or warped plastic parts including the arm itself. There is a large screen at the bottom that becomes plugged with water and food deposits--soak/wash it in hot water, white vinegar, and detergent. Check all of the openings in the deck for food plugging. Reassemble in exact reverse order. Check the upper arm for plugging and possible seam splitting as well. Make sure that all of the small holes in both arms are open. Hope this helps!
Easy to solve!
(1) Remove the drawers to give yourself room to work
(a) bottom drawer just comes right out -- but you knew that
(b) Carefully unclip small plastic retainer caps at the ends of the metal "glides" for the top drawer. Then slide the caps out of the glides. Then remove the top drawer.
(2) Unscrew the "gear-like" plastic fitting into whose hole you were sticking your finger when you felt that small cylindrical ring.
(3) Now that you've got access to the ring, the solution is obvious -- use it to snap the upper arm back into the gear-like fitting. When you're done, the arm will rotate freely in the fitting.
(4) Put everything back together and enjoy the fact that you didn't have to pay some yobbo $75 to come to your hous and do this for you!
(HINT: When screwing the gear-like fitting back into place, use the old machinist's trick of pressing gently and screwing backwards until you feel a click. The threads will now be aligned for you to screw things together the right way. If you do not do this, you might experience frustration reattaching fitting -- since the piece it screws onto is spring loaded.)
Hello there: Here is a few things to try ok? Make sure all spray arm holes, top and bottom, are clear of foreign
matter. Does the bottom spray arm turn freely by hand or does it
bind? Check under the bottom spray arm to see if the seal (split ring)
or the bearing is worn. Check all other seals in the filter system and
impellers closely for any wear for if they are swollen. If everything
checks out OK and you have lots of water in the unit and the motor is
running you should be good to go. Hope that this is very helpfull for you Best regards Michael
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!
Br, couple of things you can look for here. Check the vent, you can just pop this out. Sometimes there is a buildup of gunk which will hold water during wash and leak down between the door. There is a seal there, part number 974782. Another thing is to check the upper spray arm for cracks or splitting. This can send a direct flow of water into the vent. There is also a seal at the bottom of the upper spray arm, part number 3376846. I was fooled by a leak like this once, it turned out to be a clogged vent...Catriver..post back.
First thing you want to do is make sure the spray arms themselves are o.k. The ports are not clogged and there are no cracks. Once you are satisfied this is not the problem, check the seal ring on between the lower spray arm and the spray arm support on the pump. See if it is out of position or damaged. Make sure the water level is not too low, should just come in contact with the bottom of the heating element. Next check your filters, look for garbage, plastics, anything that would clog it. Last would be the pump itself. Ron
