The upper spray arm on my dishwasher has stopped spinning during the water cycles. Everything is getting clean on the bottom but the top, not. The normal 'swish' you can hear when it is running has been replaced by the sound of running water. Of course, everything stops when I open it up so I can't see what is happening but it is obvious it isn't spinning at all.
Lots of water seems to be getting through from the sound of it, however it is not pushing the arm. The hanger at the back that guides the manifold into the feed tube assembly is cracked at the bottom, so I've ordered a new one, but I don't think that's likely relevant.

Re: Water Problem in Upper Wash
Dishwasher arms are only swept round by the water spraying out of the jets some of which are at an angle. make sure jets are clean and if necessary take the spray arm boff to get debris out. usual culprits are sweet corn and rice

could be a few things clean inside filters and screens listen to it does the wash motor during wash sound strong like it tossing water around in there open the door during the wash see if kicks some water out at you. If it sounds and seems like its working ok then some units have a rubber check valve little flapper in the tube that goes up the back wall to the upper spray arm i have seem break off and clog that tub not allowing any water to the upper spray arm.
It could be a motor or a pump issue. The dishwasher has a motor that attached to a pump which forces the water up into the sprayer arms and during the drain cycle, it pushes the water out of the dishwasher. The motor (and pump) located beneath the dishwasher. Check if motor spins. In case it spins, the problem is with the pump ,in case it doesn't spin it could be a motor problem or a motor and pump problem.
First of all: filter plate clean? Clean any locked hole. 1) Can you remove the upper spray-arm and verify if holes inside are locked by any residus. Clean the holes , and check if pure water come out when you fill the center hole with some water. 2) Switch on the dishwasher , coldest wash cycle dish-washer empty and without the upper spraying arm. Once you hear water streaming in, open the door and look if a little water fountain comes out from the center hole where the upper spraying arm was fixed. If not, this canalisation is blocked and should be cleaned. Try to continue the wash cycle, often the water pressure will clean itself this canal. Check also lower spray arm: it should be rotating a while and ejecting water thru its holes. If not, verify this canalisation as well.
3) Put the spraying arm again on its place, verify also the sealing else water pressure is going down and spraying will not turn and spray water.
4) Again, continu a wash cycle, open the door and look; upper arm should be rotating and some rays trown out.
Hopefully, this helps .
If not, pump pressure may be low; have a repair verify, can be that only brushes in the motor must be replaced, can be the pump worn out and to be replaced at all.
It will spin freely by hand, but needs to spray water out of the jets at the trailing edge of the arm. Check inside the arm for blockage and make sure that water is getting to the upper arm from the pump.
The most likely answer is that your upper rotor spray arm isn't spinning or spraying water. They aren't powered by a motor - they are driven by water pressure. The most common reason for them not spinning is a blockage somewhere. The lower rotor arm is spraying dirt from the plates in the lower rack onto the glassware and there is no spray from the upper rotor arm to rinse it off.
Check the small spray holes on the top of the upper rotor arm. If they are blocked, use a large pin or a cocktail stick to clean them out. If they aren't blocked, check to see whether the upper rotor arm is spinning by following these steps:
1. Note the exact position of the upper spray arm or spin it so that it is running precisely left to right or front to back 2. Close the door 3. Start any wash cycle 4 After it has finished filling with water and starting cycling the water, open the door and note the position of the upper spray arm again.
If the spray arm is in the exact same position as when you closed the door it's almost definite that it's not spinning. In this event, cancel the wash and do the above test one more time just to eliminate the element of pure chance.
Try the above tests and checks and then post back with the results if you need any further assistance. If posting back, please include the full model number of your Frigidaire dishwasher
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)
ok so If your dishwasher has worked fine in the past but, suddenly, your
dishes aren't clean after the dishwasher completes all cycles: 1) Check your water heater's temperature dial to
be sure it hasn't been changed recently. 2) Be sure dishes haven't prevented the detergent
dispenser from opening properly during the wash cycles or kept the spray arms
from turning, the lower arm from rising, or the spray from reaching the upper
rack's dishes. 3) During the wash cycle, listen to the spray arm
spinning inside. If it seems to be spinning poorly, clean out the spray holes
in the spray arm(s) with a stiff piece of wire; wait for the machine to cool,
and then remove the spray arm(s) by unscrewing the hub cap and lifting the
arm(s) off RegardsGizokieth
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
On the LG LDF xxxx dishwasher family, the Vario feature uses a motor/check valve to switch between "full power" cleaning from _either_ the lower or the upper spray arms, never at the same time. So, not seeing the upper arm spin during the lower arm spinning is standard operating procedure.
But back to your problem. Step one would be to remove the filter assembly again and make certain that there is nothing (debris, broken glass) blocking the white areas where the check valve rotates to switch between upper/lower spray arms. A blockage there ~could~ cause impotent spraying/cleaning.
If there is no blockage and the impeller remains in good shape, suspect a failing wash pump motor. Try to isolate the noise to that motor.
Watch for error codes on the display and report back what you find, OK?
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.
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
