The spray arm on the upper basket does not spin, water does come through the holes, but only the crockery directly above the arm is being washed. the arm is not stuck or caught on anything as it turns easily when touched. there is nothing blocking the water flow.please help

Re: spray arm does not move
Before you do anything else, just check that you haven't put the upper spray arm on upside down. Having made the mistake myself, I can vouch for how easy it is to get wrong on some models.
I think this is one of those machines where the upper spray arm rides between a couple of teflon washers which act both as seals and as bearings. These wear out eventually, with two effects. One is that you lose pressure at the holes in the spray arm which are supposed to drive the arm round, and the other is increased resistance to turning. Have a look at the condition of the washers; if in doubt, replace them.
I don't think this is one of those dishwashers where the upper arm is fed through a telescoping pipe running from the upper basket to a nozzle in the cabinet roof - but in case the system has filed this problem against the wrong model number, I'll just mention that these telescoping arrangements need to be kept clean, otherwise the pipe won't close up to and seal against the nozzle, and again you'll lose pressure. If you've got one, check it moves freely.

Re: spray arm does not move
The spray arm is moved by water spraying out of angled jets at the end of the arm. the mostly cause of no rotation is these jets being blocked - its not always obvious. remove spray arm and run water into centre hole and see if you can see anything blocking the jets
- If you need clarification, ask it in the comment box above.
- Better answers use proper spelling and grammar.
- Provide details, support with references or personal experience.

Check the spray arm nozzles for being blocked. The end nozzles, spin the arms around. The upper holes wash the dishes. If your model has a top spray arm, the nozzles will be underneath to direct the water down.
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.
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 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
Sprayers require water to pass through the jets to provide motion to the arms.
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).
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?
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!
If the spray arm is not binding due to worn out plastic bushings, then it could be a lack of water pressure, because it is water pressure which makes the arm turn. Give it a gentle tap in a clockwise direction,,does it spin easily? If it does,,then it will be lack of water pressure that will be the cause. Possible pump wear or failure.
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
