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. A. A.

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

The upper spray arm came detached, how do I reattach it?


On my dishwasher, this arm attaches with a huge gray plastic screw. If it comes loose, you'll usually find the spray arm sitting in the bottom rack, but the screw falls down to the bottom of the tub.

The spray arm has a hole that goes all the way through its center. One of these holes is larger than the other, so the arm will only attach in one direction. Most of the spray holes on the arm face "up" when installed.

Slide out the upper rack, position the spray arm on its pivot, then insert the screw and turn clockwise to tighten it. The arm should spin freely.

If this arm isn't attached, none of the dishes will wash well (due to a loss of water pressure).

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.

My dinner plate stops the arm rotating, why? model fdud4812


Both upper and lower washing arms operate on the water pressure and angle of water flowing thru them.
Pressure provided by water pump.

Just about anything that contacts the rotating arm can stop it.
Best thing to do is re-arrange items in dishwasher so that arms can spin freely.
One can always spin washing arms by hand to ensure proper clearance.

Hope this helps...

The top shelf is not getting clean. There is food residue on the glassware that was not there at the start of the wash.


Hi,

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

Regards,
BElectric.

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).

Maytag MBDF550Aww upper spray arm doesn't spin.


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!

The top tray of our Indesit DI620 isn't washing properly. I suspect that the spray arm isn't squirting water, it isn't impeded by badly stacked crockery. I can't work out how to detach it so that I can...


If you want to see if water is getting to the upper spray arm you can open the door while it's washing for a quick look before it stops or if you can manually press in the door latch with the door open you'll get a good look. You'll also get water in your face. It's probably a pump problem. The vanes in the pump can get damaged which means the pump can't push the water to the upper arm.

Top arm not spinning


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. otherwise....

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 spray arm.
