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).

Most dishwashers dispense the detergent via gravity and the sprayer arms spraying against the soap dispenser once the little door flips open during the wash cycle. Since it sounds like the soap door is opening I would look at the sprayer arms and make sure they are free of food particles or other debris that might be keeping them from rotating and spraying properly. Here are some instructions for performing this check.

Remove the lower dishrack from the unit. Reach into your dishwasher and spin the lower spray arm. Take note of whether or not the arm moves freely or if its movement is restricted. It should not be restricted in its path of motion. Now gently pull up on an end of the spray arm. The spray arm should be free to wobble up and down. Unscrew the arm retaining knob (some of these are left hand threads) and take the arm out for inspection and carefully examine the spray arm seams. If they have split or are damaged, the dishes may not receive the amount of water pressure required to fully clean the dishes or to rotate the arm properly. What’s more, if water is in fact spraying out of the spray arm from its seams, it is possible that it can cause your dishwasher to leak. Make sure there is no debris in any of the holes.

If your dishwasher has a spray tower, pull up on it as far as it will go and then let it fall back down. Again, this movement should not be restricted. It should be a fluid and smooth motion. Also, unscrew the spray tower and examine it for any debris or foreign objects. Remove any that you find.
Gain access to the upper spray arm by removing the upper dishrack. Perform the same tests for the upper spray arm as you just did for the lower spray arm. Keep in mind that the upper spray arm may not wobble as much as the lower spray arm.
On a final note, some dishwasher models have a water tube that meets up with the upper spray arm once the upper dishrack is pushed back. It is a good idea to check to make sure this tube is aligning properly with the upper spray arm and that this has not split or is damaged in any other way.

Tablet keeps coming out of the dispenser on my hotpoint fdl 570 dishwasher on all cycles and falls on to the floor, result is that the crockery isn't always clean on the top tray. Machine is still...


Hi Jeanette,

Maybe I misunderstood your question, but the tablet is supposed to come out of the dispenser and fall into the bottom of the dishwasher. It needs to fall into the hot water in the bottom of the washer to dissolve. The dispenser releases the tablet at different points in the cycle depending on which wash cycle is selected. On a shorter cycle it will be released soon after starting. On longer cycles, there is usually a rinse first, so the tablet will be released a little later. There would only be a problem if the tablet wasn't being released, or wasn't dissolving completely.

There are a number of reasons for poor cleaning on the top rack. The most common are the upper spray-arm not spinning, incorrect stacking or overloading. If the upper spray-arm isn't spinning, there may be caused by a blockage in the spray-arm or the water delivery system, but, as the dishwasher is new and it's not happening every time, it's possible that the dishwasher isn't levelled correctly. The spray-arms aren't motorised, they use water pressure to spin, but they wont spin if they aren't balanced, i.e. the dishwasher isn't level.

You can check whether the spray arm/s are spinning by pointing them front-to-back, or left-to-right (so you can remember the position) and allow the dishwasher to run for a few minutes. Then open the door and check the position of the spray arms. They should continue to rotate slowly for a short while after opening the door, but if they're in the same place and static, they're not spinning. I'd suggest repeating this a couple of times to eliminate the possibility of them having stopped in the exact same place you left them.

If the spray arms are spinning, test the dishwasher with only a small load in the top rack. If the top rack comes out clean with a small load, you may be overloading it or stacking it incorrectly some of the time. There should be a correct stacking guide in your user manual.

Hope this helps. If you need further assistance, check whether the arms are spinning then post back.

BElectric

Dishwasher Residue and Film on Dishes

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

Top arm in dishwasher will NOT spin!


When you say the top arm does not spin, remember that the LG model x811 family has the Vario feature that alternates between routing the pumped water to the bottom arm and then the top arms alternately. So anytime the dishwasher is washing and rinsing, either the lower or upper arms will be spinning.

If the problem is not above, then the motor that drives the check valve may have failed (or the check valve is obstructed inside.)

Hope that helps. Please post back here with what you find, OK?

There is a kind of grinding noise.


The most common reason for a grinding noise on an LG dishwasher is debris getting stuck (rather than ground up in the build in disposal.)

To resolve, remove the approximately 9 screws on the filter assembly in the sump area. You will need to remove the lower spray arm to get the filter out. Grab the spray arm and lift up and out.

Use a flashlight to inspect the entire area, especially in the rear area that has the valve that alternated sending water from the lower spray arm to the upper spray arms. I bet you fill find something lodged in there. Please be careful of broken glass as it can be almost invisible in water that remains in the sump area.

Please post back here what you find, OK?

LG LDS5811WW Low pressure out of spray arms


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?

Good Luck!

Dishwasher problem


The LG dishwasher family has a cool feature that alternates the full wash/spray power between the upper spray arms and the lower arm.
It is called Vario - with a motor that drives a check valve to route the water.
So, If you just open the dishwasher while it is running and look to see if all the spay arms are spinning, you will be disappointed.
Now, if you are having problems with dishes not getting cleaned, we need to take the next step. Post back what you find.
Good Luck!
