We've got a frigidaire dishwasher (model number fdb2810ldc1) that's about 3 years old. It has a white plastic spinning arm thing on the inside top of it that keeps falling off and driving me mad! I think originally a tall glass or dish must have hit it to knock it off, but now any little movement makes it fall. We keep putting it back on, but the top rack has so much play in it that we have to carefully lift the rack instead of just pull it out or the stupid arm thingie falls off again. I'm ready to throw the whole thing out the window, but my husband says it's too new to justify buying a new dishwasher. Can someone tell me how to fix this thing? Thanks!

It would help if you provide the model number. Usually the problem is with the wash distributor circuit. The water alternates between bottom and top spinners (wash arms). The distributor may be faulty assuming the arms are clean and you have checked this. Some models use the same pump for wash and drain using impeller. In that case the problem could be the impeller is clogged and not allowing water to get in the arms. See this diagram.
The top arm snaps into place. Simply unscrew the retaining clip from the ceiling of the washer. Inside of there, you will find a small white plastic clip. Make sure the two prongs are pointed down and poking out through the hole in the bottom of the larger grey clip that you just unscrewed. Then press the prongs on the white clip into the hole on the arm and snap it back together. Then you can screw the assembly back into the ceiling of the washer.
If this problem persists, you will likely need to replace the white plastic clip. (which is where I am at right now with my washer).
This just happened to me. The spinner arm fell off. It left behind two pieces of plastic attached to the roof of the machine: a grey sunburst shape, and within that, a white circle with two prongs. It looks like the spinner arm should snap onto the white circle with prongs . . . but you can't just press it back on, because there is no resistance on the other side and the white circle just becomes displaced instead of snapping together.
But the good news is that the grey sunburst screws on and off! Unscrew it until it comes free from the roof of your machine. Now snap the white circle and the spinner arm together, with the grey sunburst between them. Give it a test spin to make sure it's all together and working, and then screw the whole assembly back onto the roof of your dishwasher.
Apologies for the lack of pictures . . . this must sound crazy to anyone who's not looking at what I'm looking at--but it worked!
The top spinner part can simply be pulled off by grasping it near its hub and pulling downward. Push it back on and push in the locking clip in the center.
The bottom spinner can be removed, First unscrew the center column. Hold the spinner with one hand, turn the base of the center column counter clockwise. Then lift column off. Then the spinner should lift off of the keyed white plastic base. Underneath it, on the neck off of which you lifted it, are two plastic washers that form a seal (supposedly). Good to clean these to make spinner rotate freely, but be careful not to break them taking them off.
If you want to go farther in, there is the point of a strange shaped plastic nut sticking up into the base of the column. If you remove this, and the 6 torx screws holding the strainer cap, you can get it all out to clean it up (I had bits of plastic bag in the slots of a 4-armed thing that apparently sprays the filter screen), and scrub the washer in the bottom. Remarkably yucky down there in a 10 year old installation...
First, confirm that the holes are not blocked on these arms. (I did not want to assume you have done this.)
Then check the impeller on top of the motor stem for being loose or worn/damaged - to rule the impeller out. If it is fine, then the motor is failing and too weak to drive the spray arms. To answer your question, I think the answer is "They don't make them like they used too!"
I had the same problem, the 3rd level spinner falling off. Without getting into my saga story, save yourself some $$$.
-You will need a screw & washer to replace the plastic thumbtack. The screw will have to be able to screw into the female part of the spinner; the washer will keep the screw from falling out of the hole in the flat hose on the ceiling of the dishwasher.
-If you look closely at the spinner(the part that keeps falling off), you will notice it comes apart. With a flat head screwdriver, separate the 2 parts. (there are 3 parts all together; Keep the round center piece sticking out of the top peice)
--Remove the top drawer of the dishwasher to give you some room to work
-Remove the screw on the "ceiling" of the dishwasher(it is located further back from where the spinner goes) to allow the flat pastic tube to come down low enough for you to get in behind it.(set that screw aside in a safe place; you will put it back later)
-Remove the pastic thumbtack from the hole in the flat plastic tube if it is there & replace with a washer and screw.
-Take the top 2 peices of the spinner, together as assembled & screw the screw into the female portion of the spinner.
-snap on the 3rd piece of the spinner
-replace the screw you took out earlier, securing the flat plastic tube.
-place top drawer
Voila, you are done!! You just saved yourself $20+
