Cannot remove "base spray arm"

I have a hotpoint hda3500n00bb and it has a broken "base spray arm". I have the new part and it looks like it should just screw into the hole that leads down to the pump. But i cannot get the old "base spray arm" to screw out. I mean it is not budging! Any suggestions?

    I'm 99.9% sure it doesnt' just pop off. It has threads. Here is a picture of the part.

    Thanks, I think your observation of the grooves creating a lock is correct. Unfortuneately, I think someone put the piece in my dishwasher incorrectly so it wasn't popping up like it should. So, I just cranked on it in with a makeshift lever in the clockwise direction until the grooves lined up better. Then I was able to pop it up and unscrew it.

    I was afraid to crank on it because I didn't know what was holding it in there and I didn't want to ruin the pump motor. Your comments were what led to the fix. Thanks again!

    ok you see where it has that pice in the center you need to push that pice in to remove the spinner then pop up the little round catch and unscrew if you look at it from bottom you can see the round part I'm talking of what happens is when you screw it in it is used as a lock you need to pry it up to unscrew

SOURCE: Hi I have a Kenmore model

The top rack is not cleaning because of low water pressure from the wash motor to the upper spray arm.
Assuming the top spray arms are clear of debris, remove the lower spray arm to access the wash motor. Remove the 4 torx screws and the filter (accumulator assembly). Remove the torx screw and the inlet protector that covers the chopper assembly. Make sure the chopper is not broken (broken chopper will fill with debris and block water flow). While holding the chopper blade, reach inside the "D" shaped opening on top of the motor and spin the wheel/motor by hand in each direction to make sure either the chopper gear or the motor gear that drives the chopper is not broken. Replace the chopper if necessary (part # 8268383). If the motor gear is broken, replace the sump and motor assembly (part # 8535150). Remove any debris from the sump area in the process.
You don't have to because the door will be open, but if you feel more comfortable shutting off the power to the dishwasher, do so.
Good luck!

SOURCE: 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!

SOURCE: 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!

I have had a similar problem numerous times, a couple of which required manoeuvreing it into a place I could work on it, and a laborious removal of the covers. Each time, up until this current incident, the solution that worked, at least temporarily, was quite simple. The recurrent problem was at least consistent: every 6-8 months I would find that the pump would work but the spray arm was not moving. The solutions always seemed to be something different: once all I needed to do was to prime the pump, other times it seemed like calcium and lime build-up was clogging up the parts so a little C.L.R. got me on my way.

This most current incident was more baffling, as my standard solutions did not work. However, I think I finally got to the root of the problem.

Look inside the dish compartment, to the right, near the top. There are two little nubby holes. Their function is to allow air to enter/exit either the spray arm pump tubing or the water filling tubing. Remove the one zillion screws from the cover to access the innards. Pull off the tubing and unscrew the washer (it will be tight due to the sealant on it). Upon inspection, I found that the air hole for the spray arm pump was clogged with food residue. A tiny screwdriver will clear things out nicely - you should be able to see through it. If you clear it out a little but, but still can't see through it, then I presume you're just going to have the same problem back again.

It is important that this be clear so that the water can displace the air while filling is occurring and allow for good suction. Actually, it looked like a manufacturing flaw - there was still some residual plastic from the original molding on the inside, and food was getting caught on it.

Good luck.

SOURCE: upper spray arm failure

Easy to solve!
(1) Remove the drawers to give yourself room to work
(a) bottom drawer just comes right out -- but you knew that
(b) Carefully unclip small plastic retainer caps at the ends of the metal "glides" for the top drawer. Then slide the caps out of the glides. Then remove the top drawer.
(2) Unscrew the "gear-like" plastic fitting into whose hole you were sticking your finger when you felt that small cylindrical ring.
(3) Now that you've got access to the ring, the solution is obvious -- use it to snap the upper arm back into the gear-like fitting. When you're done, the arm will rotate freely in the fitting.
(4) Put everything back together and enjoy the fact that you didn't have to pay some yobbo $75 to come to your hous and do this for you!

(HINT: When screwing the gear-like fitting back into place, use the old machinist's trick of pressing gently and screwing backwards until you feel a click. The threads will now be aligned for you to screw things together the right way. If you do not do this, you might experience frustration reattaching fitting -- since the piece it screws onto is spring loaded.)

Upper spray arm not working


I had the same problem with mine, where the water comes in at the back inside of the machine there is a big plastic nut. When i took this off, there was a broken seal. I have replaced this seal and it worked again for about a week. Now the bottom and top arms arent working. Looking at these forums it may be the circulation pump that has something blocking it but am now trying to find information on where this is and how to check it!

My hotpoint aquarius is leaving dirty residue after the full cycle - do I need a new dishwasher?


The problem is most likely that there is still water residue at the bottom of your machine. If the machine is not fully drained it picks up some of the residue and sprays that onto the dishes during the final rinse, leaving an unhealthy and unsightly film on everything.

Remove the bottom strainers plates and make sure that the outlet pipe is not kinked, that there is nothing obstructing the pipe or the pump or selector valve. If possible back flush through the outlet pipe and try draining the machine once more before using it again.

Frigidaire dishwasher - upper spray arm trouble?


I do not have a problem w/the upper arm not spinning. Rather, the upper arm keeps falling off of my frigidair dishwasher. The owner's manual suggests the upper arm is a single unit. However, the upper arm component is comprised of 3 parts. The parts are an arm that distributes the water, the base that screws to the top of the dishwasher, and a small plastic type washer that rides in the base and literally holds the arm to the base. The plastic washer has two small clips that tend to wear or contrast with age; thus letting the arm fall off on a very frequent basis.

Potentially, the small plastic washer piece may have broken in the base assembly and is not allowing the arm to turn. As water flows into the arm from a hole in the base; suggesting the plastic washer may be jammed with a foreign item seems less likely. The base unit screws to the top of the dishwasher and can be removed by hand (the base is a little tight). There are no mechanical pieces to my third (upper) arm; movement of the arm is accomplished with water flow.

You may wish to remove the arm assembly and check for a broken washer or a foreign item in the assembly. As a side note, I found that I can unscrew the base and remove the assembly without removing the top dish tray. The fit is a little tight but the tedium of pulling and reinstalling the top tray can be eliminated by unscrewing the assembly w/the tray slid forward for assembly access.

Hope all you have is a foreign item that is locking the washer.

Leaking FDW60


Had a similar problem when I removed the lower spray arm for replacement (see http://www.fixya.com/support/t234402-fdw60_dishwasher ) and didn't put the centre retaining nut back. It might be worth checking the lower arm is screwed in tightly as the retaining nut prevents water escaping.
