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?
It should pop on and off
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

the spray arm just screws back on, unless of course its cracked in which case needs replacing( chances are since it fell off its cracked) heres the part num 154478202

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!

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.
hold spray arm at base and turn counter clockwise..good luck
New Spray arm split around center joint so when it gets hot it opens up spraying water under door
take it back for another

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!
