decrete, you want to get down to the chopper and screen. If the screen is plugged up with gunk there won't be enough pressure to reach the top spray arms. Check out the posted pics. Remove the lower spray arm. Rotate the rear feed arm to the right until it unsnaps from the tube going up the back. See the 4 torq screws holding the filter on. Remove them. Lift the filter up. Now you will see the chopper inlet cover. 1 torq screw holding it in. Lift it up and there's the chopper and screen. Catriver..post back
SOURCE: LG LDF6920ST Bottom spray arm dose not work
The LG LDF6920 dishwasher has an innovative "Vario" motor/check valve. It switches between full power spray on the upper arms and the lower arm. So, if you are looking inside the dishwasher to see which arm is spinning, you just have not opened it when the lower arm is turning.
if the root problem is that your dishes are not getting clean with this water conserving DW, go out and buy a name brand detergent powder - like Electrosol or Cascade. And use less powder then you have been using.
Good Luck!
Just to review, the LG dishwasher family, including the LDS5811 has the Verio motor and the check valve that diverts water from the bottom rack to the top rack.
If the valve is blocked/jammed, this would cause the symptom you describe. The valve is visible from inside the DW after you open it up.
It is also possible that this motor has failed.
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!

Check the riser tube coming from the pump assembly and be sure it isn't blocked or that something else isn't obstructing the pump intake area. Make sure the upper wah arm assembly isn't excessively loose on the spindle and losing pressure because it's leaking. You may have to remove the lower rack, lower wash arm and cover to see.
If everything is clear, it could be a worn or damaged pump impeller. If the machine drains normally, it's not the motor.
Hi
Please check if something is blocked near the top spray arm, also make sure that all holes are oopen. Use a sharp metal pin to clean the holes on the top spray arm. Make sure the water pressure is not low.
under the screen and youl'll need a Torx driver to get to it after you remove the spray arm and screen. Check to see that the path it travels is clear. I have seen these get blocked up by stuff.
Now check if the top arm spins freely and check the bearings for the arm, if they are producing extra friction while the spray arm spins. Hope this helps... Please post back if you need more assistance.
