Re: LG dishwasher does not seem to clean items on lower...
Can you tell me if the problem was fixed by the original posters?
The multi-level wash direction feature uses a check valve just below the mesh filter asembaly and is driven by a vario motor underneath the check valve. By removing the mesh filter (10 screws and the lower spray arm) you expose the check valve. It is very close to the pump that empties the water through the drain hose.
High probability problems:
-The Check Valve could be jamed/stuck.
-Also, the Vario Motor could have failed
Please respond back with the findings on this problem. Thanks!

With your dishwasher empty, roll out the bottom rack. The feed line for the upper spray arm runs from a pump outlet directly behind the lower spray arm spindle. This tube runs up the back wall of the dishwasher and mates with the upper rack when it is pushed in.
This feed tube simply snaps into place in the bottom of the machine. It is a high pressure line that makes an immediade 90-degree bend towards the rear of the unit. They have a tendency to pop out. When and if it does pop out you get almost no water coming out of the upper arm and you lose effective pressure in the lower arm, too. The cure is to push that feed tube back down firmly into the port until you hear it snap into place. While you have the lowere rack out it is a good idea to clean the intake screen out and check for any debris in the intake well.
try c.l.r. to clean dishwasher check and clean lower and upper spray arms out, run no detergent you can also run vinegar in it as well about a cup full,let the machine start to run then stop dish washer for a few hours then restart see if this works for you use a short cycle.
Check the upper arm for free spinning, then remove the arm and check that the seam between the upper and lower halves has not split somewhere. Also check all the small holes for debris plugging. Run the machine in wash cycle for a little while with the upper arm off--that should flush out anything blocking the pipe up to the arm. If still nothing from the upper arm, tear down the lower arm assembly down to the deck while noting position of all parts removed. Clean the big screen at the bottom in white vinegar and hot water. Inspect the holes in the bottom for anything blocking them.
likely not .....the problem may be how you stack the dishes ....try doing a load with nothing on the bottom rack ....if the top rack items come clean then you may be stoping the water from reaching the top rack with the dishes on the bottom rack ....it's important to keep the center of the bottom rack free this is where the water comes from (on most models). to clean your upper rack .....have a close look at the inside of the machine to try and figure out where the water comes from ...it helps a lot to understand this ....good luck
I am here for the exact same reason. Mine is less than 3 months old. This may be a recall item. I bought, and paid more for a kitchen aide for the name and reputation.....Where can I find the model number?
Almost all of the problems mentioned above will be solved by having the owner buy a name brand detergent powder (like Electrosol or Cascade) and using a little less than you think you should.
For those who continue to have problems with poor cleaning, you need to remove the lower spray arm (pull straight up firmly, then out) and then remove the 9 screws that hold the filter in. Using a flashlight, inspect everywhere in the sump area (be careful of broken glass!) Remove all debris and especially look for something blocking the white check valve that is driven by the Vario motor to control the alternation between the upper sprayer arms and the lower arm. Reasemble and test.
If inside dishwasher is a mess with white mineral deposits, recommend you place a bowl filled with white vinegar on the rack of your empty DW. Start a quick cycle with no detergent added.
Check out how clean it is when you are done!
