LG dishwasher does not seem to clean items on lower rack

Unit does not clean items on lower rack. i see there is a cycle that only cleans the upper rack. does the unit need to be reset or something of that sort. to my knowledge we have never used this upper rack cleaning cycle.

    I have the same problem and I can only guess that the flimsy gaskets underneath the apparatus at the bottom of the tub need replacing. I took mine apart and found those gaskets in pretty bad shape. I've only had the unit about a year and a half and I think it is too soon for gaskets to need replacing. However, nothing is clogged, the upper rack is getting clean and too many dishes on the lower rack are getting clean for me to think that it is operating in the "upper only" mode.

    If you get a solution, email me at hwparrish@sbcglobal.net

    Another posting says the reverter motor is either stuck or broken. The other posting seems to indicate sticking is the problem.

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!

Why doesn't my Bosch SHU43 c06uc dishwasher have any cleaning force?


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.

LG LDF6810ST dishwasher won't clean and spin arms properly


Check for a worn bushing washer on the lower arm. Also, make sure the arms are clean inside - they are propelled by reaction from the water jets spraying out, and clogs will prevent proper water flow through the jet orifices. Sometimes food debris will get through the pump and cause this problem. The diverter valve may also have trash inside clogging it and keeping from seating properly - this could account for both low pressure at the spray arm and water coming out of the lower rack when it should not.

Upper rack is not cleaning. Greasy dishes on top seem that dishes are not being washed. Seems the upper water turning dispenser is not working, Bottom rack seems ok. I guess I only have half a dish washer...


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.

Lg LDF6810ST dishwasher not cleaning top rack


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!
If you have problems after this, please post back what you are seeing.
Good Luck!

LG dishwasher wont clean top rack dishes


If the unit is cleaning the bottom dishes normally, try unplugging the unit for 5 minutes to reset the control board.  If that doesn't work, then the control board needs to be replaced.  The problem is that control board is not diverting the water to the upper wash arm during the cycle.  Possibly a program problem
