Question about LG 24 in. LDS 5811 Built-in Dishwasher

1 Answer

Not cleaning on top rack. Pump, fill tube asm. & spray clean. Has any seen if this issue could be the deverter motor in the pump or the control board?

LG DISHWASHER M#LDS5811WW, S#704KWNMOO431, NOT CLEANING GOOD ON TOP RACK. WASH PUMP ASM. WAS DISMANTLED FROM SPRAY ARM DOWN AND FOUND VERY LITTLE IN PUMP.CLEANED OUT. SPRAY ARM AND FILL TUNNEL ASM. GOING TO THE FILL ARM WAS ALSO CLEAR. STILL NOT CLEANING GOOD. NOT SURE IF PROBLEM IS POSSIBLY WITH THE DIVERTER MOTOR THAT SUPPLIES SPRAY ARM WITH WATER OR THE CONTROL NOT TELLING THE DIVERTER TO TURN AND ALLOW THE WATER TO GO INTO THE UPPER SPRAY ARM. DO YOU KNOW IF THESE UNITS HAVE THIS ISSUE SO THAT I DON'T HAVE TO UNINSTALL THE UNIT TO CHECK THE DIVERTER VALVE IN THE BOTTOM SIDE OF PUMP ASM.?

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.

Aqua Glass whirlpool, Indulgence collection, pump turns on and works briefly, then jets stop.


First of all, what you have is a WOW pump that has an E-switch for a control.
There is a knob on the top lip of your tub that you turn a 1/4 turn to turn this pump on/off.
There is a small circuit board inside the box on top of the motor. This is likely the source of your problem.
Here is your biggest problem. That little circuit board is not made anymore. We have the e-switch but you will be better off changing out the pump (which you have to do anyway) with a new WOW pump with an air switch and change the switch on the top lip of the tub to an air button which will turn the pump on/off.

Not cleaning dishes


Good Morning Lynn, thank you for your post!

I understand your dishwasher is not cleaning properly. Will the spray arm rotate freely or is it damaged? If so, you might have to remove and replace the spray arm assemblies. The top spray arm typically starts to function when the unit is in rinse or wash cycle. If for some reason the top rack is not getting clean, there is a possibility that it is not working properly. The top spray arm is either blocked by pots/pans or not enough water pressure is being pump meaning that the flow of water is not making it to the upper spray arm. If you tap the delivery tube that feeds this nozzle and the water pressure jumps immediately, then the problem may lie with a faulty pump or impeller. Should all basic troubleshooting measures fail contact a certified technician to narrow down the precise issue before investing in parts that may or may not be the root cause.

Top Rack does not clean, Pump was just replaced. No Error codes. Heat is good, house water pressure is good, drain is good. I've cleaned the filter.


You do not say if the drain pump, the main motor, or the entire motor / sump assembly was replaced. If all the holes in the upper spray arms are clear, replace the VIRO motor. It is a small motor next to the main motor, and it switches a water valve to divert water to either the bottom spray arm or the top spray arm, intermittently. (normally about a 2 minute cycle, unless a "top rack only" setting is selected, etc.) The dishwasher has to be removed from the cabinets to replace it.

Top rack dishes not getting clean


Hey- Two things could be wrong.- clog, or bad motor. Sump screen needs to be cleaned of debris. Removal of sump cover to access screen requires torx bits and some patience. Replacement of pump requires pulling out dishwasher to access bottom. Motors fail when seal between motor and pump fails. Will still operate, but become weaker over time. Parts available- motor about 100$ at appliance parts pros.appliancepartspros. Hopes this helps- Thanks- ED

Dishwasher not cleaning dishes on top rack


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.

There is a screen that you can remove from the sump of the dishwasher to clean. Just twist it to the left and pull it out. I have some tips that you might want to check out if this does not resolve your problem.

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!

Dishes not washing clean


check water level in machine
may be not filling enough and the wash pump is starved from water thus not pushing water to upper arm
drain water from machine dismantle and clean out air tube to pressure switch take off air tube at pressure switch and blow back into sump then pinch air tube with fingers to stop air from flowing back up tube then refit to p/s
run and see if that solves problem
