OE Code keeps coming on screen LG Dishwasher LDS5811WW
Have checked all the water lines and taken off the lower spray arm and taken out pump. Water drained, ran DW again and the same problem. When I turn it on, it sits there, grinning at me as if to say I am up the creek. I thought LG products were a good product...I am starting to wonder.

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.
There is a possibility the water pressure itself is low from the kitchen line or the dishwasher is set at incorrect water pressure setting and does not collect enough water based on the flow time of inlet valve. If you hear the wash motor cut in then there is not enough water in the base to start pumping it to through the arms.
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.
Possible that the drain pump/valve is faulty or is clogged. It is best to check the voltage on the pump/valve of the washer , if absent the program controller must be checked., if present with no drain then the pump/valve is clogged /failed and must be taken out to be cleaned or replaced.
if the soap/detergent isn't completely rinsing out of dispenser, it sounds like water isn't directed the top spray-arm. possible a defective vario motor; as it directs water to the water channel that supplies water to the middle and upper spray arms.
When you say the top arm does not spin, remember that the LG model x811 family has the Vario feature that alternates between routing the pumped water to the bottom arm and then the top arms alternately. So anytime the dishwasher is washing and rinsing, either the lower or upper arms will be spinning.
If the problem is not above, then the motor that drives the check valve may have failed (or the check valve is obstructed inside.)
Hope that helps. Please post back here with what you find, OK?
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?
What did you find the problem to be?
On an LG dishwasher, I am not aware of an E0 error. But there is a "OE" error code (as in output error)
The first thing to check is the lower sump area - remove the filter beneath the spray arm and look everywhere for blockages that have slipped through. If that is not the problem, the drain motor has probably failed.
