Question about LG Dishwashers
Is disposal newly installed? If so, there’s a knock out plug in inlet to disposal. If that’s not it, disposal or drain is obstructed

the obstruction they talk about in the disposer, its where the connection for the d/w drain is made, there is a "knockout" plug within the drain line connector( in case you dont have a d/w) that would need to be removed before the d/w will drain. can be popped out with a good smack with a screw driver, the plastic knockout will land within the disposer. disconnect power and remove the plug, it will not break up and wash away

SOURCE: OE Error
You do not have an "OE" error, it is actually a "DE" error. (Drain error) If after 5 minutes of drain time the pump motor RPM's haven't gone up the dishwasher knows that there is still water in the tub and throws the "DE" error. Often times the problem is the controller, but I have found more often that the problem is a long and/or restricted drain line. If someone had to extend the drain hose to reach a drain the extra resistance from the splice and pushing all the extra water in the long drain line prevents the dishwasher from pumping out within the time limit.
In some cases it is possible to correct this condition by first making sure the drain hose has a high loop to prevent siphoning, then running the drain line through the floor and into an open trap. (again, to prevent siphoning) Do not use extensions on the dishwasher drain hose supplied with the unit.

Well, there is the plastic block in the garbage disposal where the drain hose goes on (as not every disposal will be attached to a dishwasher). Punch this out with a screwdriver, fish the plastic plug out with your hand and reattach the hose. You are good to go.

The most common cause of an OE error code on a modern LG dishwasher is:
1. Blocked drain hose
2. Obstruction in the sump area (beneath the filter, which needs to be removed to check for onstruction)
3. Failing drain motor.
else you need to REPLACE THE PCB POWER CONTROL BOARD

If there is any blockage in your diposal, water will comes up to the sink, since it happened to me. As soon I installed the air gap then it fixed the problem. No air gap, water flowing is slowing down conflicting with timed draining causing this problem. Let's think of this, if you fill up water in a 1/2 galon milk container, and you try to emty it. If you pull down straightly , it will be slow compared to pull it at an agle to let air going into the opening. The air vent helps water flow better meeting the timed draining.

Tips for a great answer:
Your dishwasher drains into the garbage disposal. It you tried to use a plunger to clear your clogged sink or run the disposal with to much junk in it you may have force debris into the dishwasher drain hose. With both the dishwasher and garbage disposal disconnect from power disconnect the dishwasher drain hose from the garbage disposal. This is usually about a one inch black hose. Clear out any debris in the hose and inlet nipple on the garbage disposal. If debris is compacted far down the hose it will need to be disconnected from the dishwasher end and remove to clear the blockage.
