Im receiving an OE error code on my LG Dishwasher Model LDF7811st. The machine runs for a little bit and then it dings a few times with the "OE" code and stops running. HELP please

The machine has determined it is unable to drain water. See link.

OE indicates a drain error. Your model number doesn't fit the usual pattern for LG dishwashers; LDT5665WW and LDS4821WW are a couple of recent model numbers.

To start diagnosing and fixing the OE error, first check the discharge hose. Make sure that it isn't clogged, kinked or improperly positioned. Make sure that the pipe or food disposer that the drain hose connects to isn't clogged. (Check into the rest of the drain pipe if needed.)

Next check that the float switch inside the dishwasher isn't blocked. This indicates the water level and if a foreign object is holding it open, the dishwasher will continue to try to drain the water.

Finally check for any blockage in the drain pump. Also check the pump for obvious damage. If the pump is damaged, replace it.

After you've checked and fixed (as needed) the above issues, try the dishwasher again. If the OE code recurs, then you need to replace the drain motor pump assembly.

If your dishwasher is under warranty, contact LG. Otherwise, please check and post your machine's model number. I can check to see if the parts are available.

I hope this helps.

Depending on the serial # of the dishwasher it may need a new wire harness and inner door liner.

LE is a motor circuit error.

Contact LG @ 1 800 243-0000 they may help you out.

The LG error code OE simply means "the pump is blocked". Presumably the water isn't being emptied properly. As with all error codes it is possible that there is a cause other than the exact description in the error code explanation but basically this error means as far as the washing machine is concerned it thinks the water isn't pumping out. A pump, or filter blockage is the most common cause but it could be caused by other faults such as a faulty pump, or even a blockage in the drain hose or somewhere else in the system etc.


LG themselves have some information on this error code..

Hi there,
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

Good Luck!!!

Well done by resolving this problem. The other way to avoid the siphoning problem through the drain hose is adding an air gap valve/connector (available at any hardware store). You can use it even if you don't have a garbage disposal in your kitchen sink. That will assure that you have the proper height of the drain hose.
Hope this helps!

LE stands for "Locked Motor". It means the main pump motor is bad.

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.
