If your LG dishwasher displays error code OE, it signifies that a problem with the drain has been discovered.

While you may be able to solve some simple drain faults yourself, more complex issues may require the services of a professional. Here are several options for dealing with this issue.

Food Debris

If you encounter error code OE on your LG dishwasher, the first thing you should do is check the drain hose to make sure it isn’t clogged with food particles.

Remove the hose from the sink drain and flush it out with water to complete this. If there is no blockage in the hose, your dishwasher may require a part replacement.

After that, detach the motor assembly from its mounting bracket by pulling it out and disconnecting any wires or hoses attached to it.

However, it might not be enough for a clogged spigot in some cases. You may require to clean the spigot with water.

To resolve this issue, disassemble your dishwasher and search for the spigot. This can be found in the back of your machine and is connected to the pump unit by a hose.

Once you’ve located your spigot, use warm water and a toothbrush or other tiny brush to clean it out. It could be clogged with a lot of food particles or hard water deposits.

Pressure Switch has Defected

The LG Dishwasher Error code OE can also signify that the pressure switch has defected.

To resolve the issue, disconnect the dishwasher from the power source. Now, you have to wait for at least 10 seconds before plugging it back in.

If the problem persists, the switch may need to be replaced.

Moreover, here are some of the steps which you can try to fix the defected pressure switch issue:

  1. If you wish to try to repair the pressure switch on your own, the first step is to disconnect your dishwasher from the power source.
  2. Then, remove the access panel by unscrewing the screws that hold it in place.
  3. A drain hose should be located just within the panel itself. Make sure it is not clogged with trash.
  4. If the pressure switch isn’t clogged, you’ll need to replace it.
  5. Remove the pressure switch from your dishwasher by unplugging the electrical connections on either side of it.
  6. Then, before reinstalling the access panel and hooking everything back in, install a new pressure switch and reconnect all of your hoses and electrical connections.

How to force the drain?

Forcing the drain is one of the simplest ways to fix the OE error code on your LG dishwasher.

Then, clear out any material that may be clogging the drain and inspect it for cleanliness.

Many modern LG dishwashers also have an option to force drain. You can use the Cancel and Drain option to force drain the water.

To activate this feature in your LG dishwasher, you need to press some combination of buttons.

For instance, it is mostly DELICATE + DUAL Control and Spray + Half Load, all of them together.

However, if this option does not exist in your dishwasher, then you need to start a dishwashing cycle and let it run for about 1 minute.

After that, turn the dishwasher off and then run it again for about 1 minute. In the first cycle, the water may get drained. But if it doesn’t, then you need a professional.
