LG Dishwasher model # LDS4821 Constanly giving a OE error on the control panel

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.

Hi

OE in your dishwasher is a drain error and dishwasher not draining issue usually occurs due to kinked drain pipe, clogged drain filter or drain pump. First make sure that the drain is not clogged and remove clogs if present. If no visible lint is present then remove the lower front access panel to check the drain filter and drain pump for any clogs, you'll need to clean the drain filter and drain pump completely. Also, check for any food pieces stuck near the pump impeller & clean the chopper assembly. If the issue returns after cleaning then the drain pump assembly should be replaced. Hope this helps...please post back for further assistance.

Hi tpearsgolf,

The "OE" error code you are seeing, means "Outlet Error"

The drain pump is either clogged, or the outlet hose has been kinked.
- Inspect the Drainage hose at the back for kinks. - If any, straighten the hose
- Open the unit, and at the bottom sump check the small drain pump area for any foreign object that may be obstructing it. You can remove the filter, as well as the metalish sieve underneath it, check the sump underneath near the drainage holes, make sure nothing is obstructing the flow out of the machine from there.

If not successful, you will need to replace the Drain Pump.

Kind Regards :-)

Hello & Welcome to FixYa

OE is a drain error and is displayed when the washer is unable to drain water. Please check the drain hose and drain pump filter by removing the bottom front access panel for any clogs to clean the error. Please get back to me if you have any other questions.

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!!!

Try a test cycle with the end of the drain hose placed into a bucket. If the dishwasher does not pump out then, call for warranty service (In the US, find a service provider using your zip code at http://us.lgservice.com/index_b2c.jsp or call LG at 800-243-0000). If the dishwaser does pump out into the bucket check the entrance of the drain. (if it is draining into a disposer, there is a knock out plug which has to be removed) By the way, that is not an OE error, it is actually a DE (drain 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.
