LG Dishwasher Error Codes – How To Clear Errors







If you have a newer LG dishwasher, you may see error codes show on the digital display. An error code is the computers diagnostic system telling you there is a problem. The specific error code will tell you what is wrong with your dishwasher. It works in the same way as when you have a light show up on your cars display panel telling you a potential problem. An error code on your LG dishwasher can help you how to fix the problem yourself if you can identify the code. Usually it is a simple task of resetting something, but occasionally, the error code will tell you that a certain part is bad, clogged, or possibly jammed. See below for all the different error codes your LG dishwasher may display…

LG dishwasher error codesLG dishwasher error codes

LG Dishwasher OE Error Code
OE error code on the dishwasher display is telling you that the unit is detecting a drain issue.
This is usually from clogged food or possibly an installation issue.
If there is water at the bottom of the tub in the dishwasher, try a DRAIN ONLY to drain the water.
To complete a DRAIN ONLY, look at the buttons on the display and you will see a CANCEL & DRAIN under 2 buttons. Press those 2 buttons at the same time to start the CANCEL & DRAIN cycle. (See image below)






LG dishwasher panelLG dishwasher display panel

If you do not have a CANCEL & DRAIN option then simply start a cycle, let it run for 45 seconds and then turn the dishwasher off. On LG dishwashers, the first 45 seconds of a wash cycle is actually draining.
This should clear your error code OE. If not your LG dishwasher may require service.

LG Dishwasher LE Error Code
LE error code on the dishwasher display is telling you there is an issue with the motor’s proper operation.
The LE error code can be fixed by doing the following steps…
1 – Press power button and turn dishwasher off
2 – Turn the circuit breaker or unplug the dishwasher for 10 to 15 seconds.
3 – Plug the dishwasher back in or turn the circuit breaker back on.
4 – Press the power button to turn the dishwasher on.
5 – Start a new cycle and see if that clears the error.
This should fix the error code LE. If not your LG dishwasher may require service.

1 – Press power button and turn off your dishwasher.
2 – Unplug the dishwasher for 10 seconds.
3 – Plug the dishwasher back in.
4 – Press the power on button.

My LG dishwasher LDF7561ST has 2 lights on front of door top right – one blue & one yellow. Yellow comes on when started & again at end but goes out after a minute or two at start & end of cycle. Never did before. Have cleaned filters do not know what else to do & manual not helpful. Your assistance is appreciated.

I have a LG LDF7774ST dishwasher that I bought used. It worked fine the first couple of times, but now I have an AE error that I cannot clear. It did leak water and suds on the kitchen floor, but nothing in the basement. I don’t know which circuit breaker it is, so I shut of the main and it is still showing AE and trying to do something. Can I force a shutdown somehow? I am sure it will burn itself out at some point.

Beth, we struggled with AE error code as well with our DW under warranty.
We had two different repair companies out – and they replaced all of the ‘guts’.
Finally had an official LG Repairman visit, he took one look at the situation and said “you’re using too much soap”.
We started using only one tablespoon or so of soap (do not fill the Reservoir)!
Haven’t had the error code again.

Eric Wicks – Thanks for the input!
Super bummer that you had to have 3 visits before someone told you that “you’re using too much soap”.
Oddly enough, I came to that same conclusion after reading some on line information from users and LG.
I had suds and water on the floor in front of the unit, but no water under it or in the basement.
I had lots of suds inside the unit.
My unit was also cycling trying to drain, but I’m thinking maybe the sensor was reading the suds, rather than actual water.
Once I cleared the inside of suds, and soaked up excess water from the drain with a towel, the unit stopped trying to drain and I could finally turn it off and stop the racket.
I ran it without any detergent twice after that with no issues.
Lesson learned!

I have a FE error code on my LG LDS5540ST dishwasher…from what I can read it’s an overflow error…but when I open the dishwasher when the error code appears, it’s not overfilled whatsoever…but not dry either…should I replace the water inlet valve?

Sylvain,
Be sure the LG dishwasher is getting the proper amount of water.
Be sure there is no clog or blockage in the water line.
Make sure the water valve from the wall to the dishwasher is FULLY OPEN.
Check the water inlet valve to be sure it is getting the proper power and that all wires are secure.
Also…Check that the float switch is not causing the OVERFLOW error.

LG LDF8072ST
I had an error code for not draining. I replaced the drain pump, that code is gone and pump works fine now.
Now, when starting a wash cycle the machine begins by draining first, then it fills with water, and then nothing else happens, no sounds of motors or wash arms turning.
While this is going on, the timer is still counting down normally, the indicator lights blink through there respective cycles and when time runs out it emits it’s normal musical tune.
Without an error code, or a diagnostic chart, I’m stuck.

DIY Project Help Tips 14 DIY Project Help Tips June 20, 2016 at 9:59 pm

Pam,
LG Dishwasher “IE” blinking error means the dishwasher is not filling with water properly.
But in your case, when you say the dishwasher turns on by itself, do you mean the lights on the panel come and flash 1E LE, lE, or the dishwasher is flowing water and washing a cycle all by itself??
You may have an issue with both the water inlet valve and the door switch.

Check to be sure the water supply valve is open.
Check to be sure the water supply line isn’t kinked or clogged.
Remove the water supply line from the dishwasher and run water into a bucket to test the pressure and flow of the water.
If all of these check out and you have good water pressure and flow to the machine, you should replace the water inlet valve.

My LG dishwasher has the error code tE.
How can i fix it or do i need a service technician?

DIY Project Help Tips 16 DIY Project Help Tips June 9, 2016 at 9:37 pm

Leanne,
LG dishwasher error code tE is a THERMAL ERROR.
You will need an ohmmeter to check the value of the thermister.
The thermister is located on the heater assembly mounted to the sump/motor.
Disconnect power to the dishwasher before attempting.
The thermister should ohm out between 11-14k ohms.
If the thermister checks to be okay then you may have a wiring harness issue.
The thermister harness runs through the door area and has been known to cause issues.
If the wiring harness & thermister check out to be okay you will need to replace the main control PCB.

Derek,
LG Dishwasher Error Code = FE
WATER OVER FLOW ERROR – Water continues to enter dishwasher
The washer is overfilling due to a faulty water inlet valve.
The valve may be repaired but may need to be replaced.
If you replace the water inlet valve and the error code continues… there may be an issue with the main control board.

The safety switch as in the GFCI or the main Circuit Breaker?
Have you tried plugging it into another outlet?
If your LG dishwasher trips the breaker, something in the dishwasher is shorting it out and must be troubleshot to find the cause.

How do I fix an error code of nE on my LG Dishwasher?

Reply

DIY Project Help Tips 22 DIY Project Help Tips April 11, 2016 at 10:09 pm

Shari,
This LG dishwasher error code nE may mean an issue with the MICRO SWITCH. This micro switch tells the Board the position of the Motor. The motor and switch redirects wash water from the lower wash arm to the middle and upper wash arms and back every 90 seconds. If the main board does not receive confirmation that the position of the micro switch has changed, it will trigger the error code “nE”. Install a new micro switch and possibly (if installed wrong) add a stainless steel flex water line.

My LG dishwasher has code AE. I think I found that means water leak but there is no visible water and unit runs continually and only turns off by turning breaker off.

Amanda Anderson,
Yes the AE error code for an LG dishwasher is an indication of a leak. You may have a bad flood sensor if the unit is actually not leaking. If the dishwasher continually runs, what is showing on the control panel? Flashing lights, other error codes? When you say continually runs, what component on the dishwasher is running constantly, the pump, water fill, etc?? Can we have the model number of your LG dishwasher?

Model # is LDF7774ST. Not sure what is running, just hear a constant motor noise, possibly the pump. Constantly blinks with code AE and green and blue lights both on. If I hit power button to turn it off it immediately turns back on. We were quoted between $300-380 by LG for repair. Any idea how much a flood sensor costs? Thank you for taking time to answer my questions.

Here is the parts manual for your LG Dishwasher. Your issue may be the pump is constantly running because of a pump issue, a board issue, or sensor. All parts you may need to replace after further troubleshooting is in the manual we have linked to. We would recommend taking the machine apart and do some further testing before ordering any new parts.

We have been experiencing the same AE error code with the blinking lights and chiming sounds. It seems to me the ‘sound’ is the sump trying to drain water, but there is none in the unit (this occurs at the end of the cycle, dishes are clean, but sometimes have soapy residue, so final rinse did not occur). We had one repair company out who replaced the main board. Unit worked fine until June when the AE error code occurred again. Only thing that seems to correct it is to turn off the breaker and wait 3-4 days. We had another repair company come out, since the first one became ‘too busy’ to help us. This company ordered two parts, one that goes on the left side, and a complete sump replacement. After wrong parts delivery and attempted installation, we have both parts installed. Still get the AE error code. The repair company told me to remove the flooring that rubbed/touched the bottom of the sump hose, which I did. The unit works once after each repair attempt, and back to the AE error code (probably because the unit is tipped and a small bit of residual water is drained out). Any thoughts?

I have an lg with the IE error code. New water supply line, new water supply valve, unit fills and then stops and codes. The float is 1/2 way up the chamber when this happens. Help!

DIY Project Help Tips 32 DIY Project Help Tips February 10, 2016 at 8:21 pm

Paul Brohman,
IE error for LG dishwasher = Water Inlet Error
If you have replaced the water line and water inlet valve…
– Check to be sure the water supply valve is FULLY open.
– Check to be sure the water supply line is not bent or clogged.
– Remove the water supply line from the dishwasher and run water into a bowl to test the pressure and the flow of water.
If the above checks good, make sure the water inlet valve is installed and wired properly. You may have a faulty new water inlet valve.
Where did you buy the water valve and is it OEM?

The valve is OEM and it works. I have watched the water enter the inlet assembly. (flow switch and 2 float switches) How deep is the water supposed to be before the inlet valve closes?

DIY Project Help Tips 34 DIY Project Help Tips February 11, 2016 at 6:51 pm

Paul Brohman,
The water should reach the float and shut off the water. The float/float switch will determine the depth of the water. Check to be sure the float moves up and down properly with the water depth and that the float switch is operational.

I have an LG dishwasher and got the HE error code. I pulled the unit out from the cabinet and on the left side is a plastic box with 2 floats that rise with the water and touch these electrical points to start the heating process. The plastic box was full of “gunk” (old food particles) I cleaned it out and now the dishwasher works great! Just passing this along to anyone else who might have the HE error code caused by gunk in that little plastic box.

Reply

DIY Project Help Tips 37 DIY Project Help Tips October 23, 2015 at 6:10 pm

Khalid,
For the LG dishwasher with the HE error code:
The HE error code means a problem with the water heating circuit. Unplug the dishwasher for 30 minutes to let it cool. After 30 minutes restart the cycle. If the error comes back check the heating element for continuity. Also check the wiring harness for damage. If the element shows infinite resistance remove and replace it.

For the Samsung dishwasher with the IE error code:
The 1E Error Code is caused by a blockage which prevents the dishwasher from draining. Clean the Filter System and the Sump in the dishwasher.

DIY Project Help Tips 39 DIY Project Help Tips October 12, 2015 at 7:17 pm

Chris,
LG dishwasher error code E1 means a LEAK ERROR. Excessive pump motor RPM due to some water leakage. When the drain pump on your LG dishwasher is running it is not getting the back pressure it should. This indicates that there may be a water leak in the draining system. Check all the hoses and connections. Also, be sure there is a proper loop in the drain hose to prevent it from siphoning. If you have no leaks and there is no water leakage, the drain pump is most likely bad and needs replaced. Test with a multimeter to be sure.
