LG Dishwasher Error Code E1 – How To Clear

LG Dishwasher shows E1 error code, what does e1 mean? I have a 2 year old LG dishwasher. It has recently been showing the E1 error fault code. Can you tell me what this means and how do I fix it myself? Do I need to replace a part or clean an area of the dishwasher to clear the code and reset the dishwasher? Please help as the dishwasher is no longer under warranty.

LG Dishwasher Error Code E1LG Dishwasher Error Code E1 – How To Clear? – How To Fix?

LG has programmed in the E1 error code to indicate when the drain pump is running, it is not receiving the back pressure it needs. This is most likely an indication that there is a water leak in the draining system. See below for what to check to fix the E1 error…

An E1 (or AE) Error Code identifies there may be a leak in your LG dishwasher.
A leak may be caused by:
1 – Improper installation of the dishwasher.
2 – Using too much or the wrong detergent.
3 – Dishwasher door leaking.
4 – The dishwasher was not loaded correctly.
5 – Faulty sump motor.
6 – Faulty float assembly.
7 – Leaking sump assembly.

NOTE: For more detailed info on troubleshooting and replacing parts such as the Sump assembly, Float assembly, see the chart below.

LG Dishwasher E1 Error Code TroubleshootingLG Dishwasher E1 Error Code Troubleshooting

Check these parts and areas of your LG dishwasher to troubleshoot and clear the E1 error code:

1 – Dishwasher Drain Hose Installation
Drain hose outlet installed lower than the base of your dishwasher?
– Drain hose outlet is installed lower than the base of your dishwasher may cause early draining.
– This can be the cause of the E1 error code.
– The height of the end of the drain hose must be over 10 inches from the bottom of the dishwasher.
– This is to prevent water from being siphoned from the tub too early.
– Check the drain hose for damage that may cause leakage.
– Replace the dishwasher drain hose if it is found to be damaged or leaking water.

2 – Improper Dishwasher Detergent Use
– The wrong detergent can cause excessive suds.
– Check if you are using the wrong detergent. (Not to be used in automatic dishwashers)
– If using the wrong detergent, your dishwasher can fill with suds.
– If the dishwasher has excess SUDS, your dishwasher cannot wash or rinse correctly.
– E1 error code will appear when there is too many suds or excessive suds.
– Only use a dishwasher detergent that is made for automatic dishwashers.

3 – Dishwasher Door May Be Leaking
– Check if there is water seeping through the dishwasher door.
– Check for any door seal rips or tears around the door seal.
– If you find that the door seal has any type of damage, remove and replace the door seal.

4 – Dishes In LG Dishwasher Are Not Correctly Loaded
Are you loading your LG dishwasher with large items such as oversized pots or pans?
– The way the pots and pans are positioning can cause the dishwasher to retain water that fills the dishwasher.
– This can cause the dishwasher to error out and think that there is a leak.
– Make sure all large pots and pans loaded inside the dishwasher are positioned in the racks correctly.
– Position the large pots and pans so they do not hold any excess water.

5 – Faulty sump assembly, Float assembly.
Remove and replace the sump or float assembly if you find that is the cause of the E1 error code.

I had the E1 fault on our LG dishwasher. Nothing cleared it until i did what Jason further up had done. I tilted the dish washer all 4 ways and it was fixed.

LG direct drive Dishwasher about 5 years old. Error code —
Drain Hoses are clear, no cloughs, unplug can’t clear or run a washing cycle.

We have tried to remove the E1 code after fixing a leak in the door seal but it comes back.


4 Peter Chandler December 27, 2017 at 1:42 pm

OK I have had the same problem clearing the E1 error code. Tilting the machine back and forth did not work the first time. I tried again this time pulling the dishwasher out further and it worked. The angle is definitely the key.

We purchased our LG dishwasher about 4 years ago..
It is now showing an error code of E1, we have checked for leaks and found none.
All the above test have been done but no parts have been replaced as if yet.
The dishwasher does complete the cycle but does not chime when cycle is complete, the error code is v o.j. sable after the cycle has completed. Any suggestions

I can’t get my LG dishwasher to clear.
I have tried unplugging and when I pulled it out it reset and ran a fast cycle.
When I put it back in the space, the error code came back on again.

Had to replace garbage disposal that flooded kitchen cabinets.
LG Dishwasher was running and was turned off, now LG dishwasher gives code 03.
It sounds like it is trying to run but no water comes in and yes the water is on to washer.
We rinsed the filter so it is ok.

We had a blockage in our drains which cause dishwasher not to drain. It has now drained but the e1 code is still flashing and the dishwasher is running but no water or anything is working. Just can hear it working


9 Jason Moore August 7, 2017 at 12:02 pm

Hi Nicci – we had the same problem. It is apparently caused by your wastewater not escaping via the drain, and flooding the dishwasher which activates the alarm. To clear the alarm, we tipped our dishwasher to one side, which allowed a small amount of water that was trapped in the dishwasher, even after the drain was cleared, to escape. Hope this helps

After hours of Googling this E1 error code problem, I found Jason’s tip and it worked! Just pulled out the holding screws, slid the dishwasher out a foot, tipped it forward and backward, and the error cleared. Ran a QUICK cycle for about 1 minute with the drain hose in a plastic garbage can to see the dirty waste water come out, and success. If you have a clogged drain and water flows back into the dishwasher you’ll get this code, and this is your FIX! Thanks Jason – you saved me a lot bigger headache.


11 Jerry November 2, 2017 at 11:33 pm

Followed Jason’s and Matt’s suggestion. Pull unit out, tipped forward and backward 45 degrees and now the code has cleared. LG wanted $370 to come out to fix it.

12 David Buell May 24, 2017 at 4:19 pm

I have unplugged The unit overnight and turn the power back on immediately it says E1 I don’t even have to turn the power button on it has an audible tone to it and flashing all the lights on the front of the unit. The unit was running at the time we lost power in the house and when the power came back on that error code was present. The dishwasher pumped all of the water out of it into the sink via the garbage disposal my son forgot to run the garbage disposal all with stuff in it so all the water wasn’t draining so it filled the sink up. So I think what happened was water siphoned from the sink back into the dishwasher . That’s probably why it got the E1 code now I check the hoses I took the pump apart there was nothing clogging or leaking the pump works it drains continually runs it will not turn off unless I can shut the breaker off. If I pour water into the unit with a tub of pumps the water out like it’s supposed to but it doesn’t stop pumping it stuck in a mode.


13 Jason September 1, 2017 at 6:22 pm

I have exact same problem. Did you find an answer?


14 Mike November 25, 2017 at 6:41 pm

I have the same problem as well, any luck?


15 Don May 13, 2017 at 4:22 pm

I cannot seem to get the error code ae to reset I have checked all areas of my dishwasher can not find any leaks the pump keeps running as soon as I turn my breaker back on, lds6040st direct drive


16 Tiz April 15, 2017 at 6:43 am

I’ve had this LG dishwasher for 3.5 years and never had a problem.
Now it keeps giving me an error code AE which is water leakage.
I have checked absolutely everywhere and do not have any water leakage.
I just don’t know what else to do.


17 Andrew Frazier October 30, 2017 at 3:51 am

I have same issue and cannot reset dishwasher. It just stays on and will not shut off even after turning off electricity and turning it back on.
