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 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 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.

Same problem, LG Dishwasher E1 code which cannot be cleared. First and foremost this is a hazard. In my case the DW randomly turned on and attempted to drain residual water, and could not be powered off permanently without turning off the breaker. I could have been out of the house when this happened, and at the pump runs out water to drain and sucking air. I can only imagine what might happen over the course of several hours and the pump probably overheating.
I read through all of these posts and after several attempts of cleaning the float sensor and tilting the washer forward the drain off what ever water was trapped, I grabbed my trusty wet vac and put the nozzle as close to the drain holes, covered it a towel to aid in the suction, and just let it vac for about 30 secs. I then immediately turned the breaker back on and the E1 code was cleared.
Thanks to all respondents for their posts, it helped point me in the right direction.
I opened my LG direct drive dishwasher with 16 minutes left on the cycle. It beeped at me and now I have an e1 error code that won’t go away
I replaced the inlet pump because it was leaking. Since I replaced it, I get an IE error and the dishwasher doesn’t fill up. Put back the old pump and no errors. Ordered new inlet pump but IE error persists. Do I need to reset anything or do you have any suggestions?
I had the E1 error and nothing would clear the code and pump kept running. It has been running good for like 6 years. I pulled out the unit and tilted it forward to see what would happen. When I did this a brown puddle formed on the right side. Seem that the coffee machine above it had overflowed and was causing the E1 error. By tilting it forward the coffee came out and the error is now resolved. Thanks All
I had the e1 error code and like many was able to pull out the dishwasher, and tilt to remove the water accumulating at the bottom of the dishwasher to reset the error code, only to have it return days or weeks later. The remove and tilt procedure did reset the error code every time. I was finally able to determine what was going on. After the last time I encountered the e1 error code, I pulled out the dishwasher and located the float sensor located on the bottom, right side of the dishwasher. The float sensor was sitting in water that had pooled into a pan where it was mounted. I mopped up the water in the pan with paper towels and that reset the e1 error code. Two black tubes led into this pan and appeared to be designed to collect water from the left and right edge under where the door meets the basin. The inside of the tube coming from the right side was dry, while the tube on the left side was wet. I can only assume that water was leaking somewhere on the left side. I had previously replaced the door seal, but that didn’t permanently address the issue. I reinstalled the dishwasher as I normally have and noticed a couple of things. The dishwasher was level side to side, but was not level front to back and was tilted slightly forward. Also the gap between the door and basin was different on the left and right side (put a flashlight in the dishwasher to sight this gap). The installation guide indicated that it should be level and the gap the same. I replaced the clips at the top of the dishwasher, since they were worn from removing so many times, and made sure the dishwasher was firmly held in place, while making sure the gap was the same and the dishwasher was level front to back and side to side. This seems to have solved the problem. I’ll give it a couple months before claiming the fix permanent.
Wow, E1 Error, tries the tilt forward. Nada. Tilted tonthe right. Nada. Switch off and on again while tilted to the right. Boom! Thank you so much for whoever gave this trick
