LG Dishwasher Error Codes

If you're looking for help fixing your LG Dishwasher, look no further! Our comprehensive LG Dishwasher error code guide will explain common issues, provide tips, and show you how to read your model's error codes.

CODE: IE 
PROBLEM: Not filling 
FIX: Check that the water supply cut-off valve for the dishwasher is fully open. Check the water inlet supply hose for a kink. Unplug the dishwasher, shut off the water supply and disconnect the inlet supply hose from the inlet water valve. Check the filter screen on the inlet water valve for a clog-replace the valve if the filter screen is clogged. 

CODE: OE 
PROBLEM: Not draining 
FIX: Check the sink drain or garbage disposal for a clog and clear any clogs you find. If the sink or garbage disposal drains okay, pull off the dishwasher drain hose from the sink or garbage disposal connection and check the end of the drain hose for a grease clog. Clear grease clogs from the drain hose. If the dishwasher uses an air gap, check the air gap for clogs and clear any clogs. 

CODE: AE or E1 
PROBLEM: Water leak detected 
FIX: Abnormally high circulation pump speed caused by low water level in the tub can cause the AE or E1 error codes. Water that leaks into the base of the dishwasher cabinet and trips the flood switch can also cause the AE or EI code. Unplug the dishwasher and shut off the water supply. Check the dishwasher cabinet base for water. If water leaked into the base, find and repair the cause of the leak. Water could leak from the water fill line, water inlet guide, drain pump, drain hose, door seals or sump. 

CODE: FE 
PROBLEM: Water overflow detected 
FIX: The drain pump automatically runs when the FE code is displayed. A leaking water inlet valve or a stuck relay on the electronic control board can allow water to fill the dishwasher constantly. To check for a leaky water inlet valve, unplug the dishwasher and see if the tub continues to fill with water. If it does, shut off the water supply and replace the water inlet valve because the valve is letting water to flow into the dishwasher constantly. 

CODE: tE 
PROBLEM: Thermistor (temperature sensor) failure 
FIX: Unplug the dishwasher and disconnect the wires from the thermistor on the heater. Measure the resistance through the thermistor using a multimeter. The meter should measure 11,320 ohms at 75 degrees (room temperature). Replace the heater assembly (which includes the thermistor) if the meter measures less than 1,000 ohms or more than 20,000 ohms. 

CODE: LE 
PROBLEM: Locked up circulation pump motor 
FIX: Unplug the dishwasher and check for an obstruction that's preventing the pump impeller from spinning. Remove any debris or foreign objects from the sump. If the pump impeller is clear, check the wiring connections on the pump and reconnect any loose wires. If the wiring connections are okay, unplug the wire harness from the motor and check the resistance through pins 1-2, pins 2-3 and pins 1-3 of the motor using a multimeter. The meter should measure between 8 and 20 ohms (resistance of the motor windings). 

CODE: HE 
PROBLEM: Heater failure 
FIX: This code appears when water isn't heating or when the thermistor (temperature sensor) detects that water temperature is higher than 194 degrees. If water inside the dishwasher tub is extremely hot, measure water temperature using an accurate thermometer. If the thermometer measures water temperature near 190 degrees, then you'll likely need to replace the electronic control board because a stuck heater relay on the control board is causing the heating element to stay on constantly. 

CODE: nE 
PROBLEM: Diverter motor failure 
FIX: Unplug the dishwasher and check the wire harness connections on the diverter motor and diverter position switch. Reconnect any loose wires. If the wiring connections are okay, unplug the diverter motor wires and check resistance through the motor using a multimeter. The meter should measure around 4,000 ohms of resistance. Replace the diverter motor if the meter measure infinite resistance.

Updated on 05/30/2020: As I stated in previous review this dishwasher has a manufacturing problem and LG refuses to do anything because it been too long!! It was made without railing on the bottom and thats why the basket keeps falling inside the machine. To refresh, they sent me about a year ago 2 new baskets, which of course didnt help. I dont know anything about machinery so I wasnt aware of the problem. A very nice problem resolver named Sean called and took pictures and told me what the problem was in the manufacturing and that he would resolve my problem and would be calling me in 1 HOUR. Well, its been 5 days and NO CALL!! Each time I have called customer service for an update they get snooty with me and keep giving me the run around. I WILL NOT be purchasing anymore LG products they do not stand by their products. For Sean who said he would help go to hell!!Original Review: LG makes an excellent washer with the exception of my lower basket. From day one Ive had a problem with it and LG sent me another one and it lasted less than 1 year. The bottom basket falls off the runner constantly and I am a senior that would prefer not to have to lift the entire basket filled with dishes to try to push it backside the washer. The model # is LDT9965BD and I bought it a Best Buy and Best Buy refused to help me. So Ive had this washer for 3 years and everyday the same problem. If I could buy another dishwasher I would. Also the things on the top and bottom move and I have to keep adjusting them and the utensil holder is a problem as it breaks apart and now is permanently broken. I could live with the others things. Its the bottom basket running off the rails everyday that is challenging. LG will not resolve this issue so I live with this aggravation on a daily basis.

Im another compressor failure customer getting completely screwed over by LG. They wont fix it. They wont Supply the compressor. Weeks going by. Out several hundred dollars of food and no fridge for 4 weeks. This is incredible. Paid $3,000... LG Imports should be completely blocked from the US. They should not be allowed to sell any appliances in the U.S. Theyre screwing over thousands of customers in the United States and Im sick of this. I also had an LG dishwasher that was defective and end of broke three times within a year to the point that I had to get a refund. I mean you know Im not alone here. There are thousands of people reporting the same issue. Its time that the U.S. government block LG from exporting anything into the United States.

I had a LG refrigerator which failed in just 6 years. I had a LG dishwasher which failed within 6 years. My sons LG refrigerator also failed just yesterday. The only LG appliance still running in my house is the clothes washer, which has rust showing around the top of the tub. I am holding my breath to see how much longer it will go before it too takes a dump. Then NO MORE LG anything in this house.

For the last 2 years I have not been able to use my dishwasher. The reason
For the last 2 years I have not been able to use my dishwasher. The reason is when it goes through a cycle it comes out smelling. I have had 5 repair man out here and they say there is nothing they can do - its the dishwasher itself. I paid over $1000 for this piece of junk. The only solution that they gave me was to go to a hardware store and get an item that you put into the dishwasher and its supposed to clean it. Needless to say I still cant use my dishwasher. When I bought all my appliances stainless steel this was supposed to be the best. I live on Social Security and its going to be hard for me to go out and buy a new one. It will not be an LG. I was literally washed the dishes before I would use the dishwasher. Now when I wash my dishes by hand at least I know theyre clean. I am very upset with this product. I have never complained to consumers but in this case I have to. Beware and if you do decide to get an LG make sure you have a very long extended warranty.

Purchased (4) LG appliances from Lowes. The dishwasher, model LDF7774BD has poorly designed racks... glasses and dishes fall over or roll around when you open and close the unit when adding additional dishes until it is full enough to run. The rack design is the big negative, will not hold as many dishes as our old one. We really did read the owners manual and watched the online videos which are not much help. Called LG customer NO Service and imagine they said they have never heard this complaint before... ha! DONT BUY LG DISHWASHERS EVER!! We will be returning the dishwasher to Lowes.

We purchased these items less than 3yr. ago.1st issue with dishwasher, secured contact with LG, would only replace defective part. Customers responsible for repair, only can use their factory-installers. It was cheaper to just replace with new dishwasher. Now the refrigerator is not cooling. There has to be some sort of being held responsible to their customers. Will never deal with this product again.

Have this machine x five years. Every year I have to do some type of repair
Have this machine x five years. Every year I have to do some type of repair. It has a 10 year warranty but nothing is ever covered by the warranty. This is the biggest fraud in the appliance business. I called LG to repair my machine that is neither washing nor drying, they sent a technician the cost was $300 down payment, never heard from them again. I called again the price was $411, which will cover one year repair minus $100 for coming out... This they insisted must be paid via credit card before they can come. They sent a tech out that was almost 4 weeks ago, no one has returned. I called only to get the runaround. No one will take responsibility. I cannot get any answer, cant get my money back and my machine is still not fixed. Company number (!) is High End Appliance $300. Company (2) General Appliance.LG is a rip-off company they do not stand by they appliance, they are dishonest, they do not honor their warranty, they do not satisfy their customers needs. They need to be shut down and be labeled thieves. 1800 243 0000 and 888 376 6825 and 201 623 8070 these are the contact numbers that have no information in regards to service. High End Appliance **.

LG French door frig purchased in 2007 has main board that was replaced twice in the first year. Then plastic parts crack and fall off door and veg bin holders. In October 2011 lights (120 watts) stay on, melts plastic and ceiling. Coincidentally, a law suit on that one and extended warranty to cover it. We will see. Bought an LG dishwasher at the same time. After 4 major repairs, it is now at the city dump where all these products should be. Wasted money/time repairing it. Spoiled food with light issue, not to mention the fire/burn hazard. Service is inept.

Even though it says dont rinse the dishes, just scrape them, this DW doesnt get the job done. Ive tried all kinds of soaps and rinses and I often have to hand scrape food off the plates and from inside glasses. I had a Sears Kenmore for its lifespan and they dont make anything like it. Disappointed, wont buy LG again.

We purchased an LG refrigerator and dishwasher at the same time. Happy with the refrigerator except for a problem with the freezer temperature. Then it started leaking. Had it about 2 years. Called the company who sent a repairman. The part was covered but over $1000 labor. Got a GE for replacement.

LG Dishwasher Model ldf7561st - Wow, wish I read these reviews before purchasing. We upgraded our kitchen with new appliances, all LG. To be honest, the other appliances have been OK for their purchase price... This dishwasher, however, has broken down after 2 years of normal use. After calling their very friendly customer service phone bank (that has no actual power to do anything), I was informed that, lucky for me, in order to repair the dishwasher, I had two options: pay $400 for a warranty or only $265 for a repair! What a deal on their product that couldnt handle 2 years of operation! So ridiculous - I will not purchase another appliance from this company again.

I bought this 2 years ago and had problems from the first load. The bottom slide out rack CONSTANTLY goes off track and can take 5-6 times to get it back on. Not an easy task when you are bent over and it is full. Dishes are always spotty, have tried every cycle and lots of different detergents and rinses. Everything is spotty and has a slippery feel to it. I end up using the rinse cycle only after doing a load and then they dont dry. More times than not I just hand wash the dishes. QUICKER, MUCH MORE ENERGY EFFICIENT AND DONE RIGHT. DO NOT BUY THIS CRAP.

I just had to replace a four year old LG dishwasher. This was the worst dishwasher I have ever owned. The rack system was poorly designed and engineered. The wheels were brittle and broke easily and very costly to replace. The control panel had to be replaced twice and although part of the warranty, it still was costly to replace. The motor was very noisy and recently stopped working altogether. I just purchased a Bosch dishwasher as a replacement and am sure it will be much better than the LG. This is the last LG product I will purchase. Poor engineering and poor customer support.

LG Microwave Mod# LMC0975ST/01. This microwave came with a very user friend
LG Microwave Mod# LMC0975ST/01. This microwave came with a very user friendly owners manual, that I like. Unlike my other microwaves this one has a hexagon rotating ring with six wheels for the glass tray to sit on. Plus the glass tray has glass bump outs on the bottom that fit into a bump out shaft on the microwave bottom. No more dislocated dishes falling or sliding off. This microwave has performed better than I expected and I have enjoyed using it from day one. It has all the usual programs like, Smart diagnosis, Auto cook, Auto reheat, Popcorn, Defrost, Power level, Cook time, Stop/clear, Start/enter, interrupted cooking.There is a beautiful sleek smoke glass full front panel that will match any decor. I found the tip section on what to use, or not to use, when it comes to microwave-safe cookware very useful. There is also a Child Lock safety feature, and the sound signals are very audible on this microwave. There is a clock, Kitchen timer and a easy to use, slide touch timer. Dont forget to read the maintenance section. I found it very helpful. Limited warranty for Canada or the USA, is provided at the back and there is also a 1-800 number plus their website.

Purchased my LG French door refrigerator in 2015. After the first year of owning it, the water lines froze up completely and started freezing the inside of my refrigerator. Service tech sent out to fix. Cost was more than what it should have been to fix a refrigerator that was just a year old. Then year 2 another service call and money spent out of my pocket to fix just to turn around and call them 7 months later. After more money was thrown into the refrigerator it was fixed only for a short time. In 2018, had another service tech come out and he could not tell me what the issue was. Call again, another service tech came out and we were told it was fixed. 2 weeks later I called again because the fridge had stopped Cooling yet again and again we lost most of the food inside. This time we were sent parts and the Tech that came out said it would cost over $1,000 for labor and we didnt have the parts that we truly needed. The service technician somehow broke the back panel of the refrigerator also. This was in July of 2018. The tech left the refrigerator taking apart and in pieces. Over a year later 2 October 2019, the appliance still sits in my house with the parts out of it and I have a non-working refrigerator. I purchased a small used refrigerator to get by until I was financially able to purchase another refrigerator. In 2015, we suffered a house fire which was a total loss so when I redone my kitchen I read reviews and thought I was making an informed purchase. Was I ever wrong!! My LG refrigerator isnt worth a dime and my LG dishwasher has had several issues in which Ive not even bothered to try to get fixed. I have just dealt with these issues myself also I have a LG washer and dryer. Luckily I havent had issues with it yet but I wouldnt be surprised if and when it does happen. With a name brand such as LG you would think they would do more for the customer. I finally spoke with LG again September of 2019, as I had heard they were covering certain aspects of French door refrigerators being fixed in the hopes of getting back my $2,500 refrigerator but still nothing has been done. I would steer clear of LG appliances in general. But more importantly I would make sure I stayed away from any LG refrigerators as they do not stand behind their product. This was the first time I had purchased so many appliances at once and lesson learned the hard way!

In October 2014 we purchased a very nice Stainless LG Dishwasher - Model: LDF7774ST. The first week we had it the motor went out. LG replaced the dishwasher. Back in January of 2015, the so called quiet Dishwasher started making a lot of noises and had to have the dishwasher serviced. Now, the LG dishwasher will not drain. We have cleaned out the filter and the drain and nothing works and now have to have it serviced yet again. Three times in six months on an $800 dishwasher? Will never purchase an LG dishwasher again.

We bought an inverter direct drive about 5 years ago from Home Depot and shortly after we had it, it did not clean very well. We called and they came out and changed the pump and it worked for a short time. The second time they came out they looked at it but did not much seem to care. The dishwasher has not worked properly since we have had it. The dishwasher that we got rid of and was way much older cleaned better on its last leg than this one did. Do not buy LG products.

I have been loading home dishwashers for over sixty years and my LGF7774 is the worst, and I must say, nearly impossible to load effectively. Because it doesn’t seem to be designed for actual dishes, it takes longer to load, as I have to move things around constantly to get them where they will actually get clean. The top rack areas for glasses seems to be slanted wrong and are the wrong width. As a result the glasses often fall over and break as I’m closing the tray. The bottom rack is even more frustrating. Those prongs that flop down to accommodate (what?), pans perhaps, may have seemed like a good idea to some engineer, but in use they plop down whether you want them to or not. The bottom of the lower rack could also use some redesigning. I have many square dishes and have to be over-cautious about seeing that the corners don’t extend downward where they will interfere with the spray arm.The dishes washed appear to be clean, but don’t smell clean. I’m asking the world of manufacturers, “If the user has to rewash things, or wash them before using a machine, how much water and electricity is that saving? And if I cover the food-left-on smell with a scented rinse does that make the dishes cleaner?” In fairness I must add that I just discovered that it has an extra rinse cycle and am at the moment trying that one out.

We purchased a LG dishwasher model no. LDF8764ST ($800) four months ago and after using it ONCE, it stopped working and would not power on. I was not able to return the dishwasher where purchased and was informed that I had to deal directly with LG. I called LG and was scheduled a visit from a repairman. The repairman never showed up (took time off from work), so I again called LG. I was informed that the repairman had not received the ticket from LG. I indicated that since the product was defective (it worked once) and I was not comfortable risking taking another day off from work and having the repairman be a no-show again, that I would like the product either replaced or receive a refund. I was told that my only option was to reschedule the repairman. I declined and purchased a different dishwasher from another manufacturer that has worked like a charm since it was delivered/installed. This has been the worst product and service I have ever encountered.
