- LG LDT7797BM dishwasher issues. One possible reason you’re receiving an AE and or an OE error code. You can find tons of possible causes and fixes researching the model online but I never saw this cause or fix.
Hope it helps someone out there.
You Sir made me look good in front of my wife and kids. Due to not having to spend money on a professional to fix our dishwasher, my family now will put those funds towards a statue of me. It will be placed in our house to honor my ability to fix things we never thought I’d fix. As a member of the man council of Arkansas, I hereby make a motion to give you your own holiday. You rock. Thanks for posting such a great and helpful video.
I second this ☝
@@justenhansen fantastic video it worked perfectly. Thank you very much.
Your out of the dog house! ;)
Agreed just did this fix last night actually on my kenmore but it's the same dishwasher. Wife was soooo happy!! Thanks for the video.
I don't know the model, I just saw an AE error, and watched your video. Just so you know I'm 67 yo widow, who had a husband that could fix anything. I did it with your help. Thank you Lord Bless you and your family.
We need more people in the world like you buddy. And I mean that God-bless you in your family
Even a year later and a different model, this video points out the grease buildup, which is what got me. After looking and finding no leaks (except the little bit in the tray). I did notice the scum in the air lock and rather than wait for service (after 4 sinks full of hand dishes TODAY), I gave the clean out a shot. I alternated dish soap and white vinegar and about 30 minutes later, we are back in business. Thank you!!!
Sir your advice and instructions were PERFECT 👍🏽 I have been looking at the debris in that chamber since yesterday wondering if that was culprit……you completely clarified that…….why you don’t have a RUclips channel making millions is baffling…… 🙏🏾
2 years later and you just saved me an expensive repairman visit (and probably a replacement suggestion). Thank you thank you thank you so much!
So much more helpful than any explanation I've seen from any manufacturer! Saved my weekend. Thank you sir.
Clear and concise instruction. This helped me out even though my LG Dishwasher is a different model. The seal around the round air vent that is inside the tub on the left side, was leaking water back into the tub, which in turn kept activating the drain pump. I imagine after the pump gets activated after a wash cycle enough times, the AE code gets triggered. All I had to do was remove the seal, clean it and reinstall it. Problem solved.
Another success story! My sink backed up so I plunged it. My LG dishwasher immediately went into AE error mode and could not be reset. I hired a repairman for $139 and he concluded that need a new drain pump at a cost of $450 installed. I considered what led to the AE error and said “no thanks”. Stumbled across this video and problem solved. Thanks OP!
MY HERO!!!!! Dishwasher was leaving food particles on glasses and top rack didn't ever seem to come out clean. Replaced mesh filter and still dirty dishes. Turns out the float was clogged and wasn't allowing enough water into dishwasher causing it to drain early. My husband was CONVINCED the problem was due to me not replacing the filter correctly and I was very pleased to prove to him that that wasn't the case!!!! Thank you so much!!
God bless you, sir! With your little video, I fixed my own dishwasher BY MYSELF and saved a service call!
I followed all of your steps earlier today, now I am washing a load. The blockages was exactly where you said it would be. You saved me money on repair costs and possibly buying another dishwasher. Thank you much- By the way, you were more help than LG :)
One of the best RUclipss I have watched. Though not doing it as he explains, the explanation is very very clear... Am now a certified dishwasher troubleshooter...
Thank you for posting this. I NEVER comment on RUclips but this was a lifesaver for me on Father’s Day no less. Thank you.
You’re welcome and I hope your Father’s Day turned out excellent!
You, sir, are a saint. Had AE come up the day after my son was born. Came home from the hospital to suds all over the kitchen floor. After LG's useless troubleshooting (recommended to call a tech) I found your video and this was exactly the problem: grease gummed up in the channels. Your level of detail was perfect and instructions were clear and simple. 2 hrs from water on the floor to a fully operational dishwasher.
Thank you, thank you, thank you!
I got the same code 2 weeks after my first child (son) was born. I went through the usual Office Space argument with the machine "why do you say there's a leak when there IS NO LEAK??" This is probably the issue with my dishwasher and I'll know after his second pediatric appointment in the morning, after my nightshift making sure he's still breathing between hangry cries throughout the night! Thank you for this upload, sir!
BOOM! Worked great! Ended up using boiling hot water and dish soap to get my vent clean, but point is this video saved me $$$$$. THANK YOU!!
Worked perfectly!!! Thank you! We were going crazy and we definitely didn't want to shell out a couple hundred to have someone service it for us.
I don't want to hyperbolize, but this video is the most singularly helpful piece of human creation since the works of Isaac Newton. Thank you thank you thank you.
Thanks for the video. This is exactly what was wrong with mine as well. Helped narrow down the issue pretty quick, with great pointers for removing, cleaning, and re-assembling. Thanks!
Works with other similar models as well. Stubborn washer literally wouldnt even turn on once the AE code struck. Fixed with this guide and saved a day off of work waiting on a warranty repair. Thanks!
Came back from vacation to an error. Found this was the problem and fixed it based on your explanation. Thank you for the help!!
Excellent video that solved my problem perfectly. My drain had backed up with a sewer blockage on the sink line. Using a plunger to try to clear it just pushed debris back into the dishwasher, causing the AE code. Your video took me quickly to the sensor and had great suggestions for cleaning it. Thanks very much.
Thank you, this will help immensely with an elderly friend of mine. He's getting a 1E code. He has very iron ritch water. The impeller under the sensor is clogged. Now you have shown how to get this part of, it will be easy to clean. Thanks again!
Thank you, JP. Your guidance was right on. Your confidence let me know that I could do it. Took about an hour, but success. Thank you.
Like all the other happy people, you are bang on! Saved me from purchasing a new replacement. I am very handy also, but it is from people like you who take time to share that this community help each other out! To add to this post, I first used hot water to loosen the debris. Then poured a mixture of vinegar/water and baking soda inside. It really helped to break up the buildup. Finally as you said, shake it like crazy to agitate the buildup.
Thank you so much for posting!
Thank you so much! This was our exact problem and you were the only place that directed us how to fix the issue. Good explanation of everything.
Yet another success story. Your video was the key to fixing my dishwasher. It's amazing that the troubleshooting steps from LG say nothing about this. Thank you so much!
I found a leak on the lower left hand side, just like you mentioned. I pulled it out and it had the exact same fat clog in the air gap assembly. Excellent instructions: My hat's off to you. You're a scholar and a gentleman.
Thank you! I’m a single mom and was able to fix it on my own thankful for you and your kitties
JP, major Props to you! this solved my issue on a LDT5678ST. THANKS!!
Brilliant video! Thank you! Thank you! For our LG LDT6809SS/00, we originally had an nE error code (leak) and, after removing the toe plate and sound proof padding, we discovered that water was leaking from the nut of the braided metal water inlet line at the bottom left corner of the front. of the machine so we unscrewed the line to remove it, applied a couple rounds of new teflon tape to the threads fo the brass receiver on the machine and screwed the water line back on snuggly, and that solved that one.
Then, another nE code. After emptying the dishwasher of its shelves, cutting the power at the fuse box and outlet plug under the sink, shutting off the water valve under the sink, taking off the water line the waste tube from the disposal under the sink, with bowls/towels to catch any water/gross stuff, I pulled the machine out into the kitchen along with its 3 loosened lines. This time I lay down on the floor on the left side of the machine and watched the underneath for a couple mins of the clean cycle (2 mins/1 : 22 mins) and discovered a leak around the vario motor. So we soaked up the little bit of water from the black tray/bottom cover, let the machine dry for a bit, and turned the machine upside down (you may be able to just lie it on its side, but we found it easier to work with the machine upside down. Since you can't easily take off the black plastic bottom cover of this model (uggh), I wormed my hands into the various openings to take off the wire harnesses to the vario motor and relay switch, unscrewed the vario motor to bring it out and tested its ohms and the switch's ohms with a multimeter. We got proper readings from the relay switch, but got an infinite reading on the vario motor as opposed to a @4K ohms reading, so we ordered a new vario motor (Dishwasher Diverter Motor 4681ED3001D) for $20 from Sears Parts that got the proper ohms reading. Once installed and machine turned right side up, with lines reattached and power on, we ran the cleaning cycle again.
Another nE code within 2 mins. After seeing a second leak from the newly installed vario motor, we ordered a new grommet with washer (AHR73669802 Shaft Assembly) for the vario motor from Sears Parts for $9 and installed it on the new vario motor. Done. No more leaking! Do yourselves a favor and just order the grommet and washer to place on your new vario motor before running the machine.
Then another (!!!) nE code after the first hour of the cleaning cycle (60 mins out of 88 mins). So lying on the floor and looking underneath again, I noticed some water with a tiny bit of residue particles in the bottom cover tray compartment underneath the second drain tube/water compartment of the fill funnel assembly (Dishwasher Fill Funnel Assembly AEC74337401) and then came to your video for the fix! I know your video covered codes aE and oE, but it really helped our issue, too. Thank you so much! I think we may have a functioning dishwasher again! And we have saved sooooo much money!!! YOU ROCK!!!
Plus, your kitties were an inspiration! Very fitting that the one on top of your washer was cleaning! :)
I just realized who you sound like to me - Ted Lasso! Especially when you say: "for some silly reason", "shake it shake it shake it shake it", the sound you make after "clockwise", and "peace out". Made me smile! You could voice overs for Jason Sudeikis. :)
Thank you for making this video. Followed your steps to troubleshoot this and it is up and running. Not the same model number but all of the same components.
Thank you for posting this video! Looks like I had the same problem with dishwasher that is 3 years old. This is my first LG and have never had a problem like this with washers in the past.
I appreciate your willingness to help others, and I hope all is well with you and your family!
Same as me, almost 3 year old LG, seems like that is the lifespan of the part without service.
Clearly not the lifespan of the part since it works after cleaning. It's basically poor engineering with waste water disposal, but if the part still works after cleaning then it's not lifespan. It's like saying the filter in my shop vac has a one bedroom of drywall installation lifespan because it clogs and needs cleaning, which it is designed to do.
This is my first LG dishwasher and it's purchased 2 years ago, but unsure of manufacture date. I have LG fridge and washer dryer combo that are on their 6th year running great, but was curious how the dishwashers would blunder like this.
Stumbled across this video as I was about to punch a hole in the wall due to frustration…seems to have cleared the error code and so delightful seeing that gnarly build up come out. Hoping this fixes the problem! Thanks!
Thanks for the video. I was having the same AE error code. Pulled out my dishwasher and had the same fatty food build up. Cleaned out the air gap panel (took a while) and fixed the issue. Another $400 saved!!
Thank you so much sir. I was stumped as to how to fix this AE code. Appliance repair guys are booked out for months here, so i was trying to fix it myself. Mine was super clogged with grease. Took a while to clean out, but i got it eventually. Now im up and running!
Glad that I've found your video. My LG received the E1 error code and the draining pump kept running despite several attempts to reset the code by power disruption. It works again after cleaning the air gap assembly. Thank you for the video!!
This helped my son and I fix our dishwasher last night. I cannot thank you enough!!
Just fixed my dishwasher! Big thank you for sharing the solution step by step!
This video is perfect! Cleaned the air gap assembly. It had food parts in it due to a plumbing issue under the kitchen sink drain. It fixed my AE error code. Thanks for posting!
I saw that on mine. I had to mop up the water down in the pan that cleared the AE code.
This worked great for me. I unclogged my garbage disposal and it apparently caused the backed up water and gunk buildup to be trapped in that pocket you described. Followed all of your steps and the code went away. Thanks a lot!
Thank you for taking the time to put this very helpful video together. It solved my issue and save my family a bunch of money. Cheers
My friend your video saved the day for me as well. I was stuck in a AE loop after the kitchen was flooded with water. We recently moved and the prior owner never cleaned the drain and we were felt the pain of the overflow situation. Also, TIP - I found some boiling water with some dish soap allowed me to clear the fat in the air gap.
Just a word of warning. My valve was clogged far more than the video. I had purchased a new part and installed that, but then I figured what the heck and tried to clean the old part. Dawn had minimal impact. Hot water, as in from the coffee maker did help, and I was agitating the part in all cleaning methods. Finally I tried brake cleaner. It distorted the black plastic part of the valve .. so don't do that. The exposure to the brake cleaner was less than 1 to 2 minutes as I followed up with a hot water flush ASAP.
I've had mine for 5 years so really, what's a new $80 part every five years? I have decided that if I am going thru the efforts of replacing this I will always use a new part. I don't want to make this into a yearly project 😆
Best of luck with yours, everyone and a BIG thank you to JP. This is truly the fix for the dreaded AE error code on any of these LG units!
Starts at around 3:45. Thank you for making the video, I will try this fix.
So, so, so happy to find your video!! Thank you!
Looks like I’ve got the same problem. I had it pretty much narrowed down to this being the issue, but you made it understandable. 👍
Man, thank you for all the time, frustration and money you just saved me.
You are the best! I literally unscrewed 100 screws because i thought this sensor was near the pump, before watching your video!
Thank you so much! You did good Sir! Very very good straight to the point detailed DIY video. Fixed my problem in a snap.
This was Very informative. I am sure that it saved us the cost of a repair visit or a new dishwasher. I can't say for sure but the little valve in the side tank may have been the problem, or a small high-pressure leak (that was tightened), at the water connection from the house to the dishwasher. One fix that you may want to comment on before doing...it is to clean the inside of this valve using vinegar and baking soda. It fizzes and creates a little pressure that cleans most anything it comes in contact with. I did do this, also because the water was off while cleaning the washer. Anyway... no AE code and we have clean dishes. Thanks for the insight! I wish more people would have the same caring nature for others as you have expressed in your you-tube post.
You’re the second one that has mentioned using vinegar and baking soda to help clean it out. Excellent point with how it helps clean the gunk!
Thanks for the great video. It fixed my problem. Here is a tip for cleaning the mass. It is mostly biofilm bacteria, If you soak it in 90% isopropyl alcohol then expose it to a very bright or ultraviolet light source it will deteriorate a lot faster.
Thanks for the tip, worked like a charm! I have had so many problems with my lg appliances, but thanks to youtubers like you, they are still working, Thanks again.
Thanks so much for taking the time to make this video. I have the exact same model DW and the same problem, thank you for sharing it saved me big bucks.
You rock! I had this exact issue. This helped a lot. Merry Christmas to you and your family. Best wishes!
Wow!! Thanks a ton. Great explanation clear and consice, I had the same problem, and now the dishwasher works great.
THANK YOU SO MUCH! Not the way I wanted to spend my evening but you saved me a bunch!!
Thank you so much. You saved us $$$$. You are the only one who described it correctly and had a solution.
Brother. My man!!! It was the airgap much appreciated you saved me a tonnn of time and money. Thanks you🙏🙏🙏
Had the AE error on my LG dishwasher. Found this video to be very helpful diagnosing the problem. Took my time and used CLR to clean out the float chamber and very hot water. After reinstalling and pouring in hot water into the basin of the dishwasher I turned the power back on, and watched the water moving through the plastic valves. I then sponged out all the water in the basin and noticed the internal purge pump stopped cycling on and off, however the AE code was still present. Powered off the machine holding the power button and powered it back on, and the error was finally clear.
Thank you!! This fixed my machine. Very much appreciate you taking time to make the video!
Even if this video may not help me fix my (almost exact) problem your explanation and detail is A++!
Thank you for this video. It's unknown yet if this will be the problem my in laws are having but it is certainly something I can investigate now. Both my parents and my in laws both bought these LG dishwashers and they are currently both suffering from(different) error codes after working without issue for (only) about 2 months.
Thank you for this video. I had the exact problem on a similar model LG dishwasher and following your video fixed my issue.
thank you so much my dude! you and your cats just solved an issue and made me look like a hero!
Thank you I just fixed my LG dishwasher with exactly the same problem!!!
Took me a while to get the dirt/fat out of that little valve section
Thank you for this video!!! I searched several hours for causes and solutions for my LG dishwasher and BINGO this was my problem…
Glad that it helped out!
My man! Fixed it following your steps. Thank you 😊
You’re a fantastic instructor!!!
06/21/21 Due to a under drain plumbing issue, my sink backed up and I had this AE error code again. I cleaned out a piece of food in the air gap assembly like before but the error remained. I could feel water in the bottom pan, so I tilted the washer to severely to the side to drain the water from the pan and it cleared the code immediately. Thanks again JP!!!
That’s a great tip!
Thank you SO much!!! This is exactly what was wrong with mine. Did exactly what you did! Fixed!!!!!
Worked for my LG. All I was missing was the cat. Thanks!
Thank you so much for posting thiss!!I was about to give up until I came across your video! Fixed my dishwasher finally 😊
Thanks from Saudi Arabia, I've implemented your instructions and the dishwasher works fine again 👌
Thanks awesome!
Thanks to you, sir, my new LG, which has not seen its first set of dirty dishes, yet, has worked. For some reason, the machine would not clear the water where the sensor is. I’m giving it its first test, now. It’s working, and the error code has been cleared.
Thank you so much
Perfect! This saved me hours of troubleshooting! Thank you so much for making this video!
This video helped me fix my AE error. My issue was different though. It wasn't clogged, there was water in a section of the part where there shouldn't have been any water. So grateful to have found this video because it ultimately gave me the solution. $42 delivered for the part and no service call! Thank you!
Glad to see the information was able to help out in more ways than one. Excellent job on fixing it yourself as well!
Thanks for the great information. I am really hoping this helps with my constant OE errors when I go to fix this on Saturday.
You’re the man!!!!!!🎉Plus playing my most favorite Christmas 🎵 song. It don’t get no better👍🏾.
🙏🏾 thank you
Have a Merry Christmas 🎁🎄
Not All Heroes Wear Capes, you sir are a hero! Thank you so much for this awesome video.
Lovely video! I had the same issue woke up with ae error. For now I just cleaned up the water at the bottom tray. If this occurs again will work the remediation you are explaining! Thanks for the video, this helps a lot.
wonderful fix. About 8 months ago I actually had no functioning buttons. I had to tear the dishwasher apart and found at some point there was a small leak that got on the end of one of the electrical plugs and it took out a connector and my main board. I replaced them both and unit has been working great since. Now tonight I'm getting random OE codes and the unit does not seem to want to drain as good as it should. Thought maybe pump was going on but its clear the pump is still making noise at the beginning of the cycle. I will be checking this out next
You are a life saver. We did this and wow issue solved and hundreds saved.
You did a great job explaining this! Thank you!
Your feline assistant was very helpful 😻
Thanks to both 💐🐟
Great Video! I have a model LDT7808SS with an E1 code - and it was this exact issue! Thank you!
You the best brother! God bless you and your family
Thank you man you really helped out appreciate the work of the video! London🇨🇦
Fixed! This is exactly what mine did!
Thanks brotha!
Very helpful video . I had a suspicious hint but I didn’t want to take out the dishwasher. Now it makes more sense and I know what to do . Just going to have wife worry about it first .
Thank you for posting this video. I don't have that exact model but the inside is the same so I followed your instructions and mine was full of guess what......collard greens from Thanksgiving dishes. I have told my wife and daughters to rinse dishes off before loading the dishwasher time and time again and they don't believe me but this is my proof!!!! Guess who doesn't have to do dishes for a while? This guy!!! Thanks Bud
Thank you so much! You saved me so much money! We couldn’t run it for a week because of the AE code🤦♂️. Thank you for taking the time and making a great video! I got it working because of you!
You are awesome. I found water in mine after giving up on LG on a 15 month old dishwasher. No warranty to cover this nor good support.
I needed to replace the drain hose your video helped me take apart the assembly then replace the hose and the dishwasher still works! Thank you very much!
Aggravating but I saved a service call $100 estimate
Part was $24.99
How did you determine that? The area that he showed was clogged on mine. I cleaned it and witnessed it operating correctly when rinsing but I'm still throwing the AE code.
I have to do this as well. I guess I cracked the drain hose because the larger hose was filled with water and leaking under my sick. Does the drain hose going to sick drain pop right off? Looks like there’s a little black o-ring
The hose was kinked when I removed the dishwasher from under the counter, I had no grease in the trap, replaced the hose reinstalled and it cleans better than it ever has!
The hose has a ridge in it plus the o ring, once it’s in the ridge the o ring is installed but the assembly on the side has to be removed so you can see and access the removal of hoses and connections, hope this helps everyone
this is why i love youtube. you rock, dude. fixed my issue!
Thank you so much! I’m cleaning out the valve gunk and saving money! 🥰🇺🇸✊
You fixed my dishwasher! Thank you! I own the exact same dishwasher.
Although it didn't clear my AE code, it was kind of fun cleaning this thing out. I was like the Neti Pot of appliances. So much grossness in there. Thanks for your clear instructions!
ETA: it did work! However, I had to get the water out of the pan underneath to make the code clear. I accomplished this by tipping the machine forward and mopping up the spilled water with towels. Thanks again!
Saved me from buying a new dishwasher! Great video.
This worked for us! Thank you for this video, it's the only thing that helped.
