Awesome video. Very helpful. I got my pump replaced today. NOTE: DO NOT TEST WITHOUT MIDDLE RACK INSTALLED or you'll get a nice leak from the front and chase that down for like 5 hours...

[@hobbycow5346]

This was Extremely helpful!!!! Thank you for making this video! Our pump makes that exact whine. This is stuff the manual doesn’t tell you. They just want you to call their technicians and charge you $$$$.

[@benjaminfeldman9926]

My exact issue as well. This video was extremely helpful. Our LG dishwasher had all the symptoms mentioned in the video (the washer didn't complete the cycle, there were dirty dishes with dirty water in the dishwasher filter region, the detergent wouldn't empty from the detergent bin, and the high pitched whine was heard with Drain Error on the display). I called LG service and they indicated that it would cost $90 to have a local repair person come by and make an assessment. Of course there would have been additional cost for labor and the $50 part would have likely been marked up by the service company by 100%. I was able to fix the dishwasher, prevent landfill waste and I probably saved between 2-300$ in the process. Many thanks. The dishwasher is working perfectly now. The spare part was ordered from e-bay for $52 including the shipping. I also noted that checking the resistance of the drain pump with a multitester was useful. The bad drain pump measured 9-11ohms and the replacement was 2 ohms further giving indication that the repair mentioned in this video would solve the problem. I didn't have to replace the black rubber one way reflux preventing valve in the sump housing adjacent to the drain pump. That valve could only be seen on my unit after the faulty drain pump was removed and it was obvious that the rubber valve was positioned correctly and did not need to be replaced. Save yourself the money and prevent landfill waste by fixing this problem yourself!! This is a low to mild complexity fix. Thanks for this great video. I didn't have to go out and buy a new dishwasher!

[@soonsengutube]

Thank you for the video even it is likes 4yrs already.. It helps me in my diagnosis and pump replacement as shown in your other videos.

[@chicagohandyman]

You’re welcome!!

[@richardbauer5739]

This video was spot on for my problem. My Symptom was that pump would not run continuously when in drain mode. One or two second bursts. New pump runs continuously in drain mode.

[@clintevashkevich]

Thanks for making this! Helped us diagnose our dishwasher and realize the pump was gone.

[@chicagohandyman]

No problem. I’m also learning that a clogged drain hose could also result in the same problem. Something to keep in mind.

[@cartercordingley6062]

Thanks. Was able to fix my dishwasher with help from this video and one other one that pointed me to it being a drain pump issue

[@robinkuruda5249]

My exact issue !!!, Thanks for posting !!!

Thanks for this. Helped me diagnose the problem with my DW and have the confidence to fix it myself.

Good luck! Check out my 2 other videos that shows you 2 methods for the repair.

Thanks for watching!

[@pelizzari2010]

Thanks for this good video. Can you show how to take off the bottom part that cover the pump in normal LG .

[@StefaanVanDamme]

I had the OE error, drain program did not work; ended up blowing in the hose a couple times, did the trick :)

[@yannickmartin4796]

Great video. Explain everything quickly. Not my exact model but close enought

[@chicagohandyman]

Glad it helped

[@charlesmayer7097]

Thanks for this video.! I need to recap on how to reinstall a drain pump. This is the second time I've had to replace it. I'll never buy an LG product again.

[@chicagohandyman]

I had to replace my pump again and I also watch my own video again to see how to do it!!

[@troypierce1924]

Thank you so much this was very good information.

[@chicagohandyman]

Glad it helped. Good luck with your repair.

[@miked5106]

I have a kdp6787bd, high pitched whine at start up sounds like pump, but no discharge to the disposal. When I cancel cycle it drains fairly quietly. Is it the grinder bearing in the pump making the noise? Not throw a code but this thing is noisey.

[@TheMrKordunas]

Tried pushing those 2 buttons, but it looks like delicate button not responding. Any idea?

[@sulwalki]

Thanks for the helpful video. Pulled the pump and it registered the right ohms. I was checking the impeller, and I was able to pull it away from the housing just a tad (sounded like removing a suction cup). Reinstalled it and it now it works fine...no more residual water. Hope this may help someone.

[@chicagohandyman]

Maybe your hose was clogged.

[@Erich1]

How did you pull the impeller away? I tried gently prying from both sides with 2 screwdrivers at the same time but I was scared the impeller might snap off. I suspect there might be some debris trapped underneath. I measure 4.2 ohms so not sure if my pump can somehow be saved?

[@sulwalki]

@@Erich1 It didn't require much force. It popped out a bit by gently pulling it straight out. I wouldn't use any tools doing this. I can't say this a fix for everyone; it just worked in my case. BTW my washer is still emptying flawlessly.

[@sulwalki]

@@chicagohandyman Hose was clear. It was the impeller.

[@Erich1]

@@sulwalki I tried prying really hard on the impeller and it won’t budge. It rotates with just a bit of resistance so I might leave it alone. Not sure how you pulled your impeller out.

[@skozzy1968]

My LG Dishwasher has buttons on the outside of the door, and has some different descriptions/labels on the buttons, 'Dual Intensity - Auto - Eco - Quick&Dry - Quick', model is LD-1482W4, which button combo is needed to turn the drain pump on. Normal use I hear it start, water comes out at the sink, yet I still get the error, it does how ever only run for short bursts

[@chicagohandyman]

Look for a combo that says “Cancel”

[@JamesTaylor-lf5yz]

I have the same issue. Did you figure out a combination?

[@juanblanco1371]

On mine it's Delicate and Dual Control

[@inachu]

But how to remove the cap inside the dishwasher?!??!?! It moves up and down does it just pop off?

[@amir-alimoosavizadeh9184]

Did you measure the voltage going to the pump during pumping. Mine does the same as yours and when I force it to drain, the pump works for 3 seconds then stops for 5 seconds and then starts again and keep doing the pulsing drain. I checked the resistance it reads 4.6 ohm I also checked the voltage going to pump it reads pulsing from zero to maximum 0.7 volts!

[@josephjames6369]

Is it supposed to pulse? I'm getting the DE code as well and if I force it to drain, it pulses like yours..

[@larrynelson1776]

@@josephjames6369 I had the same problem, surging water flow from the pump but not completely draining. OE error before the soap drop and water left in the bottom. Ordered a new pump and had it in in about 20 minutes, only tools needed were a philips screwdriver to remove the kick plate and a pair of pliers for the hose clamp. Solved the problem and I now get a steady, strong stream out of the drain tube. Given the number of google hits on LG OE error I'm suspecting this is a very common problem.

[@60retired]

Where did you get the info that 3-4 ohms meant the pump was good and over 5 ohm is a bad pump? My new replacement is reading 5 ohms and the bad pump is 4.3 ohms. Verified these readings 3 times with two different high end digital multimeters.

[@chicagohandyman]

It was probably in a PDF from LG somewhere or possibly the wiring diagram on the inside of the toe kick cover.

[@mecan277080]

My kitchen sink got clogged up and the dishwasher will not shut off. I turned off the breaker for a few minutes but when the power was turned back on, the dishwasher was still running. Any idea how to shut it off?

[@chicagohandyman]

Never had that happen to me.

[@tetyoonlee4373]

With my LG I get something similar but it has an E1 error. From what I can tell, E1 means water has leaked out and the dishwasher has detected the water leak. The dishwasher then turns the pump on continually to try and empty the water. Even if you turn off power to the dishwasher, it will come back if it still senses water where it shouldn't be. You need drain it then let the water it's sensing dry out. Only then will E1 go away when you cycle power to the dishwasher. (Well technically provided water isn't still leaking you don't need to drain it but it's probably best.) As I mentioned in another reply, you can get E1 error with a draining problem, especially if you keep trying despite an OE error without properly emptying the dishwasher.

[@LocalAutosOnline]

I bought a brand new drain pump and I got a 5.4 ohms.. just an fyi

[@rockydelaretojr8463]

Powers on but I have 3 dashes on the display and the dishwasher won’t run.

[@ironbutterflybye1]

I have an LG LDF7551ST. Shows code E1. Power light stays on and pump runs continuous. i turn off with breaker pour water in and restart water will pump out but unit keeps running. I checked drain hose blew air back to unit no clogs. Could not find any leaks....????

[@giantsmanning101]

Figure it out? Same issue.

[@tetyoonlee4373]

As far as I can tell, E1 means water has leaked out and been sensed by the dishwasher. It then turns the pump on continually to try and empty the water. Even if you turn off power to the dishwasher, it will come back if it still senses water where it shouldn't be. You need drain it then let the water it's sensing dry out. Only then will E1 go away when you cycle power to the dishwasher. As for why E1 happens, it may be because the dishwasher got overfull because it wasn't draining properly, especially if you tried to run it a few times despite DE/OE. Or it may be there is a leak in a hose or something. If it's just an overflow from not draining properly, then this video could still apply.

[@markostertag1101]

@@tetyoonlee4373thanks for this. I just worked on my dishwasher trying to fix the lack of draining issue and now I’m getting a 1E code. However, I’m theorizing that the code may be coming through because in the process my dishwasher got water everywhere in it lol. That would include areas it’s not supposed to be. And there are no leaks underneath currently so hopefully tomorrow the code won’t come back.

[@harryeichelberger4799]

ldf7774st is my model... Pump works fine, even replaced it, still OE.

[@chicagohandyman]

Sounds like you have a clog in your drain line.

[@chicagohandyman]

There’s a comment I posted here somewhere that explains how to clear the clog.

[@harryeichelberger4799]

​@@chicagohandyman Thank you for commenting. I replaced the drain line, replaced the pump (the new one seems to be weaker than the original), I just replaced the sump assembly tonight, I've blown the drain out multiple times... Still OE.

[@Xi-op7gg]

Have you checked the air gap?

[@Cutecat4454]

I put in a new one it still doesn’t drain and the new one makes that high pitch whine. Any suggestions?

[@chicagohandyman]

Disconnect the drain hose under your sink. Use a wet/dry vac to suck on the end of the drain hose. At the same time, force a drain cycle on the dishwasher.

[@chicagohandyman]

You probably have a clog in your hose.

[@yamipizza8357]

My new pump is showing 4.8 ohms. It is spinning but doesn't sound like it is moving water. Any ideas?

[@chicagohandyman]

Sounds like you have a clog in your drain line. I would take off the end that goes into your sink drain. Take a wet vac and vacuum on the end of the hose while running a drain cycle. Hopefully that will get your clog out.

[@elwerfally]

What's the difference between DE error and OE error

[@chicagohandyman]

The actual error is DE. With the limitations of the 7 segment display, the D is confused as an O. There is no OE. Also, DE stands for drain error.

[@jakepetty5578]

So that intermittent pumping mine does says it’s going bad

[@chicagohandyman]

Yes, inevitably. It would be a good idea to get the part in advance so you have it when the pump fails. I’d keep using the dw as-is until the bottom of the dw is no longer dry after running it.

[@slackerzsincity8822]

What If I never used it and its giving me a error, my kid pressed the power button and it was the first time I ever used it, we only used for storage

[@chicagohandyman]

What error message are you getting? You might be getting a DE if your drain line is clogged from sitting unused for a long time.

Same here dishwasher not draining. After replacement it worked fine only for one cycle. In the second cycle the DE error showed up. What to do?

[@emilyvoss4192]

So what happens when It is still showing DE and the pump has been replaced?

[@chicagohandyman]

Does the new drain pump sound like it’s running and you still get the DE? I would disconnect the drain hose and connect it to a wet/dry vac. Turn the vac on, and turn on the Drain feature on the dishwasher.

[@chicagohandyman]

But first, I would fill the bottom of the dishwasher with about 4 cups of water.

[@emilyvoss4192]

@@chicagohandyman correct it runs and and water moves/drains but it DE in the middle of a cycle. I have tired drawing water from the end of the drain tube and it works but for not every cycle. My thinking is the check valve may be stuck.

Please share a better place to buy them from. Thanks!

[@WeWander2]

problem solved Amazon ABT72989206 $173.67 Phillips screwdriver and pliers required. Would say I'm unhappy with LG service, but that would imply that they responded and have a service department. They want you to throw it away and buy a new one. I think it's sad the one part LG brags about failed in 2 years regardless if they think it's going to make it 10.
