Sample Model Number Tags
Model numbers can be made up of numbers (1005400, for example) or a combination of letters and numbers (LAT1000AAE). The model number will most likely appear on either a paper sticker or a metal plate. Your appliance's model number tag may look similar to the sample model number tags shown here (model number highlighted in yellow):
This drain pump assembly is a genuine OEM replacement part for your dishwasher. In order to complete this repair you will need a Phillips screwdriver, pliers, and a socket. You will need to pull the dishwasher out from the cabinet and lay it on its back in order to access through the bottom and replace the drain pump.
How Buying OEM Parts Can Save You Time and Money
Why buy the real thing?
OEM stands for Original Equipment Manufacturer. Simply put, this means that the company who made your appliance is also supplying the replacement part for it.

Play the percentages: it worked for me.
As a low skill self-repairing homeowner I found using the PartSelect website in conjunction with my dishwasher owner manual led to complete success of the repair.
It was easy. Using the symptom (dishwasher won't empty) got me to the general area in need of repair according to my dishwasher owner manual. Using that information I went to the PartSelect dishwasher repair section using the same symptom as my guide. It said that it was an 81% probability that the problem was the part. I ordered a new one. It worked and I couldn't have been more proud of myself or happy to use PartSelect in the future.

dishwasher not draining
turned off circuit breaker. Removed bottom panel which allowed access to drain pump. Disconnected electrical plug. Clamped hose clips and removed hoses. Removed old drain pump assembly. Installed new assembly by reversing process. Access was a bit tight but managed to do it without pulling the whole dishwasher out of the cupboard.

Water in dishwasher at end of cycle. Error e1 / d1
I actually didn't remove whole drain pump assembly. Just removed the old pump motor by rotating. Lots of water drains out so be ready with an old towel. Then installed the new drain motor and tossed the new housing. No more water at the end of cycle!

Dishwasher wouldn’t completely drain
Shut off electrical breaker, Removed bottom cover plate by removing 2 Phillips head screws. I was able to remove the pump without pulling the dishwasher out by removing wiring connection, hose clamps with a pair of pliers, and removed the 2 rubber hangers However I couldn’t reinstall the pump without pulling the dishwasher out. 1.I disco

Removed the 2 retaining screws 1 on each side that secures the dishwasher in place. 4. Removed the upper and lower racks, Used a shop vac and sucked the water out of the bottom of the dishwasher. 5. Pulled the dishwasher out making sure the drain line came with it. 6. Laid The dishwasher over on the back side to the floor. 7. Reinstalled pump with new hose clamps and hoses that came with the pump. ( it probably would have been easier to remove the pump with the dishwasher pulled out) reinstall the wire connection to the pump (snap in connection), connected the 2 new rubber hangers to pump and connected to the dishwasher . 8. Slide the dishwasher back in place and reconnect water line be sure and use some Teflon tape, reconnect electrical wiring, reconnect drain line, secure dishwasher with screws. Turn water on and check for leaks, turn electrical power back on. I ran the dishwasher to make sure it worked and make sure there weren’t any leaks before I installed the bottom cover plate. I had an appliance service person say that they wouldn’t work on an LG because they were hard to work on and very difficult to get parts. My experience was just the opposite thanks to partselect. The Dishwasher works like brand new.

Water not draining, causing "0E" number to appear and initiatate dishwasher shutdown.
According to your site, the part(s), to consider, to resolve the problem were: 1.Motor Assembly DC Pump, OR 2.Drain Pump. I simply selected the drain pump because it was cheaper and because it was making a clicking noise. (The only significant noise that this dishwasher was making) To be safe, I unplugged the unit and turned off the w
... Read moreater, under the sink. I removed the kick plate and I unscrewed the anchor clips from under the counter and carefully pulled the unit out. I then opened the dishwasher and removed the lower rack. To minimize water clean-up, I took a rag and soaked up the standing water in the bottom until it was nearly dry. I then tipped the dishwasher on it's left side, knowing where the location of the drain pump (front, right), would be in an easier location for me to work. I first unplugged the pumps wiring. Then, with pliers, I was able to disconnect the clips on the short, rubber hoses that hold the pump in alignment.(Use caution: If reusing the same rubber hose(s) on the new pump, it will be easier if you put them on in the same direction as they were take off) Then I removed the rubber supports off their hooks, that allow the pump to hang from the bottom of the dishwasher. Once the rubber hoses are re-connected on the new pump and placed on to it's former proper alignment, you can re-attach the rubber supports to their hooks. And last, but not least, remember to plug the new pump's wires back in place. Carefully stand up dishwasher and push it slowly back into place. I plugged in the unit and turned on the water. Before I screwed the unit back to the counter and kick plate back on the front, I ran a load and watched for leaks beneath the new pumps area. No leaks. "Easy, Peasy".

Dishwasher not draining. When i manually run the drain cycle the drain pump pumps water into disposal for a few seconds and shuts off and then I hear a whining noise for a few seconds. Pump cuts back on and runs a few seconds and shuts off again and I hear the whining noise again and this continues till it’s empty. Is this a common issue on this model and what are some common causes? Thank you for any input you may have.
For model number LDF7551ST
Hello Jason, thank you for inquiring. For this symptom you will want to replace either the Drain Pump part PS11706890 or the Pump Motor Assembly part PS11710287. We hope this helps.

Machine is not draining, giving an 0e error code. I've checked the hoses, no kinks or breakage. It's not making any unusual noises, just fills up with water and then stops and gives the error code. Could it be the drain pump? Thanks!
For model number LDF7774BB
Hi Taryn, thank you for your question. The 0e error code means that either your have a clogged drain hose or a clogged/faulty drain pump. If your hoses are not clogged then you will have to replace your drain pump. Good luck with your repair.

Drain pump runs at beginning of start cycle but OE error code at end of full wash cycle. Selecting half load and pump out completes and no error code. After getting error code I turned off machine and came back next morning and ran maintenence pump out just fine. I replaced the drain pump but still have the same issue. No hose kinks or filter blockage noted.
My questions 1 Could this be a logic board problem? 2. Could the pump motor be overheating and shutting down until it cools, than works fine? 3. Maybe the replacement pump was also defect?
For model number LDF7774WW
Hi Steve,
Thank you for your question. Sometimes the OE error code may be the result if a glitch in the electronic control board. This can be fixed by turning the power off to the dishwasher for 5 minutes. If the error code reappears after you have restored power to the dishwasher and you have already checked the pump, the hoses and the filters, then the electronic control board may be defective and you will need to inspect it. If you have any questions, please let us know. We are open 7 days a week. We look forward to hearing from you!

Dw is just over 2 years old with very very minimal use. Would missing a fin (there were 4 but looks like one is missing) on this pump unit stop the pump from engaging to drain? Is there anything else that would prevent the drain pump from engaging? Or being able to test the pump? Dont want to have to replace parts that are not the problem, of not draining. This particular dw has a disposal built in, there is no filter in the bottom of the rack like the other dw's.
For model number model # LDS5040ST, serial # 509KWRE1S270
Hello Bambi, Thank you for the question. The missing fin should not effect the draining but if it broke off and got lodges or sucked into the pump, it could have damaged the pump. I suggest removing the pump and cleaning it out to see if there is anything causing a blockage. Hope this helps!

Dishwasher makes high pitched whistle noise when filling before washing and when rinsing. Washing, draining, and drying are all fine and quiet. What part do you think i may need to replace?Thank you,

For model number LDF7774BB
Hi Angela, thank you for your question. You might want to take a look at your water inlet valve and inlet parts to see if there is something there causing this noise. I hope that helps. Good luck with your repair.

The drain pump will run for a few seconds and pump a little water out then stop. It will pause for a few and start the cycle over until it times out. Once the water is out, it will run continuously until it times out. So I know the pump works, just not when water is present. I also took a towel and applied a little pressure to the spinning pump blades and I could hear it go faster due to the resistance. Can you tell me what part I need? Thanks
For model number LG ldf7551st

The dishwasher has a slow leak or drip underneath the unit in the pump area. What is the likely cause?
For model number LDT7797ST
Hi Dave, thank you for the question. We would suggest checking the drain hose for any damage first. If it is fine, the issue could be with the drain pump, part number PS12076726. You may need to replace it to fix the issue. We hope this solves your problem!
