UPDF9904ST LG Dishwasher - Instructions

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 water, 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".

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 disconnected the electrical wiring (breaker was shut off). 2. Shut the water supply off and removed water line at the dishwasher. 3. Disconnected the drain at the sink. 4. 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.

The inside gasket deteriorates over time - However replacement is easy. the main thing you have to remember is after you remove the old gasket, install the new one starting at the middle top of the tub and work your way down both sides. Also, don't push the gasket all the way in...only enough to hold in place. When you close the door the gasket will form a better seal around the door.

First do not watch the videos . They had you taking the insides all apart
when all you had to do is pull the unit out , twist the motor out and put the new one back in. Take nothing apart inside the dishwasher.

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!

Unscrew all screws on the inside of the dishwasher door. Carefully separate the front panel from the inside panel. Lift out the latch assembly, remove connectors from both sides using needle nose pliers. Reconnect to new assembly and situate back into place. Close front and inside panel, replace all screws, making sure the short and long screws go back to where they came from. Quick easy project to eliminate 2 trips from a repairman, 1 for the diagnosis and 1 to do the work!

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.

Had to call have an installer attach a metal strip across granite counter top and they did not have the top mount brackets so I had to order them and finish the install. The dishwasher was installed on the side mounts and they missed the cabinets

I am 77 years old and got it all on but the corners did not want to go in so I had to call my grandson and he got them in. It still leaked on the bottom left side. It is getting old (11 yrs) so I decided to get a new one. It is actually pretty simple to install, but it does take a little strength.

Followed the video provided by your company, done like 1,2,3

same as in the video , but the double red wire is on the wrong terminal you have to break the plastic housing on the dishwasher and put it on the first one next to the white wire .if you hook it up the way it is the dishwasher wont work and when you open the door the dishwasher turns on . watch the video real close when it gets to the wire connections you see the double red wire goes over one pin to the one next to the white wire . works fine after that.

I went to Youtube to get an idea of how to approach the repair. First turn off the electric power to the dishwasher. Then turn off the water valve that's connected to the dishwasher. Then disconnect both electrical and water lines connected to the dishwasher. Then remove the dishwasher from under the counter. Then place the dishwaher upside down. Remove the old hose,and install the new hose. Place the dishwasher right side up, and reconnect the water line, and electric line. Place the dishwasher back in place, and you're done.

Saw a YouTube video that explained the problem was the pump. Removed dishwasher from under the counter, flipped it on its side, and unplugged the unit. Removed bottom cover and the pump is right there. Used pliers to lose and move 3 hose clamps. Unplugged 3 wires and unscrewed the ground. Unhooked rubber hold downs and removed. Installed new pump. Parts Select pricing was best I found and shipping was fast. Nice to have a quiet house again when running the dishwasher. Cost in total was less than $100.
