My dishwasher doesn’t go through the complete cycle. I get a DE or OE code. The soap doesn’t open. I can press normal and delicate at the same time for 3 seconds and then it will completely drain out.
For model number LDF7551ST
PartSelect logo
Hello Rick, thank you for reaching out. According to our research, the OE error code in your dishwasher indicates that the unit has detected a drain issue. It may be due to clogging of food particles or debris in the filter or the drain hose. It is suggested to make sure the drain hose and the filter are not blocked. If the issue remains, the drain pump, part number PS11706890, might be faulty. We hope this information helps!

Assuming only one door spring needed for this model. I replaced the existing spring without noticeable improvement (used new spring part L-G-4970ED4004G and hooked it up as per original installation). What am I missing...? Can you help ?
For model number LDF7551ST

Hello Jan, thank you for the great question. According to our research, there are two-door springs. One on each side of the door. We recommend you replace the other door spring to fix the issue. The part number for both springs is PS3524564. We hope this information helps!

Broken door spring allows the door to overextend to the floor if not propped.
Simple, removed screws securing machine in the cabinet, then pull the unit out of the cabinet space about 10 inches. Springs are accessible within this extension. You need strong hands to extend the springs and attach them. Once attached, push machine back in place and re-install the anchor screws. In my situation, only one spring was broken, so the attached side revealed the correct slot to place the hook on the top position, the bottom position has a plastic lead for the spring, and that lead is attached to a rope to the door hinge. Note: Replace BOTH springs, even if only one is broken.

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 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".

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 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.
