    The rotating arm (that sprays water) under the top drinking glass rack keeps falling off. I reattach it by snapping back in place but it eventually falls off again. I don't know the specific part name to order a new one
    For model number LDF7774ST
    Hi Ken, thank you for your question. That part would be called your nozzle, part number: PS3527665. You may also need to replace the guide it clips into as well: PS12075961. Good luck with your repair.

    The dishwasher continues to cycle until the door is open or the breaker is turned off. Do you know what part I would order to fix this problem
    For model number LDF7774ST
    Hello and thank you for writing. Your dishwasher runs on a cycle of cleaning and drying. When the washer will not switch over from one cycle to the next, it may run continuously until you either unplug the unit or open the door of the unit. A dishwasher that continues to cycle may have a bad heating element PS7788065 or control panel PS10066436. We hope this helps. Please contact us anytime if you require further assistance.

    When i push the power button, are all the buttons' backlights supposed to come on? On my dishwasher they do not and it's very hard to see which button is which without shinning a flashlight on each one. Only the outline square lights up when a button is pushed.
    For model number LDF7774ST
    Hello Kenneth, thank you for your question. The lights should only come on when a button is pushed. They do not all light up.

      Keep searches simple. Use keywords, e.g. "leaking", "pump", "broken" or "fit".
      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".

      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.

      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.
