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.

Very easy repair. First remove all the screws from the inside of the door, making sure you support the outside part of the door with a pot under it on the floor. Pull the locker part out, remove wire connection with needlenose pliers, and install replacement part. Put door back together, and you're done.

The dishwasher door would fall open when opening if it wasn't lowered slowly.

  • Customer: Allen from N LITTLE ROCK, AR
  • Difficulty: A Bit Difficult
  • Time to Complete: 15 - 30 mins
  • Tools Required: Nutdriver, Screw drivers, Wrench (Adjustable)

I disconnected the power cord and the drain hose, with a nut driver, under the sink. I removed the bottom plate that covers the water connection under the dishwasher. With the water turned off I used an adjustable wrench to disconnect the water line. I open the door and disconnected the brackets under the counter top, with a phillips screwdriver, that hold the dishwasher in place. I pulled the dish washer out of its enclosure far enough to fully access the spring loaded mechanism to replace the "connector assembly". Then I put it all back where it belonged.. Go slowly and have patience.

Unit would not start up

  • Difficulty: Easy

Conclusion was that either the control panel or the noise filter (an electrical fuse apparatus)was bad. Disconnected the water line, turned off power, and pulled unit out from cabinets. Determined that voltage was going into the noise filter (white harness) but almost no voltage coming out (red harness). Ordered noise filter. Hardest part was removing old noise filter from dishwasher frame without removing the whole unit from cabinet and turning upside down.One screw holds the part in the frame. With power off, I used a very small ratchet with phillips screw driver. Pried unit out with screw driver on side to the panel front. It has a retaining tab there.Installation was the reverse. Instead of putting screw back the way it was originally installed, I screwed it in from the outside of the frame. Much easier and just as solid. Tested unit with power on. Hooked up water line. Works great. Note: LG dishwahers have a high repair rate and that this part has a high failure rate. This LG unit was two years old. Never had to fix my 15 year old Sears dishwasher. It still works to this day. (I gave it to my daughter.)

First, PartSelect is great!; fast,& accurate. 1. Inside the dishwasher: remove trays. Remove (A050) lower water sprayer from bottom by pulling up. Remove (F191) top sprayer assembly by pulling away from clip holders. Remove (M110) by removing the holding screws. This part cover the whole sump and has kind-of an open screen circling the unit. Now you will see the white plastic impeller (M120) which is attached the the motor with one Phillips head screw. WARNING. The Phillips head screw (holding the impeller in place) is a REVERSE THREADED SCREW. Turn the screw CLOCKWISE to remove it. Then remove the impeller from the motor shaft. Underneath and outside the washer: Remove the bottom plate. Finally remove the motor by unscrewing the four holding screws and electrical wiring.

These were a simple snap on item. It took longer to carry the parts from the porch that to install. Recently purchased house. Rollers were missing due to overload?? Removed the remaining roller pieces. Cleaned and straightened the axle shafts, spray lubed the tray and snapped the new pieces in place.

Old door seal appeared ok, no rips and seated evenly all around. Pulled that seal out and replaced with new. Seated new door seal after wetting inserted lip. Tested...leak greatly reduced, but still dripping. Removed seal, placed a rubber rope (same rope used for screening) within the tub recess, then reseated new seal. leak ceased. Also replaced the reservoirs on the left side of the cabinet (guide assembly). Old reservoir had debris within so decided to replace. Used regular pliers for the 3 hose spring clamps underneath, and a pair of large neede nose pliers for the fill flange (regular thread).

parts were not exact match with original, even though ordered from schematic. had to bend the replacement part slightly so it would fit into holder pieces. this took about 10 minutes as I was trying to be careful not to break/cut the coating (which would then lead to rust again). Once the piece was bent, just snapped the rack into place.

Service tech diagnosed problem to the main PCB inside the door; his parts supplier indicated that the part was no longer available. We checked with PartSelect and they indicated that it was available as a special order item. We ordered it and shortly thereafter, the service tech contacted us with a part number for a substitute. Again, PartSelect had it available and this one in stock. Canceled the special order item and ordered the substitute. PartSelect followed through with email notifications. Part arrived within two days but the wrong model had been sent inadvertently. Joelle with PartSelect straightened it out and we had the correct one in two days. We installed it in about 30 minutes using an electric screw driver. Very easy! It helps to take a picture of the old part before taking it out to make sure the new one gets installed the same way and the wires tucked under as before. Joelle did a fantastic job verifying that the correct part would be shipped and followed up with the part return and all charges getting credited. Dealing with PartSelect was an excellent experience; will keep them in favorites list for all do-it-yourself appliance repairs.
