remove lower rack. place in trash. place replacement rack into dishwasher

E. Z. hardest part (which isn't hard) was moving the appliance to reach the back, then putting the appliance back into place. the actual repair (swapping out valve) took less time than that to do.

First unplug the machine. Turn the water off to the hoses. Remove the hoses from the machine to make it easier. Remove the screws from the back of the top cover. Pry the front sides with a screwdriver and lift. Standing behind the machine on the left side you’ll see the three solenoids or inlet assembly. Remove the two screws so as to take the inlet assembly out. There are hoses attached to the assembly.

Disconnected the electricity, the drain hose, and the water supply from the dishwasher. Loosened the two screws from the countertop and pulled out the dishwasher. Turned it on to it's side. Saw the damaged inlet sump. Had to remove the Pump connector to get to the inlet sump. Checked it also and discovered that it was starting to develop a small crack from the inside. I decided to replace it as well. The job involves removing the hose clamps and removing the spray mechanizm from the interior of the dishwasher to spin out the inlet sump. Not a difficult job.

Open dishwasher and remove the bottom spray wheel, filter, and unscrew the mounting bracket to release the pump connector below the bottom of the unit. Remove mounting screws at top front of dishwasher and carefully slide the unit out; you may have to pry side panels inward with a flat screwdriver in order to get the dishwasher past any cabinetry. Be careful not to pull the dishwasher too far out as the water supply and drain hoses could be damaged. Unplug the unit. Turn unit sideways and tip over onto its' back. At this point, the sump will have to be removed using a nut-driver and/or socket set. This will open access to remove the old pump connector. Replace the old connector with the new connector, and reassemble the sump, connecting and firmly tightening all connectors. Tip unit upright. Screw mounting bracket back into the bottom of the dishwasher and put the remaining parts back. Before pushing the unit back into it's nook, I advise running a quick cycle just to make sure there is no leakage. If there is no leakage, put the unit back, tighten the mounting screws and you're done.

The web interface is nice, however in this situation it references the wrong part which was not known until the item arrived. Customer Service handled return, however I had to call LG directly to confirm correct part number (LG p/n 4866ER0004A = p/n PS3524040) but this was only after LG also gave wrong p/n. When replacement part arrived the internal concrete had a crack in it. The part is basically a plastic shell that is filled with concrete. However the opening (about 1 x 4) is left open and with the concrete having a crack in it the piece will vibrate together and continue to break down over time (which is what happened to the original one) Before installing I chose to fill opening with epoxy and a plastic layer, then covered with electrical tape to seal it in. I feel this item is poorly designed from LG. Additionally this item was poorly packaged by PS when shipping which caused the damage (it weights about 15 lbs and was allowed to float around in a large over-sized box filled with large air pillows). I have photos but no way to upload here.

The repairman offered to fix the dishwasher at a cost of about $200 or supply the water inlet valve for $85. Google led me to PartSelect.com where I easily found the correct part for $45. I received the part in 2 days by FedEx ground.
The hardest part of the repair was removing the dishwasher from the cabinet. I took the dishwasher out a short distance to the patio where I replaced the water valve...about 10 minutes.
I then made a makeshift connection to an outdoor water hose and connected the electricity and ran the dishwasher while out on the patio through a short cycle to make sure of the repair and check for leaks.
Then reinstalled into the cabinet...total time about 2 hours.
Thank you PartSelect.com

get fingers between lower spray arm and drive flange - rotate arm counter-clock wise and lift off...the arm was warped and hitting inside of lower door liner.

Repair is super easy and anyone can do it in no time!
At first my fear was that it was the pump, but after reading through the trouble shooting here it narrowed it down to the water inlet valve. The new valve even came with easy to read and understand instructions. I had it fixed in less time than it took my wife to make us lunch lol.

2 screws hold the mount bracket in place. Just remove the screws, remove the c-clip that holds the secondary/small water line on, pop the hose off then remove the main water inlet line [ its the bigger line with the brass fitting ] I only needed a pair of pliers for this. Reinstall the main water line into the new valve, but make sure you use pipe tape on the fitting or you'll have a water leak. Reinstall the secondary water line and reclip the c-clip using pliers to squeeze the clip. Hold the valve in place and reinstall the 2 mounting screws. That's it your done !!

This is the second time I've used partselect, and they are hands down the best !! Other sites would have you buying part after part until you happened to get lucky and get the right one. Not here, they help you figure out just what you need and nothing more.
Great people and fast service !!
Thank you once again.

Piece of Cake; Part was O.E.M.Component Exact Fit; Took Longer to Write this than it took for Fix. Thanks I Will Be Back for other Parts.!

installed part on inside end of rail. no tools needed. original part wouldn't stay on rail. finished in 2 minutes
wife happy

We knew roughly how we needed to put the cap on the rail, but our technique of simply forcing it in the end of the rail wasn't working. The trick is to bend the moveable part of the plastic cap inward while you're sliding it in, and it clicks right into place.

The location of the cap we were replacing was the upper back left, which made it a little tricky to reach back there and insert it, especially for a bigger guy like myself. We took the bottom rack out and my smaller wife was more easily able to lean in the dishwasher and reach back there to insert it.

Easy repair-removed hex nuts and and screws to pop out old part and replace with new one. New part works better than the original! 1st replacement part arrived with a broken piece, a quick, courteous phone call got a replacement sent out. It took a 2nd phone call to obtain the refund, but the customer care reps are efficient and friendly. I would order from them again for positive service reasons alone.

Took the rack out. Took off the broken wheels and axles. Popped the new ones on, while replacing the rack. Piece of cake! Saved over $100.
