Washing maching wouldn't drain

Removed the top of the washer by removing the 4 back screws and 2 small brackets. Then I removed the front panel, this was actually the hardest part, 2 screws and 8 tabs that you pop out carefully from the top of the panel. I only disconnected the power button and was able to rest the panel on top of the washer. The rest of the washer came apart quickly just moving down the front of the washer and removing the door, latch, tub gasket, drain cover. Removing the pump was just a mater of disconnecting the drain hoses, and one clip under the drain assembly. 3 screws attach the drain to assembly to the pump and only 2 wires that are clearly marked. Reassembly is just going back through in reverse order of disassenbly. The best thing about this is that it all comes apart with a standard phillips screwdriver.

Unit would not start up

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.)

Cloged Drain

My washer would try to spin and remove the water according to the time allowed. Consequently my washer would take longer than the time allowed to drain therefore water would send a code error then the machine would stop working. So I remove the hose from the pump and found my son's little small sock blocking the drain. I removed the sock and reinstalled all hoses. Everything is fine now. No need for a replacement item. Just a little servicing.

Washer not spinning and giving error message OE

Found on line OE meant washer not pumping out water with the suggestion to clean the filter and inspect the pump and lines for blockage. No problems there. You must be careful to empty the water manually before removing the filter. My wet vac helped but I still made a mess. I found a mechanic to look at the washer. He said it is common for the pump on these washers to go bad, especially if the washer has sat out of service. They wanted $300 to replace the pump. I found the part on this website for $53 and replaced it myself. The only hard part was emptying the water without making a mess and leaning the washer up and back far enough safely to remove the pump, then working on my back under the machine.

After checking for blockage on the drain hose and checking on any blockage on the bottom left corner filter and not finding anything i decided to open the machine. Everything suggested a broken drain pump
ITEM
PS3579318 Drain Pump and Motor Assembly which is located on the bottom left corner also and it attaches to the bottom left corner filter. And voila! The machine did not work! Now started throwing a FE code and it would not fill up. Well, the new pump was stuck! All i had to do was to stick my fingers in the bottom left corner filter orifice and move the fan like devices that make the new drain pump work, that did it! Be careful not to do it while the machine is pluged in, those plastic blades may hurt your fingers. To reach the drain pump you have to take the top, control board and front (door and gasket) of the machine off, about one hour labor.

Drain water was not being fully pumped out, leaving foul water in the tub and wet clothes smelling like sewage.

I removed the top of the washer, pried the front control panel off (pull a couple of electrical connecters or just rest it on something), separated the tub sleeve from the front panel and then removed the front panel (two screws). To remove the pump - just remove a couple of hoses, two wires and slide it out of the clip below. Reverse the process to install. A little daunting if you haven't done something like this before, but easily do-able once you get past your fears. A service call would cost much more than the $60.00 it took to get the part to my front door. This worked out really great - my wash smells fresh once again and my wife has moved on to the next project on her honey-do list!

took lid off of washer (slides back, not pry) and had to dismantle from springs, rubber around door and pistons on bottom. also had to disconnect from electrical plugs and took out dispenser drawer and all hoses. also have to take off magnetic piece devices from off back of drum. mark everything before dismantling with a black permanent marker so you will know what went where when putting back together and what pieces were facing up,top, etc. once get everything freed up, entire tub pulls up out of the washer. get old shot bearings out of drum, but be careful not to beat on it too much so that you don't damage the shaft or "oblong" the tub, etc. ordered parts that arrived in about 2 days. to put new bearings back in, get large washers -one for front and one for back -same size as the bearings so you will have equal pressure coming from front and back, put a long bolt thru the holes in the bearings with one of the large washers on each end. put a nut on the end of the bolt and begin to tighten. this will pull the bearings together back into their positions without ruining them and gives you equal pressure all around. be careful when you get them tight, they will fit snugly back into place. put it all back together carefully, just like you took it apart. if you labeled everything, you should have no problem putting the puzzle back together. before putting the tub pieces back together, i ran a bead of silicone caulk to prevent leaks. started it back up and runs great! fixed it for total of $72 (including shipping charges), which is a lot cheaper than buying a new washing machine. it is tedious and somewhat challenging, but if you are in any way mechanical, you shouldn't have any problems.

The washer kept displaying "tE" error and the machine would stop.

First we unplugged the machine. Then turned off the water and disconnected the hoses. Pulled out the machine and laid it on its side to access the themsistor located on the drum. (No, you do not have to remove the control panel at all to replace this part) The thermsistor is clearly seen with a flashlight. There were plastic ties holding the wires of the thermsistor so we used small scissors to cut the ties. Then unplugged the old thermsistor and plugged in the new thermsistor and used a regular bag twist to secure the wires. Repair complete and the machine is back to normal. Thank you Part Select.
