WM3431HW (00) LG Washer - Instructions

Pull the washer away from the wall to get behind it. Unplug the electrical power cord from the wall. I removed the top cover by unscrewing the 2 screws on the back of the washer. Slide the cover back about 1-2 inches towards the back of the washer and then lift the cover up and remove. It might be a little tight to slide back, you may need to wiggle the cover side to side or give it a good smack. The water inlet valve is directly at the top inside of the washer. I saw a slow leak dripping from the hot water inlet valve onto the back side of the drum. Turn off the water supply valve at the wall and then unscrew the supply water hose from the water inlet valve at the back of the washer. Disconnect the electrical connector and water hose from the inlet valve inside the washer. From the outside of the washer on the back, remove the screws holding the water valve and lift out the valve. Install in reverse order.

Some screws, some clamps. Easy and straight forward. unplug machine, turn off water, disconnect water hose, unscrew top of machine (2 philips head screws), disconnect clamp from valve (use a towel for remaining water), disconnect wire, unscrew from place holder, remove entire valve, work backwards from there.

new pump was a little different ,but mounted properly. Tipped washer on its side, changed pump by working trough bottom and back access. It went pretty smoothly, works fine.

Disconnected power. Removed washer top; only 2 screws in back. Disconnected two wire connectors on Filter Assembly Circuit. Removed assembly; 1 screw. Installed new assembly, reconnected wires, and replaced washer top.

pulled off top of washer to get at the inlet valve disconnect two hoses take two screws out and then you put it back together the way you took apart and your done

Unplug Washing machine first. Then remove 2 screws at the back of the top cover. Slide the top cover back then lift and remove. Unplug electrical connector @ inlet valve and remove water lines 1 going in and 1 out of valve. Remove 2 screws holding assembly in place then install new valve assembly and all other components in reverse order.

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.)

removed top, removed 2 screws, replace part. did not fix problem, the real problem was the water inlet valve, works great, easy fix. thanks

Removed lid (top of washer), then ran a cycle in normal to identify the failed component, then noticed the water inlet valve assembly for the hot water was leaking, used my pc and went to website Part Select and found to failed part on the parts break down item, then ordered the part, the part "Valve Assembly Inlet" for the hot water arrived 2-days later, replaced valve in less than 5-minutes, disconnected push on electrical connector, unscrewed the valve assembly inlet and installed the new valve assembly inlet, very easy

found the leak, went to the website, called customer service, ordered the part... $24 later, problem solved. Great customer service and on-line support

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.

Turn off hot water supply and activate a cycle on the washer momentarily, with hot water selected on front panel options to relieve hose pressure. Slide washer out to gain access to rear of unit. Unplug washer from AC source. Using pliers, remove washer supply hose from washer-side of the line (water may drain from hose) Remove single Phillips screw at bottom of each nylon lid holder at rear. Using a plastic putty knife, place between front panel and top lid to loosen lid and slide to rear. Remove lid and store aside. Hot and cold inlet valves sit side-by-side at top rear of the unit. Disconnect connector from valve by pulling gently away from valve plug prongs and place to the side. Using pliers, compress hose clamp and move to lower section of hose. Carefully rotate hose back and forth to remove from assembly. Inlet valve is held to washer body rear with 3 small Phillips screws. Remove first 2 and then while holding inlet valve body, remove final screw to free inlet valve assembly. Replace with new assembly by reversing these steps.Make certain when supply hose is reconnected, it is firmly tightened but DO NOT over tighten. Test washer by running a cycle to ensure there are no leaks.

Removed screws from door, not hinge, replaced handle, reinstall screws and you're done!

I watched a video of how to replace the pump and it showed taking the top and front off to get to it. I actually found this could be done by removing the back panel from the washer. There were two hose clamps you have to squeeze and slide up and two wires going to the pump. There are three screws holding the pump that need to be removed from the front of the washer. Once these are removed all you have to do is push a tab down and the motor slide right out. The pump assembly can also be reached from the bottom of the washer.

The machine was making a grinding noise instead of draining. I spoke with the LG rep on the 800 line and was told to call a repair man. The Parts select diagram helped me to identify the part I needed. It was clear enough that I was confident it was the right one. Three days and six screws later the machine was working fine.
