WM0742HGA (00) LG Washer - Instructions

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.

The problem ended up being the pump motor which discharges water from the washer. I figured out this was the problem after trying several things. I determined the motor was fine when it was empty. With the unit turned off, if you can rotate the tube with a quick spin and it lights up, probably this is OK. Then I tried to run it again and it went about 1/2 way through the cycle and stopped and started humming again. So I started emptying out the water, which I noticed was about 5 gallons which is way too much. so once empty, I took the pump off by turning unit on side. There are two hoses with hose clamps, and a few screws. Be careful to mark which wire plugs onto which side of the pump. One is brown and one is black. If you take the pump housing off, with the 3 screws, you should be able to pull the motor apart. Mine had water and scum from the wash in it, which was a dead give away that it was the problem.

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.

Took off the old one and put the other one on. The only difficulty was that my husband has big hands and had a hard time getting to one end.

The repair went well and your parts are easy to find. This is the second time I have used your services and both times have been great. Your parts are at great prices and your delivery is a lot faster that one would think.
Thank you

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

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.

Removed the old bellows (2 squeeze hose clamps and one screw adjustable hose clamp) slid on the new one and it was done!

It was so easy. i searched my model it brought up this site and the most common problem popped up without my even asking and recommended the part. i got it one week later and it was so simple to fix. a repair man wanted three times the part price to come to my home twice and would have had to wait longer. you guys were very helpful

Replaced rotor assembly by removing the back panel off the washer. Removed center bolt to be able to take out roto assembly. Magnets made it a little resistant, but with a little wiggling came off fairly easily.

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.

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.)
