WM3997HVA (ASSEEUS) LG Washer - Instructions

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

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.

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.

Simply took hose off from inside machine and replaced it with new one. The tore one had a stopper on one end that wrapped to front machine; inside filter compartment. So I put stopper on the other end of new hose and wrapped it to it's holding spot in filter compartment.

Super easy to find the part thanks to their diagrams. This fix was easy but I would definitely use this site again.

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

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

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.

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.

UNPLUG WASHER.Unscrew 4 screws holding silver plate at back of unit. Remove plate to expose inside of unit. Locate drain hose at bottom of washer tub. Hose connects at front drain, bottom of tub, and at rear at the pressure sensor. Front and rear simply slide clamps down by grasping clamp tabs and sliding clamp off connection point. Disconnect from tub bottom by loosening main clamp with Phillips screwdriver and pulling downward. Have a towel handy as there will be water in the hose, and it will pour out when removing it from the unit. Installation is the reverse of removal. ATTACH THE HOSE ASSEMBLY TO THE DRUM FIRST, THEN FRONT, THEN LASTLY REAR. This order is the easiest way, otherwise you will spend extra minutes trying to get the tub connection to seat properly. Plug it back in (duh), then you're good to go for another 4 years or so until another hole wears in the hose. I have performed this repair on 3 different units, with 4 years being the average lifespan of this part.

I received the part needed within a few days from ordering. I immediately removed the leaking part with the new part. It was a very simple install, and my washer is now leak free. If you think you cannot do these simple changes, think again, it's much easier then you may think. Remove the top cover of your washer machine by taking off the two screws in the back. Remove the hose clamp with a pair of pliers and pull off from the intake valve, of course make sure your water valve is shut off before starting. Remove the two prong clip. Using your pliers, disconnect the main hot water hose. Use a Phillips screwdriver to remove the two screws that holds the valve in place. Remove and discard it and replace with the new valve. Follow the steps and your done, it's that easy....TC

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.

The bellows hose on the bottom of the tube had worn through where it flexed. This was an easy job except for the long reach you had to make under the washer to reach the hose clamps that held the part in place. These were spring loaded clamps which were easy to remove with pliers. I replaced them with ones that could be tightened with a socket wrench since it was hard to replace the sprung clamps.

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.

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.)
