WM1815CS LG Washer - Instructions

The manufacturer recommends checking the inlet screens first then call for service if problem persists. I checked the screens on the fill solenoids, then I checked continuity for the primary wash solenoid and found that it was bad. I replaced the inlet valve assembly with parts I received from Parts select but I found out later that I had multiple problems. The main PCB had voltage at the main wash fill solenoid contact on the PCB even when the power switch was off. The machine would begin to fill when I would turn the power button on and when no wash mode was even selected. The drain pump would not drain the drum either. I ended up replacing the main PCB and the inlet vlv assembly and pressure switch and now the washing machine works great.I saved myself a boat load of money by doing it myself.

Hot water valve was leaking when washer was not in use and flooded floor. Advised owner to replace hit and cold water valve same time since only hot valve was bad. Hot water was easy but cold was difficult because it has the bleach and softener valve attached in one unto with three hoses and three wire connections. The opening at back of machine was small and you must have small hands to replace them. If not, then you have to remove top cover to get to it which is extensive.

1. Remove spring-loaded clamp assembly. 2. Partially pull out the large rubber gasket near the lock switch assembly to gain access to the lock switch assembly. 3. Unscrew two screws holding the lock switch assembly. Carefully separate the connector from the lock screw assembly and replace it with the new part. Reinstall in reverse sequence. Ensure that the electrical connector is fully seated unto the lock switch assembly and the connector latch is fully set against the lock switch body. Also make sure that the large rubber seal is fully seated around the door opening to prevent water leak. Restarted the washer and everything worked as before.

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.

Ordered a new water valve, easy installation, removed top cover of washer. Two screws and three hose clamps, done in 20 minutes.

removed 2 screws on back. removed top. disconected wires and hoses removes 2 screws holding assy in place and removed assy. put in new assy and installed hoses and plugs in same location removed from. reinstalled top and hose and ran washer.. new valve unite works but has a high pitched whine when valves turn on. :(

took out the drain pump and replace with a new one

During my troubleshooting, I removed the bottom to access the drain pump. I had to cut some wire ties so that I could make removing the wires easier. After checking the pump and putting everything back together, I determined that the pump itself was bad. Pump impeller should not rotate freely! After receiving new part, I installed it relatively easy. I didn't have to remove the bottom since there was enough room through the access hole. Just make sure to make where wires go before removing old part.

Loosened hose clamps to remove old bellows. That seemed simple but was awkward reaching into the confined space. Clamp adjustments were all installed facing away from access opening. New one went on easy and I reinstalled clamps facing the opening. Perfect fit!

Hardest part was getting the correct part. Due to some glitch somewhere there was a mix up in the database for the correct pump number. This unit has two pumps mounted to the same housing. One is a recirculating pump and one is discharge pump. I ordered the discharge pump and kept receiving the recirculating pump. Discharge pump is LG PART#4681EA2001T and recirculating pump is LG PART #4681EA2002H Once in hand the install went fairly smoothly. Removed top - two screws on back of unit. Removed control panel with one screw on upper right inside corner, associated plugs and snap clips. Removed soap tray and drained water through filter tube. Removed screws in front of filter. Using Vise grips stretched spring from around front seal. Removed screws holding front of washer to top frame (2?)[accessed after soap tray removal]. Pump assembly located in bottom left, removed associated hoses, Marked wired colors on pump housings and removed. Removed assembly. Unscrewed pump, installed new pump and reversed procedure to reassemble. Struggled mostly with replacing spring around front seal. Stretch it as far apart as you can as you "roll" the spring in and then massage the seal to get the spring into correct position. Definitely a doable repair. Good Luck.

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.

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.

First I turned off the hot and cold water supply and removed the water lines from the back of the machine. I then unscrewed the 2 phillips head screws on the back of the washer for the cover. I slid the cover back and lifted it off the machine. Next, I unscrewed the mounting screws from each inlet valve assemble located on the back of the machine by the hose connections. I used pliers to pull the hose clamps back from the inlet valve, 1 at a time, then reconnected each hose and clamp on the new inlet valve. Once each hose was connected to the new inlet valve, I discarded the old inlet valves. I then re-attached each inlet valve. I placed the cover back on the machine and secured with the 2 screws, re-attached the water supply hoses to the hot and cold side and turned the hot and cold water supply back on. Everything successful, no leaks, and washing laundry again..........leak free!

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.

I removed the top off the washer, unplugged from the electrical, removed the three hoses and wiring plugs, removed the two screws holding the valve assembly in place, and replaced the part with the new. It was a very simple swap, and I even found a video on YouTube on how to replace it.
