WT4870CW LG Washer - Instructions

After getting the model info from the back of the washer control panel, I searched Partselect for the water valve part. Easy process, It was here in 2 days. Unplug the machine, I took 2 screws out of the back of the control console and tipped it forward to reveal the valve assy. Turn off the water at the wall and disconnect the hot and cold lines from the washer . I removed the 3 screws holding the valve assy to the deck and with pliers disconnected the 2 clamped rubber lines and then with just finger pressure wiggled the valve from the remaining pipe connections. I swapped the 5 wire connectors to the new valve and wiggled it back into place. Clamped the 2 rubber lines again. and then connected the water inlet hoses to the new valve. Closed it up and called the laundry lady ( sorry honey) 30 minutes to Household harmony again!!

Move the washer to the garage and laid it on its side. Remove the large nut from the center shaft using a crescent wrench. Tap the wrench with a hammer until the nut comes loose. Next you'll need a puller to remove the part that was secured by the nut. Mine would not come off by hand. Next remove the three screws securing the white plastic components to the bottom of the washer. Remove the two plastic pieces and throw them in the trash because I'm sure they're garbage. Reverse the process for installation and reinstall the washer. Put some clothes in for the test wash and the washer should be silent. Two different appliance repair folks gave me estimates that were higher than the cost of replacement. I got out from under this fix for around a hundred bucks. It was worth every minute of my time. Good luck.

Getting the old part out was not too hard, but had a couple challenges. Watched a video from RepairClininc that detailed the process very thoroughly. Definitely use an impact gun to remove the drum nut inside the drum. My drum was stuck on the shaft pretty good. Would not lift off. Removed the rotator, stator and diverter motor on the bottom, and took out all the bolts securing the clutch. Had to use a hammer to tap the shaft out from inside the drum. Then the clutch dropped out the bottom and I was able to remove the drum. Installation went smooth. Just remember the order you took stuff off and the position of the parts. They need to go on the same or the electrical connectors won't reach.

Removed the center cover cap carefully on top of the agitator with a small screw driver. There are 3 (on mine) little slots around the edge of the bottom of the cap where it meets the agitator. Insert the small flat blade screwdriver and gently twist at each one till the cap pops loose and comes off.

There was a 10MM bolt under the cap on mine that you need to remove. I used an cordless impact driver but you could use a socket wrench as well. Remove the bolt and the agitator comes off. May take a little wiggling or it may come right off.

The teeth on the agitator were wore all the way down and gone on mine so it came off easy and this was the issue I had why it was spinning freely. I took the small flat blade screwdriver and used the edge and corner of the blade to clean the teeth on the shaft where the agitator attaches and wiped it down before installing the new part as there was quite a bit of metal shavings from the damaged part.

I just reversed the order of removal to install the new part. Took about 15 min. I ran a rinse and spin cycle to remove any additional metal shavings and to check to see if it all worked properly. THATS IT! TOO EASY!

I found the pulsator just spun freely, I determined the hole on underside should ribbed to align with the ribbed shaft. But it was wore away. I purchased the new part and replacement was simple. It slide right on and I replaced the bolt. Pulsator works great, washing again.

Figured out how to remove the top door and the top panel that covered the solenoid bank. That was the hardest part. Swapping out the solenoid bank and the connector was easy. No more water leaking.

I noticed that my washer was leaking water into the tub. It was dripping, very slowly, but it was dripping. I noticed first, because it was starting to smell, and I didn’t understand why. Once I noticed that it was dripping, I checked online and noticed that the solenoid water inlet is most likely the problem. I found the part on parts, select, and confirmed with my model. The pictures were very close and similar, so I was pretty sure I was getting the cracked part. Once I received the part, it was time to fix it. You just have to turn the water supply off, remove the inlet lines with a adjustable wrench, if necessary, and then get to the washer. Make sure you also unplug the washer. There are only two Phillips head screws to remove to get the vanity cover off of the back. For whatever reason my removal was a little bit difficult for this. There are some plastic clips that hold the front portion on of the vanity plate. These were very tight, and I was afraid I would break them, but eventually they came loose with gentle upward pulling. Once this was off, it was super easy to identify the part that needed replacement. There are two hose clamps that you just need a pair of pliers to squeeze in slide off the hose. Then you remove three additional Phillips head screws, and the other connections pop out on their own. The solenoid plugs are very simple to slide off, and it is really difficult to put them on any other way. If you need to, you can take a few photos of the installation. Once you have the old one out, hook up the hoses first, and slide the hose clamps back to their original position. Once you have the two black hoses back on, reposition the new valve body, and slide the additional three prongs into the inlet soap dispenser. Make sure that the fit is snug. Don’t over push, the parts are plastic. Once this is done, reinsert, the three Phillips screws into their holes. Then you can reconnect the solenoids. At this point the replacement is done, and all you have to do is replace the vanity cover. Take time to ensure that you’ve done this correctly. I left the vanity cover off and ran a test load of dirty clothes to make sure that there were no leaks. Once I assure, there were no leaks, I put the vanity cover back on and put the two screws on. This was a very easy fix. Again, just go slow removing the vanity plate so you do not crack or break the tines in the front.

Replaced valve body, very easy to fix as per the video, runs normal.

After unplugging the washer I cut the water off. I took the water hoses off, then the back top panel using a phillips head screw driver. I then used a pair of pliers to take off the two hoses and clamps. I unplugged the electric connection on each solenoid, took out 5 screws replaced the part and did everything in reverse order. Problem solved. Thanks for the fast service on my order.

The teeth in the pulsator assembly where stripped out on the original plate.

Ordered the replacement and it was 1 screw to undo and pop in the new assembly. Super easy repair

I can’t really say it was easy and I just did it

Remove the bad motor assembly ac pump with the new one.

Our Samsung HE washer started making a grinding noise and stopping at the end of the rinse/spin cycle. I had replaced the clutch and seal 2 years ago and it sounded like it was going out again, however we were not getting the gunk inside the tub like before (seal) and the machine was throwing the tE error code when it stopped which it did not do last time. According to the manual this meant a thermistor error and the solution was "Call for Service". The machine is 9 years old and way out of warranty so....uh No! I ordered the new thermistor for $15 plus shipping to correct the tE code before looking to replace the clutch again or get a new machine. The new thermistor arrived, leaned the machine on its back, unplug one connector, remove two screws and pull the old one out of it's hole, push the new one in, replace two screws and the connector and GO! Problem fixed! No tE code, no stopping, no grinding noise. As best I can tell, the old thermistor was faulting during the spin cycle and the machine went into emergency stop mode which made the grinding noise. It was not the clutch or bearing at all. Most of the repair time was moving the machine out and disconnecting lines so I could lean it onto its back. Note: If your machine is stopping before draining, it will have water inside the tub which will drain out of the hole where the thermistor goes when you pull the old one out. It has an o-ring to seal it, so just expect a little water to come out and be ready to catch all the water or put the new one in quickly.

Everthing went to plan except the wet side of the parts removal was difficult. used puller to remove the wash plate and got it to release. But the plastic part of the wash plate released and left the aluminum part still on the coupling. Corrision was the problem, and I had to again use a puller to remove this part of the wash plate. So it wasn't a matter of just lifting the wash plate off by hand. The rest of the replacement was fine.

Unplug washer. All work can be from back of washer. Remove 2 wires, 2 hose clamps and hoses, 3 mounting bolts. Reuse mounting bracket and replace pump in reverse. Run wash to check for leaks, repair if any. Return washer to original location.
