WM3988HWA LG Washer - Instructions

Basic skill

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.

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.

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

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.)

unplug washer and disconnect inlet and outlet hoses. drain water from washer (about 2 gallons) by removing lint screen from front of washer. lay washer on side (I used a blanket to avoid damaging the paint) remove all the phillips head screws in the plastic bottom and the metal feet of the washer. Gently pull the bottom of the washer off. There are 3 shock absorber looking things that pull apart and are greasy. Try not to mess with them much. Just pull gently, and they slide apart. cut the zip ties holding the wires to the washer bottom piece. remove the screw in the lint screen area and gently pull the recessed plastic thing out the front of the washer. remove the screws holding the pump assembly on the front of the washer. Remove the three screws holding the pump assembly on the outlet pipe manifold. Installation is the reverse of removal, take care to put the shock absorber looking things back in gently and together at the same time when reinstalling the plastic bottom of the washer.

Tilt the unit back. Remove screws that hold the clean out. Disconnect the electric plugs and hoses. Remove pumps and housing. Change out pumps. Put back together reverse order

greate very easy and the parts fit awsome the shiping was fast and easy very satified

Found great Youtube video, followed step by step. Only difficult part was getting the tub gasket clamp back on. But all in all pretty easy. If tub won't drain and weird noise coming from pump do not hesitate to do it yourself and save some coin!

The pump is apparently used for more than one washer, and the R&R instructions may be significantly different. I found a youtube video for my exact washer.

Removed the top, the front, got to the pump, removed it and replace it with the new one.

Found the part of Part Select by describing the problem. used a Utube video and step by step we were able to take apart, replace and put back everything with just a screw driver - I saved so much money!

Found on line OE meant washer not pumping out water with the suggestion to clean the filter and inspect the pump and lines for blockage. No problems there. You must be careful to empty the water manually before removing the filter. My wet vac helped but I still made a mess. I found a mechanic to look at the washer. He said it is common for the pump on these washers to go bad, especially if the washer has sat out of service. They wanted $300 to replace the pump. I found the part on this website for $53 and replaced it myself. The only hard part was emptying the water without making a mess and leaning the washer up and back far enough safely to remove the pump, then working on my back under the machine.

My washer would try to spin and remove the water according to the time allowed. Consequently my washer would take longer than the time allowed to drain therefore water would send a code error then the machine would stop working. So I remove the hose from the pump and found my son's little small sock blocking the drain. I removed the sock and reinstalled all hoses. Everything is fine now. No need for a replacement item. Just a little servicing.

Took apart the washer and removed bearings and shaft on spider. My advice would be to order the spider and shaft (one piece) hen ordering the bearings, seal, and tub gasket. If the bearings are gone, it is likely the shaft is gone too as mine was.
