Why NSI Protection Plus?

Our service plan is an economical way to extend the terms of your product's manufacturer parts & labor warranty.

Most manufacturer's limited warranties leave customers with no protection against the rising cost of repairs.

Even the best products can malfunction and the most minor repairs can cost hundreds.

About NSI Protection Plus

Administered by Warrantech and insured by AmTrust Financial, NSI Protection Plus is the largest service network in the industry with 30 years of building the network and over 22 million in paid claims.

The most comprehensive repair plans in the business!

  • Day one coverage on special features
  • Removal and reinstallation coverage
  • $25 Laundry credit (Washers and Dryers)
  • 5 year appliance contracts include 10 year major component coverage
  • $250 Food credit (per incident, eligible products)
  • The only true "No Lemon Guarantee" in the business
  • No "CAP" on repairs or replacement, unlimited repairs.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Follow-up 4.8 now that I have learned how to use

juce2 12/15/2020

Week two and after 3 weeks and one hunting trip worth of laundry including 3 comforters I think I have learned the machine. Normal wash/dry is 3 hours and 18 minutes. Some folks say that is a long time but that allows you to work play golf or cook and eat dinner without having to stop and put your wet laundry into the dryer. I washed 100 cotton napkins that have never been unwrinkled even after ironing and they came out perfect. The space used to fit one of those annoying laundry centers with the tiny washer and yet I have more space in the front and sides of the unit. I will be able to add a clothes rack and drying station for the delicate items in the same space. I am still annoyed with the lack of instructions not telling us you have to set the washer then the dryer and not being able to set the dry setting with the bedding wash setting otherwise it would have gotten 5 stars. Use the anti-slide pads and dont follow the loading photos causes the banging noise just load like other washers just more sorting of like with like i.e.. towels with towels.

Huge learning curve

Juci 12/8/2020

Just got it today 1st load done quickly but had to manually hit the dry button to run the drying cycle 1:20 minutes Normal wash cycle 45 minutes. 2nd load is taking much longer-husband chose the setting and hit the dry cycle button I think. Hours at this point-operator error? Manuals do suck and the WM3998HBA cant be found. The 2nd LG Chat person figured out drying cycle issue have to chose the wash setting and then chose the DRY setting then hit the start button. Have to try that next. Will update as I get to know the machine.

Do not buy this item

Daneenk 10/20/2020

I bought this a couple of months ago and not only are the manuals not that helpful but the this washer dryer combo takes 9 hours to wash and dry a complete cycle. Im not exaggerating. If you have all day and all night to do laundry then go ahead and buy it but I do not. Oh and if you cant remove the dry laundry immediately it gets ridiculously wrinkled and does not have a dry only cycle so not only do I wait 9 hours to do my laundry but then if the dryer stops why Im not at home I have to spend another hour pressing all of my clothing. I literally hate this machine.

Brand New to LG Combination Washer/Dryer

James in BC 10/14/2020

So far so good except for the manuals provided. There is very little information in the Owners Manual and even the online manuals make to reference to dryer functionality. On my first wash load I had to activate the dryer manually so Im not sure what Ive done wrong. Trying load #2 now and will see if Ive set it correctly..

I regret buying this product

JCB5673 10/4/2020

This product is fine if you dont mind having to do laundry twice as often and if you have twice as much time when you use it. The dryer takes 2-3 times as long to dry a load as it does in a normal machine and you can only dry small loads at a time. And in addition its very complicated to use and the user manual is of little help.

No manual with unit how to operate dryer

Bob Lib 9/30/2020

Just bought today. No manual saying it is a dryer combo. Panicked thinking I ordered the wrong unit. Apparently customer service says you have to put in dryer function after wash cycle. This is not why I purchased this

Got ours yesterday. So far we love it. The major issue we do have is that the instructions that come with arent specifically for this unit although it says it is. There arent any instructions that mention the drying function at all. Really would like instructions that are useful and complete.

Doesnt have to be vented.

Bevw 9/11/2020

We have had our LG washer/dryer in one unit for over 15 years. We had to get it in White because that was all that was available at the time. We live in a condo and cannot put a vent in the wall. This was and is our perfect option I am so glad to see they do have it in black now it will now match my other kitchen appliances. Very Very happy. It takes longer to dry but that is OK with me I do not have to leave my apartment and go to a laundry mat or room

I have had two of these

Elarson52 8/28/2020

I love this all in one. I had one and when the ball bearings wore out after 10 or so years I immediately got another. I am one of those that forget to move the wash from the washer to the dryer and had to rewash. This solves that problem. I agree that this takes more time than a washer and separate dryer but it is not a problem for me. I do not have a large family and only do a few loads a week. I love that it can just sit in a closet and I have no dryer duct to clean out and worry about starting on fire.

Love this machine

Golddog 8/28/2020

We have the previous model of this washer/dryer combo and have had it for 3 years. It performs flawlessly. Clothes are cleaned well it does take a while to dry but that is to be expected with a condensing unit. A full load of sheets or towels takes only about 3 hours start to finish and that is perfectly acceptable to us. If one has a large family this may not be the type of unit to get as it does take longer but for the two of us it is just fine. I highly recommend this for those who want to save space save electricity and have clean clothes.

Doesnt actually clean clothing

Alleycattt 8/5/2020

Purchased this combo to save space in our lake home. I cant understand why it wont properly clean our clothing. It leaves our clothing still dirty and smelly Its awful and i cant figure out what were doing wrong. It only seems to some what work when I only wash and then open the washer to only have to set it to the spin and dry cycle which takes forever. Washing pods would not work and only leave our clothes stained and the pod half drained and dried into our clothing ruining it. So I then switched to liquid detergent with not much improvement. Really disappointed we had high expectations but its really become a waste of time and energy. I cant figure out if were doing something wrong. We love that it saves us space but it defeats the purpose of our clothes are still clearly dirty

Incredible Machine

cosmo3405 7/30/2020

I bought the LG all in one the first year it was offered and that machine is still in service in my home. The only thing I have ever had serviced was the drain hose. My experience has been so great I bought another one about 2 years ago for my condominium at the beach. Many people dont understand they are benefitting from super clean clothes the convenience of not having to move a load of clean clothes to a dryer everytime and tremendous savings in water and electricity. Operation has shaved $60 a month off my utility bill. I hear people griping about the drying function. Yes I give my clothes one good shake before I fold them but thats it. I would never go back to two separate units. Thank you LG

Nothing

Denise82 7/22/2020

Purchased Model WM3997H*A a couple of years ago. After 1 1/2 years had to replace a something to do with the drum machine would not spin. Four months later 4/2020 same problem had to replace the same part again. Now 07/2020 again machine will not spin. Worst investment I ever made. Going to purchase a separate washer and dryer and throw this machine to the dumpster. I am so disappointed in this product and do not recommend.

Exceeded my expectations

JAM52MY 7/19/2020

Desperately needed additional space and couldnt use a separate washer dryer. The ventless combo unit was the solution or so I thought it was. Agonized for months on which way to go let alone which manufacture. After reading all the reviews over and over again I settled on the LG it consistently had the best reviews. I can do full loads without removing half for drying as most recommend. The dryer runs longer than a standard dryer but not excessively. Expect some dampness when the drying cycle ends but its minimal.

Just Right When There is Nowhere to Vent

JIGITYJO 6/30/2020

The unit was delivered about a month ago. We chose it because of limited space and nowhere to vent. Unit does exactly as described. Washes and dries. Takes a little longer but very easy to use. We also bought the sidekick unit for quick small loads. Very happy so far. I also really like the sanitary cycle. Takes the stink right out of exercise clothes.

Awesome

GGWILL0 6/28/2020

I just got this to replace 8 year old washer/dryer set. It is awesome Yes it takes round trip for me about 4 hours per load. If you pull items out right after the cycle it is slightly moist but once out in normal air it is dry and fresh. Ive done my bedding clothes towels and dog bedding all without problems and am very satisfied. A lot of people ask about just drying its easy 1. Turn on. 2. Press Dry and select setting. 3. Decide if you need spinning if really wet you will want to leave it on. 4. Press Go. ...... Now i have an extra outlet more space Im using less water less power less detergent and cleaner clothes

Impressive Performance

Cory123 6/20/2020

I have owned this W/D combo for just over a week and I am truly impressed. I previously owned individual washer dryer units and expected some trade offs when going to a combo such as long dry times and items not being fully dry however I have been pleasantly surprised While the dryer does take somewhat longer everything consistently comes out fully dry and with little to no wrinkles. I have found that the WM3998HBA performs best when you fill the drum about way and use a fabric softener to reduce wrinkling. Downy Fabric Conditioner gets great reviews and works well The drum is very large so even when full its quit a bit of clothing. Run time varies depending on what settings you select. The average wash/dry time using the Normal wash time and Turbo Dry has been about 3.5 hours for me. Using Normal as the dry setting bumps this up to 4-4.5 hours depending on the load. My only criticism about this unit is that lint collects on the door gasket. Manual lint removal isnt perfect but running a load of laundry that I plan to air dry washes most of it away. Im hoping to find a better solution for this soon.

Alex Fox 6/6/2020

Just got this today. Works like a charm. Love the sleek look. Super quiet. Setting up the wifi and phone connection was easy. Takes a little longer to dry but worth it for only running on 110v instead of 220v and NO VENT HIGHLY Recommended appliance.
