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.

I waited 6 months to receive my washer/dryer all in one machine combo which was very irritating but it was worth it I LOVE it I love that it switches from wash to dry on its own without my having to switch all the clothes. I love that its quiet...mine is in my bedroom but I could run it while Im there and not feel disturbed. It washes a large load and also blankets sheets etc. The reason for 4 stars instead of 5 is because of the lack of instructions...in fact when I first received it I thought it was just a washer. There was no mention of the dryer function in any of the literature...I had to download the instructions with an app and even then theres just a few paragraphs about the dyer function. That is disappointing. Originally posted on lg.com

I have had this washer dryer combo for over a month. It does not dry the more you try to dry it the wetter your clothes get. No one in customer service knows about the machine nor their service representative. Originally posted on lg.com

After a few weeks of use I can say that this machine is pretty great there is a couple downsides but if you take my advice you cant go wrong 1st nowhere on this product does it say that the drain hose needs a specific orientation but IT DOES. We couldnt bet our clothes to dry because the hose travelled upward to far and wouldnt allow the water to drain all the way. The fix for this was to put a pedestal under it so that the drain hose was near level to the sewer drain in the wall. So only buy this if you plan to drain to the floor or put on a pedestal. 2nd frequently check the filter and clean it out it will get quite full after some loads go through it. Now all that being said it runs great and we love it now Originally posted on lg.com

Ive had the machine for about a month and a half at this point and I couldnt be happier so far the drum capacity is perfect could do all of my bedding in one load While the timing can be a little long you have the ability to leave work or sleep and all the while you can monitor it on the app or even delay the start if you know youll be away for a while. I would recommend this machine to anyone who can get by with 1-2 loads a day unless they are small you would be kind of pressed to get more in. My times so far have been from 2.5 - 7.5 bear in mind the 7.5 is everything fabric I wore / used that week including towels and dish rags. The 2.5 was about 3 outfits and 2 towels. For me I typically only do 1-2 loads a week so for me this is perfect and makes daily life a lot easier My favorite part I think is the ventless drying my house smells so good when it is running I would have given 4.5 if it was an option I abstained from a 5 star because of price and for the manner in which you have to clean out the lint it static clings to the rubber ring around the door and this can be a little cumbersome to clean not bad though just not as easy to maintain as a standard lint screen.

Ive owned the unit for 1 year. Washing on the short cycle takes 20 minutes. Great Drying on the other hand takes 2 hours and things are still damp sometimes. Overall I like the idea of one tub to do both. Originally posted on lg.com

I am yet to try this washer/drier in one combo unit The first one I got was defective where the drum was scraping against the back metal so we had to go through the replacement process. Just got a replacement unit and the plumber we called was not familiar with how in the world this washer supposed to dry? Where is the lint collector? Well the machine is looking great even though its not connected yet. I guess I will have to wait and see for myself Hope it will all workout for the best Originally posted on lg.com

This machine has been great. I was looking to replace my two front loader units and started to notice these after a this old house episode. My friend had one in his RV and loved it so I decided to check it out. You need to fully understand how to use it and read the manual as it is not a traditional dryer. The key is to make sure you are drying like materials and to not overload it like you normally would with a vented dryer. The turbo dry setting works good for shirts and undergarments while you will need to set it on normal for towels and heavier garments. Some clothes may feel damp but if you shake them after taking them out of the dryer they will flash dry. Once the dry cycle is done you need to wipe it down to remove the lint inside the drum gasket and door as there is no trap. Also you can not use dryer sheets but thats ok since static is not a problem since it used humid air to dry. You may need to watch out for a small vent on the back that blows out the humid air from the machine. The water lines are right in front of it and moisture condensates and drips from them during the dry cycle. I minimized this by rotating the waterlines out of the way but I wish the water lines or vent were located in another area. You may also want to be sure you have some moisture resistant drywall or coating behind the unit were it will be located as condensation from the vent can collect there as well and drip to the floor. It is not a major problem but something to keep an eye out for. Originally posted on lg.com

I bought this product through Home Depot and it does everything I expected it to do and more I love the fact that I have only 1 unit and that I can start a load of wash and in 3 hours and 20 minutes later my load is done. This allows me to maximize my time at the cabin enjoying the great outdoors without the interruption of having to stop what I am doing or having to stay close by to move my load of clothes from the washer to the dryer. And the fact that this is a vent less system is even better for an open concept log cabin. Originally posted on lg.com

I knew what to expect from this machine and I am glad that it exist on the market It is a savior No more laundromats for me I dont use machine that someone else uses. Yuck Yes if you would like to dry towels it takes a while..I have a laundry rack for that purpose and I dont mind at all. It dries well everything else it sanitizes it washes properly and gives you freedom. You can use the app for remote control which is great for busy people. More than happy with the product Thank you LG Originally posted on lg.com

This was exactly the washer I wanted. LG has been a good brand for me in the past but... I bought this washer two months ago. I have yet to complete a single load of laundry. Some sensor is malfunctioning and throwing a error code. After nearly three weeks I finally saw a service tech who said he didnt know if he could get parts or if that would fix the problem. Over a week later LG has not even responded to this information. Originally posted on lg.com

This was actually a gift from my parents and sister and brother in law and with a small area for laundry it is perfect I love all the features and how quiet it is as well. The only thing is the manual doesnt give any information about the use of the dryer. I have had to figure that out with trial and error. Great product Originally posted on lg.com

I like the large drum size. Most negative responses to this device seem to reference the length of time it takes to run a load. So what I dont mind throwing in a load and then going about my day Great energy saver If you only do laundry once a month with giant mounds of dirty cloths this probably isnt your best choice.

This unit washes and dries well. It does take a little longer but I have a small household. If you want speed then do not get this. Also some of the reviews on here are kind of misleading. Those that complain are probably not telling the whole story and Im willing to bet its operator error. Word of advice though DO NOT use pods in this unit because you want little to no suds in it. Trust me it will get your clothes clean. Originally posted on lg.com
JenBB 5/11/2021
Pros: Its so quiet you barely hear anything. So many cycles for the type of load that youre doing very easy to use and the app is really helpful. The size is more than enough for 2 people and a kid we struggled to fill it up. You dont really need fabric softener at least not for static since it doesnt take moisture out as much as traditional dryers. Cons: connecting to the app and the app doesnt allow you to dry. No instructions for drying I mean cmon The dryer just takes some getting used to. Overall I love this machine and am glad I didnt opt for the traditional washer/dryer. It works well is super quiet and I can get on with my day. The dryer takes a bit longer and you might think theyre not dry until after you take them out and realize that yes they are. I set it for 2.5 hrs and it usually gets everything dry. Just tried the turbo which showed 7+ hrs but ran less than 3 because its constantly monitoring your clothes to see where theyre at which is super handy. Ill probably use that from now on.

The washer does an excellent job of cleaning clothes. Has great selection of cycles to choose from. Dryer performs great. It does take longer to dry a load but thats no problem because Im not in a hurry for load to get finished. Actually for sheets and small loads there is not much difference to wash/dry a load in this unit vs. a conventional dryer. Quiet operation. The one draw back I have is that lint builds up around door window and door gasket after drying. Originally posted on lg.com

Bought this washer/dryer combo and it walked right out of the laundry room. Vibrated so bad and never did dry the clothes The LG technician that came to do the repair had said it was because I washed a blanket with 3 old towels. And then he said he makes over $200000 a year repairing crap machines like I bought. The gasket was completely mangled. And this is my fault? Originally posted on lg.com
Kim Kingrey 4/23/2021
Terrible instructions lead people to believe it will take many hours like 7 do run a full cycle but that is not true. Manuals and customer service dont tell you it takes the machine 4/5 loads to really calculate and not to be scared when the first few loads read 7/8 hours. It will adjust itself part way into the cycle. It feel this is why its got less than stellar reviews. An average load of sheets is about 2.5 hours start to finish I love it We own a historic home and were very limited in space - this works Originally posted on lg.com

We purchased in Dec 2020 and patiently awaited the February 6th 2021 delivery We live in another state and chose this unit for our family home where we visit semi monthly. We have managed just a few loads and even managed 2 loads when we arrived just to land an error code on the 3rd load - the diagnostic stated it is a Drive problem and to contact a repair facility. Hubby did and they arrived on time as scheduled - great However - they didnt stay to ensure it was fixed and ran it through an empty test cycle which landed the same error dHE Hubby called the repair guy who says he needs to call LG. So now we wait to hear back from the service team. We have to head back home - so tomorrow 4/22 is it until we can get back 4/29. Hope this can get resolved quickly We did get the extended warranty...if they need to replace it...thats fine - just want it to work as beautifully as it did We understand stuff happens...we need our washer/dryer to earn its purchase price :- I will update review if able once it is resolved.

I bought this specifically because it can wash and dry and doesnt require venting. The drying time is quite long but I expected that so its fine. The features are quite easy to use the cleanout on the bottom is easy to get to and doesnt cause us any problems. Certain HE detergents still create a suds error but weve eliminated that brand. The turbo wash does a particularly good cleaning job in a fairly short time period. It has some smart features that are helpful. All in all Im very pleased with this purchase.

There are definitely pros and cons with an all in one machine. For our household I am a chronic pain sufferer and often struggle with changing the laundry in a timely manner and thus often have to rehash the laundry. So while this machine means smaller loads and longer wash time the load is complete the first time around reducing my water usage and the damage/shrinkage on the clothes. I find myself staying on top of my laundry more because Im not afraid to start a load when I dont know how Ill feel or if Ill be home etc. Because I know it will be dried when its done. Additionally it sends an alert to my phone when the load is complete so I know to change the load. I choose to leave the notice on my notification bar until I go change it so I dont forget it. While laundry and washing machines arent the most thrilling this machine has really improved my day to day life. Originally posted on lg.com

I saved for a while to pay for this washer/ dryer all in one unit. It didnt work it actually broke right after I received it. The part was on back order until April so LG did the right thing and allowed me to return it. I was very grateful Such a great company.

Happy washer 212 4/16/2021
The dual washer dryer is the new love of my life. I havent had a personal washer in years. I always had to lug my clothing to the laundry. That was always an ordeal. I remember when the dual washer dryer started appearing in the States. I was used to see them overseas and was curious about them. When they came to the states I was hesitant. I didnt think that it would work good. My friend recently purchased one and raved about it. I live in a small kitchen apartment. There was no way a washer and dryer would fit in my place. I went to see my friends washer dryer combo and decided to take the plunge. I love the look. At first it was difficult to figure out how to use to because it only came with instructions on how to use the washer. I had to use YouTube on how to use the dryer part. It took me 3 washes and hours of YouTube videos to figure out how to use the dryer but I did it. The machine is quite. The only time its a little loud is when its on high spin. My whites came out so bright even after being abused by public laundromats. I love the WiFi and how you can monitor it from your phone. I was in the park and could monitor how many minutes I had left in a cycle. Yes it does take a little longer for you clothes to dry than the traditional dryer but it does not skimp on how dry your clothes are. Most times I have to leave them in the dry for a few minutes so the can cool off so I can handle them. I also love the fact that you can choose to have your clothes go from wash to dry without taking them out the dryer. You can just press the dry button and it will go from was to dry without you even thinking about it. I would definitely recommend this washer dryer combo. Originally posted on lg.com

We bought this all in one unit thinking it would make laundry faster and using larger load size because of the size of the drum. Come to find out it takes an hour and a half sometimes just to wash them and 8-9 hours to dry it There is absolutely nothing wrong with my machine as it has the technology to tell me when something is wrong so if thats the case the whole unit is defective. Anyways this unit is trash. Yeah its nice you dont have to switch it over but the dry time is absolutely ridiculous and I cant even set the drier timer on any downloaded cycles so I have to wait for it to tell me its done washing to come turn the drier portion of it on so itll dry my clothes 8 hours later.... all in all this washer/drier unit is garbage and I wish I figured it out before the return by date was up... lesson learned and money wasted money Originally posted on lg.com

With a family of 4 that includes 2 working adults its wonderful not to have to worry about putting laundry from the washer to dryer. I love being able to check the status remotely but it would be even better if you could turn the machine on remotely and have it start a cycle that way think adding a second round of drying for towels or heating up pajamas to warm up with after taking the kids sledding Originally posted on lg.com

Its been a few months now. Pros: space saving no wet clothes sitting for hours in the washer when you forget to transfer. Looks pretty Cons: clothes come out so wrinkled. I read the spin cycle is too strong and just smashes clothes in place. You Cant use dryer sheets. And clothes dont smell very clean. Requires a lot of maintenance. You have to drain the water wipe the edges and rubber parts clean the filter. Its not a huge deal but more maintenance than I thought. I thought about returning but I am going to just try and figure out the settings to see if I can make it work. I would not buy again. Originally posted on lg.com

So we were told by sales associates at Home D and read other reviews saying that its not worth it it takes to long blah blah blah. So I was a little hesitant at first but went ahead and purchased the all in one washer dryer combo and was mind blown I was or am completely satisfied with the way this thing works. Im not sure why theres 1 bad review out there because this thing is awesome People complain about how long it takes its no longer than having to do it with a regular washer and dryer plus theres no taking out of one and putting in another. You literally set it and forget it. This machine saves so much room and is just absolutely amazing words dont do justice. Originally posted on lg.com
