Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

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.

The Future of LaundryJust Check the Box Content

Duck7_08 7/1/2026

I have been extremely impressed with the LG SIGNATURE WashCombo. Coming from a traditional washer and dryer I wasnt sure what to expect but this machine has exceeded my expectations. The first thing that stood out to me was the capacity. For an all-in-one washer and dryer I was pleasantly surprised by how much it holds. It easily handles our everyday family laundry and I appreciate not having to sacrifice capacity just because its a combo unit. I have also been very impressed with the built-in heat pump drying system. I was initially skeptical that a ventless dryer could perform as well as a traditional dryer but the clothes come out dry soft and ready to wear without having to transfer them between machines. Being able to load the washer press Start and come back later to clean dry clothes is exactly the convenience I was looking for. Another pleasant surprise has been how quiet the machine is. Ours is installed in our laundry room and I have not noticed any excessive vibration or noise during the wash or dry cycles. Its much quieter than I expected for an all-in-one unit. I also havent experienced any moisture issues after a cycle finishes. As a good habit I usually leave the door slightly open after unloading the clothes to allow the drum to air out but I havent noticed excessive moisture or dampness inside the machine. The AI Wash Dry cycle and the ezDispense system make laundry almost effortless. Once everything is set up the machine automatically dispenses detergent and completes the entire wash and dry process without any intervention. The only reason Im giving it four stars instead of five is because my unit was missing three accessories that are listed as included with the product: the dryer sheet ball Pet Care Dryer Ball the mesh laundry bag and the cleaning brush. While this doesnt affect the machines performance it was disappointing to discover those items were not included with such a premium appliance. Overall I am very happy with the WashCombo and believe it represents the future of home laundry. Aside from the missing accessories it has been an outstanding addition to our home and I look forward to enjoying it for many years.

Laundry made easy

Gallina41 6/23/2026

This machine has worked great. I was hesitant to get something that is ventless and runs on a standard plug but everything is dried and hot when it comes out. While it may take a little longer total time not having to remember to move the clothes from the washer and dryer gets us to take care of them quicker. Just set it and forget it and come back to clean clothes.
