What people are saying

Rated 4 out of 5 by from Greatest purchase ever My clothes have never been cleaner and never been so convenient to wash clothes. If you purchase this machine there are some things you must be willing to give up for the convenience of one machine. After each load you need to clean the lint that sticks to the door and seal. The drying cycle takes 2-3 hours to run. The clothes might feel damp when removing them from the dryer while hot but they’re not. They are just warm and the feeling of damp goes away as they cool.

Rated 5 out of 5 by from Washer and dryer I am so happy and satisfied with my washer and dryer. Hope Depot was very firm in helping choose the right one at that! Thank you for all you do.

Rated 1 out of 5 by from DO NOT BUY!!!!!!!!!!!!!!!!!!!!!!!!!! I was beyond excited to buy a washer dryer combo but since having it installed it has caused me nothing but a headache. We are a family of 5 and this machine is not suitable for a family that size. Your clothes do not come out fresh and clean feeling, blue jeans come out completely wrinkled like they have been sitting at the bottom of your dirty clothes basket and some shirts do too. I do not over fill the drum! I also have to wear scrubs in my career and they come out looking like I have just rolled around in lint. The top of the dryer gets extremely hot to the touch. Now only having it hooked up 3-4 months it will not drain water. I NEVER had this problem or any problem with my old washing machine but it was just time to update. Now I'm stuck with this machine that is completely useless because I gave my other one away. Just trying to save someone the headache we are currently going through.

My clothes are really wrinkled after drying, I have tried doing small loads and trying to take them out right after the machine finishes the dry cycle but it is too hot, is there a setting to just tumble dry clothes after the drying cycle?

Asked by: Twee
Press the “Power” button!  Load wet clothes!  Press “Dry” button and close  dryer door!  Dryer button is best in normal position!  Dryer will sense approximate time!  Place Spin Speed to “No Spin” position and activate with >|| button!  Machine will highlight drying time in digital display!

Can you use dryer balls with this combo?

Asked by: j1234n
Dryer balls come in a variety of materials and sizes. The most popular type of dryer balls are wool dryer balls, but there are also plastic variants and rubber variants. The theory behind how wool dryer balls work is that they help prevent laundry from clumping in the dryer. The balls also retain the heat they receive on the dryer and boost the drying process. This way, laundry dries more efficiently and faster, thus reducing drying times in your load of laundry. Additionally, wool dryer balls help to soften fabrics when used in the dryer. The balls continually agitate against the fibers in clothes and linens. So, after a (shorter) drying cycle, your clothes would also be soft to the touch. When used properly, dryer balls can even take care of static cling. For them to work properly, they need space; they need room. This means that wool dryer balls work more efficiently with medium to small-sized loads. They can be thrown into the tub with your clothes in the LG Front Load Washer / Dryer Combo, Model # WM3997HWA during the drying cycle. Be sure to follow the manufacturer's directions for their use...^IFV
