What people are saying

Rated 4 out of 5 by from Great for small spaces Pros 1 cycle for the whole laundry cons can't stop it in between the loads to take out certain items

Rated 3 out of 5 by from I love this unit but... It takes a very long time to dry. After a year and a half of use there is a draining error.

Rated 4 out of 5 by from Very convenient Love that this fits conveniently in our 2 bedroom condo while leaving room for storage. Fits in a closet and very compact. Was skeptical of the 2 in 1 functionality but the dryer works pretty well. Just takes a bit longer. Still can't beat the convenience.

I'm curious about the WM3997HWA All-in-One. Although it is advertised to be "ventless", can it be vented. We're considering this for an install in Colorado and the space it will be located in will have a conventional dryer vent.

Asked by: David l 3
The W x H x D dimensions for the LG Front Load Washer / Dryer Combo, Model # WM3997HWA are 27” x 38 11/16” x 29 3/4”. To get it through a 25"opening means you will have to dismantle the cabinet on the unit.

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!
