What people are saying

Rated 5 out of 5 by from Just Right When There is Nowhere to Vent 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.

Rated 5 out of 5 by from Awesome! 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. I’ve 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, I’m using less water, less power, less detergent and cleaner clothes!

Rated 5 out of 5 by from Impressive Performance 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 ½ 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 ½ full it’s 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 isn't perfect, but running a load of laundry that I plan to air dry washes most of it away. I’m hoping to find a better solution for this soon.

It does not appear this product is energy star rated.  Can you provide the approximate energy use kWh per wash and dry cycle?  What is the maximum power draw in kW?

Asked by: Shanedogg

At the end of a cycle, is the machine dry so you do not have to leave the door open to allow rubber seals, etc to dry?  Is there ever a point in operation that you should leave the door open?
