Product review (3 stars): Good Appliance with a MAJOR flaw
This appliance is generally good. But it has a huge design flaw.

We first installed this appliance with the drain hose placed in a wall drain. It took 5 hours to dry a small load of clothes. Some items like socks never dried completely. Before purchasing, I knew this appliance would take longer than a traditional dryer, but 5 hours was ridiculous. Figuring that something had to be wrong, I began to investigate.

As many other reviews have noted, the drains position relative to the appliance is critical. This machine uses cold water to dry the clothes  essentially cool tap water chills some pipes that act as a condenser to capture humidity from the hot air circulating through the clothing (like a dehumidifier). This tap water, along with the actual humidity extracted from the clothes, needs to be drained.  For some reason the pump is unable to move the water vertically to a wall drain (about 3 1/2ft above the floor) during dry cycle. I suspect it is because the pump is not fully primped like it is during wash cycle. Instead of pumping up into the wall, the water probably backflows into the machine and keeps the clothes wet, increasing humidity and lengthening dry time.  Other reviewers have noted that placing the machine higher on a pedestal improves draining as gravity assists the flow of drain water.

I can also confirm this is the case. We washed and dried several identical loads of clothing using the exact same wash and dry settings. For some of the loads we used the standard wall drain 3 1/2 ft. above the floor. For other loads, we put the drain hose into a 5 gallon bucket on the floor. The loads that used the wall drain took more than 5 hours to dry  some items longer. The loads that drained into a bucket on the floor (gravity-assisted draining) were dry exactly as the machine predicated using normal dry, usually in 1-2 hours.

Even though the user manual shows that the hose can be drain into a wall drain, it doesnt work.  The location of the drain relative to the hose is critical. If you have a floor drain, this machine will work well. If you have a wall drain, the dryer will take forever to dry and youll have to add dry time to each load. I suspect that there is either A.) A design flaw in the pump that affects all of these machines, or B.) A wide-spread defect affect a lot of these machines. Either way, it is very disappointing for a rather expensive appliance.

Fortunately in our situation, there is a crawlspace under the floor where I was able to cut a hole and install a floor drain that ties into the drainage system. If you are going to buy this machine, either (A) buy a pedestal, or (B) install/use a floor drain.

Now that it drains properly, I am generally satisfied with this appliance.
