New WP Washer and Dryer
About the only thing really new to these machines is the touch electronic control that does away with the troublesome membrane controls that Malcolm mentioned.
The nut looking thing in the middle of the dryer bulkhead is just a spray port that a fine mist of water comes out of for the steam feature, WP-KM has had this feature for about 10 years now.
WP builds dryers with three different style blowers, direct drive with the blower wheel mounted directly on the front or rear of the motor, this dryer has the blower on the front of the motor.
On some of their bigger dryers they either use a belt driven blower like Brent posted in reply # 22, on higher end models the blower has its own variable speed motor eliminating the belt. We have not seen many problems with these new systems, but they are more complicated and will be prone to some problems that you would not have with the blower mounted directly on the motor.
The excessive lint build-up pictured in reply#22-2 is typical of a dryer that is not vented properly [ or at all LOL ]. The pictured build-up has NOTHING to do with the design of this dryer, I have seen every dryer design imaginable is as bad a condition in my career. The picture Brent shows has also been doctored if you look at the duct at the bottom of the lint filter housing, you can see they stuffed hand fulls of lint in it before the picture was taken, lint would never built-up in clumps like that. For a dryer to be in this condition the area around the dryer would also about the same.
