Dadgum drawers in my previous Whirlpool risers were removable.  That made it possible to adjust the height of the risers from inside the pedestals and leveling out both the washer and drier were easy.  BUT,  Electorlux design engineers took the cheap route.  The drawers in these pedestals are not removable and to get both the washer and drier to the same height requires a return service call where both appliances will have to be moved to a level area, placed side by side, leveled out, and then placed back in the laundry room.  Now, if the installers had been experienced, on the ball, and paying attention to such details, this would not be necessary.  HOWEVER, good help is hard to find these days.  OF COURSE, IF THE DADGUM DRAWERS WERE REMOVABLE, THEN I COULD LEVEL BOTH APPLIANCES!
