Hello,
I used the above answer to try and get my rainwave 1100 to use the dryer function, two years and i only just figured it out! i used to use the "fast spin" which is under the letter C on the dial and thought that was the same thing, but using the above advise i put it on fast spin "C" and set the 1/2 load option next to the power on/off button and it started working! so just set the dial to letter C "fast Spin" and set the 1/2 load option and give it an hour or so, it will get to the end of the cycle after doing the fast spin and then turn to the dryer function (after heating up).
