The clean light is flashing and this happened to me when I first bought it. Could anyone please tell me the reset code for model # 665.17053402? My husband works around the country most of the year and I have to take care of all the maintanence problems not only for my own home but my 3 unit rental as well. I had a repair man come when I first bought it n I hate to accuse w/o knowing for sure but, found things missing a few hours after he was gone? So I prefer to do things myself unless I have a friend that specializes in what ever I need fixed. Could someone PLEASE, PLEASE, PLEASE, help me?!
