My 4 year old cabrio dryer (Model# wed6200sw1) won't start either. Once the start button is pressed, the sensing light indicator comes on and nothing else happens. No "codes" are shown. Power is coming to the unit, but it doesn't "dry" at all. The lint trap and exhaust vents are both cleaned and clear. I've previously had a service technician out to repair the machine when the "AF" code was indicated.
