When youn push button to start it says F1 what does that mean ??

Before you waste a penny. over the years i usually get an F1 code, this time i got an F40. what happens is the vibration from the dryer loosens the connectors on the pane.l twice I've had repairman here under a home warranty plan usually when the washer acts up because it doesn't cost extra to have them check both. twice they changed the control box which probably costs the warranty company a lot of money. unplug the dryer. loosen the three screws in the back that hold the control panel cover on the top of the machine. pull forward and take it off and lay it on the machine, the wires are long enough. pull off and reset the connectors pushing them in tightly, particularly the ones on the left control module. the right one is probably fine, its usually the left one. plug the machine back in and test. if that don't work try the right panel plugs. now, these are the modules on the top of the machine, i have never touched anything in the cover you take off. it will probably be fine until they get loose again. maybe one month, maybe six months maybe never. i'm not a repairman, just a Do it yourselfer

The F01 error code indicates a primary control failure and more than likely the machine control (p/n W10174746) will need to be replaced. Parts can be purchased from Sears PartsDirect.
