our dryer is flashing error code F01. model WGD8300SW2. ser. # MW3214079

The F01 error is an internal failure of the main control board. The only thing you can do is try and reset the electronics by killing power to it at the breaker/fuse panel on your home for one full minute then restore power. If after that the problem persists the control board will need to be replaced unfortunatley. The board you need for that model can be ordered from the link below.
