Hotpoint CTD80 Serial No.802080193?

We have a Hotpoint CTD80 condenser dryer. Nothing works or lights up, yet when tested I have 230 volts. The heater element was damaged and I have replaced the same, but still no sign of working or lighting up. Is there any way I can check the PCB before shelling out for a new one, or could there be any other problems stopping the dryer from working?
Regards Eddie
