In all honesty if it flashed you can more or less say the board will of failed.might well be a faulty door lock which has blown the main pcb when it tried to start and lock the door.this is a common issue and very expensive.expect to end up with a £200 bill if you do call someone in and to be honest a lot of people/repairers will not be able to mend this type of fault so be warned!!!
