difficult to answer but could be a drain pump issue which may of blown something on the PCB or door lock or motor.Without testing it is hard to help you honestly.If you don't have test meter and some electrical knowledge it is going to cost you to get repaired.If it is PCB I would suggest buying a new one as they cost 50% plus of the cost of a new machine without some one fitting them for you and if a fault is still present after fitting the new one it will blow that one up Too!
