does the green start LED flash continuously or does it flash intermittently.count the number of flashes between pauses,eg five flashes then a pause and so on.the number of flashes can then be associated with a error code .this will narrow the fault down.at the moment iam thinking blockage,have you cleaned the sump filter and checked the wash arms for blockages(food debris )without the code it is impossible to say.I will add that if the start LED is flashing constantly this is a sign of main circulation pump failure or faulty pcb/.
