Avice needed please! Purchased a secondhand Bosch Excell Dishwasher from someone at work - 18months old. Transported home in back of car - about 5 miles - watering was leaking out of it so not sure it was drained properly. The timer starts counting down but nothing else happens. Quick Rinse does nothing either. When I open it there is water right at the bottom. Is there anything I have done that would have brocken it?
