Hi - my Bosch s9j1b dishwasher will not run. I've reset it so that the end light, 2 curved arrows light and the 50 degree light is on. Closed the door and it makes the usual noises but no water seems to flow. If I open it then end light remains on. My wife thought that she had seen the tap light on but I can't recreate that. I've cleaned out the filters etc and everything there seems fine. Any thoughts on what I can do next? Thanks
