My Bush/Baumatic Dishwasher gives an E1 error, originally it had an E4 error, this was a leak in the sump seal. I have fixed that but, now I get an E1 error. I have checked the inlet hose and filter. I tried different settings of the stopcock. When turned on the pump runs, then the machine fills, I then get an E1 error and the machine bleeps and then empties.
