Our Bosch dish-washing machine (SGS 6902EU/07) is no longer filling in with water, displaying "F" on the led panel. Opening the side panel I see that no water is flowing in from the water mains. The dishwasher is using an Aquastop 's main water inlet valve: this is located at the water mains location, rather than inside the dishwasher.
To determine whether the problem is associated with the inlet valve or with the dishwasher, I measured the voltage across the inlet valve's terminals and it was 0V. I then considered the possibility that the inlet valve was short circuited, so I also measured the voltage with one terminal disconnected. The the dishwasher was turned on, this rose to 2.4V DC. I think this is too low; a manufacturer of such valves gives a 12-220V range in its specifications.
Any idea on what the voltage should actually be? Any suggestions for testing the valve?
