I have a Miele Built-In

Check to see if the water shut-off valve (located under the sink, it is an electromagnet valve, located at the pipe's entrance to the machine) is open. If you get water to the dishwasher, but there is still no water inside during the fill cycle, the problem might be with a faulty water valve (located at the bottom of the dishwasher, behind the kick panel, on either side), in which case replace the water valve.
