My Dishwasher is a Blomberg DWT 25200 SSWS. It had the same problem. It powers up but no water enters in it and the clock didn't advance. This is what I did to fix it. You can display the error code by powering off the dishwasher then pressing the 'Program' and 'Half Load' buttons at the same time then power on the dishwasher. This will show an error on the screen. My error was E:1. The problem was a disconnected blue hose at the bottom of it.
This is the overflow detector.
This little board has a 12 Volt relay that activates the main water valve which is a 120 VAC valve. There was nothing wrong with it.
This plate is at the bottom of the dishwasher to hold the water that spills.
