Well, there's power to parts of the machine, so you need to figure out where you're losing it. Let's take the door switch for instance. There's three wires on the door switch. One wire is COMMON and is on the common terminal on the switch. The wire for the light is on the terminal marked NC or Normally Closed. That means power for the light can go from the COM to to the NC and the light is on. The wire for the start switch is on the terminal marked NO or Normally Open so power can't go to the start switch with the door open. Now we close the door. The part of the switch that was closed for the light, is now open, no light. and the part of the switch that was open, is now closed, power to start switch. Just because part of the switch is good (LIGHT) doesn't automatically mean the other part of the switch (START) is also good. Now do you get it?

Do any of the LED's on the control panel turn on? If not check all the wire connections and check for supply voltage at the control board. If the indicator lights do turn on check the door switch with an ohmmeter for continuity when the switch is pressed in.
