Runs with door open

Dishwasher is stuck in drain cycle and still runs when you open the door. Tried to reset by turning off the breaker, no luck. Off and on switch works, where do I start?

The first thing I would check is the door switch (#3 on the break down diagram).

Here are the break down diagrams for the Bosch dishwasher Model SHV6803 UC/12 (FD 8105 -)
