The drying cycle pulls the most current. On most units there is a heating element in the bottom of the machine just like a stove has. Bosch does not use this technique, they have a built in heater in the water system that superheats the wash water. IT may be that nothing is wrong with your machine. When the unit was installed, there are wire nuts that are put on the supply wires in that unit and if they are not installed well, they can have an issue with overheating when the machine starts using a lot of current.
Testimonial: "In fact the wire nut melted and burned. I'll try a better connection and hope I'm not just moving the smoke point somewhere else!"
The dish washer must have a drying cycle and the heating element has a short circuit somewhere.

the first thing that works is the drain pump at beginning of cycle check pump for blockage, if ok check voltage to pump , if you do not understand this answer leave well alone.

Bill that is exactly what happened, the connection wasn't correct from the start. The Bosch dishwasher pulls 11 amps during the cycle while heating the water to temp. The cooler the water the longer the heat time. Your dishwasher came with a set of wire nuts that where suppose to be used. Be sure when you correct this to use 20 amp wire nuts with the unit. This will stop this from happening again.

It doesn't work at all
If your dishwasher doesn't work at all, check these:
Power from the house
Is there power getting to the dishwasher? This can be difficult to test, because dishwashers are usually wired directly to an electrical circuit, rather than plugged into the wall. But at least check for a blown fuse or a tripped circuit breaker.
Door switch
The door switch is important because, if it's defective, the dishwasher won't work at all. To reach it, you need to remove the control panel cover, or sometimes the interior liner of the door. If it's defective, you need to completely replace it.
Wiring
Often the main wiring connection from the house, at the dishwasher, burns and breaks the connection. If that's the problem, the wires must be repaired/replaced as necessary. If that's not the problem, check the wiring to the door switch, the wiring between the door and the lower part of the dishwasher, and the wiring to the timer. Repair any broken, burned, brittle, or defective wiring, using the proper appliance-grade wire and connectors.
Timer or selector switch
Although it's uncommon, the timer or the selector switch may be defective. If so, you need to replace the defective part, because neither of these can be repaired.
