A breaker trips if there is a fault. There are two sorts of breaker - the RCD or the Micro Circuit Breaker.
When the RCD trips it suggests a fault that is allowing current to leak to ground.
When an MCB trips it indicates the appliance is trying to consume too much current.
Either way the only way to find the fault is by dismantling the appliance and checking the circuitry with a multimeter.

Andy, leave the breaker off and remove the toe panel (bottom panel) from the dishwasher. Remove the cover of the junction box where the cord connection or wiring is made. Look at the wire caps and see if they are not burnt. Sometimes these connections become loose and arch, tripping the breaker. If so, cut the wires, strip a new end and reconnect. Catriver...post back.

First off, be sure the pigtail is wired correctly to the back of the unit. Black and red to the outside terminals, white to the middle, green to the frame or cabinet (should be a green screw close-by). If that is ok, you probably have an issue with possibly a bad pigtail, bad outlet, wiring issue, or possibly a bad circuit breaker or breaker box. Probably going to be more of a electrical problem than a appliance problem. Good Luck!!!!

If your outside condenser has a locked rotor or short circuit, than the unit WILL trip the breaker - as it should. On the other hand if a breaker is tripped a few times it will have less of a capacity that the rating, (this is designed in it). You will need to determine if the unit is locked (and broken) or the breaker has become too sensitive.
SOURCE: Keeps tripping circuit breaker everytime on plug the power cord in
2 common, possible problems. 1 - there is a "short" in the plug - easy fix - replace either the cord or plug - not expensive. 2 - bad control board - not so easy, not so cheap. Is it brand new, used? Also, it could be a bad "internal breaker" - not easy!

It's possible that the first breaker that you said does not trip - it could be that breaker is failing to trip on a bad circuit. That is, it could be you have a bad circuit but that first breaker is not detecting it and pretends everything is OK. If your new breaker trips on the first breaker's circuit, the curcuit it probably bad and the breaker in not working properly. The most common problem for failed circuits is a stray ground wire in a box somewhere in the curcuit resting against a hot or neutral wire. You'll have to take apart every connection on that curcuit to find it. Not fun.
