Dishwasher trips breaker. Breaker only resets of door is opened

My ge dishwasher, only 6 yrs old, trips its breaker. The breaker will not reset unless the dishwasher door is opened. Then it will trip when door is closed. This started when i used the "antibacteria" cycle. ive used it before with no issues. Breaker is not the issue, as i switched it with another to be sure. Everything under the foot plate appears intact. House wires are intact. I did pull a rather long wire twist tie and a a small piece of rubber from the drain, however im not sure that could have been the problem.
