cwa dishwasher tripping the electrics?

I had a machine with similar symptoms. Probably water is getting into the electrical wiring causing shorting out and tripping electric fuses/safety switches.
You could check by turning off and disconnecting power, then checking under machine near electrical wiring for water.
Two of many possible water sources are hose leaking onto electrical wiring/parts during filling, or water that overflowed during the drain blockage you mentioned.
