Frigidaire Gallery Dishwasher - lights flash, won't run cycle?

I have a Frigidaire Gallery Series (Model#GLD2450RDB0). All four LED lights (Sanitized, Washing, Clean, Sensing) flash and the "Hi-Temp" and "Sanitize" buttons flash as well. If I flip the breaker, it seems to do a service/water test when the power comes back (counting up from 1 to 8). Then it will seem to start a normal wash, get a couple minitues into it and then flash "00" and the "Sanitize" and "Hi-Temp" buttons light up. And then it seems to cycle into the service/water test pattern. Any ideas? Thanks for your help...
