Frigidaire 1050REC0 won't start

SOURCE: my dishwasher shuts itself off

The lights will typically blink when the door comes open. It may be that when the washer warms up, parts of it expands and allows the door to open slightly. It may also be that the trigger that registers the door being shut is not being tripped.

It should still work pretty well but you probably can't use the high temp wash because it will take too long for the dishwasher to heat up the water enough to satisfy the high temp washer thermostat. If the thermostat's calibrated closing temperature isn't reached the dishwasher will just keep running. One thing you should do to improve washing results is to run the nearest tap (probably the kitchen sink) until the water is at it's hottest and then run the dishwasher so the first fill will be hot rather than warm.

This is very likely due to a bad main electronic control board but the only way to know for sure is to do some electrical testing with a volt/ohm meter and the wiring diagram located within the appliance. If possible use the meter and the wiring diagram to check input/output voltages looking for discrepancies between the diagram and the actual meter readings.
