Dishwasher not working after replacement top rack

I replaced my top rack for dishwasher and replaced the plastic mount that came with new rack. Now dishwasher does not start.
Dishwasher is GE MODEL GDF510PSR3SS. SERIAL GT888602B.
Part # AP8053826 (WD28X35779)

dishwasher is on but does not start. Feel like connection with the new mount is not good?

If the unit is not starting, this would not have anything to do with the installation of the rack. With the unit not starting, you would want to start by checking the door latch assembly to ensure that it is making good contact with the door strike.

It turns on briefly runs water then stops.

Check for a flashing light on the control board and see what the pattern is. Then, check the tech sheet to see what the flashing represents.
