Pump not running to drain

My GE Profile Dishwasher PDW7800N00BB will not drain.
The pump works to circulate but it does not start and run to drain.:frowning:
It isn’t making ANY sound when it is supposed to kick in and start draining.
Is there a saftey interlock that stops the pump from starting if there is a drainage clog?
If it is not clogged, what needs to be checked?
