Dishwasher won't start

Dishwasher won’t start. Ran it yesterday and it stoped working before comple end of cycle and left water standing in bottom of d/w. Now it won’t start at all. I have checked the door latch switches and they are ok ( they both show continuity with ohm meter). Now I don’t know what to do. Please help.

Here are your parts, includes a wiring diagram

Check to see if the unit is getting power.
If it is connected with wire nuts check that they are both OK.

Have to checked that the latch is actually closing the switches?
