[Electronics_101] How to test contactor coil

 

How would I test the coil within this contact?

Also, with a multimeter should I also be able to tell what voltage the coil is?

Also, I am assuming that when power flows thru the coil that creates the mechanical energy to cause the contacts to touch.

I know am no longer able to get any part of the pressure washer to work. Previously the water pump would work but not the heating unit. Know I can not get any functionality via the swith.

When I manually push down on the contactor switch the water pump does work, but not the heating unit.

Below is a photograph
