And there is no water going into the machine, checked all the
obvious connections,

Check the float valve..its a cylindrical, usually white, plastic knob about
3" in diameter on the bottom of the inside compartment. When the washer
fills with water, it floats up and shuts the water off. One of the D/W I
installed had a sticking valve and , initially, no water would flow in. I
gave it a tap and it dropped down and away it went.
