Not washing

my dishwasher is not washing, the steam comes on, but no water is being sprayed, the water supply line was checked and cleaned, the soap in the dispenser is not desolving what can be wrong?:mad:

Here is the parts breakdown.

I am assuming that the unit is filling with water.
Also assuming that you do not hear anything.

It sounds like the main pump is not coming on.
Check that it is getting 120 volts when it should.
If it is and it is not rotating or making any noise then the pump is likely toast.
