MDB4949SKZ 0 not pumping water into spray arms

Brand:
Model Number:
Main Symptom: Not pumping water
What happens & when: It starts, takes in water. I can hear a very feint beep when it trys to circulate the water. and then it just goes silent, almost like it is off, though the lights are still on.

Error Code (if any): none.
Parts or tests already tried: I replaced the water inlet valve, because it was not even taking in water. So that part has been fixed.

Almost forgot, i did open up the part of the circulation pump that can often get clogged, and it was clean. I am guessing that it is just a new circulation pump and motor assembly that I need? ( I think they come as one). not sure.

Markfox, this could be a failure in the main control, circulation pump, or even the wire harness. With the power supply off, if the outer door panel is removed and the console secured to the inner door panel with a screw at each corner, the main control can be tested for voltage to identify where the issue may be once power is turned back on. A cycle can be started and the two light blue wires at connection P5 pins 1 and 2 (see attached image for reference) tested for Volts AC. After the water valve stops filling, there should be 120 Volts AC when testing these wires. Does voltage appear or does it stay at 0 Volts AC?
