I replaced the water inlet valve (prior to purchasing a multimeter) which didn’t fix the problem.
After testing with the meter, the switch is not getting 120V and I’ve learned the the “control board” is likely shot. My problem is… AppliancePartsPros offeres more than one “board” on their parts list for the PLD2850RDC0. Which board do I need to replace? This question means the difference between spendiing $50 or $180.
Can someone please clarify this?

You did not mention it but have you checked across the water valve/overfill switch combo for voltage. If the switch is toast or the float stuck in the up position you will not get voltage to the water valve.
