Samsung Front Load Washer model WF45K6500AV/A2  with 4C error code. All solenoids work properly and fill when in diagnostic mode, valves get 120V. When you put the washer in normal mode it tries to fill but I am only getting 107 Volts at the solenoids which is not enough to activate them. What can be causing the unit to provide incorrect voltage in normal mode. Changed the Main PCB and had same results.

@Caleb Willey  It amazes me how deep and complex this Appliantology can go. 

I would think 107 volts sufficient to open the valves. Are you using Lo z ?

You say you've  replaced the board. I'd probably be eating that board myself in you shoes.

I'd love to hear what others might think about this myself.

Really and truly at this point I'm playing parts changing monkey and throwing this at it.

Part number: DC93-00278A

@Caleb Willey Man you're not getting no love.

Was 4c the only error code you had? 

I've heard it said  "test manual operate the loads mode the board is bypassing the peripherals.

So what sensors have anything to do with signaling the board to turn the water on? Water Level Switch?

Temp thermistors maybe? 

I don't know how to troubleshoot MEMS?  I understand  it to be a vibration / out of balance sensor. I have no idea how that thing works. It's a technological marvel as far as I can tell. From my  experience that little vibration sensor (mems) is playing more of a role than just sensing out of balance loads. Twice on top loads now, that same little MEMS sensor I found to be playing a role within the water valve circuitry. Broken wires between the MEMS and the Main Control will play tricks on the water valve circuitry as well.
