Samsung Front Load Washer Which Board Controls Drain Pump

[gaspower]

Hello,

I have a Samsung WF438AAR/XAA Front Load Washer. Can someone please let me know which board actually controls the drain pump. Looks as there are two boards, the main board and the inverter board. I have tested everything else to diagnose why it will not drain, and all pumps work, so it must be the board.

Thank you JR

The wire diagram don't break it down well, looks like the main board:

There's 120v going to the pump based on that diagram, so main board.
