Replaced pressure switch bc of F35 & now getting F20 error!

Hello, thanks to this forum, I was able to troubleshoot a F35 error with my Whirlpool duet steamer washing machine. I THINK the issue is related to the pressure switch and just received the new switch. I replaced it and tried running through the diagnostics but now I’m getting the F20 error. Is this a sign that the control board needs to be replaced? Or do I have to do anything to reset the pressure switch before using it?
