Josh for Model Number MHWZ600WR00 I had the dreaded F21 error code display so I of course replaced the drain pump to get it again (the code) so I took out the hose with the ball, in so doing I disconnested the trap breather tube(?). Now I am getting an F-20 code..so my question is this: Does the tube connected to the pressure switch also connect to the top end of the trap which is connected to the hose on bottom of tub with ball in it?
