That is error code 31, it is caused by the pressure switch not closing due to many possible reasons.

Part looks like this picture link.

It senses when power venter exhaust fan starts.

Ok, options are...

blocked vent pipe

blocked drain (if equipped)

cracked rubber tube to switch (works off suction not pressure)

Nipple ports where tube attach blocked.

Bad pressure switch.
