Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now. Please give me time to respond sometimes I get your replies late so there may be a delay in my response.

That means the pressure switch did not open. Most times when that happens the pressure switch is bad. Check the pressure switch and remove one wire to it and see if the unit will start up without that code if so replace the pressure switch. Also remove the rubber tube and check the tube and ports to the pressure switch for blockages.
