    navien keeps shutting down error e002 low pressure on heating side , Installer says caused by leaky pressure relief valve that he will come back and replace and bleed system , after holidays. Unfortunatley its not restarting now and its Christmas morning. Can I trick the system into start up somehow thru programming and shuting off the heating side so I can have hotwater until he gets back off holidays. And have a SHOWER!

    Sorry to hear about your issue, I have had nothing but bad luck with Navien tankless heaters and refuse to install them...

    Tricks end up bypassing built in safety devices and could create an unsafe condition for you and your family so I can make no recommendations except to have a licensed and certified tech address your issue.

      Thats because your installer is an idiot and failed to connect the auto feed port with a cold water line. Unit is attempting to fill and cant, thus it shuts down due to lack of water as it should to protect itself and you.
