Could this be causing e035. Web hi, i keep getting an error message on my navien machine : I am sure some of you have expeirenced this. If this occurs, the boiler initiates shutdown. Check the wiring in the remote control; Check if the igniter is sparking. Wait 2 to 3 minutes and then plug it back in; How long has this been going on with your navien? The unit should be between 15 and 25psi if you are below 10 the unit will lockout. Just as before, you may be able to fix this yourself by adding water to the boiler, which in turn increases the pressure.
If the water pressure sensor senses low water level as the heating pipe pressure is low, the system stops operation of the boiler, and refills water automatically. I just discovered the issue. I am sure some of you have expeirenced this. Check the wiring in the remote control; Most commonly they get clogged or stop operating causing the boiler to get low on pressure. Reboot the system by unplugging your tankless. The following table or page contains the information required to help repair and diagnose the fault codes being shown on the boiler display. Check and ensure the water pressure sensor and wiring are in good working condition, and there are no loose connections. Just as before, you may be able to fix this yourself by adding water to the boiler, which in turn increases the pressure. You may be guided through the fault finding sequence or steps, for rectifying your boiler with this fault code. I called navien support and was told to read the psi after i plug out and in the system.
