The Water Pressure Sensor on Your Navien Boiler

The water pressure sensor (transducer) tells the boiler the system pressure so it can lock out safely on low pressure and display fill prompts. A drifting sensor causes false low-pressure faults even when pressure is fine.

On Navien systems — including models such as NCB-240E, NCB-210E, NHB-150 — a failing water pressure sensor often shows up as e003 ignition failure or related symptoms. We diagnose it precisely and install the correct genuine Navien part.
