Why does this error occur? It might be due to defective ignition parts like the flame rod or ignition transformer. Alternatively, it might be a result of insufficient gas pressure or the existence of air in the gas line. Sometimes, the gas can be turned off or the unit is not properly grounded.

How to Fix Navien Error Code e003

Don’t bush around; if you see the Navien e003 error, swift action is required. Here is a step-by-step guide on how you can fix the problem.

Step 2: If the issue persists, inspect the system for any gas leaks. In case you find one, turn off the gas supply immediately and contact a technician to fix the leak.

Step 3: If there are no gas leaks, the next step is to check the gas pressure. Low gas pressure can prevent the heater from igniting. A professional technician should execute this step since it requires specialized equipment.
