3/11 Common Causes of Error Code E003

The enigmatic and elusive Error Code E003, lurking within the depths of Navien Tankless Water Heaters, possesses the power to disrupt the harmonious flow of hot water. Its origins are varied and mysterious, stemming from the realms of a faulty igniter electrode, electrical quandaries, or a malfunctioning PCB. However, fear not, for there exists a solution.

The key lies in the realm of regular maintenance and inspection, a sacred ritual that safeguards against this formidable error and restores tranquility to the realm of heated water.

4/11 Checking the Igniter

Ensuring the optimal performance of your Navien Tankless Water Heater requires regular maintenance of the igniter. This vital component ignites the gas and kickstarts the heating process. By routinely inspecting the igniter, you can detect any signs of wear or damage early on, preventing potential complications.

One possible indication of a worn or damaged igniter is a weak or inconsistent flame. If you notice that the flame isn’t as robust as before or frequently extinguishes, it may point to an issue with the igniter. Additionally, if you hear a clicking sound but the heater fails to ignite, this could also be a red flag for an igniter problem.

To troubleshoot igniter issues, start by cleaning it and removing any debris or buildup that may be obstructing its functionality. Take care to brush off any dirt or dust from the igniter electrode. If cleaning doesn’t resolve the problem, it may be necessary to replace the igniter.

When dealing with igniter problems, always refer to the manufacturer’s instructions or seek professional assistance. Attempting to fix the issue without proper knowledge can potentially cause further damage or compromise safety. By regularly monitoring and addressing igniter issues, you can ensure that your Navien Tankless Water Heater continues to provide a reliable and efficient supply of hot water.

Did you know that Navien tankless water heaters are not only energy-efficient, but they also have a built-in recirculation system that eliminates the need for a separate pump?

If necessary, troubleshooting steps may include cleaning or replacing the electrode to restore its functionality. Equally important is the examination of the PCB for any faults or malfunctions.

Keep an eye out for error codes, inconsistent heating, or system failures.
