Troubleshooting Error Codes on Pasadena Tankless Water Heaters

Error codes play a critical role in maintaining the performance of your tankless water heater. Recognizing these signals can save you both time and money. Homeowners in Pasadena rely on the convenience and efficiency of these systems, and understanding how to troubleshoot can ensure they continue to enjoy uninterrupted hot water. Let’s explore the most common error codes you’ll encounter and the potential causes behind them.

Common Tankless Water Heater Error Codes

Tankless water heaters are designed to be efficient and reliable, but like any appliance, they can experience hiccups. Understanding the error codes that your tankless water heater might display can help you act promptly. Here are some of the most frequent error codes seen on tankless water heaters in Pasadena and what they typically signify:

1. Error Code 10: This code usually indicates an issue with the air supply or exhaust blockage. Causes might include blocked vents or restricted airflow.

2. Error Code 11: This one points towards an ignition failure. It could be due to a lack of gas supply or an issue with the igniter itself.

3. Error Code 12: This code suggests a flame failure. Potential causes are often related to poor gas supply or problems with the gas valve.

4. Error Code 99: This rare code indicates a combustion abnormality, which might involve issues in the combustion chamber or gas pressure irregularities.

Knowing these common error codes equips you with the knowledge to take swift action. The goal is not to troubleshoot everything on your own but to recognize when something isn’t right. Often, these errors may require more specialized intervention than what can be addressed with a DIY approach, but understanding the basics will empower you to describe the issues more accurately to our technicians.

Troubleshooting Steps for Common Error Codes

Addressing tankless water heater error codes swiftly can prevent minor glitches from escalating into major repairs. Each code has its specific troubleshooting steps that can help in resolving the issue.
