How can you tell if your flow sensor is causing your Navien tankless water heater not to heat? Well, there are a few telltale signs. If you’re not getting any hot water at all, despite the heater being on, it’s likely a flow sensor issue. Alternatively, if you notice that the water temperature fluctuates excessively or the heater turns on and off intermittently, this can also indicate a faulty flow sensor.
Troubleshooting Flow Sensor Issues
If you suspect that the flow sensor is the culprit, there are a few troubleshooting steps you can take. First, check for any obstructions around the sensor and clean them if necessary. If that doesn’t solve the issue, you may need to call a professional to inspect and potentially replace the flow sensor.
Preventive Maintenance
To reduce the likelihood of flow sensor problems, it’s important to schedule regular maintenance for your Navien tankless water heater. This can help ensure that the flow sensor remains clean and free from debris. Additionally, keeping an eye on your water quality and using a water softener system can help minimize the build-up of mineral deposits.
In conclusion, if you’re facing issues with your Navien tankless water heater not heating, it’s worth checking the flow sensor. This essential component plays a crucial role in detecting water flow and initiating the heating process. By understanding the common problems associated with flow sensors and following preventive maintenance measures, you can keep your tankless water heater running smoothly and enjoy a reliable supply of consistent hot water.
