Common Tankless Water Heater Issues We Repair
Tankless water heaters are an excellent choice for homeowners who want endless hot water, but like any system, they can develop issues. At Nolasco Plumbing, we handle a wide range of tankless water heater repair services. Here are some of the most common problems we repair:
No Hot Water
If your tankless water heater isn’t providing hot water, the issue could be due to a malfunctioning heating element, a blocked air supply, or a faulty gas valve. Our technicians will quickly identify the problem and get your system back up and running in no time.
Inconsistent Water Temperature
If you notice that your hot water temperature fluctuates, it could be caused by a variety of factors, such as a dirty filter, mineral buildup, or an issue with the thermostat. Our team will diagnose the issue and provide the necessary repairs to restore consistent water temperature.
Error Codes
Many tankless water heaters display error codes when something goes wrong. These codes can indicate a variety of issues, including electrical problems, gas supply issues, or water flow problems. Our plumbers are experts in reading and interpreting these error codes, and we can resolve the underlying problem efficiently.
Water Flow Problems
Low water flow is another common issue that can affect tankless systems. This could be due to clogged pipes, a malfunctioning flow sensor, or mineral buildup inside the unit. We’ll troubleshoot the system, clean out any blockages, and make the necessary repairs to restore proper water flow.
Mineral Buildup and Scale Accumulation
Hard water can lead to mineral buildup in your tankless water heater, which can cause the system to overheat or fail to heat water properly. Regular maintenance is key to preventing this issue, but if you’re already experiencing scale buildup, we can clean and descale your system to restore its efficiency.
