Tankless Water Heater Repair
Tankless water heater repair should be performed by a licensed plumber. Tankless water heaters are complex appliances with gas or electric components that can be dangerous if handled incorrectly. If you’re having problems with your tankless water heater, it’s best to call us to diagnose and repair the issue.
Common tankless repair issues
Ignition problems
A faulty ignitor or gas control valve can prevent the heater from igniting properly, leading to no hot water.
Flow sensor issues
A clogged or malfunctioning flow sensor can stop the heater from activating when it detects water flow.
Overheating
Mineral buildup or a faulty temperature control can cause the heater to overheat and shut down as a safety precaution.
Leaks
Leaks can develop around the connections, pressure relief valve, or heat exchanger.
Signs your tankless heater needs repair
No hot water
This is the most obvious sign that something is wrong. If your tankless water heater isn’t producing hot water, it could be due to a number of issues, such as a faulty igniter, a clogged heat exchanger, or a low water flow.
Leaking water
If you see water leaking from your tankless water heater, it’s important to call a professional right away. A leak could indicate a serious problem, such as a cracked heat exchanger or a faulty pressure relief valve.
Strange noises
If your tankless water heater is making strange noises, such as banging, gurgling, or hissing, it could be a sign of a problem. Don’t ignore these noises, as they could indicate a potential safety hazard.
Error codes
Many tankless water heaters have LED displays that show error codes when there’s a problem. If you see an error code, you can look it up in the owner’s manual to see what it means. However, it’s still best to call a professional to diagnose and repair the issue.
Troubleshooting tips
- Check the error code: Most tankless water heaters have a digital display that shows error codes when a problem occurs. The manual will usually have a list of error codes and their meanings.
- Inspect the water inlet and outlet: Make sure there are no clogs or kinks in the hoses.
- Check the gas pressure: If the heater is gas-powered, make sure the gas pressure is within the correct range.
When to call a tankless plumber
- If you’re not comfortable troubleshooting the problem yourself.
- If the problem is complex or requires special tools or parts.
- If the heater is still under warranty.
Additional things to keep in mind
- Tankless water heaters are more complex than traditional tank heaters, so repairs can be more expensive.
- It’s important to hire a qualified tankless repair plumber who is experienced in repairing tankless water heaters.
- Regular maintenance can help prevent problems and extend the life of your tankless water heater.
