Tankless Water Heaters – What to Do When They Have a Problem

A tankless water heaters, just like any of the tank water heaters, is prone to wear & tear, damage & other malfunctions. It’s imperative to know how to respond when your tankless heater undergoes an issue so you can resolve it efficiently & effectively as soon as possible.

Issues in tankless heaters usually occur due to the buildup of waste, poor maintenance, or environmental factors. These obstacles can reduce water quality, lower water pressure & make it harder to access hot water when you need it. Take a look at some of the issues that can affect your tankless water heater & what you can do about it:

Signs Your Tankless Water Heater Has An Issue


First of all, it’s important to be aware that many problems occur gradually over time rather than all at once. Instead of recognizing immediate signs of issues with your heater, you might find only a few minor symptoms of problems that will eventually get worse if not treated. These symptoms may include the following:

  • The water changes visibly, looking cloudy, rusty, or like it has small chunks of material or sediment in it.
  • Strange noises are coming from the heater & pipes, such as banging & rumbling.
  • The water smells & tastes metallic or otherwise strange, indicating the presence of iron or rust.
  • The heater cannot maintain a consistent standard of water pressure or temperature & testing the valves & settings makes no difference.
  • The digital display is showing an error code.

If any of these symptoms are observed, it could signal mineral buildup, pipe issues, system breakdown, or other problems. These symptoms are enough to warrant a closer look by any of Proficient Plumbing Solutions’ experienced professionals.

Why Should You Act Quickly

Failure to act quickly on the symptoms noticed above could lead to a loss of hot water & more expensive repairs. You could ignore the early symptoms of a much deeper problem that will become more costly & more damaging to your investment’s overall life expectancy. Even if the causes of these symptoms are not significantly damaging, they could at the very least cause your system to become less efficient &, thus, more costly to run.

Next Steps You Should Take

You can conduct a little troubleshooting on your own before calling. Here are four steps you can take to better understand the causes of tankless water heaters issues:

#1. Call the local water plant:

If there have been water quality changes, it may not be relegated to your property alone. Call your local water plant & ask them if there have been any changes you should be aware of.

#2. Pick up a water testing kit

These kits will allow you to see whether there are any safety concerns with the water in your pipes & can help you see the iron level in the water. Contact us for more efficient testing of your water.

#3. Track your pressure & temperature

If your tankless water heater is inconsistent in how it provides water, you should keep track of the pressure & temperature over the next week. If the efficiency levels vary wildly over that time, there could be a severe problem with your heater. If the trend is more gradual, then it may be time for routine maintenance.

#4. Consult the manual

If your unit has a digital display showing a warning message or an error code, you may be able to figure out the problem yourself. Your unit should come with a manual you can cross-reference with the code. If you can’t find it, look on the manufacturer’s website. Depending on what the code means, you may be able to implement a solution yourself by following the manual instructions. If not, you should call a professional right away.
