Tankless Water Heater Repair: What You Need To Know

Tankless water heaters are one of the latest trends in the home improvement world. They’re popular for a myriad of reasons, but one of the main reasons is that they’re energy efficient. However, like all things, there are potential risks associated with tankless water heaters. In this blog post, we will explore some of the most common repairs and problems that can occur with these devices and how to fix them. By following these tips, you can keep your tankless water heater in good working order and avoid any costly repairs down the road.

When Should You call a Tankless Water Heater Repairman?

Tankless water heaters are a great choice for people who want to save energy and money on their heating bills. But like any appliance, they can sometimes go wrong. If you notice that your tankless water heater is not heating up or is making strange noises, it’s time to call a repairman. Here are some things you should know before calling a repairman:

1. Check the gas lines – The first thing you should do if your tankless water heater isn’t working is check the gas lines. There could be something blocking the flow of gas to the heater, which would cause it to stop working. If the lines are OK, check for any broken parts around the tankless water heater.

2. Check for broken pipes – Another common problem with tankless water heaters is broken pipes. If there’s a break in the pipe near the water heater, cold water may not be able to reach it and the system may not function properly. Broken pipes may also cause leaks and flooding in your home.

3. Test the hot and cold plugs – In order to test whether there’s a problem with your hot or cold plugs, unscrew one of them and see if the other one works correctly (or vice versa). If one of them doesn’t work, there’s likely an issue with that plug and you’ll need to have it replaced by a specialist.

4. Check for fuses – Sometimes problems with tankless water heaters can be caused by blown fuses. If you notice that your tankless water heater is not working and there are no broken parts around it, check to see if any of the fuses are blown. If they are, replace them with a specialist.

5. Check for thermostat problems – If your tankless water heater is not heating up or is making strange noises, it’s probably because the thermostat is not working correctly. This can be caused by a variety of things, including having the wrong type of thermostat or having an incorrect wiring connection. If you think your thermostat is the problem, take it to a specialist for repair.

What Else Might Go Wrong with Your Tankless Water Heater?

If you’re having problems with your tankless water heater, there are some things that you should know. First, it’s important to note that not all tankless water heaters are created equal. Some may be more likely to experience problems than others. Second, if you have a model that’s known to be problematic, there are certain repairs that you may need to make. Finally, if those repairs don’t work or the problem continues after you make them, it might be time to consider replacing your tankless water heater. Here’s a look at some of the potential issues and what you can do if they occur.

1. Your Tankless Water Heater Isn’t Working Properly
One of the first things that might go wrong with your tankless water heater is if it doesn’t start up properly. If the heating element doesn’t turn on or the fan doesn’t start spinning, there could be a problem with the electrical system and it might need to be addressed professionally.

2. Your Tankless Water Heater is Leaking
Another common issue with tankless water heaters is when they start leaking hot water. This could happen due to a variety of reasons including a broken pipe or faulty valve stem sealant. If this happens, you’ll need to take action quickly before the damage gets worse and your home becomes uninhabitable.

3. Your Tankless Water Heater Keeps Overheating
If your tankless water heater keeps overheating, it might be due to a problem with the thermostat. In some cases, this can be fixed by adjusting the temperature or by replacing the thermostat. If that doesn’t work, it might be time to replace the tankless water heater.

4. Your Tankless Water Heater is Having Problems Turning on or Stopping
If your tankless water heater isn’t turning on at all or it’s stopping suddenly, there could be a problem with the electrical system. In most cases, this can be fixed by replacing the wiring or by cleaning the contacts on the plug. If that doesn’t work, it might be time to replace your tankless water heater.

5. Your Tankless Water Heater is Damaging Your Home
If your tankless water heater is leaking hot water or it’s overheating, it could be damaging your home. This happens because the heat from the water can cause extensive damage to wood floors, drywall, and other components. If this happens, you’ll need to take action quickly before the damage gets worse.

How to Fix a Tankless Water Heater Yourself

If your tankless water heater is not producing hot water, there are a few things you can do to try and fix the issue yourself.

1. Check the fuses. If the power to your water heater is going in and out, this could be causing problems with the heating element. Replace any blown fuses with new ones.

2. Check for clogs. A clogged filter or drain can cause poor water flow and eventually a broken tankless water heater. Clear any obstructions with a plunger or snake before calling a professional.

3. Reset the thermostat. If none of these fixes work, resetting the thermostat may get your water heater up and running again. Turn off power at the breaker panel, then turn it back on to the correct circuit (usually either “house” or “water”) and wait 10 minutes for it to heat up completely before using it again.

If you’re still having trouble getting your tankless water heater to work, it may be time to call a professional.

Conclusion

A tankless water heater is a great option if you are looking to save money on your energy bill, but it can also be difficult to repair. In this article, we will go over the basics of how a tankless water heater works and what you should do if something goes wrong. Hopefully this will help you avoid any costly repairs down the line and keep your water hot without wasting any energy. Thanks for reading!
