How To Troubleshoot Common Boiler Problems

Posted on

You depend on your boiler to provide you with hot water on demand. Hot water is important for not only comfortable bathing, but for washing your clothes, dishes, and more. While most boilers can last 10 to 15 years before needing to be replaced, they may need maintenance along the way.  Fortunately, there are things you can do on your own to troubleshoot common boiler problems. These things may keep your boiler running for many more years, or they may prolong the need for full professional boiler repair. If boiler repair is ultimately needed, you may find that you save significant money by troubleshooting common problems on your own first.

Here are three common boiler problems and how you can troubleshoot them on your own, without the need for professional intervention. Working on your boiler like this is an excellent project for DIY enthusiasts, or for people who want to learn more about how to take care of the appliances in their homes by themselves.

1. Dirt or Sediment in the Water

Sometimes, you may find dirt or gravelly sediment coming out of your faucet or shower head. This is obviously not what you want from your water supply, as the idea is to keep things clean. Dirt counteracts that need. The good news is that fixing this problem is often very easy.

Simply turn off the gas or electricity to your boiler. Then, attach a hose to the drainage bib and drain the water out of the appliance. If there is dirt or sediment that has gotten into the unit, it will come out when you drain the water.

Remove the hose, turn the unit back on, and allow it to fill back up with water. You shouldn't have any more problems. If you do, call a professional boiler repair person to see where the dirt is getting into your unit.

2. A Rattling or Otherwise Noisy Boiler

In this case, the heating unit on your boiler may be loose and banging against other parts of the boiler as it operates. It might not be the heating unit, though. It could really be any pipe or other internal part, though the heating unit is the most common part to get loose.

To fix this, you simply need to secure the moving part. Pack foam insulation made for boilers around it, or secure it in its place with duct tape. You should not experience any more difficulties with noise after doing this.

3. Lack of Hot Water

One of the most annoying problems you can have with your boiler is a lack of hot water. This could have a number of causes, some of which will require professional boiler repair, while others can be fixed on your own.

According to HomeRepair.About.com, you should first try re-setting the circuit breaker to the boiler. This often fixes the problem. If it does not, then you should try re-lighting the pilot light, then adjusting the temperature on the thermostat by a few degrees.

If none of these things work, then professional repair is needed. However, you may be pleasantly surprised that a quick, easy fix is enough to get the hot water flowing again.


There are several simple, safe things you can do to troubleshoot your boiler if it has problems. Just remember, troubleshooting your own boiler repairs is only for simple problems with simple fixes.

If you encounter anything that is complex, you should always consult a professional boiler repair person, as attempting to fix something intricate without the proper training could injure you or break the boiler. Save yourself time and money by knowing when it's okay to fix it on your own, and when you need to call in a professional.
