Why does my boiler keep cutting out?
A boiler keep cutting out is the most common issue for boiler users, and sometimes this issue becomes easy to fix, but sometimes it becomes more complicated and irritating to solve. It may need professional attention to be solved if the issue is not fixable by yourself. You must know the basic troubleshooting and ways to shut off your boiler to reset settings.
What Does It Mean When a Boiler Cuts Out?
When a boiler “cuts out,” it suddenly indicates that it goes off for safety reasons. Your boiler design is to get cut out automatically to protect the boiler from damage or control unsafe operation. Modern boilers are equipped with smart sensors and controls that stop the system when something isn’t working as it should.
Common Reasons Your Boiler Keeps Cutting Out
There are some common and most important factors why boilers get cut out, like-
1. Low Boiler Pressure
Low water pressure is one of the most common reasons for getting a boiler cut out because a boiler needs a sufficient water level to work properly. If the boiler has low water, then it will cut out to stop overheating or internal damage. This usually happens if your boiler has an issue with bleeding radiators or due to small leaks in the system.
2. Thermostat Issues
If the thermostat is located near a heat source or isn’t communicating properly with the boiler, then it will shut down because a faulty or poorly placed thermostat can cause your boiler to cut out unexpectedly, or it may show incorrect signals and make your boiler system cut out.
3. Overheating
Overheating is a common problem for boilers; it will shut down if the water supply is not sufficient. There will be some main reasons for not getting a proper water supply, like
blocked pipes
poor water circulation
malfunctioning pump.
4. Condensate Pipe Frozen
The condensate pipes, which are working to remove acidic wastewater from the boiler, can freeze during colder months. The boiler is unable to drain properly and may cut out repeatedly in colder months due to frozen pipes, and it is a very common issue in winter months and most cold areas.
5. Faulty Sensors or Components
If sensors are not working properly, like pressure sensors, temperature sensors, or internal valves can make issue to heat over time. When these parts fail, the boiler may shut down even if everything else appears normal.
6. Airlocks in the System
An airlock in the system or trapped air can cause an issue with supplying hot water from circulating correctly, which can lead to temperature imbalances and sudden shutdowns.
Basic steps to Fix It
Some boiler cut-out issues can be resolved at home with some basic troubleshooting steps
Check the pressure gauge and fix it with the recommended level (top it up if it’s below the recommended level, usually 1–1.5 bars). You can reset your boiler as per the company or brand directions. Check all the basic troubleshooting and hand able issue.
