Common boiler issues and how to fix them

1. Boiler Keeps Turning Off (Boiler Cycling)

This issue is when your boiler keeps turning itself off, which can be caused by several factors such as low water pressure, a problem with the thermostat or a closed valve causing insufficient water flow.

How to fix it

Check your boiler’s pressure gauge. If it’s below 1, you may need to increase the pressure. If the problem persists, it may be time to call a professional like Boiler Boys London to investigate and rectify the issue.

2. No Heat or Hot Water

This is the most common boiler issue homeowners face. It could be due to a broken diaphragm and airlock, failed motorised valve, or issues with the thermostat.

How to fix it

First, check your thermostat settings and the boiler pressure. If they seem alright, the problem may be more serious, and a boiler service professional should look at it.

3. Leaking and Dripping

Various issues can cause your boiler to leak or drip, including a broken internal component like a pressure valve or pump seal.

How to fix it

Identifying the source of the leak can give insight into the cause. However, fixing a leak or drip usually involves replacing the faulty component, which should be done by a Gas Safe registered engineer.

4. Strange Noises

Boilers can sometimes make strange noises like whistling, gurgling, or banging. This could be due to air in the system, low water pressure, or limescale accumulations causing 'kettling'.

How to fix it

For minor issues, bleeding your radiators can remove air in the system. However, for persistent noises, especially 'kettling', you should call a boiler service professional.

5. Radiators Not Getting Hot

If your radiators are not heating up, there could be a build-up of sludge or air in your system that's blocking the flow of hot water.

How to fix it

You can try bleeding your radiators to remove any air. If this doesn't work, your system might require a power flush, which should be carried out by a professional.
