Why does gas boiler keep cutting out?

If the water pressure in your boiler drops too low, it will cause the boiler to cut out. This can happen if there is a leak in the system or if the expansion tank is not properly charged.

2. Faulty thermostat:

A faulty thermostat can also cause your boiler to cut out. If the thermostat is not reading the correct temperature, the boiler will not be able to maintain the desired temperature and will eventually cut out.

3. Blocked condensate pipe:

The condensate pipe is responsible for draining away the water that is produced when the boiler burns fuel. If this pipe becomes blocked, it can cause the boiler to cut out.

4. Faulty flame sensor:

The flame sensor detects the presence of a flame in the boiler. If the flame sensor is faulty, it can cause the boiler to cut out.

5. Faulty ignition system:

The ignition system is responsible for igniting the fuel in the boiler. If the ignition system is faulty, it can cause the boiler to cut out.

6. Faulty fan:

The fan is responsible for circulating the hot air around the boiler. If the fan is faulty, it can cause the boiler to cut out.

7. Faulty pump:

The pump is responsible for circulating the water around the boiler. If the pump is faulty, it can cause the boiler to cut out.

If your gas boiler keeps cutting out, it is important to have it checked by a qualified technician to identify the cause of the problem and have it repaired.
