Homeowners can find problems with their heating system by using boiler error codes. A boiler error code can appear on the display due to problems like low water pressure, gas supply issues, or faulty sensors. Some minor issues with your boiler can be taken on at home, while others will require the help of a qualified heating engineer in Streatham. It is important to pay attention to these boiler faults as they can potentially increase your energy bills, cause inefficient heating, or even cause a breakdown completely. This article aims to explain the five most common boiler display error codes, what these codes mean, and when to get in contact with a local plumber in Streatham.
1. F22 – Low Water Pressure (Worcester Bosch & Vaillant Boilers)
What the Code Means
The F22 error code indicates that the water pressure is too low inside the boiler. This is often the case when bleeding the radiators due to leakage or loss of pressure over the years.
What Are The Causes
- Leakage in the heating system
- Trapped air in the radiators
- Broken pressure sensor
How To Resolve The Fault
- Check the pressure gauge on the boiler. This should read between 1.0 and 1.5 bar.
- Use the filling loop (a small tap directly beneath the boiler) to increase the water pressure.
- If the pressure keeps dropping, you should arrange for a plumber in Streatham to check for leaks.
2. F27 – Blocked Condensate Pipe (Vaillant Boilers)
What It Means
F27 appears when the boiler’s condensate pipe is blocked. This pipe removes excess water from the
boiler and can freeze in winter.
Possible Causes
- Frozen condensate pipe
- Blockage due to dirt or debris
- Faulty flame sensor
How To Fix It
- If frozen, pour warm water over the pipe to thaw it.
- Check for blockages and clear any debris.
- If the problem continues, call a heating engineer in Streatham.
3. EA – No Flame Detection (Worcester Bosch Boilers)
What It Means
This error means the boiler cannot detect a flame, so it will not ignite.
Possible Causes
- Gas supply issue
- Faulty gas valve
- Blocked burner or ignition failure
How To Fix It
- Check if your gas supply is on.
- If gas is working elsewhere, reset the boiler.
- If the error returns, call a Gas-safe registered plumber in Streatham.
4. F75 – Pressure Sensor Error (Vaillant Boilers)
What It Means
This code means the boiler’s pressure sensor is not working correctly. It may not detect changes in water pressure, which can stop the boiler from heating.
Possible Causes
- Defective pressure sensor
- Faulty pump
- Airlock in the system
How To Fix It
- Try resetting the boiler.
- Call a heating engineer in Streatham to check the pump and sensor to see if the error stays.
5. 229 – Loss of Flame (Worcester Bosch Boilers)
What It Means
The flame inside the boiler has gone out, and the boiler cannot relight itself.
Possible Causes
- Gas pressure problem
- Blocked pilot light
- Faulty ignition system
How To Fix It
- Check if the gas supply is on.
- Reset the boiler.
- If it does not restart, call a professional plumber in Streatham.
