If you’re experiencing issues with your Worcester boiler in Wokingham or surrounding areas, understanding the error codes displayed on your unit can save you time, money, and the discomfort of being without heating or hot water. As heating engineers in Wokingham, we’ve seen virtually every error code that Worcester boilers can throw up, and we’re here to help you make sense of them.
Common Worcester Boiler Error Codes
EA/E9 Error: Flame Detection Issues
This error indicates that your boiler is having trouble detecting a flame. This could be caused by:
- Gas supply issues
- Faulty flame detection electrode
- Problems with the gas valve
Quick fix: Try resetting your boiler by pressing the reset button (typically marked with an ‘R’). If the error persists, it’s time to call a professional as this could indicate a component failure or gas supply issue.
E5 Error: Flow Sensor Problem
The E5 error relates to your boiler’s flow temperature sensor. This sensor monitors the water temperature as it leaves the boiler. Issues could be:
- Sensor failure
- Wiring connection problems
- Water circulation issues
Quick fix: Check if all radiator valves are open and ensure your system pressure is between 1-1.5 bar. If pressure is low, follow our guide on handling pressure loss.
A1/E1/EA Error: Ignition Failure
This is one of the most common errors and indicates that your boiler has failed to ignite. Causes include:
- Gas supply issues
- Faulty ignition leads
- Ignition electrode problems
- Blocked flue
Quick fix: First, check that your gas supply is working by confirming other gas appliances are working. Then try resetting your boiler. If problems persist, you’ll need a Gas Safe engineer to investigate.
H07 Error: Low System Pressure
Your Worcester boiler requires the correct water pressure to operate safely. If the pressure drops below 0.5 bar, this error will appear.
Quick fix: You can repressurise your system using the filling loop attached to your boiler. Aim for a pressure reading between 1-1.5 bar, but check your specific model’s manual for the recommended pressure.
227/228 Error: Flue Gas Issues
These error codes relate to flue gas problems and suggest potential blockages in your flue pipe.
Quick fix: This is definitely NOT a DIY fix. Any issues with flue gases require a Gas Safe registered engineer as they involve dangerous carbon monoxide risks.
What To Do When You See Error Codes
- Document the code: Write down the exact code displayed before doing anything else.
- Check the manual: Your boiler’s manual will explain specific codes for your model.
- Try a reset: Many minor issues can be resolved with a simple reset.
- Check your pressure: Low pressure is a common cause of boiler errors.
- Call a professional: If the error persists or involves gas supply, ignition, or flue issues, it’s time to call us.
When To Call A Professional
While some minor issues can be resolved by homeowners, many Worcester boiler error codes indicate problems that require professional attention. You should always call a Gas Safe registered engineer if:
- The error relates to gas supply or ignition
- You’ve tried resetting and the error returns
- There are any flue-related errors
- You smell gas (in which case, call the Gas Emergency line immediately on 0800 111 999)
- You’ve tried the basic fixes and the problem persists
Remember, gas appliances can be dangerous if not properly maintained. Regular boiler servicing is the best way to prevent these errors from occurring in the first place.
