When it comes to home heating, a reliable and efficient boiler is essential. However, boiler issues can arise, and understanding error codes is crucial for troubleshooting and resolving problems promptly.
In this blog post, we'll focus on the Worcester Bosch boiler error code C6. We'll explore its meaning, potential causes, and suggested fixes.
Also we will discuss the advantages of upgrading or replacing your boiler with a modern, more efficient model if the C6 error persists or if your boiler is completely broken.

Worcester Bosch boilers display error codes to help homeowners identify and address specific issues. The C6 error code typically indicates a problem with the fan or flue.
The boiler's fan plays a vital role in proper combustion, while the flue ensures the safe discharge of combustion gases from the boiler to the outside.
A faulty or malfunctioning fan can trigger the C6 error code. This may be due to a worn-out fan motor, damaged fan blades, or an obstruction preventing the fan from operating correctly.
A blockage or restriction in the flue can also trigger the C6 error code. This can be caused by debris, birds' nests, or other obstructions, preventing the proper exhaust of combustion gases.
The C6 error code may also indicate an issue with the air pressure switch, which is responsible for monitoring and ensuring the correct airflow within the boiler. A malfunctioning pressure switch can prevent the fan from operating correctly, triggering the error code.
While some DIY fixes are possible for certain boiler issues, the C6 is a complex problem that will require the expert services of a Gas Safe registered engineer.
The engineer will carefully inspect the fan for any visible signs of damage or blockage. They will ensure it spins freely without obstruction.
If there is accumulated dust or debris affecting its performance, they will clean the fan blades meticulously. If the fan is found to be damaged or worn out, the engineer will suggest a replacement.
The engineer will thoroughly examine the flue for any obstructions and remove them with caution. Following safety guidelines, they will ensure the boiler is turned off before attempting
The air pressure switch associated and tubing will be inspected by the engineer for any damages or blockages.
They will clear any obstructions and verify the proper functioning of the switch. If the air pressure switch is found to be faulty, the engineer will conduct testing and replace it accordingly.
The cost of an engineer assessing and fixing any C6 related issues will be dependent on that particular engineer or organisation’s work rate fees.
Here at iHeat we offer boiler servicing by an expert Gas Safe engineer as even without any signs of damage, your boiler would benefit from a yearly inspection to make sure everything is working as it should.
If the C6 error persists despite attempting the suggested fixes or if your boiler is completely broken, it may be an opportune time to consider upgrading or replacing your boiler with a modern, more efficient model. Here's why:
Modern boilers are designed with advanced technology and higher energy efficiency ratings. Upgrading to a modern boiler can result in significant energy savings and lower heating bills in the long run.
Newer boilers offer improved performance and reliability. They incorporate intelligent features and controls, allowing for better temperature management, increased comfort, and optimised energy usage.
Older boilers are often less eco-friendly and contribute to higher carbon emissions. Upgrading to a modern, environmentally conscious boiler can help reduce your carbon footprint and support sustainability efforts.
While the upfront cost of a new boiler may seem significant, the long-term cost savings in energy bills, repairs, and maintenance can make it a wise investment.
Additionally, many manufacturers offer extended warranties on new boilers, providing added peace of mind.
Modern boilers can be integrated into smart home systems, allowing for remote control, scheduling.
Apart from the obvious complete breakdown, there are several signs to keep on the lookout for that may be warning you that your boiler is on its way out.
Leaks can be fixed depending on their severity, but should always be treated as a priority issue that if sizeable or fast flowing can be a major problem, and needs rectifying ASAP.
Repeated error codes can also be a cause for heating concern especially if they result in a boiler being ‘locked out’ (system forced shut down) for damage limitation purposes.
If your boiler regularly needs some kind of maintenance, or performs sub-optimally most of the time there may be serious component issues.
Any boiler issue is obviously important to get remedied as soon as possible, but in a triage system of urgency, some issues take precedence.
You can consider any of the following an emergency boiler matter:
Suspected gas leak (natural gas or carbon monoxide)
No heating or hot water during winter (especially important if you have children in the home)
Water is streaming out of a boiler or pipe at a very quick rate
Despite recent misconceptions that there is a looming ‘ban’ on gas boilers, this is actually incorrect!
It’s still completely legal to buy and install a new gas boiler in any type of property, the supposed ‘ban’ only applies to new build properties after 2025.
There is no current financial penalty to keeping an existing gas boiler in any type of property past 2025, or installing a new gas boiler in any pre existing property past 2025.
New gas boilers blend efficiency, safety, cost effectiveness and versatility, hence their constantly rising popularity.
