Boilers play a pivotal role in keeping our homes warm and cosy, and when they encounter issues, it's crucial to understand the reasons why. This error code is common in the Worcester Bosch Greenstar 8000.

Identifying and fixing the fault code is crucial, especially if you've noticed, your boiler is operating at an excessively high temperature.

Causes of the 2965 Error Code

Flow Temperature Running Too High
The flow temperature reaching a high level is the primary cause behind this error code. This may occur due to defective components or a glitch in the electronics.
HCM Malfunction
The proper functioning of the heat control mechanism (HCM) is essential for the boiler to run smoothly. A malfunctioning HCM (highlighted by the F0 272 error code) indicates either a defective HCM or poor connections.

Boiler Flow Temperature?
Flow Temperature Defined:
First, flow temperature refers to the temperature at which the water is heated before it's circulated to the radiators. Water is then pumped around the system when the temperature has reached 80°C. Once completed, the water returns to the boiler at a slightly cooler 60°C. Typically, gas boilers flow and return operate between 80°C/60° flow and return temperatures.

However, recent research has shown that these high temperatures prevent modern condensing gas boilers from achieving their peak efficiency.

The Importance of Turning Down the Heat
By turning down the flow temperature, you can potentially unlock a boost in efficiency. This minor tweak can greatly impact energy bills, as your boiler works smarter rather than hotter!

Lowering the flow temperature allows your boiler to operate in a more efficient zone, where it can possibly achieve 'A' rated efficiencies.


How to fix the 2965 Error Code

If this error code pops up in the display panel of your Worcester Bosch Greenstar 8000 boiler, try this:
Reset Your Boiler
Sometimes, a quick boiler reset is all it takes to resolve the issue. This simple procedure can reset the system and bring things back to normal. Always follow the manufacturer's guidelines first before taking this action.

Here's how:

  • Locate the reset button on your Worcester boiler. It's usually a small button with a circular arrow symbol.
  • Press and hold the reset button for the recommended time until you see the display change or hear a distinct 'beep'.
  • Release the button after the recommended time and wait for the boiler to go through its reset process.
If the error code vanishes and your boiler resumes normal operation, you're good to go. However, if the 2965 error code persists, it's time to seek professional help.

Remember, while some boiler issues can be resolved with a simple reset, others may require the assistance of a gas-safe engineer. It's always best to err on the side of safety, as Boilers are complex appliances.

A qualified heating engineer will adjust your boiler's settings to find that efficiency 'sweet spot'. Maintaining your boiler regularly while performing an annual boiler service can bring numerous benefits and help save time and money.
