Write the Fault Code Down
Before resetting the boiler, note the complete code and boiler model. A photograph of the display can also be useful when booking an engineer.
Why Fault Codes Need Interpretation
A code may refer to ignition, pressure, temperature, circulation, communication or another operating condition. The same symptom can sometimes have several underlying causes.
That is why accurate diagnosis involves testing rather than replacing the first component associated with the code.

Should You Reset a Fault Code?
Follow the user instructions for your specific boiler. If a normal user reset is permitted, one reset may restore operation after a temporary fault.
If the same code returns, further resets are unlikely to correct its cause.

Frequently Asked Questions
Does a boiler fault code tell me what part I need?
Not necessarily. It normally identifies the condition detected by the control system, which then guides further diagnosis.
Should I clear the code before calling an engineer?
No. Record the code first because it may provide useful information for the engineer.
