What should I do if my Worcester Bosch boiler displays an error code?
If your boiler displays an error code, the initial step is to write it down. Often, a quick reset can resolve minor issues. However, if the problem continues or you're uncertain, it's best to reach out to one of our Gas Safe registered engineers for proper diagnosis and repair.
Can I reset my Worcester Bosch boiler myself?
Indeed, most Worcester Bosch boilers come equipped with a reset button, typically found on the front panel. Simply press and hold this button for a few seconds. If the fault code shows up again after you've reset it, this suggests there may be a more serious problem that requires the help of a professional.
What does it mean if multiple error codes are showing at once?
Having multiple error codes might indicate various problems or a communication glitch in the boiler. It's crucial to pay attention to this, as several faults often need a professional assessment to prevent additional damage.
Is it dangerous to keep using my boiler if an error code appears?
Absolutely! Some error codes indicate minor problems, like low pressure, while others, like flame detection issues, can be quite serious. If you're feeling uncertain or detect unusual smells, sounds, or lack of heat or hot water, it's best to turn off your boiler and contact one of our qualified engineers right away.
How often should I have my Worcester Bosch boiler serviced?
We suggest having your boiler serviced annually. Routine maintenance allows you to identify issues early, ensures your boiler operates efficiently, and safeguards your manufacturer's warranty.
Are Worcester Bosch error codes covered under warranty?
If your boiler is still within its warranty period and has received annual maintenance, many repairs for faults will be included. Be sure to review your warranty documents or reach out to us at Matt Grange for guidance.
