What should I do if my Worcester Bosch boiler displays a fault code?
If your boiler shows a fault code, the first step is to note the code down. Sometimes a simple reset can clear minor errors. However, if the fault persists or you are unsure, it’s safest to contact a Gas Safe registered engineer for diagnosis and repair.
Can I reset my Worcester Bosch boiler myself?
Yes, most Worcester Bosch boilers have a reset button, usually located on the front panel. Press and hold the reset button for a few seconds. If the fault code reappears after resetting, it indicates a deeper issue that needs professional attention.
What does it mean if multiple fault codes are showing at once?
Multiple fault codes could suggest several issues or a communication error within the boiler. It’s important not to ignore this — multiple faults usually require a professional diagnosis to avoid further damage.
Is it dangerous to keep using my boiler if a fault code appears?
It can be! Some codes relate to minor issues, like low pressure, but others (such as flame detection faults) can be serious. If you're unsure or notice strange smells, sounds, or no heat/hot water, switch off your boiler and call a qualified engineer immediately.
How often should I have my Worcester Bosch boiler serviced?
We recommend servicing your boiler once a year. Regular servicing helps catch problems early, keeps your boiler running efficiently, and protects your manufacturer's warranty.
Are Worcester Bosch fault codes covered under warranty?
If your boiler is still under warranty and has been serviced annually, many fault repairs will be covered. Always check your warranty documentation or ask us at Heatwise Heating for advice.
