What should I do if my Vaillant boiler displays an error code?
If your boiler shows an error code, the first thing to do is jot it down. A simple reset can often fix small problems. But if the issue persists or you're unsure, it's a good idea to contact one of our Gas Safe registered engineers for a thorough diagnosis and repair.
Can I reset my Vaillant boiler myself?
Most Vaillant boilers are designed with a reset button located on the front panel. To use it, just press and hold the button for a few seconds. If the fault code reappears after resetting, it may indicate a more serious issue that needs professional assistance.
What does it mean if multiple error codes are showing at once?
Encountering several error codes could suggest different issues or a communication error within the boiler. It's important to take note of this, as multiple faults typically require a professional evaluation to avoid further damage.
Is it dangerous to keep using my boiler if an error code appears?
Of course! Certain error codes point to small issues, such as low pressure, while others, like problems with flame detection, can be more serious. If you're unsure or notice any strange smells, sounds, or if there's a lack of heat or hot water, it's a good idea to switch off your boiler and reach out to one of our skilled engineers immediately.
How often should I have my Vaillant boiler serviced?
We recommend getting your boiler serviced once a year. Regular maintenance helps you catch problems early, keeps your boiler running smoothly, and protects your manufacturer's warranty.
Are Vaillant error codes covered under warranty?
If your boiler is still under warranty and has had its yearly maintenance, many repairs for issues will be covered. Don't forget to check your warranty papers or contact us at Matt Grange for assistance.
