How to Reset a Viessmann 050 Boiler: Step-by-step
Resetting your Viessmann 050 boiler is a straightforward process, but it’s crucial to follow the manufacturer’s guidelines to ensure safe and efficient operation. Here’s a step-by-step guide on how to reset your boiler:
System Pressure: Before initiating the reset process, check the system pressure on the pressure gauge. The pressure should ideally be between 1.0 and 1.5 bar when the system is cold. If the pressure is too low, you may need to repressurise the system.
Gas Supply: Ensure that you know where the gas supply shut-off is. It’s good to know where it is, just in case. The supply should be open so the boiler can get gas when it needs it.
Electrical Supply: Make sure that the electrical supply to the boiler is switched on. Check the fuse box to ensure that the circuit breaker for the boiler is in the ‘ON’ position.
Initiate Reset: Hold the ‘Mode’ and ‘OK’ buttons for 2 seconds. It’s as simple as that.
Check Display: Look at the boiler’s display panel. If you see any flashing symbols or fault codes (e.g., F2), consult the manual or contact your local heating contractor for troubleshooting.
Final Checks: Make sure that the radiators are heating up and that hot water is available once the boiler is back up and running. If you encounter any issues, consult the manual or get in touch with a qualified technician.
- Never attempt to open the boiler casing or tamper with internal components.
- If you smell gas or suspect a gas leak, follow safety protocols and call The National Gas Emergency Helpline 0800 111 999.
By following these steps carefully, you can successfully reset your Viessmann 050 boiler and restore it to optimal working condition. However, if you experience recurring issues, it’s advisable to consult a qualified heating engineer for a thorough inspection and diagnosis.
