To reset the Viessmann Vitodens 200 Boiler, locate the reset button on the control panel. Press and hold the reset button for a few seconds until the display indicates that the boiler has been reset.
First, check the thermostat settings and ensure they are correct. Make sure the boiler has power and is turned on. Inspect the pressure gauge to ensure the system pressure is within the recommended range (usually 1-1.5 bar). If the issue persists, consider bleeding the radiators or contacting a professional technician.
To increase the water pressure, locate the filling loop beneath the boiler. Open the valves on the filling loop slowly and monitor the pressure gauge. Once the pressure reaches the recommended level (1-1.5 bar), close the valves.
It is recommended to have an annual maintenance check performed by a qualified technician. This includes inspecting the system, cleaning components, checking the flue, and ensuring the boiler is operating efficiently and safely.
Turn off the heating system and allow the radiators to cool. Use a radiator key to open the bleed valve at the top of the radiator. Hold a cloth under the valve to catch any water. When the hissing stops and water starts to flow steadily, close the valve.
Strange noises can be caused by air in the system, low water pressure, or a faulty pump. Check the pressure gauge and bleed radiators if necessary. If the noise persists, contact a professional technician for further diagnosis.
Error codes are displayed on the boiler's control panel. Refer to the user manual for the specific meanings of each code and suggested troubleshooting steps. If unsure, consult a professional technician.

Modern Vitodens 200 boilers do not use a pilot light. If the boiler is not igniting, check the power supply, gas supply, and ensure that there are no error codes displayed. Contact a professional if necessary.
