Your boiler may be on a separate circuit, so if the rest of your home has electricity but the LCD display on your boiler isn’t displaying anything your boiler may not be receiving power and you may need to call an electrician or Gas Safe engineer. Check your property has running water from the cold taps, that your gas is working by lighting the hob or gas fire and that your electricity is working by turning on a light. If you have a prepay meter, make sure you have credit. If your boiler isn’t working but it isn’t displaying a fault code either then check your water, gas, and electricity supplies to ensure there is no issue with supply.
Only a Gas Safe registered engineer should attempt to fix your boiler. This error code list is a guide to help you identify the issue with your Viessmann boiler.
