Viessmann Boiler Problems and Repairs

Although Viessmann boilers are among the best in the world, they can still develop problems and sometimes need a qualified engineer to carry out repairs. Getting your boiler serviced each year should help to minimise issues and ensure any faults are rectified before they become expensive problems. If your Viessmann boiler isn’t working properly or you would like to know more about typical issues, you can read our guide to Common Viessmann Boiler Problems and Repairs. Our helpful guide includes information on common Viessmann boiler issues and what you need to do next should any of them occur.

Viessmann Boiler Fault Codes

If something goes wrong with your Viessmann boiler, it may display a fault code to let you know that it requires attention. The fault codes help your engineer to quickly identify problems with your heating and hot water system so that the issue can be resolved and the fault can be cleared promptly. Some faults are more serious than others, however, small problems can quickly become big ones if left too long, so it’s best to deal with them right away. If a fault code has appeared on your Viessmann boiler and you want to know what it means, you can read our handy guide to Viessmann Boiler Errors and Fault Codes.

Viessmann Boiler Cover

If you want to keep your Viessmann boiler running well then investing in an annual servicing & repair plan will give you what you need. Viessmann offers a direct servicing option that you can book and pay for in one go or you can choose Domestic and General to cover your boiler and pay by monthly instalments.

In some cases and depending on which boiler model you choose, the warranty can be extended free of charge or at an additional cost. Our guide to the Viessmann Boiler Warranty explains what is covered by the warranty and includes information on the terms and conditions, as well as how you can register the warranty.
