On this page, we will list all the possible error codes as well as the faulty codes you can experience with Zanussi boiler. Knowledge of these codes can help you understand what is going on in your boiler and will enable you to inform your Gas Safe engineer of the specific issue.

If your boiler warranty is still valid, you can call the Zanussi and they should fix it for you. However, to get this service, you have to meet the conditions of your warranty, such as getting your boiler serviced annually and so on.
