If your Worcester Bosch boiler has a problem, it will likely shut down, a process known as a ‘lockout,’ to prevent further potential damage and keep you and your home safe.
At this point, you should see a boiler error code, also known as a fault code, displayed on the interface. The goal of this code is to make it easier for you or the engineer to identify the problem and get it fixed as soon as possible.
We’ve compiled a comprehensive list of the brand’s most common boiler error codes in this guide. This should give you an idea of what’s wrong with your boiler and how much it might cost to fix it.
