A C1 fault code is generated when the fan has stopped during operation. This should not be confused with other fault codes whereby the fan is running too fast or fan running too slow. Things to check are fan, harness and control box. This should only be carried out by a Gas Safe registered engineer.

The C1 fault code for Worcester boilers relates to a fan that has stopped running. This isn’t to be confused with other boiler fault codes where the fan is running too fast, too slow, or hasn’t been recognised as working, before the boiler starts up. A Gas Safe engineer will be required to investigate the issue
