Worcester Bosch CDI C6 fan fault code explained

This is a video of a Worcester Bosch Greenstar CDI with the C6 “fan fault” fault code.

The C6 fault code on the Worcester Greenstar CDI range of boilers generally means that the fan has failed.

Once you see the C6 fault code on a Worcester Greenstar CDI boiler, it generally won’t go away even with a reset, and generally means you will have no hot water and no heating.

In our experience most of the time the C6 fault code means that the fan has failed.

Sometimes the fan can work intermittently but in general once you see this fault code it’s there to stay, and your boiler will more than likely need a replacement fan to continue working.

Neil was quick to reply to my enquiry, arranged an appointment to come really quickly and came at the time he said. He had all the parts required to fix my boiler the same day. Really thorough checking everything over and worked cleanly. Would highly recommend and will definitely use him in the future.
