The C6 fault is usually related to an issue with the boiler fan the PCB will have detected that the fan is running at either too high or low a speed depending on the model of the boiler. You will need to contact a suitably qualified Gas Safe Registered engineer diagnose the fault and repair the boiler.

A C6 fault code can vary depending on the model but generally is triggered when the PCB recognizes that there is a problem with the fan. This could be the fan running too fast, too slow or not running at all. Things to check are fan harness and connector, connections of the control box, fan operation and PCB.

With a C6 fault code showing, the PCB in the boiler has detected a fault with the fan. This is mainly the fan speed is too low, or possibly a blockage or airflow restriction within the boiler. A Gas Safe registered engineer would need to investigate further and test the fan and flue flow of the boiler.

Fault codes are always model dependant. Wishing the Worcester Bosch model range, the C6 fault code predominately means the "fan speed is too low" This can be a result of a number of things but the components to check usually are either: 1 - Fan assembly 2- Fan harness 3 - PCB Obviously with the aid of a multimeter further tests would need to be carried out to highlight which component/components has failed & therefore require to be replaced.
