What it is
The Worcester Bosch 8748300913 is a printed circuit board (PCB) that acts as the central electronic control unit of the boiler. It governs every function through the thermostats, switches and sensors wired to it, and it continuously monitors internal conditions so the appliance only runs when it is safe to do so. This board is used on the Greenstar CDI conventional range.
Signs this part needs replacing
- The boiler fails to fire or repeatedly drops into lockout
- No heating or hot water even though there is a call for heat
- Fault codes relating to the control board or its sensor circuits
- Erratic behaviour, such as the fan, pump or ignition cycling without demand
- The appliance needs repeated resets before it will run
