What it is
The Worcester Bosch 8748300917 is a printed circuit board (PCB) for Greenstar FS regular gas boilers. It carries the control electronics that sequence ignition, monitor the flame, and regulate fan, pump and burner operation through a heating or hot water demand. It is the board used across the Greenstar FS 30CDi and 42CDi ErP regular range, in both natural gas and LPG variants.
Signs this part needs replacing
- The boiler shows no response to a heating or hot water demand, with the display dead or blank.
- Repeated lockouts that clear only after a power cycle, or lockouts that will not clear at all.
- The fan, pump or burner fails to start even though the demand and thermostat signals are present.
- Intermittent shutdowns, erratic display behaviour or fault codes that return after resetting.
- Visible damage on the board itself, such as scorching, a blown track or a swollen component.
Before you order
- Check the appliance GC number and model variant against the compatibility list above; the 30CDi and 42CDi ErP regular models use different GC numbers.
- Compare the part number on the existing board with 8748300917 and the alternative numbers listed below before ordering.
