What it is
The Worcester Bosch 8737712788 is a motor for the diverter valve assembly used on Worcester Bosch Greenstar combi boilers. It drives the diverter valve to switch the boiler between domestic hot water and central heating operation. This is the motor component only, supplied under Worcester Bosch part number 8737712788.
Signs this part needs replacing
- The boiler does not switch reliably between central heating and domestic hot water.
- Hot water runs cool or fluctuates while the heating circuit stays warm.
- The diverter valve head does not move when the boiler calls for hot water.
- The motor runs continuously, stalls or is noisy during a demand change.
- Diverter valve fault codes are logged on the appliance.
Before you order
- Confirm the boiler model against the fit list above before ordering.
- Check the existing diverter valve head to confirm the motor is at fault rather than the valve body or cartridge.
- Note the appliance GC number where available to confirm the exact variant.
- Verify the part number 8737712788 matches the marking on the failed motor.
