What it is
The Worcester Bosch 87172043450 is a motor used within the hydraulic section of Worcester Bosch Greenstar boilers. It drives internal component movement so the appliance can switch between heating and hot water demand without interruption. The motor is listed under diverter valves and hydraulics spares and is built for the Greenstar HE, HE Plus, ICC2 and ICS1 FSN ranges.
Signs this part needs replacing
- Hot water runs cold or only arrives intermittently while the boiler is firing
- The diverter valve does not move between heating and hot water positions
- Radiators warm up when only hot water is being drawn
- The boiler locks out or reports a fault after a demand change
- A whirring or clicking noise comes from the hydraulic assembly with no change in boiler operation
