What it is
The Worcester Bosch 87161431070 is a circulation pump used on the FSN range of gas-fired combi and system boilers. It moves primary water around the heating circuit and through the domestic hot water plate heat exchanger, so it runs whenever there is a call for heat or hot water. The pump is supplied by Worcester Bosch as a direct replacement for the unit fitted at manufacture.
Signs this part needs replacing
- No heating or hot water despite the boiler firing and the controls calling for demand
- Pump body hot but the pipework either side staying cold, indicating the impeller is not turning
- Grinding, humming or rattling noise from the pump housing
- Boiler repeatedly locking out or tripping on overheat because circulation has stopped
- Visible weeping from the pump body, flange or shaft seal
Before you order
- Confirm the boiler model and serial number against the compatibility list, as FSN variants differ between combi and system builds
- Check the pump currently fitted against part number 87161431070 or the alternative numbers listed above
- Allow for a gasket or seal at the pump connection if the existing one is disturbed during removal
