What it is

The Biasi BI2175101 is a pump capacitor used on Biasi gas boilers, including the Riva Plus range. It provides the starting torque the circulating pump motor needs to run, so a failed capacitor stops the pump from starting or running reliably. It is a service part for the boiler's central heating circulation pump.

Signs this part needs replacing

  • The circulating pump hums but does not start or turn over
  • The pump runs intermittently or fails to start from cold
  • The boiler locks out or reports a circulation-related fault
  • The pump overheats or the motor trips during operation
  • Pump performance drops after the capacitor has aged

Before you order

  • Confirm your boiler model against the fitment list above
  • Check the capacitance and voltage rating marked on the existing capacitor before ordering
  • Isolate the electrical supply and confirm the pump is not seized before replacing the capacitor
  • Check the pump body and impeller for damage, as a failed capacitor can accompany a worn pump
