What it is

The BI1475102 is a control knob manufactured by Biasi for use on Parva M90 series gas boilers. It fits onto the appliance control spindle and provides the manual grip for adjusting the associated boiler setting. This is a service part for the Parva M90 platform.

Signs this part needs replacing

  • The knob is missing from the control spindle.
  • Cracking or splitting is visible in the knob body or its fixing.
  • The knob spins freely on the spindle instead of turning the control.
  • The internal splines or flats are worn and the knob slips under normal use.
  • The knob no longer sits flush or securely against the control panel.

Before you order

  • Confirm the boiler model against the fit list above, using the appliance data badge.
  • Check the GC number on the data badge where one is shown.
  • Remove the existing knob and check the spindle type and profile match the replacement.
  • Confirm the control the knob operates, so the correct function is replaced.
