What it is

The throttle disc (2.4) is a Worcester Bosch gas boiler component, supplied under part number 87001001820. It sits within the gas train and is used to set the gas flow rate through the appliance, so the size marked on the disc matters. It is listed as a gas boiler spare.

Signs this part needs replacing

  • Combustion readings that cannot be brought into the specified range during servicing
  • A gas rate that is persistently high or low with no other cause identified
  • Signs of damage, distortion or blockage at the disc itself when the gas train is opened
  • Poor or unstable flame pattern traced to gas flow through the appliance

Before you order

  • Confirm the appliance model and gas type against the fitment list above
  • Check the existing disc marking to confirm the 2.4 size is the one required
  • Compare the part number on the existing component with 87001001820
  • Gas train work must be carried out by a competent registered engineer
