What it is

The diverter valve actuator assembly is a Worcester Bosch hydraulic component used in Greenstar Heatslave oil-fired boiler ranges. It drives the diverter valve inside the appliance, moving the valve between its positions so that water flow is directed to the correct circuit for heating or hot water. The assembly is supplied as a single unit and carries a 1 year manufacturer guarantee.

Signs this part needs replacing

  • No hot water while the heating continues to run as normal
  • Heating circuit warming up when only hot water is called for
  • Actuator head not moving, or moving only part way, when the valve is demanded
  • Motor running continuously or buzzing without shifting the valve spindle
  • Valve stuck in one position, leaving the appliance unable to switch between heating and hot water

Before you order

  • Confirm the appliance model and serial number against the compatibility list, as the actuator is used across several Heatslave variants
  • Check the existing part number on the appliance and cross-reference it with 1015429 before ordering
  • Inspect the valve body and seals while the actuator is removed, as a worn spindle or leaking seal will affect the new assembly
  • Work on the hydraulic side of the appliance should be carried out by a competent engineer
