What it is

The Johnson & Starley 1000-0301615 is a diverter valve head only, designed for Elbi diverter valve assemblies. It is used in Johnson & Starley Reno and Renoxtra combi boilers to control the flow of water between the central heating and domestic hot water circuits. The head is supplied with a clip.

Signs this part needs replacing

  • No hot water when the central heating is running
  • Central heating warms up when only hot water is demanded
  • Diverter valve head motor fails to move or makes a humming noise
  • Water leaks from the diverter valve head
  • Boiler displays a diverter valve fault code (if applicable)

Before you order

  • Check your boiler model against the fit list above
  • Confirm the existing diverter valve is an Elbi type
  • Ensure you only need the head, not the complete valve assembly
  • Check that the clip is present on your existing valve (a new clip is supplied)
