What it is

The Alpha Diverter Valve Motor Assembly, part number 1.018064, is a motorised head that drives the diverter valve on Alpha gas boilers. It moves the valve between heating and hot water positions so the appliance can direct flow to the correct circuit. It is listed for the CD and HE families as well as InTEC models.

Signs this part needs replacing

  • No hot water while the heating continues to run, or the reverse.
  • The valve head stays in one position and does not move when demand changes.
  • Motor runs continuously or the head buzzes without driving the valve.
  • Boiler locks out or reports a diverter valve fault.
  • Water leaking from the motor head area.

Before you order

  • Confirm the boiler model and check the existing motor head label against part number 1.018064.
  • Compare the terminal and mounting arrangement on the existing head with the new assembly.
  • Check whether the valve body or cartridge also needs attention, as the motor head and valve body are separate items.
  • Isolate the electrical supply and drain down as required before fitting.
