What it is

The 3-Way Motor Cartridge Assembly (part 3020380) is a directional water control cartridge used in Alpha Immergas combi boilers. It fits into the diverter valve body and moves to send heated water either to the central heating circuit or to the domestic hot water outlet. This is an unbranded alternative to the Alpha 3-way motor cartridge assembly 3020380.

Signs this part needs replacing

  • Hot water runs cold or lukewarm while the heating is calling for heat
  • Radiators warm up when a hot tap is opened
  • No hot water at the taps, or heating that will not come on at all
  • The diverter motor runs but the valve does not change position
  • Water weeping from the cartridge area of the valve body

Before you order

  • Confirm the number on the existing cartridge or in the boiler manual matches 3020380.
  • Inspect the valve body for scale and debris, as a worn cartridge often sits in a scaled body.
  • Check the O-rings and seals on the cartridge and replace them if they are perished.
