What it is

The Vaillant 0020059444 is a 3-way cable tree (wiring harness) used on Vaillant VWS series heat pumps. It provides the electrical connection between the 3-way valve and the appliance control, allowing the valve to be driven and its position fed back. It is a complete harness assembly with the connectors required for the 3-way valve circuit.

Signs this part needs replacing

  • The 3-way valve fails to move, or moves erratically, with no fault in the actuator itself
  • Intermittent fault codes relating to the 3-way valve or diverter circuit
  • Visible chafing, heat damage or cracked insulation on the harness
  • Loose, corroded or pushed-back terminals at the valve plug or control board end
  • The valve operates correctly when the harness is wiggled or reseated

Before you order

  • Confirm your appliance model matches one of the VWS models listed above
  • Check the connector count and layout on the existing harness against this part
  • Confirm the fault lies in the harness rather than the valve actuator or the control board
