What it is

The Vaillant compressor wiring harness, part number 0020210694, is the wiring loom that connects the compressor to the control and power side of the appliance. It is specified for 5-8kW and 11kW 400V compressor circuits. It is used across the Vaillant VWF 57/4 and VWF 87/4 230V heat pump range, including Flexotherm variants.

Signs this part needs replacing

  • Compressor fails to start, or starts and cuts out intermittently with no other fault identified
  • Visible heat damage, scorching or brittleness at the harness connectors
  • Chafed, cracked or exposed insulation along the length of the loom
  • Loose, corroded or discoloured terminals at the compressor plug
  • Continuity faults or open circuits traced through the harness wiring

Before you order

  • Confirm your appliance model and variant against the fit list above
  • Check the voltage and output rating of your unit, as the models listed here are 230V
  • Inspect the existing harness for its part number and connector layout before removal
  • Isolate the power supply and follow the manufacturer's instructions for compressor access
