What it is

The Vaillant 0020210698 is a low pressure sensor used in Vaillant VWF and Flexotherm VWF heat pump appliances. It monitors low side pressure within the refrigerant circuit and provides that reading to the appliance control. The sensor forms part of the appliance's pressure monitoring and protection system.

Signs this part needs replacing

  • The appliance reports a low pressure fault or locks out on pressure monitoring
  • The heat pump fails to start or shuts down shortly after starting
  • Pressure readings at the control are absent, erratic or implausible
  • Intermittent operation with repeated pressure-related cut-outs
  • The sensor or its connection shows signs of damage, contamination or corrosion

Before you order

  • Confirm your appliance model against the fit list above
  • Check the part number on the existing sensor matches 0020210698
  • Verify the fault is traced to the sensor rather than the refrigerant charge or circuit
  • Confirm whether your appliance is a VWF or Flexotherm VWF variant before ordering
