What it is

The Vaillant 0020175834 is a fuse used in Vaillant Arotherm air source heat pump installations. It protects the appliance's electrical circuit by breaking the supply if current exceeds the rated value. It is a service component for the VWL 115/2 and VWL 155/2 A 230V models.

Signs this part needs replacing

  • The heat pump will not power up or run at all
  • The control panel or display stays blank with the supply confirmed live
  • The fuse shows a visibly blown element or darkened body
  • A replacement fuse blows again shortly after fitting, indicating a circuit fault

Before you order

  • Confirm the part number 0020175834 against the existing fuse or the appliance's parts list
  • Check the rating markings on the failed fuse match the replacement
  • Isolate the electrical supply before removing or fitting the fuse
  • Investigate the cause of the failure before restoring power, as a fuse blowing usually points to an underlying fault
