What it is

The Vokera by-pass spring is a small internal component fitted within the boiler's by-pass assembly, part number 0555. It sits in the heating circuit of a range of Vokera gas boilers, where the by-pass regulates flow through the primary circuit as system resistance changes. It is a service part intended for installation by a competent heating engineer.

Signs this part needs replacing

  • Poor or erratic flow through the boiler's by-pass assembly
  • Overheating or excessive temperature rise across the primary circuit
  • Noise from the by-pass area during operation
  • Loss of stable differential pressure as system resistance changes
  • Visible damage, distortion or corrosion on the spring when the assembly is inspected

Before you order

  • Confirm the boiler model and GC number against the fit list above
  • Check the by-pass assembly on the appliance to confirm the spring is the failed component
  • Have the manufacturer's parts list to hand to verify the part number 0555 for your appliance
  • Isolate the appliance and follow the manufacturer's instructions before any work
