What it is

The Vokera by-pass spring, part number 8436, is a small component used in the hydraulic section of Vokera Excell gas boilers. It sits within the boiler's by-pass assembly, which regulates water flow through the appliance as demand changes. It is a service part typically replaced during hydraulic repair work.

Signs this part needs replacing

  • Boiler short-cycling or failing to hold a steady temperature
  • Poor temperature control on hot water or heating
  • Whistling, humming or vibration from the hydraulic section
  • Overheating or lockout during low-demand operation

Before you order

  • Confirm your boiler model against the fit list above.
  • Identify whether your Excell boiler has old or new hydraulics, as the fit list distinguishes between these variants.
  • Check the part number 8436 against the manufacturer's parts list for your appliance.
