What it is

The Worcester Bosch condensate siphon (Xi Low) is a condensate assembly used on Greenstar i ErP System boilers. It collects the condensate formed during combustion and passes it to the drain, holding a water seal that keeps flue gases within the condensate route rather than letting them escape. It is supplied as Worcester Bosch part 8716117083.

Signs this part needs replacing

  • Condensate or water collecting beneath the boiler or around the siphon body
  • Boiler locking out or shutting down on a condensate-related fault
  • Gurgling, bubbling or slow draining noises from the condensate route
  • Visible cracks, splits or distortion in the trap or siphon housing
  • Heavy scale, sludge or debris build-up causing repeated blockages
