What it is

The condensate trap hose is a Worcester Bosch spare that forms part of the condensate removal path on Greenstar ErP system boilers. Condensate forms as flue gases cool, and the trap collects this liquid so it can be routed safely out of the appliance. The hose carries that trapped water from the trap towards the discharge pipe, which is typically plastic to withstand the mild acidity created when CO2 from combustion dissolves in the condensate.

Signs this part needs replacing

  • Water or condensate collecting around the trap or beneath the boiler
  • Visible cracking, splitting or hardening of the hose material
  • Damp staining or corrosion on nearby casing and components
  • Boiler locking out or showing a condensate-related fault code
  • Restricted flow through the hose caused by trapped debris or scale
