What it is

The 87161045540 is Worcester's flame sense lead for the Highflow 400 Electronic BF (appliance code 47-311-62). It carries the signal from the flame sensing electrode back to the control board, confirming to the boiler that the burner has lit successfully.

Signs this part needs replacing

  • Boiler ignites but then locks out shortly after, as if the flame isn't being detected
  • Intermittent lockouts on a flame-loss fault code
  • Visible damage, cracking or corrosion on the existing lead or its connector
  • Burner cycles on and off repeatedly rather than running steadily

Before you order

  • Match the part number 87161045540 printed on your existing lead
  • Confirm the boiler model and GC number, as this is an obsolete part for an older boiler range and stock may be limited
  • Isolate the electrical and gas supply before removing the old lead
  • Fitting must be carried out by a Gas Safe registered engineer
