What it is

The Sime 6186588 is an ionisation lead measuring 800 mm, used in Sime gas boilers. It links the ionisation electrode to the boiler's flame sensing circuit, allowing the control board to confirm a flame is present during and after ignition.

Signs this part needs replacing

  • Boiler locks out or fails to detect flame after the burner has lit
  • Repeated flame failure faults logged or shown on the control panel
  • Burner lights then cuts out shortly afterwards, with intermittent ignition
  • Visible scorching, cracking or brittleness on the lead or its insulation
  • Loose, corroded or heat-damaged connector at the electrode or board end

Before you order

  • Confirm your boiler model against the fit list above
  • Check the existing lead length and routing to ensure 800 mm is suitable
  • Inspect the ionisation electrode and its connector for wear before replacing the lead alone
  • Have the appliance model number and, where possible, the existing part number to hand
