What it is

The Sime ionisation lead, part 6186596, is a 950 mm lead that connects the ionisation electrode to the boiler control circuit. It is used on Sime DEWY and Planet DEWY gas boilers. The lead carries the flame detection signal, allowing the boiler to prove ignition and continue operating safely.

Signs this part needs replacing

  • Boiler locks out or fails to detect flame after the ignition sequence.
  • Repeated flame failure or ignition lockout faults.
  • Intermittent shutdowns during a demand for heat or hot water.
  • Visible damage, corrosion or looseness at the lead terminals or insulation.

Before you order

  • Check the appliance model and product code against the fits list above.
  • Confirm the existing lead length and connector arrangement match the 950 mm lead.
  • Inspect the ionisation electrode and its connector for damage or contamination.
  • Have the boiler model details available to confirm compatibility.
