Ecoflam Ionisation Probe 65320902

The Ecoflam ionisation probe 65320902 is a flame-sensing electrode fitted to the burner head of Ecoflam BLU series pressure-jet boilers. It sits in the flame path and returns a small ionisation current to the control box, confirming that combustion has been established and allowing the burner to run. The part is catalogued under the part number 65320902 alongside the listing codes D10X100, D6 4 and D3X65 90.

• The burner fires, then locks out after a short running period with no flame signal held.
• Repeated lockouts on start-up that are not cleared by resetting the control box.
• Nuisance lockouts that appear once the burner and probe are hot, but not from cold.
• The probe tip is heavily sooted, eroded or the ceramic insulator is cracked or discoloured.
• The boiler runs intermittently, cutting out and restarting without a thermostat or pressure fault.

• Confirm the appliance model from the data plate against the fit list above.
• Compare the probe dimensions and codes on the existing electrode with the listing codes before ordering.
• Inspect the burner electrode assembly and its gasket, and replace any worn sealing components at the same time.
• Check the control box fault history to confirm the fault is flame supervision rather than ignition or fuel supply.
