What it is

The Ariston 65105587 is a rectifier diode supplied as a spare part for Ariston gas boilers. It is a small electronic component used within the appliance's control circuitry. It is listed by the manufacturer under gas boiler spares.

Signs this part needs replacing

  • The boiler fails to detect or hold a flame and locks out
  • Repeated lockouts or ignition faults traced to the rectification circuit
  • Intermittent or erratic flame sensing during operation
  • Continuity testing shows the diode open circuit or passing current in both directions
  • Visible burning, cracking or heat damage to the diode body

Before you order

  • Confirm the appliance model and edition match the fitment list above
  • Check the fault has been traced to the diode rather than another component in the circuit
  • Isolate the boiler from the electrical supply before removing or fitting any electronic part
  • Verify the part number 65105587 against the manufacturer's parts list for your appliance
