What it is

The main printed circuit board for the Ariston Genus ONE Net range. It is the control board that runs the boiler's operating sequence, managing ignition, fan and pump output, temperature regulation and fault signalling to the display. This listing covers part number 65116545-03, which the supplier notes as replaced by 65116545-04 and 65116545-05.

Signs this part needs replacing

  • The boiler fails to fire, or repeatedly drops into lockout
  • No response to a heating or hot water demand from the controls
  • Display blank, frozen, or showing persistent fault codes
  • Fan or pump not running when the boiler calls for them
  • Intermittent running, unexplained resets, or erratic temperature control

Before you order

  • Confirm the appliance model and serial number from the data plate
  • Compare the printed number on the existing board against 65116545-03 and the replacement chain noted above
  • Note the boiler's GC number where one is shown, so the correct variant is matched
  • Any work inside the appliance casing should be carried out by a competent person
