What it is

This is Ariston's printed circuit board, part number 950331, referenced by the manufacturer as "Gove 3-FFI". It is the boiler's central control, monitoring the thermostats, sensors and switches, and enforcing the safety functions that shut the boiler down if a fault is detected.

Signs this part needs replacing

  • Boiler will not respond to controls or displays no activity
  • Intermittent lockouts with no clear fault pattern
  • Boiler fails to ignite despite other components testing correctly
  • Display or indicator lights behaving erratically

Before you order

  • Confirm the part number printed on your existing board matches 950331
  • Check whether your boiler runs on natural gas or LPG
  • Isolate electrical power before removing the old board
  • Have the work carried out by a Gas Safe registered engineer
