What it is

The Potterton 5106568 is a printed circuit board that provides the electronic control function on the Suprima 120 L gas boiler. It manages the boiler's operating sequence, monitoring and firing logic. The board is supplied as a service part for the Suprima 120 L appliance.

Signs this part needs replacing

  • Boiler fails to fire or run through its start sequence
  • Repeated lockouts that cannot be cleared by resetting
  • No heating or hot water despite demand from the controls
  • Erratic or intermittent boiler behaviour with no obvious mechanical cause
  • Visible damage, scorching or moisture tracking on the board itself

Before you order

  • Confirm the appliance is a Potterton Suprima 120 L and check the GC number on the boiler data badge
  • Check the part number printed on the existing control board against 5106568
  • Inspect the board and its plug connections for damage before ordering, as faults elsewhere can mimic control board failure
