What it is

The Ariston 65115792 is a low pressure switch used on Ariston gas boilers. It monitors pressure within the appliance's hydraulic circuit and signals the control board when pressure falls outside the required range. It is listed under gas boiler spares in the switches category.

Signs this part needs replacing

  • Boiler fails to fire or drops into lockout with a low pressure fault indicated
  • Heating or hot water runs intermittently, cutting out as pressure is sensed incorrectly
  • Boiler will not run even though the system pressure gauge reads within range
  • Repeated lockouts that clear temporarily after a reset
  • No response from the boiler when pressure is correct and other safety devices test fine

Before you order

  • Confirm your boiler model against the fit list above, as the same part number covers a wide Ariston range
  • Check the GC number on your appliance data badge where one is listed
  • Compare the part number on the existing switch with 65115792 before removing it
  • Confirm whether your appliance is a combi, system or open flue variant, as fitment differs across the range
