What it is

The Ariston 691694 is a thermostat used in Ariston SE 10R and ST 10R appliances. It controls the temperature at which the appliance operates by switching the heat source in response to the sensed water temperature. It is supplied as a single component for service replacement.

Signs this part needs replacing

  • Domestic hot water runs cold or only lukewarm regardless of the setting
  • Water temperature is noticeably higher or lower than the dial position suggests
  • Temperature swings between hot and cold during a single draw-off
  • The appliance fails to switch off at the set temperature and overheats
  • No continuity through the thermostat when tested across its terminals

Before you order

  • Confirm your appliance model and edition match one of the fitments listed above
  • Check the markings on the existing thermostat against part number 691694
  • Inspect the wiring and connections before assuming the thermostat is at fault
  • Confirm whether the fault lies with the thermostat or the appliance's other controls
