What it is

The Ariston 573452 is an air pressure switch used on Ariston gas boilers. It monitors the pressure produced by the fan and confirms that combustion air is moving before the boiler is allowed to fire. It is listed as a gas boiler spare for the Ariston DIA 24 MFFI CE.

Signs this part needs replacing

  • The boiler locks out on ignition with the fan running but no flame established.
  • Repeated lockouts that clear on reset and then return.
  • The boiler fails to fire for heating or hot water, or fires intermittently.
  • A fault code or diagnostic indication pointing to the air pressure switch or fan proving circuit.
  • The switch does not change state when the fan is running, or the sensing tube connection is sound but the boiler still will not prove air flow.

Before you order

  • Confirm the appliance model is the Ariston DIA 24 MFFI CE.
  • Check the part number 573452 matches the switch being removed.
  • Inspect the sensing tubes and their connections for blockage, splitting or loose fit before condemning the switch.
  • Verify the fan is running and producing pressure, as a failed fan can give the same symptoms.
