Ariston Ceramic Resistance 4500W 323507

The Ariston 323507 is a ceramic resistance heating element rated at 4500W with an overall length of 770mm. It is the immersion-type heating element used in Ariston Perfo and STYX Perfo storage water heaters, where it transfers heat directly to the stored water. The ceramic construction is suited to the operating temperatures and water conditions found in these appliances.

• The appliance runs but the water does not heat, or heats far more slowly than it should.
• The element circuit trips the MCB or RCD when the heater is powered up.
• Visible cracking, blistering or scaling on the ceramic element body.
• Discolouration or heat damage around the element terminals or connections.
• Continuity or resistance testing shows an open circuit or a reading outside the expected value for the element.

• Confirm the appliance model and edition against the fit list above, as fitment is model-specific.
• Check that the existing element is rated 4500W and measures 770mm in length before ordering.
• Isolate the electrical supply and drain the appliance as required before removing the old element.
• Check how many elements the appliance uses so the correct quantity is ordered.
