ARISTON Magnesium Anode M4 Ø16×210 mm, 30 L, 570241

ARISTON 570241 is a magnesium sacrificial anode for electric water heaters, designed to protect the tank against electrochemical corrosion. During operation, the magnesium anode gradually wears away, taking the corrosive effect upon itself and helping protect the metal water-heater tank.

The anode has a diameter of 16 mm, a length of 210 mm and an M4 mounting thread. These specifications correspond to the original ARISTON spare-part number 570241.

This magnesium anode is primarily intended for ARISTON SG, PRO and TI series 30-litre water heaters. Before ordering, it is recommended to verify the exact heater model and the dimensions of the existing anode mounting.

A magnesium anode is a consumable water-heater component. Its wear rate depends on water chemistry, hardness, operating temperature and frequency of water-heater use, therefore the condition of the anode should be checked periodically.

Timely replacement of a worn anode helps reduce the risk of tank corrosion and maintain effective water-heater protection. During servicing, it is also advisable to inspect the heating element, gasket and internal surface of the tank.

ARISTON service documentation lists 65104164 as the replacement code for part 570241, retaining the same basic specification of Ø16 × 210 mm, M4. When selecting a replacement part, both the part number and the anode dimensions and mounting thread should be checked.
