Descaling the heating element

Scale deposits can affect the heating capability of the element.

Heavy scale can even cause the element to burn out. The element can be descaled either chemically or manually:

A)Soak the element in white vinegar or other descaling solution. Once descaled, rinse well with fresh water, to which you should add some baking soda, OR

B)Once the element has dried up, use a soft brush (non metallic to prevent damaging the stainless steel sheath) on element. Brush the dried mineral off. Reinstall the element with gasket and make the wire connections.

C)Replace anode rod (N Fig. 5/2) if it is noticeably deteriorated or considerably shorter then seen in figure 5/2.

WARNING: make sure the tank has been refilled with water before restoring power.

REPLACEMENT OF PARTS

Changing the anode rod

The anode rod (N fig. 5/2) helps protect the tank against corrosion. Depending on the water condition, the magnesium anode rod may need to be changed every year or so. Galvanic and electrolytic corrosion can destroy a tank if the anode rod is “spent”. Rusty water is usually an indication of a “spent” anode rod. If rusty water is present, examine anode rod immediately. Rapid degradation of the anode rod (less than 1 year) may indicate the presence of galvanic corrosion due to “stray” direct current. In this case, it may be necessary to add a “grounding strap” from the Ariston tank to the copper plumbing.

1.Turn off the power supply and drain the heater (see Draining the Heater).

2.Remove heating element (see previous section).

3.Remove and replace the anode rod N Fig. 5/2.

4.Refill tank with water before restoring power.
