Descaling 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
the heating
either chemically or manually:
element
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 (N fig. 5/2) helps protect the tank against corrosion. Depending on the
the anode 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".
rod
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.

4. Unscrew and remove the two phillips screws holding the thermostat onto the tank.
5. Install new thermostat and re-attach wiring and screws.
Resetting
Occasionally, the high temperature limit shut off device may trip the reset. This occurs
when water temperature exceeds 190° F. The shut off device may also trigger from a

power outage or electrical storm.
Switch
To reach the thermostat:
1. Disconnect power cord and remove the front cover. Firmly press reset button (B
Fig. 4) with the tip of a ball point pen or similar object. A click indicates the reset
was tripped. Reconnect power.
2. IMPORTANT: Check the operation of the thermostat, turn temperature dial from high
to low, if the red light does not go off on low setting, turn off power supply and call
a service person to replace the thermostat.
3. If the system works, place dial setting to desired setting. Note: a lower setting is
more economical and reduces the risk of scalding. Replace cover plate.
CAUTION: Call a technician if the high limit needs to be reset frequently.
