12.8 Changing the anode rod

A magnesium anode is used to extend the life of the tank.
Permanent removal of this anode for any reason will void
the warranty.
Depending on conditions, the magnesium anode rod may
need to be changed approximately every two years. Galvanic
and electrolytic corrosion can destroy a tank with a spent
anode rod. Rusty water is usually an indicator of a spent
anode rod.
1. Unplug and drain the water heater (See 12.3,
"Draining the water heater", pg. 9).
2. Remove the cover (See 12.4, "Removing the cover",
pg. 9).
3. Remove the heating element (See 12.5, "Removing
the heating element", pg. 9).
4. Remove the anode rod from the dismounted heating
element holder by unscrewing.
5. Fit a new anode rod into the heating element
holder.
6. Refit all the wires and the heating element.
7. Refill the water heater with water and check for
leaks before connecting the power.
