Anode Rod Maintenance and Service
Anode rods are designed and installed to protect and
extend the life of residential water storage tanks.
The anode rod must be removed from the water heater's
tank and inspected annually, and replaced when more
than 6" (15.2 cm) of core wire is exposed at either end of
the rod. *NOTE: Artificially softened water will cause the
anode rod to consume more rapidly.
The gas and cold water supply must be turned off before
servicing the anode rod.
NOTICE: Do not remove the anode rod from the water
heater's tank except for inspection and/or replacement,
as operation with the anode rod removed will shorten
the life of the glass-lined tank and will void warranty
coverage.
Some areas have water conditions that may cause
an odor to develop in the water heater. Special alloy
replacement rods are available to address this condition.
*NOTE: Failure to replace the anode rod when
consumed voids the warranty for the tank. Warranty
coverage for all other components remains intact
and is unaffected by this maintenance requirement.
The replacement anode rod and the inspection for
consumption are not covered by the warranty.
Inspecting the Anode Rod:
1. Turn off the water heater and drain 1-2 gallons of
water from the tank. (Refer to Draining the Tank, page
11.)
2. Remove the anode cap and foam insulation beneath
it with a flathead screwdriver. (Refer to illustration
below.)

3. Unscrew the anode rod using a 1 1/16" socket/wrench
and lift it out of the water heater.

4. Inspect the anode rod. If more than 6" of core wire is
exposed, the anode rod should be replaced. (Refer
to illustration below.) If the anode rod has not been
depleted, reinsert it into the water heater following
steps 2-6 below.
CAUTION
DO NOT touch the vent hood or vent
pipe located in front of the anode rod. These are
very hot and present a burn hazard.
Replace anode rod
if more than 6" of
core wire exposed
Installing the Anode Rod:
1. If a new anode rod is required, be sure to purchase the
same type. For further information, contact a qualified
service technician or GEA Customer Support at
GEAppliances.com/waterheater.
2. Apply pipe joint compound or pipe thread sealant tape to
the threads of the anode rod.
3. Insert the anode rod into the water heater and tighten
with a torque wrench to 50 +/- 5 ft-lbs. of torque.
4. Close the drain valve, turn on the water supply and open
a hot water faucet to remove any air trapped in the water
lines.
5. Check for any leaks and repair.
6. Ensure that the water heater is completely full before
relighting it. (Refer to Lighting Instructions, page 7.)
