The heater is beeping,
the anode light is on (on
some models), and the
display says F16
The anode rod is approach-
ing end of life and it is
recommended to replace it
in order to continue to offer
protection from corrosion.
• Call for service or follow the instructions on how to replace the
anode rod on page 12. Ensure that the anode depletion sensing
anode rod or other GE Appliances approved anode rod is installed.
Installation of an unapproved anode rod will VOID the warranty.

Hot water has a rotten
egg or sulfur smell
Certain water supplies with
high sulfate content will react
with the anode rod that is
present in all water heaters
for corrosion protection of
the tank
• The odor can be reduced or eliminated in most water heaters
by replacing the anode rod with less-active material rod. In some
cases, an added step of chlorinating the water heater and all hot
water lines may be necessary, contact your local water professional
or plumber for options and instructions. Call 1.888.4GE.HEWH
