Troubleshooting
Guide
Operational
Conditions
SMELLY
WATER
In each water heater there is installed at least one anode rod (see
parts section) for corrosion
protection
of the tank. Certain
water
conditions
will cause a reaction between this rod and the water.
The most common
complaint
associated with the anode rod is
one of a "rotten egg smell". This odor is derived from hydrogen
sulfide gas dissolved in the water. The smell is the result of four
factors which must all be present for the odor to develop:
a. a concentration
of sulfate in the supply water.
b. little or no dissolved oxygen in the water.
c. a sulfate reducing
bacteria
within
the water heater.
(This
harmless bacteria is non-toxic to humans.)
d. an excess of active hydrogen
in the tank. This is caused by
the corrosion
protective action of the anode.
Smelly water may be eliminated or reduced in some water heater
models by replacing the anode(s) with one of less active material,
and then chlorinating the water heater tank and all hot water
lines. Contact the local Sears Service Center for further informa-
tion concerning an Anode Replacement Kit #9001453 and this
Chlorination Treatment.
If the smelly water persists after the anode replacement
and chlo-
rination
treatment,
we can only suggest that continuous
chlori-
nation
and filtering
conditioning
equipment
be considered
to
eliminate
the waterproblem.
RUMBLING
NOISE
In some water areas, scale or mineral deposits will build up on
your heating elements. This buildup will cause a rumbling noise.
Follow "Element Cleaning/Replacement"
instructions to clean
and replace the elements.
HIGH
TEMPERATURE
SHUT
OFF
SYSTEM
The water heater has a high limit shut off"system with a reset
button located on the thermostat.
Follow the resetting
instructions
which
refer to the high limit
behind the access panel.
NOTE: If your water heater
is connected
to an "OFF PEAK"
clock,
and
uses the "3 wire
lead"
wiring
diagram
in the
"W'tring
Diagram"
section,
then the water heater
will have a
hi-limit
on both
the upper
and
lower
thermostats.
Follow
the instructions
to reset the hi-limit
behind
the upper
and
lower access panels.
• Before beginning, turn "OFF" electrical power supply to the
water heater.
Do not remove the anode leaving the tank unprotected. By
doing so, all warranty on the water heater tank is voided.
"AIR"
IN HOT
WATER
FAUCETS
AWARNING
HYDROGEN GAS: Hydrogen gas can be produced in a
hot water system that has not been used for a long peri-
od of time (generally two weeks or more). Hydrogen gas
is extremely flammable and explosive. To prevent the
possibility of injury under these conditions, we recom-
mend the hot water faucet be opened for several min-
utes at the kitchen sink before any electrical appliances
which are connected to the hot water system are used
(such as a dishwasher or washing machine). If hydrogen
gas is present, there will probably be an unusual sound
similar to air escapingthrough the pipe as the hot water
faucet is opened. There must be no smoking or open
flame near the faucet at the time it is open.
AWARNING
HAZARD OF ELECTRICAL SHOCK! Before removing
any access panels or servicing the water heater, make
sure the electrical supply to the water heater is turned
"OFF". Failure to do this could result in DEATH, SERI-
OUS BODILY INJURY,OR PROPERTY DAMAGE.
