Draining The Tank; Fault Indication And Error Codes - Kenmore Elite 153.331010 Use & Care Manual

• Disconnect the hoses joining the tank and the heat
engine (upper hose is water outlet and lower hose is
water inlet) at the heat engine fi ttings.
• Connect a length of hose (not provided) to each of the
fi ttings. (Note: A GHT (garden hose thread) to 3/4" NPT
adaptor may be required.)
5 gallon pail of virgin,
food grade, white
vinegar (or virgin,
food grade,
citric acid).

• Connect a pump to the hose running to the heat
engine water inlet (lower fi tting). We recommend a
submersible utility pump for the circulating pump. (Note:
If a submersible pump is not used, connect a hose from
the circulating pump to the cleaning solution.)
• Pour approximately 4 gallons (15 litres) of virgin, food
grade, white vinegar or citric acid into a 5 gallon or
greater pail.
• Place the "intake" and "output" hoses into the pail of
cleaning solution. If a submersible utility pump is used,
place the pump into the pail of cleaning solution.
• Plug in the circulating pump.
• Connect the electrical power to the water heater and
run the heat engine.
• Operate the heat engine to circulate the cleaning
solution through the system for at least 45 minutes.
(Note: Lower the temperature below 104°F (40°C) or to
vacation mode.) Warning: cleaning solution will become
hot very quickly.
• Disconnect electrical power to the water heater.
• Remove the pail of cleaning solution and replace it with
a pail of clean water.
• Rinse the cleaning solution from the water heater as
follows:
• Connect the electrical power to the water heater and
run the heat engine.
• Allow the clean water to fl ow through the heat engine
for 5 minutes.
• Disconnect electrical power to the water heater and
circulating pump.
• Disconnect hoses from heat engine and circulating
pump, draining the cleaning solution into the pail.
• Reconnect the original hoses to the heat engine.

• Remove the in-line fi lter at the cold water inlet and
clean out any residue. Assemble the fi lter back into the
unit.
• Open the shutoff valves on both the hot water and cold
water lines.
• Fill the tank with water.
• Connect the electrical power to the water heater.
• Restart water heater following lighting instructions.

DRAINING THE TANK

FAULT INDICATION AND ERROR CODES

A red fault LED (lighting a large red exclamation point)
should be present on the display panel if a fault condition
exists.
A history of the last 9 error codes along with the current
error code is stored in memory and can be accessed via
the diagnostic mode. If the current error code is zero, "E00"
shall be displayed (see Table 3).
Set the power switch to the "OFF" position.
OPEN a nearby hot water faucet and let the water run
until it is no longer hot.
CLOSE the cold water inlet valve to the water
heater.
Connect a hose to the drain valve and terminate to
an adequate drain.
OPEN the water heater drain valve to allow for tank
draining. NOTE: If the water heater is going to be
shut down and drained for an extended period,
the drain valve should be left open with hose
connected allowing water to terminate to an
adequate drain.
CLOSE the drain valve.
Follow instructions in the "Filling The Water Heater"
section.
Follow the lighting instructions on the label or see
"Lighting Instructions" in this manual to restart the
water heater.
