Remove the upper or lower
access panel on the water
heater, and then fold back the
insula on and remove the plas c
element/thermostat cover.

With the tank drained and
power off , remove the power
wires from the element you
intend to replace.
7
Remove the bad element
using an element wrench.
8
Make sure the new element is
the correct replacement by
referring to the water heater’s
data plate for voltage and wa age
informa on.
9
Clean the threads in the tank
opening with a rag. Insert the
new element equipped with a
rubber gasket. NOTE: Use a drop of hand
dishwashing liquid to lubricate the gasket
to help avoid damaging the gasket as it is
being  ghtened. Tighten with an
element wrench.
NOTICE: Do not turn power back on un l
the tank is completely full of water. For
complete instruc ons on fi lling the tank,
follow Step 8 in the Installa on sec on.
10
Refi ll the tank by opening the
cold water supply valve. Make
sure a hot water faucet is open
and the drain valve is closed. Allow the
hot water to run full for at least three
minutes to make sure the tank has all the
air removed and is completely full of
water. Failure to perform this step can
cause the upper hea ng element to burn
out. Once you are certain the tank is
completely full of water, close the hot
water faucet.

Check the newly installed
element for leaks. If a leak is
present,  ghten the element
un l the leak stops. If you cannot stop
the leak, drain the tank and remove the
element. Inspect the gasket for damage.
If the gasket is damaged, replace the
gasket and re-install the element.
12
Once the element is success-
fully installed and there are no
leaks, replace the power wires,
thermostat cover, insula on, and access
panel. Make sure all wire connec ons
are  ght. Replace the cover on the
electrical junc on box.

Restore power to the water
heater. It may take two hours
for the tank to heat up.
Replacing the Thermostat
WARNING! Working on an ener-
gized circuit can result in severe injury
or death from electrical shock. Turn
power off . Check wires with a non-con-
tact circuit tester to make sure power is
off . When you are fi nished, be sure all
covers are secured to reduce the risk of
fi re and electric shock.
To replace the thermostat, you’ll need
the following tools and supplies:
• A non-contact circuit tester. Always
turn power OFF
and check with a non-contact circuit
tester before working on the water
heater.
Figure 36 - Upper and Lower Thermostats
• A replacement thermostat (available
at Lowe’s® ). Note that the upper
and lower thermostats are different
(above). Some models only have one
thermostat.
• A business card to check the gap
between the thermostat and the tank
• Tape and a permanent marker to
mark the wires
• A flat blade and a Phillips screwdriver
Steps for Replacing the
Thermostat:
1
Turn the power OFF at the
circuit breaker or remove fuses.
NOTICE: It is not necessary to drain the
tank to replace a thermostat.
2
Open the electrical junc on box
on top of the water heater.
Using a non-contact circuit
tester, check the power wires to make
certain the power is OFF.
