The most likely reasons for an electric wa-
ter heater to produce NO hot water are:
• No electric power—a common prob-
lem with new installaons
• Burned out upper element (Dry
Fired) — a common problem with
new installaons
• Tripped Energy Cut O (red buon
on upper thermostat)
• The water heater’s inlet and outlet
connecons are reversed (usually
only in new installaons)
• Broken upper thermostat (or wiring)
• A leak in the hot water side of the
plumbing system that exceeds the
water heater’s heang capacity and
makes it appear that the water heater
is producing lile to no hot water

 No hot
water is oen caused by a
problem with the home’s electrical
wiring or circuit breakers. You’ll need a
non-contact circuit tester. Follow these
guidelines:
• Locate the water heater’s circuit
breaker and turn it o (or remove the
circuit’s fuses).
• Locate the electrical juncon box on
top of the water heater and remove
the cover.
• Idenfy the two power wires. The
power wires are usually black/black
or black/red—the green or copper
wire is the ground wire.
• Turn the circuit breaker back on
(or install the fuses) and check the
power on both incoming power wires
using a non-contact circuit tester.
• Turn the power o and replace the
cover on the electrical juncon box.
If the water heater is not geng
power, contact a qualied person to
have your home’s wiring or circuit
breakers checked.

 If the water heater is
geng electrical power, check
to see if the upper heang element has
burned out. If the upper element is
burned out, you’ll have no hot water.
To check the upper element, you’ll
need a mulmeter capable of reading
resistance.
• Turn the power OFF at the circuit
breaker or remove fuses.
• Remove the upper access panel.
• Remove the insulaon to access the
upper thermostat and heang ele-
ment.

heater, a burned out upper heang
element is almost always caused by
turning the power on before the tank
was completely full of water (Dry Fire).

are clean and ght. Next, check the
following:
Use a non-contact circuit tester to check for
electrical power.
Use a mulmeter to check the resistance of the
upper heang element.
