Troubleshooting
Before you call for service....
Save time and money! Review the chart below first and you may not need to call for service.
CAUTION For your safety, DO NOT attempt repair of electrical wiring, controls, heating elements or other
safety devices. Refer repairs to qualified service personnel.
Problem Possible Causes What To do
OPERATION AND PERFORMANCE
Not enough or no hot
water
Water temperature may
be set too low • See the Water Temperature Adjustment and Water Heater
Capacity sections. (Pages 4 and 6)
Cold water inlet
temperature may be
colder during the winter
months
• This is normal. The colder inlet water takes longer to heat.
• Consider increasing the set temperature as described in
the Water Temperature Adjustment section.
Leaking or open hot
water faucets • Make sure all faucets are closed.
Long runs of exposed
pipe, or hot water piping
on outside wall
• Insulate piping.
Dip tube damaged • Contact your local installer, plumbing contractor, or
previously agreed upon service agency.
A fuse is blown, circuit
breaker tripped, or
electric service to your
home may be interrupted
• Replace fuse or reset circuit breaker.
• Contact the local electric utility.
Inadequate wiring • See the Installation Instructions.
Manual reset high limit
(ECO) • See the Safety Controls section, see page 5.
Water Connections to
unit reversed • Correct piping connections.
Recirculating System
Interference (if installed) • Check flow rate is not set too high.
• Insulate piping
Water is too hot Water temperature is set
too high • See the Water Temperature Adjustment section.
Thermostat has failed • Contact your local installer, plumbing contractor, or
previously agreed upon service agency.
OTHER
Rumbling noise Water conditions in your
home caused a buildup of
scale or mineral deposits on
the heating elements
• Remove and clean the heating elements. This should only be
done by a qualified service person or plumbing contractor.
Water dripping down the
outside of the heater
Hot/Cold water connections
or other parts have loosened • Tighten the loose connections. This should only be done by a
qualified service person or plumbing contractor.
Relief valve producing
popping sound or
draining
Pressure buildup caused
by thermal expansion to a
closed system
• This is an unacceptable condition and must be corrected. See
Thermal Expansion section on page 12. Do not plug the relief
valve outlet. Contact a plumbing contractor to correct this.
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.
Go to GEAppliances.com/waterheater for information on
purchasing this replacement anode rod. A qualified servicer or
plumber should do this replacement. Use of a non-GE Appliances
approved anode rod, or operating the water heater without a GE
Appliances approved anode rod will VOID the warranty.
• In certain cases, increasing the tank temperature to 140°F (60°C)
can reduce this odor issue. Reference the Water Temperature
Adjustment section of the Important Safety Information of this
manual for procedure and dangers of scalding water. Installation of
temperature limiting valves can be used to reduce risk of scalding.
