Possible Causes

CAUTION:
For your safety, DO NOT attempt repair of electrical wiring, controls, heating elements or other
safety devices. Refer repairs to qualified service personnel.
A fan is used to move air through
the system
Room is not vented properly or is
too small
Heat is removed from the air to
heat the water
Condensate drain is clogged
Hot/Cold water connections are
not tightened
Water temperature may be set
too low
Hot water usage pattern exceeds
the capability of the water heater in
current mode
Leaking or open hot water faucets
Long runs of exposed pipe, or hot
water piping on outside wall
Not enough clearance to allow air
to circulate for the heater pump
Room size is not appropriate for
water heater
Inadequate wiring
Manual reset limit (TCO)
Water connections to unit re-
versed
Water temperature is set too high
Electric control has failed
Water conditions in your home
caused a buildup of scale or
mineral deposits on the heating
elements
The water heater has not been
filled with water before power-
ing up. Powering up the heater
without water will damage the
electric heaters. The water heater
warranty does not cover damage
or failure resulting from operation
with an empty or partially empty
tank.
The anode rod is not connected
properly and the water heater may
not be protected from corrosion.
There is an issue with the heat
pump system.
There is an issue with the water
heater that requires immediate
attention.
Certain water supplies with high
sulphate content will react with
the anode rod that is present in
all water heaters for corrosion
protection of the tank
What To do
• Some amount of fan sound is normal. If you hear an abnormal sound or the sound
level seems unusually loud, then contact service.
• If the room is smaller than 10' x 10' x 7' (3m x 3m x 2.1m) then it must have a lou-
vered door or other means to allow air exchange with surrounding rooms.
• This is normal.
• Clear out any debris in the drain port on the unit.
• Tighten the inlet and outlet pipe connections.
• See About the Water Temperature Setting section.
• Change to different mode.
• Wait for the water heater to recover after an abnormal demand.
• Make sure all faucets are closed.
• Insulate piping.
• Make sure unit is 7" away from the wall and has 8" clearance above the air filter.
• If room size is less than 10' x 10' x 7' (700 cu. ft.), install louvered door or similar
ventilation.
• See the Installation Instruction section.
• See the Safety Control section, see page 4.
• Correct piping connections.
• See About the Water Temperature Setting section.
• Call for service.
• Remove and clean the heating elements. This should only be done by a qualified
service personnel.
• Fill the tank completely with water. Press ENTER to stop the alarm and then cycle
power when the tank has been filled.
• If the unit has been confirmed to be filled with water, and an F11 code is expe-
rienced, it is possible that the code may be a false indicator due to certain unique
environment conditions encountered during the start up. If the unit is full of water,
turn the breaker off for about 10 minutes to allow the water temperature to
stabilize, then turn the breaker back on. If the F11 code persists, schedule service.
• Check that the tank is filled completely with water.
• If the tank is full of water and the F17 code persists, contact
service.
• The unit will automatically switch to another available mode to ensure you contin-
ue to have hot water. Contact service immediately and give them the codes listed on
the display screen.
• The heater may switch to another available heating mode. Contact service imme-
diately. To stop the beeping noise (unless error code F2, F11, F17 or bAd linE) press
either the UP or DOWN arrow button and the alarm will stop and the display will go
back to normal (set temperature).
• 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. A qualified servicer or plumber
should do this replacement.
