What To do
•
See About the Water Temperature Setting section.
•
Call for service.
• Remove and clean the heating elements. This should only
be done by a qulified service personnel.
•
This is an unacceptable condition and must be corrected.
See Thermal Expansion Information on page 14.
Do not plug the relief valve outlet.
Contact a plumbing contractor to correct this.
•
Fill the tank completely with water. Apply power to unit
after the tank has been filled. Press ENTER to stop the
alarm.
•
If the unit has been confirmed to be filled with water, and
an F11 code is experienced , 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
the water temperature to stabilize, then turn the breaker
back on. If the F11 code persists, schedule service.
•
Follow the instructions on how to remove and clean the
filter on page 11.
• Repeated dirty filter alarms that do not resolve by cleaning the
filter may be an indication of a fan failure. Contact service.
•
The unit will automatically switch to another available
mode to ensure you continue 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 immediately. To stop the beeping noise
(unless error code F2, F11 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).
• Turn off power to water heater (generally at the breaker
panel). Then read "Electrical Connections" section of
Installation Instructions, see page 16. Then, contact the
installer to verify electrical input to the water heater.
• 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.
• This is normal. Wait for the water heater to complete the self
test and begin normal operation.
•
Check mode of unit.
