PART 12: TROUBLESHOOTING
(CONTINUED)
Fault Code F00
WATER HIGH TEMP F00
PUMP ON
Description:
This display indicates if the water in the boiler has
overheated. This code indicates a serious safety
issue and the boiler will not restart until it cools
down sufficiently and a technician repairs the
cause of the overheating and pushes the RESET
button on the display. This is a serious situation
and is indicated by the red light on the display
illuminating and the word LOCKOUT flashing on
the display. During this lockout fault, the pump
will be on as indicated on the second line of the
display in an effort to cool the boiler down.
Remedy:
1. Check circulator pump operation
2. If the circulator pump is running, be sure that
there is water in the system and that the water
is moving through the system as intended. Be
sure that all correct ball valves and or zone
valves are open or closed as intended.
3. Observe the temperature/pressure gauge. If
the water is not too hot and this message is
displayed, check the wiring to the water ECO
sensor and repair if necessary. If the wiring is
ok and this code is still present and the water
is not excessively hot, replace the ECO sensor.
Fault Code F01
FLUE TEMP/WAT LV
PUMP ON
F01
Description:
This display indicates that the flue temperature
limit switch of the boiler has tripped or that the
water level in the boiler is low (The will only
occur if the optional UL353 LWCO is installed).
This code indicates a serious safety issue. The
boiler will not restart until the flue cools down
sufficiently or the water level is restored. A tech-
nician must repair the cause of the problem and
push the RESET button on both the low water
cut-off control box and the display. This situa-
tion is indicated by the red light on the display
and the word LOCKOUT flashing on the display.
During this lockout fault, the pump will be on as
indicated on the second line of the display.
Remedy:
1. If the boiler has a UL353 LWCO, check to see
if the red LED on the LWCO control box is
illuminated. If so, correct the low water con-
dition and press the reset button on the
LWCO control box to reset the LWCO. The
LED should change to green. Press the reset
button on the front panel of the boiler to
reset the boiler control.
2. Check the flue for obstructions or any sign of
damage especially signs of excessive heat.
Repair as necessary. Push the red reset but-
ton on flue temperature switch located on
the flue inside the rear access door of the
boiler. NOTE: The switch temperature must
be less than 90°F to reset. Press the reset
button on the display. Run the boiler and
check the flue temperature by using both an
external thermometer in the flue pipe and
the flue temperature display in the status
screens. If the flue temperature is within
specs and the switch trips, replace the
switch. If the flue temperature is excessive,
check and adjust combustion controls on the
boiler. If the problem persists, inspect the
target wall in the combustion chamber and
replace it if cracked or damaged.
Fault Code F02
SUPPLY SENSOR
PUMP ON
F02
Description:
This display indicates that the supply tempera-
ture sensor of the boiler has failed. This code
indicates a serious safety issue and the boiler
will not restart until the sensor is replaced by a
technician and he pushes the RESET button on
the display. This situation is indicated by the red
light on the display and the word LOCKOUT
flashing on the display. During this lockout fault,
the pump will be on as indicated on the second
line of the display.
Remedy:
1. Check the electrical connection to the ther-
mistor on the outlet manifold. Verify 5 VDC
by checking in Molex Connector. If there is
no 5 VDC, check the harness. If harness is
OK, replace control. NOTE: The boiler will
reset automatically. Verify thermistor values
by referencing chart in this manual.
2. Replace thermistor if necessary.
