Table of Error Codes
1
Check gas, water and electrical supplies are available at the
boiler
.
2
Electrical supply = 120V ~60 HZ
3
The preferred minimum gas pressure is 3.5” wc for Natural
gas and 10” for LPG
4
Perform electrical system checks, i.e. Ground Continuity,
Resistance to Ground, Short Circuit and Polarity with a
suitable meter.
NOTE: These checks must be repeated after any servicing
or fault finding.
5
Ensure all external controls are calling for heat and check
all external and internal fuses. Before any servicing or
replacement of parts, ensure the gas and electrical supplies
are isolated.
1 If a fault occurs on the boiler an error code may show on the
fascia display:
E
20,
E
28,
E
40,
E
50,
E
160,
E
321, and
E
431 -
Indicate
possible faulty components.
E
53 -
Indicates possible obstruction in the flue duct.
E
55 -
Indicates the PCB is not setting/calibrated.
E
71,
E
72,
E
78 and
E
92 -
Indicates possible wrong
calibration, a new calibration is needed.
E
92
- Indicates possible flue recirculation in the flue duct.
E
83......87 - Shows possible error of communication with
thermostat. (Go to section P, page 47)
E
110 -
Shows overheat of primary.
E
117 - is displayed when the primary water pressure is
more than 43 psi.
E
118 - is displayed when the primary water pressure is less
than 7.25 psi.
E
125
-
is displayed in either of two (2) situations:
a)
If within a time between 15...30 seconds of the burner
lighting the boiler temperature has not changed by 2°F.
b)
If within 10 minutes of the burner lighting the boiler
temperature twice exceeds the selected temperature by
80°F.
In these instances poor primary circulation is indicated.
E
128 - is displayed if there has been a flame failure during
normal burner operation.
E
133
,
E
134
,
E
135
-
Indicate the gas supply has been
interrupted, ignition has failed or flame has not been
detected.
2
Pressing the ‘RESET’ button for 1-3 seconds when:
E
110,
E
125,
E
133,
E
134,
E
135,
E
09,
E
15,
E
128 and
E
384 - are displayed it is possible to relight the boiler.
3
If this does not have an effect, or error codes are displayed
regularly further investigation is required.
