13.1 Error Messages And Resetting The Boiler
13 - TROUBLE SHOOTING
Error Description
Operation
09
Gas valve connection fault
Check cable PCB/gas valve and gas valve plug
10
Outdoor sensor fault
Check sensor and cable
15
Gas valve command fault
Verify all cables. Replace PCB.
20
Central Heating NTC sensor fault
Check sensor and cable
28
Flue NTC heat exchanger sensor fault
Check sensor and cable
40
Return NTC sensor fault
Check sensor and cable
50
Domestic Hot Water NTC sensor fault
Check sensor and cable
53
Obstruction in flue pipe, Recirculation, Out of
Calibration, Poor gas quality
Check for obstruction in flue pipe. Check gas pressure, check
gas orifice. Check for recirculation, recalibrate, check gas
quality.
55
PCB not programmed
Follow instructions provided with control board replacement kit,
call technical service for assistance.
E72/E92
Combustion test alarm during commissioning /
calibration
Check flame sensor, check for obstruction in flue pipe, check
for recirculation, check gas pressure, check gas orifice, check
gas quality. Perform automatic calibration function and manual
calibration function if necessary.
78
Minimum gas valve IMOD current
Check gas supply pressure
Check the correct position and integrity of the sensing electrode
Check and clean the igniter and sensing electrode if necessary
Check flue recirculation
Check Combustion is within specifications in IOM
Auto calibrate, manual calibrate if necessary
Replace components if all else fails
79
Maximum gas valve IMOD current
E83
OT Communication Failure
Check OT connection, remove power, reconnect OT
connections, if problem persists replace service key.
84-85
86-87
Communication problem between boiler board and
control unit
Probable short circuit on wiring.
Check cable between control unit and boiler
109
Pre-circulation alarm (temporary fault)
Check correct circulation of water and pump. Check supply and
return wiring is correct.
110
Safety thermostat tripped
due to over temperature
(pump probably blocked or air in heating
circuit)
Check safety thermostat and cable; check correct circulation of
water and pump
118
Hydraulic pressure too low.
Refill heating system by opening cold water tap
117
Hydraulic pressure too high.
Relieve pressure via relief valve or drain. Ensure water feed is
operating correctly.
125
No circulation of water
(control performed via temperature sensor).
Check correct circulation of water and pump.
Check correct connection of NTC sensor on pipe
128
Loss of flame 8 consecutive times after flame
proving stage.
Check sensing electrode and cable, flue recirculation,
electrical continuity between burner and ground, gas
pressure, gas orifice. Perform automatic calibration and
manual calibration function if necessary.
130
NTC flue sensor tripped due to over temperature
Check thermostat, correct circulation of water and pump.
Check status of primary exchanger.
131
Thermo fuse tripped due to over temperature or
wire harness disconnected from thermo fuse, off
the board, or wire harness may be cut.
Check thermo fuse, correct circulation of water and pump.
Check status of primary exchanger. Replace heat exchanger.
Verify wire harness installation and continuity.
133
Ignition failure
Check correct operation of condensate trap. Check
sensing electrode, spark electrode and cable. Check flue
recirculation, electrical continuity between burner and ground.
Check gas orifice and gas pressure. Perform automatic
calibration and manual calibration function if necessary.
134
Gas supply valve blocked
Check gas pressure, sensing electrode, spark electrode and
cable, replace PCB if it necessary.
