CODE
CONDITION
POSSIBLE CAUSES
E 00
A flame signal was present when there should
be no flame.
• Defective gas valve - make sure inlet pressure is below maximum on rating plate
before replacing valve.
E 02
Flame failure after 5 tries to restart
• No gas pressure
• Gas pressure under minimum value shown on rating plate
• Gas line not completely purged of air
• Defective Electrode
• Loose burner ground connection
• Defective Ignition Cable
• Defective gas valve (check for 24 VDC at harness during trial for ignition before
replacing valve)
• Air-fuel mixture out of adjustment - consult factory
E 03
Gas valve error
• Loose or defective gas valve harness. Check electrical connections.
• Defective gas valve (check for 24 VDC at harness during trial for ignition before
replacing valve)
E 04
Power failure occurred after lockout
• Some other error on this list occurred and power to the boiler was then
interrupted. Reset control and see if hard lockout reoccurs.
E 05
E 06
E 07
E 11
Internal control failure
• Reset the control. If problem reoccurs, replace the MCBA.
E 12
Low water cut-off circuit open
• If yellow light on LWCO is on, system is low on water
• If neither yellow nor green light is on, check LWCO harness and check for
24VAC across AT140 transformer
E 13
E 14
E 15
E 16
E 17
Internal control failure
• Reset the control. If problem reoccurs, replace the MCBA.
E 18
MCBA supply sensor detected temperatures in
excess of 200°F for an extended period of time
• See possible causes for “b18” error. Also, check safety limit for proper operation.
E 19
MCBA return sensor detected temperatures in
excess of 200°F for an extended period of time
• See possible causes for “b19” error.
E 28
Blower is not running when it should or fan speed
signal not being detected by MCBA
• Loose connection in 120 VAC fan wiring
• Loose or miswired fan speed harness
• Defective fan
E 29
Blower fan speed has not returned to zero rpm
• Miswired fan speed harness
• Defective fan
E 31
Shorted supply temperature sensor
• Shorted or miswired supply sensor wiring
• Defective supply sensor
E 32
Shorted return temperature sensor
• Shorted or miswired return sensor wiring
• Defective return sensor
E 35
Flue gas temperature sensor short circuit
• Shorted or miswired flue temp sensor wiring
• Defective flue temp sensor
E 36
Supply water temperature sensor circuit open
• Loose or miswired supply sensor wiring
• Defective supply sensor
E 37
Return water temperature sensor circuit open
• Loose or miswired return sensor wiring
• Defective return sensor
E 40
Flue gas temperature sensor circuit open
• Loose or miswired flue temp sensor wiring
• Defective flue temp sensor
E 44
Internal control failure
• Reset the control. If problem reoccurs, replace the MCBA.
E 52
Flue gas temperature over 230°F
• Heat exchanger needs to be cleaned
• Boiler over-fired
• Air-fuel mixture out of adjustment - consult factory
E 60
Internal control failure
• Reset the control. If problem reoccurs, replace the MCBA.
C. Trouble shooting problems where a hard lockout code is displayed. When a hard lockout occurs, the boiler
will shut down and the display will flash the letter “E” followed by a two digit service code. Once the condition
that caused the lockout is corrected, the boiler will need to be manually reset using the RESET button on the
display.
