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.
