Failed Ignition Error Boiler has failed to establish flame detec- tion during the igni- tion sequence.
•
Flame is established during the ignition sequence, but not maintained. May be due to low flame signal detection by Control module. •
Inspect flame pattern on the burner head during high and low fire inputs (See page 49). Inspect and clean the burner head. Replace the burner head if damaged.
•
Check the input rate of the boiler at the gas meter during high fire input. If the gas meter measured rate is not at or below 15% of the boiler rating, replace the gas valve.
•
Note: Length of venting and combustion air piping will affect the measure boiler rating.
•
Check the ground lead for a secure connection from Control module ground to the burn-
er mounting plate. Use a ground continuity check to verify a good ground.
•
Remove the ignition electrode. Inspect for damage. Clean white oxides off the electrode.
Replace the electrode if damaged or will not clean.
E 03
Gas Valve Harness
•
Ensure gas valve rectifier cable is properly connected to the gas valve and secured.
•
Reset the boiler control module and retry ignition sequence and boiler operation. If problem continues, replace the rectifier cable.
E 04
Loss of Power Power to the boiler is lost after a lockout has occurred.
The boiler must be manually reset and the original lockout code will be lost. •
Will also occur if the service technician tries to reset a hard lockout by turning the boiler OFF and then ON as an attempt to reset the boiler.
•
Verify polarity and proper ground on incoming 120V power connections
•
May occur in rare cases if there is power interruption, surge or “Dirty” voltage. A relay kit is available and may be installed on the incoming voltage to the boiler.
E 05
Internal Failure Short in either the ignition cable or dis- play panel.
•
Check flat ribbon cable to display for short.
•
Check for moisture at display and repair cause of moisture, dry and/or replace display.
•
Inspect ignition cable replace if necessary.
•
Reset the boiler control module and retry ignition sequence and boiler operation.
•
If problem continues, contact AERCO International Technical Support for additional assis- tance.
E 06
Internal Failure
•
Reset the boiler control module and retry ignition sequence and boiler operation. If problem continues, contact AERCO International Technical Support for additional assistance.
E 07

•
Reset the boiler control module and retry ignition sequence and boiler operation. If problem continues, contact AERCO International Technical Support for additional assistance.
E 08
Internal Failure
•
Reset the boiler control module and retry ignition sequence and boiler operation. If problem continues, contact AERCO International Technical Support for additional assistance.
