Part 12 - Troubleshooting

A. Boiler Error and Fault Codes

If any of the sensors detect an abnormal condition, or an internal 

component fails during the operation of the boiler, the display may 

show an error message and error code. This message and code may 

be the result of a temporary condition, in which case the display will 

revert to its normal readout when the condition is corrected, or it may 

be a condition that the controller has evaluated as not safe to restart 

the boiler. In this case, the boiler control will be locked out, the red 

FAULT light will be lit, and the message “LOCKOUT” will be displayed on 

the readout in the lower line.

The boiler will not start until a qualified technician has repaired 

the boiler and pressed the RESET button for more than 1 second. If 

there is an error message displayed on the readout, and the message 

“LOCKOUT” is not displayed and the FAULT light is not lit, then the 

message is the result of a temporary condition and will disappear 

when the problem corrects itself.

IMPORTANT NOTE: 

If you see error messages on your display readout, 

call a technician immediately, since the message may indicate a more 

serious problem will occur soon.

B. Boiler Error

The controller will display an error code and message when an error 

condition occurs. These error codes, descriptions, and recommended 

corrective actions are described in Section D.

C. Boiler Fault

1. The controller will illuminate the red “FAULT” indication light and 

display a fault code and message when a fault condition occurs. The 

alarm output will also activate. Most fault conditions cause the CH 

pump to run in an attempt to cool the boiler.

2. Note the displayed fault code and refer to Section D for an explanation 

of the message along with several suggestions for corrective actions.

3. Press 

RESET

 to clear the fault and resume operation. Be sure to 

observe the operation of the unit for a period of time to assure correct 

operation and no reoccurrence of fault message.

DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN 

SUBMERGED IN WATER.

 Immediately call a qualified service 

technician. The appliance MUST BE replaced if it has been 

submerged. Attempting to operate an appliance that has been 

submerged could create numerous harmful conditions, such as 

a potential gas leakage causing a fire and/or explosion, or the 

release of mold, bacteria, or other harmful particulates into the 

air. Operating a previously submerged appliance could result in 

property damage, severe personal injury, or death.

NOTE: 

Appliance damage due to flood or submersion is considered 

an Act of God, and IS NOT covered under product warranty.

When servicing or replacing components that are in direct contact 

with boiler water, be certain that:

•  There is no pressure in the boiler. (Pull the release on the relief 

valve. Do not depend on the pressure gauge reading.

•  The boiler water is not hot.

•  The electrical power is disconnected.

•  The gas is shut off.

Failure to make these checks could result in substantial property 

damage, serious personal injury, or death.

Label all wires prior to disconnecting them when servicing the 

boiler. Wiring errors can cause improper and dangerous operation. 

Failure to follow these instructions may result in property damage 

or personal injury.

If overheating occurs or the gas supply fails to shut off, do not turn 

off electrical power to the circulating pump. This may aggravate 

the problem and increase the likelihood of boiler damage. Instead, 

shut off the gas supply to the boiler at the gas service valve. Failure 

to do so may result in property damage, personal injury, or death.

NOTE: 

If system return temperatures are maintained below the dew 

point, condensation will form on the inside of the boiler cabinet and 

cause some internal sheet metal components to rust.
