Note: In event of multiple errors, the highest error number is displayed first.
Note: Error codes 18 and 65 - Hard Lockout will not expire. Requires operator reset. No volatile memory (error will not be remembered if power is off).
Error codes 6, 23, 62,63 and 64 - Soft Lockout of 1 hour duration if not reset. Control will then resume normal operation. If source error is still
present a second soft lockout it possible.
All other codes - No lockout. Control will resume normal operation immediately when source error is resolved.

Explanation
status is
displayed
Control relies on pressure switch to
verify inducer motor is running and
vent is clear. Switch should open at
end of heat cycle, but this did not
occur
Control requires strong enough signal
to verify flame is present. Signal is
too low.
Control circuit is sensing flame
× rectification when there should be
none.
Control believes it is defective
Pilot is being sensed too soon in
×
ignition sequence
Pilot is being sensed too late in
×
shutdown sequence
Control relies on pressure switch to
verify inducer motor is running and
vent is clear. Switch must close at
start of heat cycle, but this did not
occur
Temperature sensor is not providing
expected reading
Control did not detect voltage
difference between flame sense wire
and ground
AC frequency is incorrect or noisy
Line voltage (or, possibly thermostat)
is either too high or too low
Certain types of thermostat may not
be compatible with control circuitry
Unstable line voltage - possibly too
many heavy loads switching on and
off
Control sensed consecutive instances
of no flame signal while trying to
light pilot.
Control sensed consecutive instances
of loss of pilot flame signal AFTER
main burners are lit.
Control is sensing something wrong
with electrical circuitry
Control sensed water temperature
which is too high for safe boiler
operation.

Things to look for
1. Check pressure switch
2. Check tubes going to pressure switch, verify no obstruction.
3. Check wiring to pressure switch
4. Remove wire connections to pressure switch. If code persists,
replace control."
1. Check pilot flame sense is clean
2. Check for proper ground
3. Check wiring
4. Check for correct pilot orifice
5. Check there are no gas leaks in pilot tubing.
1. Check gas valve
2. Check all electrical connections are tight
1. Try reset by cycling power or push any key.
2. Check wiring to pilot and main valve.
3. Otherwise, control will require replacement
1. Check gas valve
2. Check all electrical connections are tight
1. Check gas valve
2. Check all electrical connections are tight
1. Check pressure switch
2. Check venting, verify no obstructions
3. Check tubes going to pressure switch, verify no obstruction.
4. Check wiring to pressure switch
5. Jumper wire connections to pressure switch. If code persists,
replace control. Be sure to remove jumper.
1. Check sensor is plugged into control board
2. Check sensor wiring is not damaged
3. Scroll display reading to ""bt"", and hold sensor bulb securely in
your hand. It should read temperature close to body temperature.
If not, replace sensor.
1. Check flame sense wire on pilot assembly is not frayed or
otherwise damaged. If so, replace pilot assembly. Note! These
are high temperature wires. Do not attempt field repair.
2. Check there is not moisture collecting on control board
1. Some electric or electronic devices may generate
electromagnetic interference. Verify none is present.
2. Check thermostat connection
Source problem is likely in electrical external to boiler. Control
will clear itself and resume normal operation once the situation is
resolved. Check BOTH line power and thermostat wiring.
Verify boiler works properly by jumping yellow thermostat wires.
If so, replace thermostat (or possible thermostat wires)
1. Check if current draw on this branch circuit from house breaker
box might have very heavy loads switching on or off
2. Check power coming into house Source problem is likely in
electrical external to boiler. Control will clear itself and resume
normal operation once situation is resolved.
1. Check control ground connection
2. Check pilot ignition wire for good condition and connection
3. Clean pilot tip
4. Check pilot tube; assure no gas leaks
5. Check correct pilot orifice is being used
6. Check gas line pressure
1. Check gas valve
2. Check all electrical connections are tight
3 Check pilot rod is clean
4. Check gas line pressure
5. Check for adequate draft
6. Check for adequate combustion air.
1. Check all wiring is correct. Refer to wiring diagram
2. Check there is good ground to pilot bracket.
1. Check water is circulating properly through boiler.
2. Check there is not air in system
3. If pressure relief valve opened, there is definitely a problem
with water circulation!
4 If any of the above 3 are true, the root problem is in hot water
circulation.
5. Scroll display reading to ""bt"", and hold sensor bulb securely in
your hand. It should read temperature close to body temperature.
If not, replace sensor.
