Code
Message Probable Cause
Warning Fault
– E142 No Burners
Available
All burners have experienced an ignition control module failure, and no burners are
available to produce steam. The unit is unsafe to operate with this fault condition. Fix the
problem before restarting the unit.
Gas supply problem.
– Check the gas supply is open.
– Check for 24 VAC at the gas valve.
– Check the status LED on the ignition control module – three flashes of the red LED
indicate problem with the supply, or gas valve, or a loose connection. Contact your
Condair representative if further assistance is required.
Loose wiring, or defective spark-igniter.
– Visually check the sight port of problematic burner – check for a glowing red spark-
igniter followed by a flame.
– Check the spark-igniter connection. If necessary, replace the spark-igniter.
Faulty ignition control module.
– Check the status LED on the ignition control module – a solid red LED indicates an
ignition control module failure. Replace the ignition control module, if necessary.
– E143 Gas Valve Fail The identified gas valve was energized out of sequence, or when it was not expected
to be energized. The unit is unsafe to operate with this fault condition. Fix the problem
before restarting the unit.
Loose connections.
– Make sure that all onboard electronics are connected according to the wiring diagram.
– Check the status LED on the ignition control module – three flashes of the red LED
indicate problem with the supply, or gas valve, or a loose connection.
– Check connections to all ignition control modules and gas valves. Check for 24 VAC at
location labelled "TH" on the ignition control module.
Faulty gas valve.
– Check for voltage at locations labelled "TH" and "V2" on the ignition control module
after the blower has completed pre-purging the system. If 24 VAC voltage is detected
at "V2" but not at "TH", replace the gas valve. Contact Condair to order a replacement
gas valve.
– E144 Float Level On three consecutive occasions, more than one float level was registering at the same
time. The unit cannot operate without accurate float level reading. Fix the problem before
restarting the unit.
Floats may not be working properly.
– Check the float chamber for scale build-up, and clean if necessary – refer to
"Cleaning
the Float Chamber" on page 53 .
– Check that both floats have equal buoyancy, as described in
"Cleaning the Float Chamber"
on page 53 . Replace the floats, if necessary.
Faulty float board
– Examine the float board for signs of corrosion, splashed water on it, or other damage.
Replace the float board, if necessary.
Obstructions in hoses, or hoses plumbed incorrectly.
– Check for obstructions in the hoses.
– Check that all hoses are plumbed correctly.
