3.2 ERROR CODES.
Error codes are produced to assist diagnosis of why the fire cannot/will not start. They appear if the control
detects abnormal conditions with the fire, environment, installation, components, or internal electronics.
Even if a display handset is not connected, checking for the below faults is still valid. The illuminated red LED on
the valve body shows the valve is in error state.
NOTES:
To reset any error, press the power button, marked on the valve.
False errors can be reported if the batteries are faulty or low on power.
This is the only code where the red indicator LED remains permanently lit without flashing. (n.b. the LED may
dim to conserve battery power but remains illuminated).
E00 occurs when fire fails to light after all automatic ignition cycles complete. It is a sign that the
electromagnet within the valve has not received enough power from the thermocouple at the end of the
ignition cycle. The main burner may light for 15-30 seconds, but then extinguish.
Possible reasons:-
• Thermocouple not being heated, or being heated too slowly.
• No gas to pilot or main burner.
• No gas supply, or supply blocked through contamination.
• Pilot pipe blocked between valve and pilot.
• Pilot injector blocked.
• Pilot head damaged or contaminated.
• Fire ceramic misplaced causing carbon deposits to contaminate pilots.
• Pilot air inlet hole blocked by lint.
• No spark at electrode – tracking out somewhere – check for damaged insulation, distance of spark
gap, electrode damage, ceramic damage, dirt or soot on electrode.
• Flame not touching spark electrode (electrode needs to be in the flame so that valve can sense flame
through electrode as well as thermocouple).
• Flame signal shorted out (this can occur if any liquids e.g. leak detection spray has contaminated
pilot terminals connection).
• Spark cable is open circuit (spark may still be present due to ability to jump gaps, but if there is a
break in cable, or terminal connection is not good, valve will not receive sensing current – pilot may
also light but then continue to spark).
• Thermocouple aged or damaged and not producing enough output.
• Thermocouple insulation wire is damaged, electrical current shorting (e.g. to body).
NOTE: If stop is pressed during ignition cycle, E00 may also be generated. This is normal, and not a failure
condition.
THE VALVE CAN ATTEMPT TO SELF FIX ISSUES – When an E00 code has been displayed an internal
recalibration is initiated to attempt to compensate for possible deviations due to contamination, ageing, etc.
If the fire does not light on the first ignition cycle, allow the valve to complete the automatic recycles to
enable the valve to progress to E00 to recalibrate.
Reset error and try again.
