Question about Heating & Cooling
This come with the house recently purchased & has no manual. Can you advise what 12 flashing on the control panel means - this occurs in the start up process.
It has plenty of water, filters cleaned & 2 9.5kg gas cylinder with one replace several days ago.
This error is a Flame failure alarm.
It would be good to click HERE and print off all the alarm codes to keep.
As you've just put new gas on, you will probably have to purge the system of air before you get any gas through.
You can probably do this at the heater end.
You first need to check you are getting a spark to the pilot.
If not, check electrical connections, and trace fault to the ignition assembly.
If you are getting a pilot flame (unlikely as you're getting an alarm), you will need to concentrate on the hot-wire sensor and check if it is faulty.
Thanks for using Fixya. Please rate if this works for you.
