Stove failed to ignite

Symptoms: Stove failed to start a fire, or displayed a Failure to ignite alert message.

Resolution:  Clearing the Alert:

You can clear the alert code by pressing and holding the On/Off button at the top left for several seconds.

Cause:

What causes failed ignition:

When you press the start button, there are 3 main systems that all work together to get a fire going.

1) The exhaust fan spins up to move air through the combustion circuit

2) The auger will start feeding pellets

3) The igniter will start getting hot.

This video will show what causes a failure to ignite, but it is usually caused by one of the previous systems not engaging properly/promptly:

If the igniter takes too long to get hot, it can let too much fuel fill up the pot.

This video will show how to test the igniter's strength and positioning:

Limited airflow could also cause a delay in ignition

This video shows the importance of airflow, and possible restrictions or leaks in the system:

Here is the best way to physically test your airflow/pressure:

How to test vacuum pressure/airflow within diagnosis menu:

Press and hold the Enter button (left arrow) until the set data menu appears.

Scroll down to #6 Diagnosis and press Enter.

Once in, you can select the simulated combustion level H01-H05 (1-5 bars)

Press the Enter button twice to select Exhaust

Press Up arrow to engage the exhaust fan.

Now that the exhaust fan is engaged, as long as the ash pan and front door are sealed, it should create a vacuum pressure inside the main chamber.

Take a 1/2 sheet of standard printer paper,( torn in half), and hold it to the 2" intake pipe behind the stove (would need to remove your outside intake pipe if installed)  

There should be enough pressure created by the exhaust system to hold the weight of that paper.  If you do not have any/very limited pressure, it could indicate a vacuum leak or blockage in the exhaust system.  While performing this test, you can open up the Tee cap at the base of the piping and then retry the test.  If the pressure returns and holds the paper, it indicates the problem is up inside the piping between the Tee and the top exhaust cap.

Also, keep in mind that the stove always assumes a clean/empty burn pot.  So make sure that there is no leftover fuel or residue from the previous burn.  Starting an ignite cycle with fuel already present in the pot is the most common cause of "backfire" or "bang-to-life" type startups.

Also, keep in mind that if the hopper got below around ¼ full, this could also be the cause of some intermittent feeding interruptions due to low density at the bottom of the hopper/auger junction.

The timed ignition sequence always assumes 1) an empty burn pot and 2) a fully primed auger with a full hopper (for density calculations)

Many times, simply filling up the hopper and restarting will solve your issue.
