Got my EX6 yesterday. 1st cook grill steaks and seared great at 500 degrees. No issues. On clean up this morning so some flaking on the heat distributor over the fire pot of some type of smoking.
Today doing baby backs
2nd cook smoking baby ribs had cavity formed twice over the auger and pellets stop flowing into the pot. The second time I noticed the temperature dropping and went and checked the hopper and found the cavity and stirred the pellets, however the glow plug did not fire to reignite the fire as the pellets starting falling back into the pot. I'm using weber pellets I order when I order my grill. Both times I had to pull the ribs off clean out the fire pot and restart the grill. Pulled the ribs off and put in the oven to continue the cook while I got the grill going again.
Update, just found another cavity in the pellet hopper over auger, saved fire this time by stirring pellets and kept cook going. I would recommend checking pellet hopper ever 30 minutes and stir pellets over auger so pellets fall into auger. This makes the third time in this low and slow cook for baby backs.
Continually stir your pellets to make sure a cavity doesn't form. I have written to Weber on both issues.
As a engineer who has programmed control systems for the past 30 years I noticed the following.
Issues:
1) No alarm when over app or on controller when on Smoke Fire when temperature dropped below set point. this should occur at 25 degrees below minimum, this would give the user and chance to react and save the cook from having to shutdown.
2) No alarm to let you know pellets are not following up the auger
3) The glow plug doesn't try to restart the fire when the temperature drop below 50 degrees of set point. This unit holds the set point so tight when it's working, I see no reason why this is not setup to do this. You could fire the glow plug for a period of time trying to restart the fire pot, if the temperature doesn't start to rise then go into shutdown mode. There is no reason that this system should not do this.
4) No audible alarm when the timer is up over the app. No alarm when the temperature falls below the set point by 25 degrees.
Also I still would like to know if the flaking on the heat distributor over the fire pot is suppose to be flaking the coating off as shown in the Photo in my original report. Also attached is a photo of the flakes in the bottom of the grill.
