To be more clear on that, I didn't cover it the night before, it started to sprinkle around noon.
I went out to cover when I noticed it still smoking, when I flipped the lid open it was wet inside and smoldering, That's when I took the picture, I went to get a bucket and when I got back it was...
No they weren't wet it was dry out. It got cold that night (27*) the hopper lid was closed, I think the moisture came from carbon monoxide condensation.
No damage, I soaked it down with a couple of buckets of water and scooped the pellets out with a fireplace shovel into and ash pail. After it dried for a day, I vacuumed out the rest of the pellets and ashes. Today I put a scoop of pellets in and fired it up.
It seems ok, but I'm a bit worried...
It was about 45* outside, I live in Michigan, I keep the insulated blanket on year around. I've had it for 6 years and hundreds of pounds of pellets and never had this problem before
I shut down my 680 after a higher heat cook without bringing the temp first. It smoked all night and I had a fire in the hopper the next day.
I hosed it down and it seems OK now. I have owned this grill since 2014 and never had this happen before.
Has any one else seen this?
