AOSmith Cyclone dry fire alert

i just went to call that had this alert. 
Auto test complete. A five second dry fire auto test complete. Unit didn’t fire up until I cycled power. I work with these quite a bit but I’ve never seen this. Once I reset it, the alerts disappeared so I can’t bring up what happened. Has anyone experienced this? Or can explain what happened?

    I will take a stab at this one:

    I believe this was a test that occurred a little over 12 and a half hours before you arrived to take that picture. The test was a success. The test took about 5 seconds. And the test will only happen during the first heating cycle. Also if you wanted more information about this, you should have scrolled down before you cycled the power off and cleared this alert.

    I think that pretty much sums it up

    Hope you find this helpful

    I think the "Don't Be Such A Smart A**" button is marked LOL below

    Yes. Lol. I did scroll down and it said that this test would not interrupt the heating cycle. 
    Alert code was BD
    it wasnt until I did a hard reset that the heater started up. It’s just a strange to me. 😀
    just thought I’d try to get more info on it.
