I am not convinced but that other post says it does that for her twice a year. Ours did not. It has never done it again.
trying to see if anyone knows of this way it can do this, but realistically. It hasn’t done it all the time or twice a year. That is what was so puzzling.
It has indeed done it, you just didn’t see it.
If it doesn’t do it, it is malfunctioning.
