ATK stopped running the pump overnight for some reason

[bureau13]

Anyone ever see this? I woke up this morning to that sound of gurgling return pump cavitation as the sump runs dry, pause while it fills back up from the overflow, and then repeat. No errors in Fusion, ATK claims it's still running. I flip it to On (from Auto) and it thinks it's on, but no water. I then unplugged power and all USB (or whatever they're calling it) connectors, plugged them all back in and then it starts working fine. I've had the ATK for a while now, I think maybe I saw this once before and convinced myself I did something wrong. Apparently not. It's one thing if it happens overnight, but if it happens while on vacation, that would obviously be not good.

The Apex ATO was difficult for me. Same issue. Try cleaning the water level sensor. Or just buy a Tunze

I went through two or three Tunze top-offs and they all stopped working more quickly than I thought they should. I guess they all have their issues.
