Google keywords are failing me. I woke this morning to my Hydor ATO beeping. Before I got into the room I was imagining a flood or broken return pump or something terrible.
I was happy to find everything working as expected except for the ATO.
It's beeping with all the lights on solid. I've tried unplugging/plugging, on/off. The ATO pump works when I plug it directly into the wall.
When I turn it on, it flashes for a bit, then immediately goes into beeping. Water does appear to be touching the min level prong.
Anyone seen this before? Any suggestions?
