ATO high/low and beeping sound

It seems like this could be indicating water damage but I opened the panel and I do not see anything. It looks pristine to my eyes.

Any suggestions?

Mine does that once in awhile. Generally when it's just a touch too full. It can't discern whether it needs water or not. I wouldn't worry about it. Been running mine for about 2 years now. Never let me down.

The water damage is usually associated with the power input.

Sorry for the dumb question: but anything I should be looking for?

I am letting the unit air dry to see if that does anything currently

Great news! Letting it air out overnight apparently fixed whatever was wrong

Thanks!

What is the code you got? Usually water damage is under the power supply socket and caused by plugging in a power supply tip that landed in water.
