"FILL" in temperature display on Pro

Does anyone know what it means when the message FILL flashes along with the target temperature on the Pro?

There is a dedicated section for the Pro in support docs: Anova Pro Support, but it doesn’t seem to contain any different information to the others.

‘Fill’ would seem like a low water indicator to me, but that is only a guess as I don’t have a Pro.

It says Lo and won’t heat/pump when low on water. Everything works when it says FILL - that’s what perplexes me…

You may need to email support and ask them.

I did some more testing. Turns out it is related to low water after all. I usually go up to about 1/2 inch above min line. I need to go 1 in above the min line to get FILL to disappear. So it is like an early warning indicator.

Thanks for the suggestion.

Glad you solved it.

Note that no section of the meager user manual covers this issue. The unit requires filling water above the minimum line but still displays a warning when the water line is not one inch above the minimum line. How about shipping the unit with an actual user manual ?
