Multi-Channel Water Level Expansion reads 0

My Multi-Channel Water Level Expansion reads 0.
It has been working fine since I got it.
Today all channels are reading zero.
If I try to celebrate it just says zero
I have unplugged it plugged it to other ports on the usb hub.
I have rebooted the reef angle several times and have reprogramed it with the wizard.
Any ideas or do you think it just went bad?

Check for any signs of water damage.

No obvious signs water damage.
I did not think there would be because its in a sealed part of the stand away from any water for electronics only.
Do you think humidity could travel up the air lines and cause condensation inside ?
