Dastaco calcium reactor problem

[authentic]

Works for months then I get an alarm regularly and I have to unplug after awhile starts working flawlessly again
Anyone know what’s causing this? Please let me know

what is the alarm? there are different ones. see the attached

if its not a co2 issue its likely that the float switch is getting stuck. i would clean the reaction chamber. that is the most frequent cause of alarm that I've run into
