This morning I noticed the Diode Chiller in alarm. I added 150ml to rest the float switch and the another 250ml as per Jeff Bartlett's advice. Because the Famis task (#4140) of checking the chillers and adding necessary water was completed yesterday (without being able to accurately diagnose the water level in the diode chiller)and the alarm went red today, there is a plan to remedy this issue being set into motion.
