ICP OES 5900 SVDV Water Cooling Issue

Hello, randomly the status light for water cooling will not turn green upon turning on the chiller. Per the instrument troubleshooting I removed the water cooling filter, cleaned and replaced it. I ran a chiller  performance check and all steps passed. I noticed on the dashboard the peltier won't cool below 26.4C. I also see that the camera water flow is 0 L/min. Does anyone have any insights or has experienced this problem before?
