Generally speaking, you would find the panel red light is on and the water outlet with no water and litter water flow when the alarm sounds. We can adjust that is water flow alarm.
1. Please turn off the power of chiller, using a hose connect the water inlet to the outlet and then opening chiller to make sure if the chiller continues alarm.
2. If the alarm is eliminated, it maybe the inlet/outlet water hose of chiller get bended or blocked. If not, we can adjust the internal problem of chiller such as water circulating pipe or pump getting blocked.
Any problem, feel free to contact S&A after-sales department by email:firstname.lastname@example.org.
