E3 means over low water temperature alarm
When alarm occurs
The error code and the temperature will be alternately displayed
The alarm sound could be suspended by pressing any button
Under low ambient temperature( e.g. in winter)
When the cooling water temperature is lower than factory setting startup temperature
It is easy to cause E3 alarm
Now I show you the simple troubleshooting of E3 alarm
1、Startup machine(e.g. laser) to rise cooling water temperature
E3 alarm will be automatically eliminated
2、If the chiller works in a larger temperature difference
Add warm water into the water tank until the water temp restore to normal value
E3 water temperature alarm can be eliminated
If the chiller continues alarming
It is possible that temperature controller or sensor is faulted
