Laswim EC Series Salt Chlorinator Showing E3: What Should You Check?
The E3 code means there is no water in the unit. The unit needs enough water to produce chlorine.
No Water in the Unit
Check both the water supply to the unit and the water level detection device, in that order.
Check in Order
Check the pump and valves
Is the circulation pump running? Are the valves in the operating position? Make sure water is actually reaching the unit.
Check for leaks and air in the pipes
The manual says to check for leaks or air in the pipes, as these can leave too little water in the unit. Fix the cause and make sure the system has water normally before use.
Fix the water system first
Fix the pump, valves, leaks or air in the pipes so the system has water normally, then start the unit.
Have a technician check the water level detection device
Including inspection and cleaning per the manual when needed.
E3 Doesnt Automatically Mean the Water Level Detector Is Faulty
You need to tell which case it is to fix the right problem.
Switch off and disconnect power before removing equipment or doing maintenance, and have a technician carry out internal inspection.
