Laswim EC Series Showing E1: What Does It Mean?
The E1 code indicates the heat sink temperature is too high. The cooling system, sensor and internal circuitry should all be checked.
Heat Sink Temperature Too High
Check in Order
Tell a technician to check the sensor
Have a technician check the controllers internal temperature sensor and fix the cause.
Have a technician check the circuitry
The manual says to check the hardware circuitry, so a technician should inspect the inside. Dont assume hot weather is the only cause.
How Are E1 and E6 Related?
When E1 appears, the manual says to check E6 as well.
It does not mean low salt, so adding salt will not fix this code.
Switch off and disconnect power before maintenance. Sensor and internal circuit checks should be done by a qualified technician.

Dont assume that. Check the installation area and for E6, and have a technician inspect the hardware circuitry per the manual.
Where should the salt chlorinator be installed?
In a well-ventilated area, with nothing blocking or covering it that would prevent proper cooling.
What if E6 appears together with E1?
Tell a technician to check the controllers internal temperature sensor and fix the cause.
Will adding salt clear E1?
No. E1 is about heat sink temperature, not low salt, so adding salt is not the fix.
