Code Description
Error of sensor T5U (upper water temperature sensor)
E0
Error of sensor T5L(lower water temperature sensor)
E1
Storage tank and Wired Controller communication error
E2
Evaporator temperature sensor T3 error
E4
Ambient temperature sensor T4 error
E5
Compressor discharge temperature sensor TP error
E6
Electric leakage error
If PCB current_induction_circuit check the current
E8
difference between L,N >14mA, system consider it as
"electric leakage error"
Compressor suction temperature sensor TH error
E9
E-heater open-circuit error IEH (Current difference E-
EE
heater on and off )<1A
Clock chip error
EF
E-EPROM chip error
Ed
Solution
Maybe the connection between sensor and PCB has released
or sensor has been broken.
Contact a qualified person to service the unit.

Maybe the E-heater has been broken or bad wire connection
after repair.
Contact a qualified person to service the unit.
Maybe the chip has been broken, but unit can work well without
clock-memory, so it is needed to reset clock when power put on
again.
If necessary, contact a qualified person to service the unit.
