Alarm Code Alarm Cause Solution
Sterilization failed! (1)adjust the tightness of door seal may behave leakage.(2)Replace the door seal.
E 04
E 05
Pressure can not
be exhausted!
(1)check the opened-solenoid valve(Ev1) and drain-solenoid valve(Ev5),take out and clean
the s openedpool.(2)check three-way piece to used-water tank,open and clean it.(3)check the
-Solenoid valve(Ev1) and drain-solenoid valve(Ev5) power is DC 24V.
E 06
Door is opened in
the working!
(1)check the door hook and door signal switch is good? To maintain contact contact point
between them.(2)open the door,check leading point of electronic lock is retracted?
Replace the electronic lock.
E 07
Operation over
time!
(1)adjust the tightness of door seal may behave leakage.(2)Replace the door seal.
(3)check the opened-solenoid valve(Ev1) and drain-solenoid valve(Ev5)and vacuum-solenoid
valve(Ev4),take out and clean spool.(Judgment of leakage Method: mist of water
Drop on silicone tube and hot).
(4)check the heating bar,Judgment Methods: the Ω ≈measurement resultof resistance( ) 68
~73 (750W);50~55 (1000W).if measurement result of resistance( ) ,it is broken!Ω Ω Ω ≈∞Ω
(5) measurement result of resistance( ) 30check the heating coil,Judgment Method: Ω ≈
~37 (1500W).if measurement result of resistance( ) ,it is broken!and check Ω Ω ≈ ∞ Ω
electronic emperature Relay of heating coil,t poor contact point between the connectors
and jacks.
(6)check the steam gener ator is blocked?J udgment Methods: the silicone between
the water pump and water pump-solenoid valve is be bloated.
(7)check water pump is be broken?Judgment Methods: Very loud sound and water in silicone
have move forward?
E 09 Over temperature!
Measure:temperature sensor resistance value( ) 1000+(Ambient temperature *3.8)Ω ≈ ℃
(1)if measurement result is OK,check poor contact point between the sensor and the
control board.(2)if measurement result is No,replacing the temperature sensor.
E 08 Over pressure!
check the opened-solenoid valve(Ev1) is be blocked? open the opened-solenoid valve
(Ev1),take out and clean spool.
