How does the appliance react when error code occurred
E1 Water filling exceed pre-set time
If the inlet valve has been opened for 4 minutes but the water quantity hasn't reached the
desired value(measure by pluses), E1 would occur.
When E1 occurs, the drain pump will run until flowmeter keep motionless for 2 minutes
and all the other components will be stopped immediately. At the same time, the buzzer
will alarm for 30 seconds and error 1 will be shown.
E3 Heating exceed pre-set time
If the heating element has been working for 60 minutes but the water temperature
detected by NTC hasn't reached desired value. E3 would occur.
When E3 occurs, the drain pump will run until flowmeter keep motionless for 2 minutes.
and all the other components will be stopped immediately. At the same time, the buzzer
will alarm for 30 seconds and the error 3 will be shown.
E4 Overflow
At any time, if overflow micro-switch act and keep for longer than 2 seconds, the E4 would
occur. When E4 occurs, the drain pump will run until flowmeter keep motionless for 2
minutes . and all the other components will be stopped immediately.
At the same time, the buzzer will alarm for 30 seconds and error 4 will be shown.
Note: Priority level of E4 is the highest. E4 operation is valid after other error operations
have done. When E4 operation has done, all the others are invalid.
E6 Open-circuit failure of thermistor
In test program, once open-circuit failure of thermistor is detected by controller, the E6
would occur. When E6 occurs, the drain pump will run until flowmeter keep motionless for 2
minutes. and all the other components will be stopped immediately.
At the same time, the buzzer will alarm for 30 seconds and error 6 will be shown.
