7.3 High current lock
In the final spinning, when detecting high current, perform a defoaming treatment firstly. If still detecting several consecutive
over-current, it will enter the Spinning Load Abnormality Fault alarm mode, displaying "E901". Meanwhile, the buzzer beeps
6 times in 0.05 second ON-0.05 OFF. Except for the Start / Pause button and the Power switch button, all the buttons are
locked. Save the operating parameters before fault. Press the Start button to clear and continue the previous state.

button and the Power switch button, all the buttons are locked. Save the operating parameters before fault. Press the Start
button to clear and continue the previous state.
7.5 Water level sensor abnormality
When the detected water level frequency is greater than 81.92 kHz or less than 16.384 kHz, it indicates the water level sensor
is open-circuited. It will enter the Water Level Sensor Abnormality Fault alarm mode. Meanwhile the buzzer beeps 6 times
with 0.05 s OFF-0.05 s OFF.
7.6 Water heating pipe abnormality
When the heating tube is turned on, or the heating tube temperature rise is not more than 2 ℃ after operating for 4 minutes,
or the tube operating signal can not be detected for 4 consecutive seconds, it indicates the water heating tube relay is
faulty or the water heating tube harness is faulty. It will enter Water Heating Tube Working Abnormal Failure alarm mode.
