Specific Function:
This circuit board has the function of heating & touch button
1.Touch:
Hot: short press to drain hot water,long press to start and stop the heating function.
Cold: short press to drain cold water,long press to start strong wash function.
2.Burned Protection:
(1) When liquid level below the low-water level, heating function will automatic shutdown.
(2) 85℃ Protection Switch: When TEMP higher than 85 ℃，switch off and stop heating.
(3) 95℃ Protection Switch: When 85℃ protection switch failed,TEMP higher than 95℃,switch off and stop heating.
(4)Sustained heating more than 30minutes,heating function automatic shutdown.
(5)When low-water level switch failed,heating function automatic shutdown.
3.Power:
The computer board energized after 2 seconds to enter the operating state,buzzer chiroing and machine automatically wash for 18S.
4.Wash:
(1)Boot automatically washing for 18S
(2)Press the “Strong Wash Button”to automatically washing for 18S.
(3)Automatically washing for 18S every 6 hours.
(4)Automatically washing for 18S when water lack turns to purify.
5.Purify:
When below the low-water level,the booster pump started to work,inlet valve opened and entered the purify process.
6.Full:
When reach to high water level,the machine shut down.
7.Lack:
When the low pressure switch detected the water pressure below the set value,the machine shut down,buzzer chirping for 10 seconds.
8.Check:
Continuously purify more than 6 hours,the machine entered the check process,buzzer chirping for 10 seconds.
