Specific Function:

This circuit board has the function of heating & touch button


  • 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.

Burned Protection:

  • When liquid level below the low-water level, heating function will automatic shutdown.
  • 85℃ Protection Switch: When TEMP higher than 85 ℃,switch off and stop heating.
  • 95℃ Protection Switch: When 85℃ protection switch failed,TEMP higher than 95℃,switch off and stop heating.
  • Sustained heating more than 30minutes,heating function automatic shutdown.
  • When low-water level switch failed,heating function automatic shutdown.

Power :

The computer board energized after 2 seconds to enter the operating state. Buzzer chirping and machine automatically flush for 18s. Icon flashes indicate the respective operating state.

Wash: s=seconds

  • Boot automatically washing for 18s
  • Press the "Strong Wash Button" to automatically washing for 18s.
  • Automatically washing for 18S every 6 hours.
  • Automatically washing for 18S when water lack turns to source
  • Automatically washing for 8S after water full (Cumulatively purify more than 60s, automatically washing for 8S after water full)

Purify: When the switch detected a pressure lower than normal high pressure,the booster pump started to work,inlet valve opened and entered the purify process.

Full: When the pressure reached a certain degree in pressure bucket,high-voltage switch turned off, the machines shut down,inlet valve closed.

Lack: When the low pressure switch detected the water pressure below the set value or the computer board detected low pressure switch off,the machines shut down,booster pump stopped,inlet valve closed, buzzer chirping for 10 seconds

Check: Continuously produced water for 6 hours(no water full), it means something wrong happened to the machine and entered the check process, buzzer chirping for 10 seconds.
