Common faults and troubleshooting guidelines/solutions
Is the working pressure of pure water machine unstable?
If the tap water pressure is lower than 1bar, the instructor will activate the emergency key to restore normal.
The water machine repeatedly starts and stops, and the source water light is on and off?
The front filter element is blocked. Replace the filter element and restore normal operation.
The tap water pressure is unstable, and the water machine starts and stops frequently.
Press the emergency start button to restore the normal operation of the water cooler.
Tap water is full of mud and often rains.
Install automatic pre-filter, automatic backwash sediment, impurities, effectively improve the service life of equipment.
Source water pressure indicator light (water machine does not start)
Check whether the tap water is stopped, whether the pretreatment filter element is blocked, and whether the low pressure valve is damaged.
The source water pressure indicator light and the pump operating indicator light are intermittently on.
Tap water pressure, check the tap water pressure
RO pure water quality is poor
Raw water TDS value ≥300PPM, adding automatic softening system; The RO film is damaged, replace the RO film; Lower operating pressure, adjust operating pressure
Low water yield
The RO membrane is blocked and the RO membrane is replaced. Lower operating pressure, adjust operating pressure.
Ultrapure water quality ≥1us/cm(RO membrane effluent water quality is normal)
Resin failure, replacement of conversion column or purification tank.
The joint is leaking
The pressure is too high, adjust to reduce the pressure; Joint damaged, replace with a new joint.
The water tank is full without stopping
The liquid level system lost the ring and replaced the new liquid level system.
Insufficient water supply to the booster module system
The booster module is damaged, replace the booster module; The constant voltage module is damaged. Replace the constant voltage module.
