2, check the low-voltage switch is malfunctioning, can not connect the power
3, check the pump and transformer is short circuit, or the whole line connection is wrong
4, check the high-pressure switch or water level controller fails, can not be reset
5, check the computer box is faulty (referring to microcomputer type)
Second, high-pressure pump work, but can not make water
1, high-pressure pump loss of pressure
2, there is a fault in the inlet solenoid valve can not feed water (pure water waste no) (whether reverse)
3, Pre-filter plugging (pure water or waste water are small)
4, check valve failure (no waste water)
5, automatic washing solenoid valve failure, can not effectively shut down (has been in the flushing state)
6, the computer box fault can not turn off the recoil solenoid valve (has been in the flushing state)
7, RO membrane blocked
Third, high-pressure pump non-stop

2, check valve is blocked, no pure water
3, high pressure failure, can not take off
4, solenoid valve failure, can not effectively open
Fourth, high-pressure pump downtime, but the water kept
1, solenoid valve failure, can not effectively shut off
2, the computer box is faulty, can not turn off the solenoid valve (referring to microcomputer type)
3, the inlet solenoid valve is not strict, or installed anti-check valve back to the water caused by the non-stop wastewater, the two cases can flow away the wastewater is not the same, the former is tap water, the latter is pure water quality is not the same, the amount of water Not the same before a more punch, the latter a smaller flow, due to non-stop valve caused by non-stop waste water, you can turn off the bucket valve, water flow stopped, you can judge.
4, the solenoid valve failure, can not effectively water (check method: close the pressure tank ball valve, if there is still wastewater, you can determine the solenoid valve failure).
5, there is a case, turn off the water solenoid valve and then open, if the machine is normal, then determine the water pressure is too high, resulting in the solenoid valve can not be flexibly closed, then consider adjusting the total water into the water to reduce pressure.
6, check valve pressure relief, waste water is small, check the method: turn off the water solenoid valve, if there is still wastewater, you can determine the check valve relief.

2, check the pump pressure is in place
3, check the waste water valve or waste water ratio is too conductive
4, check the water temperature is too low
Ten, made of pure water and tap water TDS value the same
May appear in the product just installed, a wide range of demolition of the water machine, the new installation may be wrong after the high pressure pump and RO membrane shell directly connected to the water after the post-activated carbon at the tee, the high-pressure pump out of tap water directly Into the water tank. Treatment: correct exchange.
Eleven, the machine does not work is why?
1, check whether the blackout, the plug is inserted firmly
2, check the low-voltage switch wiring plug is missing or failure to lead to power contacts can not be returned
3, check the connection terminals of the cable is off
4, check tap water pressure is too low to cause low-voltage switch does not work
Approach:
a, connected to the plug off
b, replace the low-voltage switch
c, put off the cable
Twelve, made of pure water taste bad or smell
1, check the RO membrane filtration effect, whether to reduce or failure
2, check the RO membrane shell of pure water and waste water side is cut off or cracks
3, check the end of the rubber membrane rubber ring size is appropriate or damaged
4, check the role of post-activated carbon is effective
Thirteen, a serious imbalance between pure water and wastewater
1, check the flush solenoid valve is damaged
2, check the proportion of waste water is blocked or too conductive
3, check whether the RO membrane clogging or removal rate of serious decline
Fourteen, the machine kept washing
The waste water is not tight at the beginning or at the beginning of flushing
Fifteen, noisy
1, check whether the original water pipe water, causing booster pump idling, resulting in pure water machine noise
2, the prosecution of raw water is normal, if there is no tower water supply, whether there is gas in the water
3, check whether booster pump failure, vibration is too large, there is friction sound
