Technical Data:

The water purifier starts frequently (starts and stops repeatedly)

Failure analysis: high-pressure switch or check valve failure.
Judgment method: power off, close the water inlet valve of the water purifier to see if there is any waste water flowing out, there is no waste water high-pressure switch failure, there is a waste water check valve failure, it is generally recommended to replace them at the same time, the life of the two products is about the same, the single replacement may be short There will also be a failure within a time.

Water purifier does not work

Fault analysis: transformer, low voltage switch, pump, high voltage switch.
Transformer failure: Check whether the power is on, and the power failure is on the transformer.
Low-voltage switch failure: Short-circuit the two lines of the low-pressure switch, the water purifier resumes work, and determine the low-voltage switch failure. After short-circuiting, the water purifier cannot work and the low-pressure switch is discharged. (Prioritize that the water pressure is normal). .
High-voltage switch failure: Short-circuit the two high-voltage lines, and the water purifier resumes work. Determine the high-pressure switch failure. After the short-circuit, the water purifier cannot work and the high-pressure switch is discharged.
Pump failure: Determine whether the waste water can flow out if it can be energized. If there is waste water out but the pump does not respond, determine the pump failure.

Non-stop waste water flow from water purifier

Failure analysis: Water inlet solenoid valve, check valve, high pressure switch, pump, waste water solenoid valve, ro membrane failure.
Judgment method: Give priority to determine whether the water purifier is shut down.
1. Shutdown: Water inlet solenoid valve or check valve failure.
2. Non-stop: Pump, ro membrane, high pressure switch, check valve, waste water solenoid valve failure.
When power is on, close the ball valve of the pressure tank and open the tap of the water purifier to see if the water can flow into a line?
A. Water can flow into a line, one check valve, water inlet solenoid valve, high pressure switch failure.
Detection method-power off to see if the waste water still flows, 1. No flow: Basically it is determined that the high-voltage switch is faulty. 2. Flowing water: the water inlet solenoid valve or the check valve is faulty. It is recommended to buy with the high-pressure switch. It cannot be ruled out whether the high-pressure switch is completely good.
B. The problem that the water flow is not in line, such as ro membrane, pump, and waste water solenoid valve.
Detection method-unplug the water inlet pipe of the ro membrane, see the water pressure, the water pressure is small, the pump is broken; the hydraulic pump is no problem, the ro membrane or the waste water solenoid valve is broken (the waste water solenoid valve troubleshooting is to judge whether the waste water is It has been in the state of flushing, judgment method: power off and then on again, the waste water will be washed first, and then weaken, to see if there is such a state, there is no waste water solenoid valve failure).
