The two indicator lights of the water purifier ppf and uf are not lit, what is the fault?

This is most likely due to the fact that one of the resistors has burned out, and in this case the resistors must be replaced, so that there are no problems at all.

In this case, it is very likely that there is a virtual connection in his circuit, or some resistors in the circuit are damaged, so this situation will occur.

What is the reason why the two indicators of the water machine are not lit? If the indicator light is not on, it may be just that this piece is in poor contact.

Both PP and PPF are high-density fiber cotton filters that are typically used on the first stage of filtration on water or water purifiers. PPF is denser than PP and can be used for pretreatment of tap water; PP cotton filter element, also known as meltblown PP filter element, is a tubular filter element made of non-toxic and odorless polypropylene particles, which is heated and melted, spinnereted, traction, and accepted and formed; If the raw material is mainly polypropylene, it can be called PP solution spray filter element. The PP can be replaced with the PPF, depending on whether it is suitable for its own situation.

If the water production slows down after replacement, you should see if there is any blockage, see if there is a mistake in the operation, whether there is a problem with the quality of the product, if there is no problem, you can ask a professional to take a look.

I don't know the washing machine, why don't the lights of the two indicators light up? What is the fault, you can consult it, what is the fault will give him after-sales service.

Faults**:1When the fault code displayed on the panel is E1, it is an overtemperature fault, causing the device to be locked and the power supply needs to be restarted.

2.When the fault** displayed on the panel is E2, it means that the temperature sensor is faulty.

3.When the fault** displayed on the panel is E3, if the water level does not reach 60 seconds after start-up, the cold water probe fails.

4.When the fault** displayed on the panel is E4, it means that the cold water probe is installed in reverse or shorted.

5.When the fault** displayed on the panel is E5, the hot water probe will not trigger an alarm for 60 minutes.

6.If the machine is dormant or there is too little hot water, it may be caused by a bad main control board or a blocked water outlet and poor steam discharge. 1. The water pump cannot be purified if it is not started.

1) Check whether the high-voltage switch is out of order and cannot jump back.

2) Check whether the raw water pressure is faulty, resulting in a power failure of the low-voltage switch.

3) Check whether the fuse of the transformer is blown out. If so, see if the sintered activated carbon or granular activated carbon filter element is clogged and the pump is overloaded.

2.The pump is working normally, but it does not make pure water.

1) The water inlet solenoid valve cannot enter the water and should be replaced in time.

2) RO reverse osmosis membrane blockage or pump loss of pressure. If the RO reverse osmosis membrane is blocked, it should be replaced in time. If the pump is out of pressure, it should be ascertained whether the pump's structure has deteriorated due to long-term heavy loads or if the filter element is often clogged and is not properly maintained.

3) Whether the first three filter elements are clogged.

3.Leaking pump head.

1) The internal scale blockage of the pump head or the aging of the adhesive will also cause water leakage, which should be repaired in time. In the future, the PP meltblown filter element should be checked frequently to avoid clogging.

2) Check whether the PP meltblown or granular activated carbon filter element is blocked, resulting in the pump head water cannot be sent, and the pressure rises, resulting in water leakage. If so, the granular activated carbon filter will need to be replaced and the pump will need to be repaired.

4.The machine was turned off, but the wastewater was still flowing.

1) If the raw water pressure is greater than the pressure set by the high-pressure switch, only need to adjust the raw water pressure.

2) Check whether the inlet solenoid valve can not work, and replace it in time if it cannot work.

5. The water stop cannot be stopped immediately after it starts, the frequency is very fast and cannot be completely stopped

1) The check valve can not be locked for pressure relief and should be replaced in time.

2) If the high-voltage switch fails, it can be repaired, and it can be replaced.

3) System pressure relief status: check whether each component is depressurized and leaking, and if so, reconnect or replace the parts.

Summary. The fault light of Gree 5081 water purifier may be due to the following situations: 1. The power cord has poor contact or open circuit: check the safety of the power cord connection, and if it is broken, it should be repaired in time; 2. The water purifier is blocked

Check whether the filter element is blocked, and if so, clean the filter element in time; 3. Water leakage: check whether there is water leakage in the water pipe, and repair it in time if there is; 4. Poor drainage of the water purifier: check whether the drainage pipe is blocked, and if so, clean it up in time; 5. Lack of water:

Check whether there is a shortage of water in the water pipe, and if so, adjust or replenish the water in time; 6. The temperature is too high: check whether the temperature of the water purifier shell is too high, if it exceeds the normal value, it should be checked and repaired in time.

My water purifier is often clogged, it can't make water automatically, the screen light is all on, and the filter cartridge is all replaced with new ones, what is the reason?

1. The liquid filter element itself is not clean, and the new filter element may not be installed correctly, or the filter element is blocked, resulting in poor water flow; 2. Sediment accumulates in the clean water tank, or there are bubbles in the clean water tank, which affects the water flow; 3. The contact of the power cord is only delayed, resulting in insufficient power supply and affecting the work of the water purifier; 4. There may be dirt or impurities inside the body, which will affect the normal operation of the water purifier.

But manual will fill a bucket of water.

It should be a poor contact with the power supply.

After the bucket of water is used, there is no automatic water production function, and the whole machine is flashing and shining.

Check valve relief, high-pressure switch, or level switch malfunctioning.

Thank you. Will the sewage valve work immediately for forced flushing?

Forced flushing means that the shirt is flushed with a higher water pressure, and the sewer valve still needs to work properly to prevent the backflow of sewage and pollution of the environment. Therefore, during the forced flushing process, the sewage valve should work immediately to ensure that the sewage does not flow backwards.

But the sewage valve of my machine is not working immediately, is the sewage valve blocked?

The sump valve does not work immediately and can be caused by a number of reasons, and the blockage is one of them. You can check whether the Suibeiwu sewage valve is blocked, for example, to see if the valve is stuck by foreign objects or whether there is any buildup in the pipe, etc. In addition, it is also possible that the device has its guess or other problems, such as circuit faults, sensor faults, etc., which need to be further investigated.

Dear, hello, I am glad to answer for you what is the situation when the fault light of the Gree 5081 water purifier is onAnswer: When using the water purifier daily, if the fault light of the water purifier is always on, it indicates that there is a fault, which needs to be investigated and repaired according to the correct method. The master is resistant to deficiency, and the master suggests that you can check and maintain according to the following fault possibilities! Faults**:1

If it is not started, the cause of the failure may be power failure, switch failure, short circuit of water pump, short circuit of transformer, failure of water level controller, and failure of computer box. It is necessary to investigate one by one and take measures according to the cause of the failure, such as power outage, and wait for the power supply to be restored before use; The low-voltage switch fails, disconnect the power supply, and repair the switch. Fault 2:

After the water is full, the cause of repeated jumping failures of the machine may be insufficient raw water pressure, check valve pressure relief, failure of high-pressure switch or liquid level switch, water leakage of various components, etc. It is necessary to find professional personnel to come and repair it, because the situation is more complicated. Fault 3:

The pressure barrel is full of water, and the pure water cannot flow out, and the failure may be due to the air pressure of the pressure barrel being discharged, the post-activated carbon being blocked, and the ball valve of the pressure barrel being damaged. Repairs require replacement of pressure barrels, ball valves, activated carbon, etc. Fault 4:

The reasons for the failure of insufficient pure water flow may be the blockage of the first three filter elements, the insufficient pressure of the high-pressure pump, the blockage of the RO membrane, the insufficient pressure of the pressure barrel of the imbalance of the wastewater ratio, and the low pressure of the raw water and dust, etc., which need to replace the filter element and increase the pressurized pump according to the situation. Fault 5: The cause of water leakage near the pipe interface may be that the pipe head of the PE pipe is not flattened, the pipe plug is not plugged in place, and the nut is not tightened, which needs to be dealt with one by one and then tested.

The water is not purified for two or three minutes after the power is turned on, and the purification is stopped for two or three minutes after the power is off.

How much water pressure do you have, dear?

The water pressure was tap water and there was no problem before.

It may be that the water pressure is low pro.

The water pressure has not changed, how to increase the water pressure.

What kind of water purifier are you, dear?
