After the instantaneous water heater is connected, it shows what is the cause of the E9 fault E9

Wrap the yellow ground wire on the water heater with copper wire and hit the wall with iron nails). The third type: the first two cases have been done, and the E9 may be the leakage protection switch you installed short-circuited (or you plug it) or remind you that there is a problem with your own wiring and is detected by Shang Shilong, that is, the water heater leakage (Solution:

Replace the 40A CHINT air leakage protection switch or find a professional electrician to check your own wiring). If the first three cases are taken care of, there is also e9. When the screen displays 2 85 or 95, after continuously touching the screen to cool down, heat up, cool down, and heat up, change the screen 11 mathematics to 10 or other numbers e9 to clear it.

There is also the removal of the ground wire on the motherboard by disassembling the machine panel, and the E9** disappears forever. This step is not recommended as a last resort, because although E9 is not a machine failure, it is an additional protection detection for Shang Shilong, that is, the water heater is more than similar products (many similar products will not do E9 ** in order to save costs, save processes, and save trouble), which can effectively assist you to check the fault of your own line or other unknown safety hazards. If you still have questions, you can call their free customer service**:

During normal operation, the water heater will display the basic information of water flow, motor, flame, and temperature on the screen, which is convenient for users to observe and operate. In the fault state, E0, E1, E2 ...... will appear on the display of the water heaterE9 etc. are uncommon**, this is a fault**. Fault** is conducive to after-sales personnel to quickly find the fault part and complete product maintenance.

Different brands and different models of products have different meanings of faults, so querying faults has a certain internality. In most brands, E1 indicates abnormal ignition, E2 indicates abnormal wind pressure or motor speed, and E9 indicates abnormal air pressure.

In the event of an abnormality, the user should apply for after-sales service as soon as possible, so that the after-sales personnel can troubleshoot in time, facilitate the user's life, and ensure the safety of the institution.

Electric water heater. Fault e9 is shown to prevent dry burning protection. The solutions are: 1. The temperature probe is damaged and needs to be replaced. 2. The circuit control board is damaged, and the circuit control board needs to be replaced. 3. Sealant for electric heaters.

If the ring is damaged or leaking, the sealing ring needs to be replaced. 4. Scale accumulation on the temperature sensing probe needs to be cleaned up in time.

The water heater shows that the E9 fault is: 1. The water flow rate is low, if the water output of the faucet is small, it may be because the water flow is not sufficient, resulting in the water heater stepper motor or limit switch cannot operate, so E9** is generated; 2. Low air pressure means that the current air pressure of the water heater is relatively low, so it is necessary to change the air or restart the switch as soon as possible; 3. Excessive scale, if the scale inside the water heater accumulates too much, it will lead to the appearance of E9 failure, then the internal scale needs to be cleaned.

1. Low water flow.

If the water heater shows the status of E9, it may be because the stepper motor of the water heater, or the limit switch has found a certain fault, in this case, you can check the water output of the faucet, if it is observed that the water output of the faucet is not particularly large, then it is likely that the water flow is not particularly sufficient, resulting in the stepper motor or limit switch can not operate, so there will be an E9 fault**.

2. Low air pressure.

The water heater shows E9 may also be because the product has a low pressure failure, in this case, you need to reopen the water heater's on/off key, you can remove this phenomenon, generally E9** indicates that the current air pressure of the water heater is low, if the use of bottled gas, the gas should be replaced as soon as possible.

3. Too much scale.

If it is caused by this situation, it is necessary to clean up the scale inside the water heater in time, and rinse it with clean water.

Hello, the water heater E9 fault is: the water flow is low, if the water output of the faucet is small, it may be because the water flow is insufficient, resulting in the water heater stepper motor or limit switch can not operate, so E9**; Low air pressure means that the current air pressure of the water heater is relatively low, so it is necessary to ventilate or restart the switch as soon as possible; Too much scale, if there is too much scale accumulation inside the water heater, it will lead to the appearance of E9 failure, then you need to clean the internal scale.

Questions. Electric water heater E9 fault solution.

Immediately clean and descale, you can buy a set of fast water heater without removing the scale, use it to inject descaling agent into the water heater to clean the inside of the water heater and the inside of the hot water pipeline, the operation is simple and convenient, use it to clean regularly in the future, when this problem can be avoided again. You can check whether the connection cable is plugged in reliably and whether the temperature probe is damaged. It means that the machine is faulty, and you need to find a dealer to judge you and find a manufacturer to report for repair.

Questions. It's an electric water heater, not a gas water heater.

Knowing the pro.

The failure of the water heater E9 is: 1. The water flow rate is low, if the water output of the faucet is small, it may be because the water flow is not sufficient, resulting in the water heater stepper motor or limit switch can not operate, so E9** is generated; 2. Low air pressure means that the current air pressure of the water heater is relatively low, so it is necessary to change the air or restart the switch as soon as possible; 3. Excessive scale, if the scale inside the water heater accumulates too much, it will lead to the appearance of E9 failure, then the internal scale needs to be cleaned.

1. E9 indicates low air pressure.

The malfunction can be lifted as long as we press the water heater button again. This ** indicates that the current air pressure of the water heater is very low, indicating that we should change the air as soon as possible if we find that it is bottled gas. There is no need to repair it, because it was designed that way when it was developed.

2. It may be the scale of the water heater, and the accompanying phenomenon is the electric water heater.

The hot water is significantly smaller than the cold water. The outlet water temperature probe is open or short-circuited, and the temperature probe is faulty and water ingress. 3. The temperature probe is faulty, the water inlet and outlet temperature probe is broken or short-circuited.

Suggested workaround:

1. The Li Chi indicated by E9 is a low pressure fault, which can be lifted as long as we press the water heater again. This ** indicates that the current air pressure of the water heater is very low, indicating that we should ventilate as soon as possible if we find that it is bottled gas. There is no need to repair it, because it was designed that way when it was developed.

2. If there is scale, it should be cleaned and descaled immediately, and the water heater should be injected with descaling agent to clean the inside of the water heater and the inside of the hot water pipeline.

3. Check whether the connection cable is reliably plugged in and check whether the temperature probe is damaged. If there is a fault, it needs to be replaced or repaired by the manufacturer.

Electric water heater. E9 refers to protection against dry burning. There may be a situation, section.

1. Check whether the temperature probe is damaged and replace the temperature probe. Clause.

2. Check whether the bend excavation control board is damaged, and the circuit control board needs to be replaced. Clause.

3. Check whether the sealing rubber ring of the electric heater is damaged, leaking and burying the core, and the sealing rubber ring needs to be replaced. Clause.

4. Check whether the scale accumulation of the temperature sensing probe is and clean up the scale in time.

Hello, how to solve the water heater E9 fault The answer is as follows: first check whether the connection line is in good condition and whether the temperature probe is damaged. If these problems occur, it proves that the machine is faulty and the water heater cannot be used normally, you can contact a skilled worker for on-site maintenance, or find a seller to diagnose and find a manufacturer to report for repair.

If there is no problem with the water heater, you can buy a set of appliances to quickly remove dirt from the water heater, and use descaling agent to clean the inside of the water heater and the inside of the hot water pipe. If it is a limescale problem, it needs to be cleaned regularly during use to prevent such failures from occurring again. Related knowledge popularization:

1. The E9 fault indicates that the gas pressure is too low at that time, the temperature sensor probe is faulty, and the probe is short-circuited or open-circuited and cannot sense the temperature of the inlet or outlet water. After the water heater self-troubleshoots, it shows that it is stupid to remind the water heater that there is a fault. 2. If it is a gas water heater, it proves that the gas tank is exhausted and needs to be ventilated as soon as possible.

After ventilation, you can restart the water heater with you, and there is no need for on-site maintenance. 3. If E9 appears in the gas water heater, it may be that the water pressure is too low, and the water heater will automatically start the anti-boiling device. In this case, it is only necessary to turn up the water pressure.

4. Water heaters have a regular warranty. Generally, this kind of problem can be reported to the warranty, and daily maintenance and cleaning can also reduce the occurrence of this situation.

Electric water heater. Fault e9 is shown to prevent dry burning protection. The possible reasons are the book auspicious four, first.

1. The temperature probe is damaged and needs to be replaced. Clause.

2. The circuit control board is damaged and the circuit control board needs to be replaced. Clause.

3. The sealing rubber ring of the electric plus nuclear heat generator is damaged and only leaks when changing the posture, and the sealing rubber ring needs to be replaced. Clause.

Fourth, the scale of the temperature probe accumulates, and the scale needs to be cleaned in time.

This answer applies to Wanjiale.

Most brands of electric water heaters such as Midea and Wanhe.

It may be that the temperature probe of the water heater has failed early and cannot work normally. It could be the seal of the water heater.

Aging, deformation and damage. It may be caused by damage to the circuit control board. It may be caused by the aging and loosening of the power cord connected to the temperature sensor of the water heater.

Suggested treatment: 1. The sealing ring of the water heater is made of rubber, if it is not replaced for a long time, it will be aging and deformed, find professional personnel to conduct a full range of testing, replace all the aging rubber rings, so that the water heater can be used normally. 2. The temperature probe of the water heater is around the heating pipe, if there is no long-term cleaning of the rust inside the water heater, it will affect the temperature probe, and there is a large amount of scale on the temperature probe, so it will not be able to work normally, and the water heater should be cleaned regularly, so that there will be no scale around the temperature probe of the water heater.

3. Let the professional teacher do a full range of testing for the heating system of the water heater, especially the power cord connecting the heating pipe, whether it is aging and deformed due to the use of the heating pipe for too long, and replace it in time after finding the problem, especially the circuit control board of the water heater should be detected with professional tools to strengthen the source of the void, and the loose welding point can replace the aging line, so that the water heater will not appear E9 situation.
