E5 temperature sensor failure
The temperature of the heat exchange surface of the water heater is very high and scale will be generated when the water flows. Over time, a large amount of scale will adhere to the surface. interior surface of the heat exchanger, which builds up over time, causing the hot water line to block, which will lead to problems such as a smaller amount of hot water (water pressure apparently low), longer hot water outlet time, etc. at the same time, a temperature sensor is installed at the hot water outlet, which is the water path of the water heater. Scale is likely to build up in the narrowest part of the room, causing a lag in temperature sensing, making the water hot and. cold. In severe cases, the hot water will overheat, causing the overheat protection to block.
It is recommended to first clean and descale thewater heater. Buy a set of instantaneous water heaters without removing the descaler online. Use it to inject a descaling agent into the water heater and clean the inside of the water heater. The operation is simple and convenient. Clean it regularly after using it. This can prevent this problem from happening again. Many people have used it, and it is really effective.
What is the reason for e5 in gas. water heater
Solution:
1. First, check whether the water temperature sensor is damaged. If the water temperature sensor is damaged, replace it with a new water temperature sensor. .
2. Then observe if the combustion is abnormal and if the flame is too big.
3. Finally, check whether the water flow sensor is abnormal.
Cause of fault: The Macro water heater displays E5 because the system detects that the outlet water temperature is too high. When using itization, the outlet water temperature exceeds 93°C for 10 consecutive seconds. the system is interrupted, the water heater stops working, then turns off automatically. The LCD screen begins to display E5.
Detailed information
Other defects:
1. The E0 fault is a high pressure fault. Generally, the operating pressure of. the machine is too high. The system protects the machine. At this point we can check if the ambient temperature and water temperature are too high. We can reduce the water setting temperature by 5°C to solve the problem. The water tank temperature sensor may also be loose. causing a false high pressure report. Finally, air or air entered the system. If it is clogged, the master must re-vacuum and clean the system!
2. Fault E2 is a fault in the temperature sensor in the water tank. We dLet's adjust the probe to see if there is poor contact or replace the water tank temperature probe.
3. E3 failure is usually caused by a reduction or escape from host indifference. The master must recover the leak and fill the indifference to remedy it!
Precautions for safe daily use, maintenance and cleaning
1. Antifreeze (see winter safety tips
2. Please adjust the bath temperature reasonably). in summer to prevent excessive water temperature from harming the body;
3. In order for you to use the gas water heater safely, we recommend that you inspect the airtightness of the gas pipeline every 6 months;
4. When there is a air or water leak in the gas water heater at home, the flame does not go out after the water is turned off, or the combustion conditions are poor, please stop using it. and hascall it immediately.Please do not disassemble or repair the gas water heater yourself when you call our service department;
5. Ask relevant professionals to carry out maintenance and repair of the gas water heater regularly to ensure the normal operation of the gas water heater. gas water heater;
6. Check your home's water lines regularly to prevent loose water connections from leaking and causing damage to your property.

Manual Solution to E5 Water Heater Failure
The reason for E5 is generally high temperature or overheating protection.
The maximum heating capacity of the instantaneous water heater is determined. If the water flow is large, the water temperature will be low. If the water flow is low, the water temperature will be high. .
You can tryto increase the water flow. If it has been adjusted to the maximum, it is likely a calculus blockage problem. The accompanying phenomenon is that the hot water outlet is obviously much smaller than the cold water outlet. If the water flow is low and the fire head remains unchanged, the water temperature will be high. If the water temperature is too high, the water heater will activate the high temperature protection, making it difficult to turn on and heat up in time. After a while, the internal water temperature drops and the water heater may begin to heat up.
Cold water is normal but hot water is small. You should ask yourself why the hot water was big but now it is small. The reason is that more scale deposits were blocking the pipes.

A water heater refers to a device that uses various physical principles to increase thecold water temperature and turn it into hot water within a certain period of time. According to different principles, they can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic energy water heaters, air water heaters, heated water heaters, etc.
The air conditioning part and the hot water part. In fact, these two parts are closely linked, inseparable and must work at the same time. In other words, it can produce hot water and cool the kitchen at the same time. In other words, it also produces hot water while cooling the kitchen.
Principle:
After the compressor compresses the return low pressure refrigerant, it turns into high temperature and high pressure gas and flows through the pipeline. - Gaseous refrigerant under pressure flows through the copper pipe wrapped around the outside of the water tank, heat is transferred to the water tankau through the copper tube for heat exchange. The cooled gaseous refrigerant becomes liquid under the continuous action of pressure and enters. the evaporator after passing through the expansion valve. Because the evaporator pressure drops suddenly, the liquid refrigerant quickly evaporates into a gaseous state and absorbs large amounts of heat.
At the same time, under the action of the fan, a large amount of air circulates through the outer surface of the evaporator. The energy in the air is absorbed by the evaporator and the air temperature drops quickly. , turning into cold air and being released into the kitchen. Then the refrigerant, which has absorbed a certain amount of energy, returns to the compressor and enters the next cycle.
Manual solution to E5 water heater failure:
When the water pressure is too low, insufficient water flow will occur, resulting in whenIf the sensor exceeds 85 degrees, a high temperature alarm occurs. At this time, we must first check whether the hot water outlet valves are all open. Otherwise, just open them. If the water pressure is still low after opening all the valves, then just install a booster pump on the tap water line and start it when using it.
If the faucet is blocked by foreign objects, the water heater is used for too long, and scale deposits block the faucet, this will also cause poor water flow, which will increase the water temperature and will cause an overheat alarm. If this is the case, remove the faucet to clean the scale and impurities, then rinse it and let the water run gently.
The hot water pipe is blocked and there is scale in the pipe, which can also cause overheating. The processing method is the same as here-above. In severe cases, simply replace the water pipe. solve the problem. A very small number of gas water heaters will also trigger an E5 alarm when the gas pressure is too high. In this case, we adjust the air inlet pressure reducer to reduce the air supply pressure, and the water heater can be used normally. strong>.

A water heater refers to a device that uses various physical principles to increase the temperature of water cold in hot water inside. a certain period of time. According to different principles, they can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic energy water heaters, air water heaters, heated water heaters, etc.
The air conditioning part and the hot water part are in reality closely linked and inseparable, and must work at the same time. In other words, all professionaldrawing hot water, it cools the kitchen, or in other words, it produces hot water while cooling the kitchen.
