Check whether the leakage protector trips, there is generally a recovery button on the leakage protector, and press it to see if it can be recovered to confirm that there is no short circuit.
If you don't know much about the failure of the electric water heater itself, such as the power supply line is burned and broken, the fuse is broken, and the power supply is faulty, it is best to ask a professional maintenance personnel to repair it.
Whether the plug of the electric water heater is plugged in properly.
Extended Materials. An electric water heater refers to a water heater that uses electricity as an energy source for heating. It is one of the three major water heaters alongside gas water heaters and solar water heaters.
Electric water heaters can be divided into three types: water storage type (also known as volumetric type or heat storage type), instant heating type, and rapid heat type (also known as semi-water storage type) according to the heating power.
Although the volume of ordinary quick-heating electric water heater and dual-mode electric water heater is about the same, the internal structure is very different, and the quick-heating electric water heater is only smaller in volume and more powerful than the storage electric water heater, so it is indeed faster than the storage electric water heater in terms of heating speed, but it can not achieve instant heating in spring and autumn, and it needs to be preheated, that is, it needs to wait, and the dual-mode electric water heater can be used in the three seasons of spring, summer and autumn.
Precautions. 1. If the water heater is not used for a long time at home, try to turn off the water heater, otherwise it will not save energy and greatly reduce the life of the water heater.
2. If conditions permit, try to inspect the water heater once a year, mainly to check the heating status, key sensitivity, whether the drain valve is in good condition, and the electrical pipeline and bracket should also be carefully checked.
3. Clean the liner every six months, mainly to clean up the scale on the heating pipe, which is also the main reason for choosing a big brand.
4. If the water heater has been used for three years or more, the heater and thermostat should be replaced once, and professional personnel should replace it.
5. Regularly clean the dirt of the shower and the water trap to prolong the service life of the water heater.
6. Dripping water from the drain valve is a normal phenomenon, and it must not be blocked, otherwise it is very easy to cause dangerous hidden dangers.
7. Do not disassemble the water heater by yourself when there is a quality problem, and be sure to contact the after-sales service for maintenance.
8. Do not spray with water during the cleaning process of the water heater, and do not wipe it with an acidic solution, the appearance of today's water heaters is relatively smooth, so just wipe it gently with a moist rag.
9. The power supply of the water heater should be equipped with a waterproof socket as much as possible.
10. The service life of the electric water heater is generally indicated on the manual, and after the service life of the water heater, try to replace the water heater, and check it regularly if the conditions do not allow.

The water heater power indicator is not on, but it is heated as usual What's going on.
It could be caused by the following reasons:1The electrical outlet has no electricity or poor contact.
2.There is no water in the water heater (or it is not filled), the electric heating pipe is in a dry boiling state, and the reset button of the leakage protection plug jumps up to cut off the power supply. 3.
The water temperature of the water heater is too high, and the reset button of the leakage protection plug jumps to cut off the power supply. 4.If the water heater leaks, the reset button of the leakage protection plug jumps up and cuts off the power supply.

The indicator light is on, but it does not mean that it must be heated, the heating condition is that there must be a water flow, put the water, it will automatically heat, the default temperature of the water heater is changed to contain 38 degrees, of course, you can adjust the height arbitrarily, generally the lowest 30 and the highest 45 degrees. Be sure to put water on to adjust the temperature, and once the water valve is closed, the water heater will immediately turn off the power and stop heating. Suggested Treatment:
1. The indicator light of the electric water heater is on but not heated, it may be that the heating plate inside is damaged, or there is a mechanical failure, which should not have much to do with the line, so in this case, it is best not to repair it indiscriminately, because it may be counterproductive, and there may be danger. 2. The temperature of the heat exchange surface of the water heater is very high, when the water flows through, there will be scale, if it takes a long time, there will be a lot of scale attached to the surface of the heat exchanger, so as to reduce the heat exchange efficiency, and the problem of insufficient heating capacity will occur. Moreover, it will cause the hot water to overheat, causing the overheating protection to go out.

The electric water heater light keeps heating on, what's going on?
The electric water heater light is always on and off for heating, what's going on? The reason why the water heater has been heating is that the thermal switch of the selling wheel is faulty, and there are several possibilities for the thermal switch to be faulty: the switch itself is broken.
Solution: Repair the switch. The solder joints fall off and the line never connects.
Solution: Repair and install the solder joints. The switch is shifted and the heat cannot be transferred in time.

Reason: 1. The electric heating tube is broken, when the electric heating tube is broken, it cannot be heated, you can use a multimeter to test whether there is electricity on the electric heating tube, if there is electricity, it is not heated that the heating tube is broken, and it needs to be replaced.
2. If the relay fails, if the temperature control pre-stage is out of power, it should be that the relay is broken, and the control board needs to be removed and the relay replaced.
The working principle of the household multi-functional water heater is similar to the principle of air conditioning, which applies the inverse Carnot principle, which absorbs a large amount of low-temperature heat energy in the air, compresses it into high-temperature heat energy through compression, and transmits it to the water tank to heat the water.
The whole process is an energy transfer process (from air to water), not an energy conversion process, without heating hot water through electric heating elements, or burning combustible gas to heat hot water.

The power of the electric water heater is relatively large, the electric heating pipe joint is easy to heat and oxidize, and it is often easy to oxidize and break, and the heating relay circuit works, but the heating pipe cannot be energized, and it cannot be heated, so there are many such faults in the electric water heater.

Answer 1, electric water heater safety valve problem: if it is the electric water heater itself, it may be that there is a problem with the safety valve of the electric water heater, when the internal pressure of the electric water heater is heated, when the safety pressure is exceeded, it will drip water from the safety hole to relieve the pressure, and also prevent the cold water from expanding and flowing back to the tap water pipeline after heating. Check the safety valve of some electric water heaters, and if you find that it is a safety valve problem, you can replace it with a new one.
If the electric water heater does not heat, it may be that its temperature controller has been damaged, because the temperature controller will make the water heater heat, if the temperature is too high, when it reaches a certain limit, it will turn off the main switch and be in a state of power failure.
2. In addition, the reason why the electric water heater can be heated is directly related to the electric heating rod. However, after many people buy the electric water heater, it has never been cleaned, which will cause the electric heating rod to be damaged, and there will be dirt on it, which will lead to the inability to heat, and at the same time, the safety factor will be greatly reduced, such as the problem of **.
3. Another reason is that the electric water heater must be installed with a leakage protector, but if there is a problem with the circuit and it trips, it will cause the electric water heater to fail to heat.
My AO Smith water heater has been used for 5 years, has been leaking, and can not be repaired after sale, and then saw on the Internet that Haier's water heater has a very good reputation, so I bought Haier's water heater, the next day Haier's master installed it, only to find that the old water heater could not be removed because of rusty bolts, at that time I and the master were desperate, and finally the master took out an angle grinder from the toolbox, and it took almost three hours to remove the old machine, and then installed the new water heater, during which the master did not complain, Finally, he also said that the dismantling of the old machine is free of charge, and there is no service fee. Kudos to Master and Haier.
How to choose an electric water heater:
1. When choosing an electric water heater, consumers should choose a brand electric water heater. Choosing a brand electric water heater can better solve the "safety" point, the general brand electric water heater will have a built-in patented anti-electric wall technology, real-time safety protection, not only to solve the problem of leakage of the product itself, but also to completely eliminate all the hidden dangers of electric shock caused by the live ground wire, and cut off the hidden danger of electric shock. >>>More
Before cleaning the water heater, cut off the power supply, use the impact force of water to clean the water heater, drain all the water in the water heater before cleaning, and then tear off the hardware such as the shower, leaving only the cold and hot water pipes, and then install one end on the faucet, and the other pipe is used for drainage. Repeat it a few times to clean the water heater. Regularly carry out system sewage discharge to prevent pipeline blockage; And clean the water tank to ensure that the water quality is clean. >>>More
