The time is long, no matter what the water heater will be damaged, now Xiaobian collects and organizes the installation method and maintenance skills of the electric water heater and the electric water heater purchase strategy, which is convenient for users of electric water heaters to solve when encountering these problems.

Electric water heater installation method and maintenance skills

First, the installation steps:

1. First, the owner should determine the installation location, then mark it with a pen, then use the impact drill to punch holes and place expansion bolts to fix the water heater. Some owners don't like to smash the walls, or they can use a thin wire to tie the water heater to the fixture.

2. Take out the inlet and outlet pipes, tighten and hold them, then drain the water to fill the container;

3. Accurately connect the power line, neutral line and ground line, and use 16A plug and socket connection mode;

4. Check the water and electricity link to see if there is no water seepage. If there is any leakage, if it is normal, then you can use it for power.

5. Get ready to install the required tools: electric drill, Phillips pen, a square plastic stencil. Firstly, the square plastic stencil is fixed on the wall, and the height is adjusted according to the space of the home. When it is fixed, it is fixed by the screw provided by the original factory, and finally the two holes are fixed by the electric drill. If it is a hot kitchen, its power is generally below 4000W, it can be installed under the kitchen sink or above the water pipes and lines, with splash-proof sockets.

6. This step of the grounding wire is very important, and it is also an anti-electric wall to ensure the safety of the shower. Look at the home there is no ground connection, and some direct ground. On the first floor without a ground line, directly hit a line outside the window and make a depth of 1.5 meters below the ground. In the second floor or above, directly put a hole directly on the wall of the back of the water heater, put a nail into the hole, and then pour some water into it.

Second, electric water heater repair

Electric water heater failure phenomenon 1: leakage protection power supply line trips and can not be reset

Reason analysis: 1 over temperature protector jump 2 circuit component leakage 3 leakage protection plug is broken

Maintenance method:

1 First check whether the over-temperature protector and the temperature controller jump, reset it to power, check whether the leakage switch can be reset, whether the water heater can work normally, or remove the over-temperature protector and temperature controller and measure the continuity with a multimeter. Whether it is normal, if it is normal, it can be judged that the temperature setting of the over-temperature protector or the temperature controller may change and needs to be replaced. Because there is no instrument to detect the temperature setting, in order to avoid the same fault reappearing, it is best to return the over-temperature protector and temperature controller to the company for testing by special instruments. 2 Check whether the insulation of the internal connection line of the water heater is damaged and cause short circuit leakage. Unplug the connection line between the electric heating tube and the indicator light. Use a multimeter to check that there should be no connection between the connecting lines. If there is any connection, replace or bandage it. Check whether the components are normal according to the component detection method. 3 Check the leakage protection power cord, disconnect the leakage protection power cord connection, pay attention to the contact of each line, plug in the power supply, press the leakage switch reset button to press the reset, if not reset, determine the leakage protection power cord The leakage device is broken and needs to be replaced.

Electric water heater failure phenomenon 2: Leakage protection power cord indicator light is on, the water heater power indicator light is not bright, no hot water

Reason analysis: 1 Whether the temperature controller has been opened 2 plug connector is loose or broken 3 is the working voltage of each component is normal

Maintenance method: 1 Check if the temperature controller knob is adjusted to the highest temperature position. 2 Check if the power cord and each cable are loose or disconnected. 3 Use the multimeter AC250V file to measure whether the power line, each connection line and components have a normal working voltage of 220V.

Fault phenomenon 3: Leakage protection power cord indicator light is on, the water heater indicator is not lit, there is hot water

Reason analysis: 1 temperature controller has been insulated 2 power indicator line is connected well 3 indicator voltage is normal

Maintenance method: 1 Check if the temperature controller is kept warm, and let the hot water flow out for about 5 minutes to check if the indicator light is on. 2 Check if the indicator cable is connected properly, whether it is loose or disconnected. 3 Check whether the indicator light has 220V or not. Use the universal meter AC250V to measure whether the red and blue wire inserts have 220V voltage. If there is voltage but the indicator light is off, it is determined that the indicator light has burned out and needs to be replaced.

Fault phenomenon 4: The water heater power indicator light is on, no hot water

Analysis of the cause: 1 The water outlet pipe of the mixing valve is blocked. 2 The heating pipe connection plug is disconnected, the 3 electric heating pipe has no working voltage, and the electric heating pipe is blown.

Maintenance method: 1 Touch the water supply pipe of the mixing valve and the position of the heating plate with or without heat. If the heating time is too short, unscrew the outlet pipe to see if there is hot water. 2 Check whether the electric heating pipe connection plug is loose or disconnected, and use a multimeter to measure the connection line for conduction. 3 Check whether the electric heating tube has a working voltage of 220V, and measure the two terminals of the electric heating tube and the connecting line with or without working voltage of 220V with the multimeter AC250V file. 4 Check whether the electric heating tube burns the heating wire, and use a multimeter to check whether the electric heating tube is normal according to the component detection method.

Electric water heater purchase strategy

1, when you first look at the capacity to buy storage water heaters, you must first determine the size of the water heater. The choice of water heater capacity depends mainly on factors such as the size of the household and the amount of hot water. Generally speaking, if one person is used for bathing, the electric water heater with a capacity of 30-40 liters can be selected; for 2-3 people, the 40-50 liter electric water heater should be purchased for continuous bathing; for 3-5 people for continuous bathing, 70 is required. -100 liter electric water heater. In addition, the larger the size of the external size is generally larger, so the size of the installation space needs to be considered.

2, view the inner tank of the electric water heater is the key part of the storage type electric water heater, it can be said that it is the "heart", the performance and quality of the liner directly determines the service life of the storage type electric water heater. At present, there are three types of electric water heaters on the market: galvanized liners, stainless steel liners, and enamel liners. From the aspects of anti-corrosion, heat preservation and service life, the enamel liner is the best.

3, pay attention to the safety of electric water heaters Electric water heaters as a power product, its safety directly determines the user's personal safety. At present, our electricity consumption environment is still not very satisfactory. There are often accidents in which electric water heaters leak electricity and hurt people. The electric water heater leakage protection is extremely important. At present, the anti-electric wall technology is a relatively reliable anti-leakage protection measure, and this technology has been included in the new national standard for electric water heaters. When purchasing, check whether the product has safety technology such as anti-electric wall.

4, choose energy efficient, energy-saving products, electric water heaters use high frequency, energy-saving water heaters save money. The energy efficiency rating system of water storage type electric water heaters has been implemented. According to the regulations, all kinds of water storage type electric water heaters should be labeled with energy efficiency stickers. The energy efficiency rating of water storage type electric water heaters is divided into 1-5 levels, of which level 1 is the highest, level 2 is the second, level 5 is the lowest, and the energy efficiency limit value is the threshold for market access. Products below level 5 will not be available. Market sales.

5, other purchase considerations In order to prevent the purchase of inferior products, when buying a water heater, it is best to choose a brand of products, to a reputable store to buy; when purchasing, pay attention to check the product quality inspection certificate; in addition, pay attention to Check the service of the product, pay attention to the warranty period of the product, whether to provide on-site installation, free maintenance and other services.
