Maintenance method of household appliance water heater

Water heater is one of the indispensable household appliances in family life. After the water heater is selected, it will be used every day, and there will be some faults after being used for a long time. In order to ensure the normal use of water heaters, we need to know how to maintain domestic water heaters. Let's take a look at the maintenance methods of domestic water heaters, and what maintenance precautions are there.

What is the maintenance method of household appliance water heater?

1. First of all, we need to see whether the indicator light on the leakage protector is on, which is the first step of electric water heater maintenance. If the electric water heater at home is not equipped with a leakage protection switch, you should pay attention to the indicator light on the shell of the water heater. If the light is not on, it may be that the power supply voltage is not output, or the leakage protector is broken.

2. For the two results of the first step, we can use a multimeter to judge. If there is voltage output, the protector is broken, and vice versa.

Of course, if the light is on, you can open the cover of the water heater with screws and check whether there is any fault in the internal structure. A thermostat is connected to the cover of the water heater. You can also use a multimeter to check if this thing is broken. If it can't be opened all the time, there may be something wrong with the mechanical text.

The fourth step of electric water heater maintenance is to check another thermostat. Generally, water heaters have two thermostats to adjust and keep them in a normally open state. We just need to measure whether they can be turned on.

5. As an electrical appliance with high power consumption, sometimes the connecting wire is easy to age or break. When it is determined that no problems are found in the above maintenance steps, it is necessary to check whether the terminals and connectors of the connecting wires are burnt out, and replace the connecting wires with new ones immediately after finding them, so as to ensure the normal operation of the electric water heater.

6. If the above maintenance methods can't find the cause of the failure, it will be more difficult. The sixth step is the maintenance method of electric water heater, which is a more troublesome and critical step. At this time, we have to judge whether the heating pipe is burnt out or not, and we can also use a multimeter to check it. The method is to adjust the resistance of the multimeter to 200 ohms, generally about 1000W45 ohms and about 1500W about 30 ohms.

Matters needing attention in maintenance of domestic water heater

1, the specific steps are to determine the installation position, and then mark it with a pen, so that it will not deviate from our direction, then punch holes with an impact drill and place expansion bolts, or tie the water heater to a fixture with thin iron wire, as long as it is firm.

2. The correct method must cooperate with our careful observation and detection of hydropower links, and it can be used safely after installation. There will be no danger. See if there is any water leakage. If everything is all right, you can try electrifying it.

3. Grounding wire, as the saying goes, protecting electrical equipment is also an electricity-proof wall to ensure the safety of shower. Only when it stabilizes us can we use it more safely. See if there is a ground wire connection at home, and hit the depth below 1.5 meters underground. Nail a nail in the hole and pour some water into it.

There are many details that you need to know when using the water heater. Of course, it is also important to learn to maintain when buying. The above is the maintenance method and maintenance precautions of household water heaters introduced by Bian Xiao. It's over.
