Detailed maintenance steps of electric water heater maintenance method

Lead: Every household has an electric water heater, which has become one of the necessary household appliances in our life. When there is no electric water heater, people always boil water and take a bath by themselves. Now that we have an electric water heater, we can take a bath directly by turning on the switch of the water heater, which saves us the time of boiling water. If the electric water heater is broken, it's really depressing. What if the electric water heater is broken? Below, Bian Xiao sorted out the maintenance methods of electric water heaters for everyone. Let's take a look.

Maintenance steps of electric water heater

1. Most electrical appliances have power indicator lights, and so do water heaters. First, check whether the power indicator light on the leakage protector next to the socket is on. The indicator light without leakage protection switch is on the shell of the water heater. If the indicator light is off, there are two possibilities. One is that the power supply has no voltage output, and the other is that the leakage protector is damaged!

Now we need to check whether the power supply has voltage output. (Measured with multimeter AC voltage range) If there is a voltage output of 220V, then we can judge that the leakage protector is broken, and replace some leakage protectors to eliminate the fault! If there is no voltage output to detect the power line.

If the power indicator light is on, then we will go to the next step and open the cover on the side of the water heater with a screwdriver. Most water heaters are special screws, triangular and diamond-shaped. We have to prepare a special screwdriver to open them!

After opening the lid, we can see that there is a mechanical thermostat connected with the lid. This accessory rings most easily. Now we need to check whether it is broken. The multimeter jumps to the on position, and the pins are connected to the two terminals of the thermostat. Then, turn the temperature control knob from high to low. If the multimeter is found to be non-conductive, judge that the temperature control is damaged, replace it, and troubleshoot it. If the multimeter indicates that the on-off is normal, it is judged that there is no damage, and the next step is carried out.

5. Next, measure another temperature control? This temperature control is generally kept in a normally open state. When the temperature control of the electric water heater is out of control, it only provides upper limit temperature protection, so we only need to measure whether it is on or not to prove that it is normal. If it is not on, it proves that it is damaged. Replace it to eliminate the abnormality!

6. Because the water heater is a high-power electrical appliance, the cross section of the connecting wire often ages and melts. At this time, we will know whether the terminal and connector of the main connecting line are burnt out, and it would be nice to change one.

7. If all the above are normal, the most critical and difficult thing is to judge whether the heating pipe is burnt out, which can also measure whether it is damaged. The multimeter is adjusted to a resistance of 200 ohms, which is generally about 1000W45 ohms, 1500W is about 30 ohms, and 2000W is about 22 ohms. If the numerical difference is too large, the heating pipe must be replaced.

Conclusion: The traditional wall-mounted installation of electric water heater is influenced by the hollow wall, which is easy to fall off and unsafe. The "vat" is naked and unsightly, occupying a lot of space. Some manufacturers began to consider building integration or home integration products, such as integrated water heaters on the market. Integrated water heater is an integrated design of water heater and bathroom cabinet, which is very different from traditional water heater in design concept. This is a brand-new attempt. Consider choosing an integrated electric water heater before decorating the bathroom.
