How to clean the electric water heater?

1. Remember to unplug the power cord before cleaning the electric water heater, which is very important because it is related to the safety of cleaning.

2. Close the cold water valve at the same time, then remove the pneumatic valve device with a wrench, connect the plastic pipe, and drain the water in the water tank of the water heater.

3. Then open the pressure relief valve, and rotate it vertically by 90 degrees with a wrench, and the water inside will flow out. After the water inside is cleaned, it will be connected to the hot water pipe and rushed into the liner through the hot water pipe. At this time, you will find that a lot of turbid water will flow out of the inner tank. Repeated use can effectively clean the inner container of water heater.

4. Finally, restore the valve to its original appearance, connect the pipeline with the hot water valve, and then open the two valves. If there is water flowing out of the faucet or shower, it means that the water is full and can be used normally again.

Maintenance of water heater:

1. Carefully detect and eliminate safety performance and other potential hazards; Users who don't turn off the power of the water heater all the year round should always check whether the water heater is normal and send it to the maintenance point in time if it is abnormal.

2. When the water heater is in normal use, replace the thermostat and water heater at the designated maintenance point every three years. Replace the expired water heater in time.

The electric water heater should be inspected and maintained once a year, because there are more or less impurities in the water. After the water heater is used for a period of time, it is easy to be corroded by alkaline substances in water, which will also affect the safety performance of electric water heaters.

4. After the electric water heater is used for a period of time, it is easy to accumulate scale on the heating tube, which seriously affects the heating efficiency and consumes electricity. Therefore, general electric water heaters need regular maintenance of heating tubes.
