Electric water heater cleaning method steps and parts**:

Step 1: First, turn off the electric water heater, open the hot water faucet to drain the water, open the pressure relief valve, and close the cold water valve;

Step 2: Then use a screwdriver to open the cover on the outside of the sewage outlet; Use a wrench to twist the screw of the sewage outlet, take out the magnesium rod and drain the internal sewage and impurities;

Step 3: Open the cold water inlet valve, flush the inside, and close the cold water inlet valve after no sewage is discharged;

Step 4: Open the prepared cleaning agent for the electric water heater, inject the cleaning agent into the drain of the electric water heater with the supplied syringe barrel, and tighten the drain. Open the cold water inlet valve, fill the electric water heater with water, and close the hot water valve for a certain period of time according to the instructions of the cleaning agent;

Step 5: When the special cleaning agent in the water heater and the water soaking time is reached, open the hot water valve and twist the sewage outlet to drain the water, when the water is cleaned, turn on the cold water again and rinse the inside until there is no foam;

Step 6: Replace the new magnesium rod for the electric water heater and the sealant gasket and nut of the sewage outlet, tighten it with a wrench to ensure that it does not leak and cover the outer cover; Re-add water, and heat, the first time to add water can not be used, to heat to about 60 degrees, you can turn off the power and discharge, and then add water, you can use normally.

Note: When replacing the magnesium rod to clean the inside, the power should be cut off in advance to ensure personal safety.

1. Before cleaning the water heater scale, be sure to stop the water heater from heating in any form one night in advance.

2. Before cleaning, disconnect the power supply, unplug to ensure safety, and then close the two angle valves.

3. Unscrew the nut of the hot water outlet and block the hot water outlet to prevent the water from flowing out of the water heater. At the same time, unscrew the cold water inlet, connect the hose to drain the water, and wait until there is no water to drain out of the cold water inlet and the water flow is clean.

4. Brush the inside of the water heater with a brush from above, so that you can better brush off the impurities, pour out the cleaned scale, and rinse the inner tank of the water heater repeatedly with clean water. At the same time, clean the limescale from the heating tubes. Remove the heating pipe as well, there is a thick scale on the heating pipe of the water heater, which will shorten the life of the water heater.

4. Disassemble the metal hose joint at the hot water pipe, at this time there will be water flowing out of the pressure relief valve, and when there is no more water flowing out of the pressure relief port, the water in the inner tank will basically flow out.

5. Next, connect the metal hose of the cold water pipeline to the hot water outlet of the water heater, open the cold water angle valve, and let the cold water rush into the inner tank of the water heater from the pipeline.

The scale inside the water heater is formed due to the crystallization of calcium and magnesium ions in the water during the heating process.
