Electric water heater descaling tricks teach you how to easily remove limescale from electric water heaters without spending money.

Hello, the water heater produces scale, which needs to be disassembled by professionals, and the magnesium rod should be replaced regularly, which can effectively reduce the generation of scale.

It should be cleaned by a professional, otherwise it is easy to be dangerous.

The method of cleaning limescale in an electric water heater is as follows:

Prepare materials: socket, screwdriver, wrench.

1. Unplug the power supply of the water heater and turn off the home water inlet valve.

2. Use a screwdriver to open the sewage outlet.

3. After unscrewing the only screw, be careful not to pull the cover off with brute force, and gently push it in the direction of the screw on the sewage outlet.

4. Use a sleeve to remove the magnesium rod in the sewage outlet, 5. The water flows out, but the water flow is small at this time.

6. Unscrew the hot water outlet pipe of the water heater with a wrench, the water flow at the sewage outlet will be accelerated, and the dirt will be discharged until the water inside the water heater is drained clean.

7. Block the hot water outlet pipe, open the water valve, let the water from the water pipe enter the water heater and then discharge from the sewage outlet, and the dirt will be discharged again.

8. See that there is no more dirt discharged from the sewage outlet, and the water heater is preliminarily cleaned.

9. Close the sluice, tighten the hot water outlet, clean the dirt on the magnesium rod and put it back into the water heater, and tighten the screws. Close the sewage outlet cover, 10. Open the sluice, fill the water heater and then energize the water heater, check whether the water heater is running normally and whether there is any water leakage, and if not, it will be marked that the cleaning is successful.

Answer 1: Unplug the electric water heater, close the two angle valves, unscrew the nuts of the hot water inlet, and block the hot water inlet; 2. Unscrew the cold water port, connect the hose to drain the remaining water, remove the cover on the side of the inner tank of the water heater, and remove the heater gasket, heater and thermostat; 3. Open the cold water inlet valve, rinse the inside, and then brush with a brush, and clean the scale on the heating pipe at the same time; 4. After rinsing with clean water repeatedly, install it back in reverse direction according to the disassembly.

Question: I've cleaned it up, but I can't get hot water.

Answer: Install and plug in after cleaning, be careful not to leak electricity, because it has just been enabled, so you should leave a time to heat the water heater, and wait for the pointer on the water heater to reach the red grid or the temperature display is up to standard.

Asking questions still doesn't come out of the hot water.

If it doesn't light up, there may be a problem with the thermostat. Under normal circumstances, an electric water heater has dual thermostats, that is, room temperature control, which controls the display and control of the water temperature of the water heater; Over-temperature temperature control to avoid tripping when there is a problem with room temperature control. If the temperature control trips, it will directly cause the electric water heater to be unable to boil hot water, so that there will be no hot water.

The scale treatment method of electric water heater is:

1. Cut off the power supply, if there is a special drain nut on the water tank, remove the nut and drain the water in the water tank, add tap water to the water tank after discharge, and then release it, so that the scale will be removed several times.

2. If there is no special drain nut, remove the water pipe with a safety valve, drain all the water in the water tank, and then add water and discharge water repeatedly, and the scale of the electric water heater can be removed when there is no scale in the water to be discharged.

3. You can contact the after-sales service department, please ask professionals to operate once on site, and it is best to install magnesium rods in the water tank, and the generation of scale will be reduced, so as to remove the scale of the electric water heater.

Here's how:

The first step is to release the water. Remove the power plug, then close the cold water angle valve, pull open the overflow valve, and release hot water from the hot water switch. When the hot water stops flowing, close the hot water angle valve, remove the hot water angle valve connection screws, and let the water in the water heater flow out of the overflow pipe slowly.

The second step, after the water is discharged, you can remove the water heater, which is hung on the wall and taken off with both hands. Then remove the four screws on the left hand side of the water heater and remove the baffle to reveal the internal circuit board and heating pipe.

The third step is to remove the terminal plug-in, which can be pulled by hand. Remove the grounding cable, water level sensor and temperature sensing cable.

Step 4: Unscrew the five screws to remove the heating tube. It took a lot of effort in this link, and I once wanted to give up, because I didn't know the specific structure inside, and I couldn't pull it and didn't dare to push too hard. In fact, it is the scale that prevents the hot water pipe from being taken out smoothly, just use a little force, and the back bend should be sideways and smooth.

Step 5: Clean the heating tube and cylinder block.

Sixth, this is the cleaning of scale, much less than imagined, the outer diameter of the heating pipe flange is 125mm, if there is a need to change it can be bought online.

Step 7: Assemble the machine back in reverse order of disassembly, then fill it with water, plug in the power supply, and test the machine.

Rust stains in electric water heaters can be removed by:

1.Wash with vinegar: Pour vinegar into the water tank, about half of the water tank's liquid volume, wait for 15-20 minutes, drain the vinegar water, and rinse it several times with clean water.

2.Wash with citric acid: Citric acid has a good cleaning effect, dissolve citric acid in hot water, then pour it into the water tank, wait for about 30 minutes to drain the cleaning solution, rinse with water.

3.Use electric water heater cleaner: There are special electric water heater cleaners on the market, which are similar to vinegar cleaning.

It should be noted that the power supply needs to be cut off during cleaning to avoid electric shock accidents. In addition, it is necessary to rinse repeatedly after cleaning to ensure that there is no residual cleaning solution in the tank, otherwise it may affect human health.

1.It is very important to remember to unplug the power cord before cleaning the electric water heater, as it is related to the safety of the cleaning.

2.At the same time, close the cold water valve, then use a wrench to remove the pneumatic valve device, connect the plastic pipe, and drain the water from the water tank in the water heater.

3.Then open the pressure relief valve, rotate it vertically 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 the inner tank will be flushed through the hot water pipe.

At this time, you will notice that a lot of turbid water will flow out of the inner tank. Repeatedly, the inner tank of the water heater can be effectively cleaned.

4.Finally, the valve was restored to its original appearance, the pipe was connected to the hot water valve, and both valves were opened. If there is water coming out of the faucet or shower, the water is full and can be used normally again.

Water Heater Maintenance:

1.Carefully detect and eliminate safety performance and other potential hidden dangers; Users who do not turn off the power supply of the water heater all year round should always check whether the water heater is normal, and send it to the maintenance point for maintenance in time if there is any abnormality.

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

3.Electric water heaters 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 the water, which will also affect the safety performance of the electric water heater.

4.After the electric water heater is used for a period of time, it is easy to accumulate scale on the heating pipe, which seriously affects the heating efficiency and consumes electric energy. Therefore, general electric water heaters need to maintain the heating element regularly.

Step 1: Unplug the socket and close the two triangle valves. Step 2:

Unscrew the nut of the hot water inlet to block the hot water inlet and prevent the water from the water heater from flowing out. At the same time, unscrew the nut of the cold water inlet, connect the hose to drain the water, until there is no water flowing out of the cold water inlet, and the water heater of 50L drains water for about 1 hour. Step 3:

Remove the hose connected to the cold water inlet, connect one end of the hose to the hot water inlet, and the other end to the faucet, open the faucet and fill the water for 1 minute, and plug the cold water inlet, let the cold water in the inner tank for a while longer, then open the cold water inlet to drain the water, repeat several times until the discharged water is clean. Step 4: Screw on the nuts of the cold water port and hot water port, open the triangle valve, and turn on the hot water from the water heater faucet, and close it after the water flows out.
