The gas water heater is the first generation of water heater in China, which brings great convenience to the provision of hot water for people's life. However, the gas water heater sometimes fails to ignite, which is quite inconvenient. Today, I will introduce the faults and repair methods of the gas water heater to you. In addition, I will also explain in detail the cleaning and maintenance of the gas water heater, so that you can have a comprehensive understanding of the knowledge of the gas water heater

the gas water heater is the first generation of water heater in China, which brings great convenience to the provision of hot water for people's life. However, the gas water heater sometimes fails to ignite, which is quite inconvenient. Today, I will introduce the repair methods of the gas water heater, and also explain in detail the cleaning and maintenance of the gas water heater, so that you can have a comprehensive understanding of the knowledge of the gas water heater

gas water heater failure and repair methods

1. The ignition is not smooth

the main reason why the ignition is difficult or does not ignite is the carbon deposition between the fire nozzle and the electric heater, or the fouling of the water valve filter screen. Cleaning method: check the fire nozzle and electric heater. If carbon deposits are found, clean them up; If the water valve filter screen is dirty, unscrew the water inlet pipe, take out the filter screen and clean it with water, or clean it directly on the pipe, and then install the water inlet pipe after cleaning

2. Incomplete extinguishment

incomplete extinguishment will lead to the increase of harmful gases and serious environmental pollution. The main reason is the infarction of the thermal AC and the main extinguishment. Cleaning method: check that the heat exchanger enters the extinguisher, and stop cleaning to make it unobstructed

3. The air valve cannot be opened

after the water valve is opened, as long as there is an open fire, there is no fire for boiling water. The main reason is that the tympanic membrane of the air outlet nozzle breaks, and the air valve cannot be pushed open. Cleaning method: buy a new tympanic membrane and replace it. During the replacement process, avoid installing the hollow screws on the tympanic membrane upside down, otherwise, replace the new tympanic membrane and do not open the air valve

4. The copper tube with burning leakage

is the most vulnerable to damage, which is the copper tube directly above the open flame. The main reason is that the management wall of the copper tube was burned into a flaw under the condition of water supply failure, low water pressure or long-term open fire. Cleaning method: when in urgent need, temporarily use a fuse to plug the eye. After use, remove the gas water heater, drain the water in the water pipe, and weld the leakage hole firmly with an electric soldering iron. In order that the place will not be burned out in the future, an iron sheet can be installed at the copper pipe directly opposite the long-term open fire to block the long-term open fire. In this way, the copper tubes here can be named for 3-5 years

5. Fouling of heat storage sheet

fouling of heat storage sheet will affect heat absorption and ventilation. The main reason is that it takes a long time to use and the indoor air is not circulating. Sweeping method: remove the ash scale between the heat storage blades. If the ash scale is too thick, grind the hacksaw blade into an inclined knife shape, scrape the ash scale quietly, and blow the scraped ash scale clean with a bicycle air pump. Finally, you need a hacksaw blade or other tools to move the heat storage blades to the average distribution, so as not to affect the heat storage and ventilation

cleaning and maintenance of gas water heater

1. The external cleaning of gas water heater only needs to be wiped with a soft rag frequently

2. Remove the carbon residue and scale at the burner. Generally speaking, the carbon deposits generated in the main nozzle, auxiliary nozzle and flue are hard and dense, firmly bonded to the metal, and are a mixture of oil coke, asphaltene and ash powder, which is extremely difficult to remove; When cleaning, put the parts with carbon deposition into the cleaning solution with carbon remover, heat the cleaning solution to 80-90 ℃ and soak 2— 3h, until the carbon deposit softens, and then wipe it with a brush or old cloth; Finally, rinse it with hot water and dry it

3. When using carbon remover, it cannot be used to clean the residual carbon on the heat exchanger to avoid damaging the heat absorption and heat reflection coating layer on the heat exchanger

4. Dust and dust on the heat exchanger between fins can be wiped with a rag or blown away with a skin blower

5. Regularly check whether the gas supply pipeline (rubber hose) is in good condition, whether there is aging, crack, leakage and other phenomena, and deal with them in time if any adverse phenomena are found

6. Always pay attention to whether there is water leakage or air leakage, so as to deal with it in time

7. Always pay attention to whether the flame at the fire mouth becomes smaller and deal with it in time; Pay attention to whether the flame is normal combustion during use

8. Often wipe the dirt on the surface of the shell with a wet cloth, and then wipe it dry with a dry cloth. The dirt that is not easy to remove can be wiped with neutral detergent

9. Strong detergent and gasoline should not be used to clean plastic products, printing surfaces, spraying surfaces, etc

10. When there is dirt at the ignition electrode, wipe it with a dry cloth to ensure the ignition quality
