1. What is the reason why the water heater won't catch fire?
1, the reason why it can't catch fire is that the gas type doesn't match. Phenomenon: there is ignition sound, no electric spark. It is also a very important aspect, the solution: if the liquefied gas water heater is connected with natural gas, it needs to be changed into a natural gas water heater before it can be connected.
2. The reasons for non-ignition are: solenoid valve failure: it is also known that there is only ignition sound when igniting. If there is no magnetic sound absorption of the solenoid valve, it may be that the solenoid valve is damaged or aging; Too high or too low air pressure can also lead to misfire; The solenoid valve has stolen goods, so the gas can't escape and it won't catch fire. Solution: If the solenoid valve is aging, replace it; If there is air pressure problem, replace it with a new cylinder; If the air valve has stolen goods, clean it and repair the circuit problem.
3. The reason of misfire is that the water-gas linkage device is faulty. They are all very important reasons, phenomena: no ignition sound and electric spark. Solution: Check whether the inner eardrum of the water-gas linkage valve is aging or damaged. If the microswitch cannot be pushed, replace the water-gas linkage valve or repair it.
Second, how to choose a water heater
1. First of all, the electric water heater is an important product of household bath water, which should be taken into account. At present, there are many brands in the electric water heater market, so how to choose a safe and durable electric water heater is very important. Just like CRT, the key component of TV, the key component of electric water heater is the inner container, and its safety and durability depend on the quality of the inner container.
Secondly, some electric water heaters have slow heating efficiency. This aspect is prone to scale. This kind of electric water heater consumes electricity and is not durable. At present, the Jingui special care system which can solve the problem of electric water heater liner in the market, American patent technology (patent number: US6303 183), consists of Jingui liner and Jingui heating rod. The precious coating on the surface of the liner can effectively protect the liner from corrosion, protect the liner for a long time and prolong its service life. A.O. Smith recently upgraded the "Jingui Special Care System" and added the technology of replacing magnesium rods, which can continuously protect the inner container and save money and trouble.
Finally, the service life of electric water heater is usually 6-8 years, which can also give us a good use. It is best to buy an electric water heater with a leakage protection device. Anti-dry-burning protector, water inlet physical anti-electricity wall+water outlet physical anti-electricity wall and over-temperature sensor are equally important.
When there is a problem with the use of the water heater, we should also understand the reasons, so that we can have a good treatment.
