Understanding Instant Intelligent thermostatic water heater The knowledge of basic working principles and common fault diagnosis of the system will bring a lot of convenience to family life. Since electrified products can have problems and failures anytime and anywhere, a simple understanding of some common sense can help us find problems in time and avoid many detours. Of course, for some problems that are not common or can not be solved, we must consult professionals, and we cannot do this blindly to avoid unnecessary losses and injuries.

Although there are many manufacturers, brands and models of instant intelligent thermostatic water heaters, and there are also differences between LPG and pipeline gas, the basic working principle is the same. Usually, the hot water faucet or shower switch is turned on, and the water enters the water heater from the tap pipe, flows through the heating copper pipe, is heated, and then flows out to get hot water. Since gas leakage is very dangerous, the water heater has two gates for controlling gas, one is the water control valve, and the other is the solenoid valve. When there is enough pressure of water flowing through the internal water pipe, the water pressure will push the cross bar to open the water control valve, and the gas can pass the first check point.

The crossbar will also turn on the main switch of the water control power supply of the lighter at the same time. The lighter will be powered on to work, start ignition, and turn on the solenoid valve at the same time. The solenoid valve is also opened, and the gas can enter the combustion plate through the second check point, meet the spark and burn, and then start to boil water. The above is the basic startup process. The most common failure is not combustion. When encountering this problem, it can be inferred according to the following ideas:

If the water pressure is normal, but the water pressure of the hot water faucet or shower is abnormal, it may be that the hot water faucet or shower is dirty and blocked, just clean it and restore the normal water pressure.

If the water pressure at the outlet is normal, it depends on whether it is on fire. If you cannot hear the sound of sparks, first check the battery for poor contact or no electricity. If the battery is OK, the main switch of the water control power supply is in poor contact. When opening the shell of the water heater, it is easy to see that the main water control power switch is installed under the water heater. It is made of black plastic. There is a small iron plate on the right with a small contact pressed on it. Close when pressed, open when released. You can use your nails to break the small iron sheet to the right, and then release the switch manually. If normal, it will ignite immediately. If there is no ignition, most switches are damaged, and the damage rate of this switch is very high. The switch is not expensive, just buy and replace it.
