This is a problem I often encounter
First, check whether the solenoid valve is energized/if it is energized, firstly there is a slight vibration, and secondly, after a few minutes, touch it with your hands. There will be a slight warm feeling at the bottom/if this is normal:
Second, turn off the water supply first. Isn't there a copper wire cover under the solenoid valve? Use a key to open it and you will see a small piece of plastic. The mesh is the filter/then remove it with your fingers, rinse it then put it back in for a test if it can let water through. if it still can't let water pass:
Third, remove the solenoid valve as a whole. Remove it, turn on the electricity, hold the water plug end with your mouth and blow air hard into it. .As long as the air is ventilated, the water will flow.
Four, if the above methods fail, there are only two left. HeThere are three possibilities: first, the solenoid coil is shorted; the inlet and outlet water stop switches at both ends of the solenoid valve are blocked. It requires accessories and professional knowledge to solve the problem. If you do not meet these conditions, you should consider replacing it with a new one. 20 to 30 yuan. If the water still doesn't flow, it's not a problem with the solenoid valve
This is the method I've used for years, and it's also the only method

< p>The operation is as follows:
1. The solar water heater sensor has two parts: water level and water temperature, each with two wires and a total of 4 wires.
2. They cannot be connected together randomly, otherwise the water temperature and meter water temperature display will be incorrect.
3. Generally speaking, the square connector of the sensorThe meter has 4 small holes, corresponding to the 4 pins of the meter. Bad connections include: Temperature display.
4. If there is no water level, the temperature will not be displayed. If there is water level, there will be no temperature and there will be no water level display. You can swap the 4 wires repeatedly until the temperature and water level are normal.

Cleaning the gas water heater
< p>1. For gas water heaters, if the housing and filter are relatively undirty, simply use a damp cloth to remove the dirt. However, if the stains are heavy, the user should use detergent to clean them thoroughly. After long-term use, a lot of scale and dirt will accumulate on the gas water heater filter. Then the user needs to unscrew the robiwater, remove the filter and clean it.2. Water reservoir. Under normal circumstances, the water tank is an easily clogged part. Next, the user should carefully check whether there is any accumulation of scale, dirt, etc. cleaning. If so, you can use thread to remove it. But if you don't know how to clean it, you can ask professional after-sales maintenance personnel to clean it.
3. The induction needle and the ignition needle. The induction needle and the ignition needle are important factors that affect the temperature of gas water heaters. If you find that the ignition effect is poor in daily life, it may be caused by this. of the appearance of the induction needle or ignition needle problem. The solution is: wipe gently when cleaning, do not forceDo not press too hard to avoid bending the needle.
4. THEs gas lines. Gas lines are usually made of rubber. The obvious downside is that they are very easy to fill with dirt, and many users choose to install them when installing water heaters. is out of the kitchen, the problem of oil stains will become very significant. Users can use detergent to clean oil stains on gas lines.
