The gas water heater can be lit and extinguished in a while, and it smells of gas

If the water pressure at the outlet is normal, it depends on whether the fire is ignited. If you can't hear the sound of ignition, first see whether the battery is in poor contact or there is no electricity, and if there is no problem with the battery, most of them are poor contact with the main switch of water control. Open the water heater shell, it is easy to see the water control power main switch installed in the lower part of the water heater, black plastic, and there is a small iron piece on the right side pressing a small contact, pressing is off, loosening is on.

You can use your fingernails to break a small piece of iron to the right, artificially loosen the switch, and it will be ignited immediately if it is normal, if there is no ignition, most of the switches are broken, and the damage rate of this switch is very high. This switch is not expensive, just buy one and replace it.

If you hear the sound of a fire, it depends on whether it burns and goes out, or if there is no movement at all. If it is the former, it means that the solenoid valve is opened for a while, and then closed again, and a small "tuo" sound of the solenoid valve opening can generally be heard close to the water heater. If it is the latter, the solenoid valve is generally not opened at all, most of the lighters are broken, and you can replace one, and the solenoid valve will generally not be damaged, that is, the damage rate is low.

However, because the inferior water heater uses inferior materials to make the solenoid valve pull rod, it is easy to rust, and the pull rod movement is not smooth, resulting in the solenoid valve can not be opened, but it can be disassembled to scrape the rust and put the motorcycle oil, and the sliding and sliding can return to normal. Extinguishing once burned means that the lighter can work normally all at once. The occurrence of this phenomenon is related to the energy-saving design of the lighter.

Those who have studied electrical engineering will know that an electromagnet needs a large current when it is started, and only a small maintenance current is required after starting. There are two currents when the lighter controls the opening of the solenoid valve, and the solenoid valve also has two sets of working coils. When it is first started, there is generally a current flowing out of both channels, so that the solenoid valve can be opened smoothly, and after opening, there is no need for such a large current, so the one called the starting circuit is turned off.

The starting current is generally large, and the solenoid valve can be activated alone. At this point, everyone should understand that it will be extinguished after burning, and it should be a problem to maintain the current. The maintenance circuit is abnormal either because the battery voltage is too low, or there is a problem with the lighter, change it.

1--The water pressure is unstable, 2--The water pressure glue bowl is broken, 3--- The battery is not enough or the relevant open line is not in good contact, 4-The ignition is poor. (including ignition needle or detection needle ablation).

The above are the 4 reasons for poor ignition of gas water heaters.

Continued investigation.

It's OK to turn on the switch that controls the water a little bigger, and when you adjust it, you need to control the gas as much as you want to control the water, and there will be no such situation.

1. Using the water heater for too long: the internal connector is loose. Take a new one and tighten it or replace it with another one.

2. The igniter is broken: The water heater is a natural reaction after ignition, but it will go out again in a few seconds or so, mainly because the heat induction is not enough. The igniter had to be replaced.

3. The battery is dead: the battery must be replaced.

4. Sometimes this phenomenon will occur because of the backfilling of the smoke exhaust pipe, as long as the hood is installed at the smoke exhaust port, the problem can be solved.

5. If it has been used for more than two years, it may also be that there is a problem with the induction needle of the water heater and the conductive function is not good, so it must be replaced.

Scale accumulation on the inner wall of the water heater: After the water heater has been used for a long time, the inner wall of the water heater will also adhere to the scale, and the scale will be too large and too thick, which will seriously cause the hot water pipe to be blocked.

Ion needle failure: The ion needle is also the key to the ignition of the water heater, once it burns out, deforms or shifts the position, it will cause the water heater to not ignite.

Solenoid valve damage: If the solenoid valve is aging and the plug is wrong, there will be a fault that the water heater will automatically stop ignition, open for a while and then turn off, and the solution is to replace the solenoid valve in time.

Precautions for the use of gas water heaters.

It should be noted that gas water heaters are all strong exhaust type, and they need to be exhausted outside, and this gas generally has a certain temperature, so the exhaust pipes of gas water heaters are metal, and the metal exhaust pipes are also warm in daily use, so the installation of exhaust pipes should pay attention to avoid the exhaust pipes of range hoods that are generally in the ceiling, because the exhaust pipes of range hoods are plastic, and they are easy to age and damage when heated locally for a long time.

Some models of gas water heaters can be wrapped into the cabinet, but some models of gas water heaters can be wrapped into the cabinet will make it burn inadequately, and even frequently extinguish the fire, so you need to consult a professional. Even if the gas water heater can be wrapped into the cabinet, it should be ventilated as much as possible, for example, the cabinet wall cabinet should not be made of top and bottom plates, and shutters should be installed.

Fault causes and treatment methods for gas water heaters that turn off in use:

1. The valves of the gas are not all opened. (Solution: Open all the gas valves.)

2. The gas pressure is not suitable and too low. Solution: Turn the hot water brake on and off continuously until it catches fire.

Note: After turning off the hot water switch, you should wait for more than 5s before turning it on again. ）

3. The water pressure of the cold water supply is too low. (Solution: Check the water pressure.) If the water pressure is activated, the water volume control screw under the gas valve body should be adjusted to reduce the water output. ）

4. Safety device action. (Solution: Please refer to the instructions on the manual for handling the safety device operation.) ）

5. The heat exchanger is blocked. (Solution: Clean up the carbon deposits in the heat exchanger.)

6. The water controller is faulty. (Solution: Replace the controller.)

7. The pulser is faulty. (Solution: Replace the pulser.)

8. The lead wire is loose. (Solution: Properly connect the loose lead.)

9. Solenoid valve failure. (Solution: Replace the solenoid valve.)

10. Flame probe failure. (Solution: Adjust the probe position.) ）

What is the reason why the gas water heater turns on the fire and then goes out a few seconds later? The repair is very simple, the master will teach you.

The liquefied gas pressure is too small, and the cylinder pressure reducing valve needs to be adjusted to a large state. If pipeline gas is used, it may be that the water-gas linkage valve of the water heater is defective, or the internal rubber diaphragm is aging and malfunctioning, and it should be reported to the manufacturer's maintenance station for maintenance.

1. Low gas pressure and large gas consumption during the New Year.

2. The water pressure in the circulating system is low, and it is time to replenish water.

3. Tap water is stopped.

4. Maintain the temperature of the bathing water.

The reason why the gas water heater went off immediately after a while was lit:

The water pressure is not enough. The nozzle is clogged, there is limescale or other.

Solenoid valve failure. This product is better to eliminate the product that is now heated with electricity.

1. It is possible that the water pressure at home is too low and causes the fire to go out. 2. It is also possible that the air pressure at home is too low, or the flame is out caused by a sudden gas stop. 3. If the water heater at home is battery-powered, then there is a possibility that the battery is out of power.

4. It is also possible that the water heater itself is faulty. 5. The failure of the air pressure switch of the water heater will also cause this phenomenon. Suggested Treatment:

1. First of all, you need to check whether you have forgotten to fill the gas at home, the gas at home suddenly stops, there is no combustible, and of course, the water heater will automatically turn off when you let it. 2. If you are a friend who lives in a high-rise building, you will often encounter a sudden decrease in water flow during the peak period of water consumption, that is, the water pressure at home is insufficient, and there is not enough water to flow to the water heater, and the water heater will naturally stop burning in order to prevent dry burning and protect the water heater from being damaged. 3. If you are using a battery-type water heater at home, you must check whether the power is sufficient, pinch the battery with your hand, and find that the battery is soft, which means that the battery is out of power, and you can buy a new pair of batteries to replace it.

4. The water heater also has a service life and years, if it is used for too long, it will cause the internal parts to age, so it will automatically turn off in the process of use, and you need to buy a new water heater.

Check for power supply issues.

Check whether the AC power plug indicator is on, and first rule out the problem of the power supply part.

Solenoid valve failure.

When ignition, only the ignition sound is heard, and there is no solenoid valve "click" magnetic suction sound, which may be due to the damage or aging of the solenoid valve, or it may be that the gas pressure is too high or too low.

It is more likely that the solenoid valve has dirt. The solenoid valve can not be overgas, gas.

Faulty electric igniter.

One of the pulse igniters and the controller is faulty, and neither the water heater can ignite.

It is very difficult to ignite when the ignition needle is offset or aging, and the ignition needle can be replaced or placed correctly; b.Induction aging, you can polish the induction and place it well (so that the flame can fully burn the induction needle regardless of large fire or small fire).

There are several reasons why the gas water heater lighter goes off as soon as it goes off:

1.Gas problems: It may be that the gas** is unstable, causing the lighter to not continue to ignite.

This can be caused by reasons such as the gas valve not opening enough, the gas pressure is insufficient, or the gas pipeline is clogged. Modeling: Check that the gas valve is fully open and make sure that the gas ** is normal.

2.Faulty lighter: The lighter itself may be faulty, preventing it from continuing to ignite. In this case, it is advisable to contact a professional maintenance personnel for service or replacement of the lighter.

3.Gas valve problem: The gas valve may have a problem with the code and cannot control the gas flow normally. This can lead to a fire extinguishing quickly after the lighter is ignited. If you suspect that the valve is faulty, it is recommended to contact a professional maintenance personnel to deal with it.

Please note that gas water heaters involve gas use, and if you are not familiar with the operation or sock troubleshooting, it is highly recommended to consult a professional for inspection and treatment to ensure safety.

Hello dear, how about the gas water heater extinguished as soon as the fire water comes: 1. First of all, look at the water pressure, the water pressure is too small, and the water heater will not work, as long as you turn on the faucet to see if the water is smooth or not, and if it is not smooth, the water pressure is not good. 2. Look at the air pressure, the air pressure is not normal and can not be heated, if it is a cylinder, but also to see if it is a problem with the pressure reducing valve.

3. Consider whether there is a problem with the pulse igniter, its high-voltage circuit can not work normally, and can only form a high voltage for a short time, so it will also ignite for a short time. 4. If it is the kind of battery power supply to close the stool and light the stool, consider whether the battery is out of power, and if there is a problem with these two, only consider replacement. 5. Whether the wind pressure switch is faulty can be corrected by adjusting the "+" screw on its back.

6. Consider the feedback pin and its connecting cable, which can be eliminated by replacing the feedback pin and reconnecting the feedback cable. 7. Finally, there is a problem with the CPU processing unit, which can only change the circuit board.
