Striker water heater malfunction A9 and flameout

1. When the induced current of the flame detection (feedback electrode) is weak, it is judged that the burner has no fire, resulting in the interruption of the program.

Solution: Adjust the height of the feedback electrode.

2. The combined electrode fails to discharge.

Solution: Repair the combination electrode.

3. The ignition pulse spark is normal and does not ignite.

Solution: Repair the ignition pulse.

Overheat protection. The reason is that the surface of the temperature measurement probe is seriously scaled and the temperature measurement response is sluggish. The phenomenon before the failure is that the actual water temperature is significantly higher than the set temperature to the point where it feels hot, and then suddenly turns off.

The temperature of the heat exchange surface of the water heater is very high, and there will be scale when the water flows over, and after a long time, there will be a lot of scale attached to the inner surface of the heat exchanger, which will accumulate over time, resulting in the blockage of the hot water pipeline, which will cause the hot water output to become smaller (the phenomenon of small water pressure) and the hot water output time will become longer. At the same time, the hot water outlet is equipped with a temperature sensor, which is the narrowest place in the water heater waterway, which is easy to accumulate scale, resulting in temperature sensing lag, resulting in hot and cold water outlets, and serious hot water overheating, causing overheating protection to go out.

It is recommended to clean and descale first, buy a set of gas water heater online without removing the scaler, use it to inject descaling agent into the water heater to clean the inside of the water heater can be solved, the operation is simple and convenient, use it to clean it regularly in the future, when this problem can be avoided again. A lot of people have used it, and it really works.

Wrong circuit connection: Make sure the circuit is connected correctly and there are no loose or disconnected places. 4.

Spark plug failure: Check if the spark plug is damaged or detached and needs to be replaced or reinstalled. 5.

Exhaust system problems: Exhaust system failure to work properly will lead to a backlog of flue gas, which will affect ignition. The air ducts need to be cleaned and the exhaust air cleared.

If you are unable to solve the above problems, please contact a professional repair personnel for assistance. At the same time, pay attention to safety, please follow the correct operation procedures and safety regulations of Zen when using the water heater.

Blind problem with power shed. Solution: Check whether the AC power plug indicator is on, and first rule out the problem of the power supply part.

2. Reason 2: solenoid valve failure. Workaround:

If the ignition is only heard when the ignition is heard, there is no solenoid valve "click" magnetic suction sound, it may be that the solenoid valve is damaged or aging, the solenoid valve is aging, it will be uncontrollable, it can be sucked at the beginning of the ignition, and the fire can be hit, but then it is closed and extinguished; It may also be that the gas pressure is too high or too low, and the output pressure of the cylinder pressure reducing valve will be too high or too low in the water heater using cylinder gas. It is more likely that the solenoid valve has dirt. The solenoid valve cannot be overgased, and the gas (natural gas, liquefied petroleum gas, artificial gas) cannot come out, and it cannot come out, so that the ignition cannot catch fire. Before confirming the quality of the solenoid valve, it is necessary to confirm whether the ignition control circuit is normal, if there is a fault, the solenoid valve cannot be controlled.

3. Reason 3: Electric igniter failure. Workaround:

One of the pulse igniters and the controller is faulty, and neither the water heater can ignite. 4. Reason 4: The main controller is faulty.

Solution: If the motherboard is faulty, you need to contact the after-sales maintenance personnel for timely repair or replacement. 5. Reason 5:

Thermistor bad solution: Replace the thermistor with a new one.

Hello dear, there are multiple reasons for the fault code A9 of the forward water heater; One of the reasons: power supply problems. Workaround:

Check whether the AC power plug indicator is too bright, and first rule out the problem of the power supply part. Reason 2: Solenoid valve failure.

Solution: If only the ignition sound is heard when ignition, and there is no solenoid valve "click" magnetic absorption sound, it may be that the solenoid valve is damaged or aging, and the solenoid valve is aging and disturbed, and it will be uncontrollable. It may also be that the gas pressure is too high or too low, and the water heater using cylinder gas will have the output pressure of the cylinder decompression valve too high or too low, and the water heater cannot be ignited; It is more likely that the solenoid valve has dirt. Reason 3:

Faulty electric igniter. Solution: One of the pulse igniters and the controller is faulty, and neither water heater can ignite.
