As a common appliance in life, the ceramic ignition needle is believed to be familiar to consumers. It seems to be a small tool, but it is not very impressive, but it can also play a big role. This product is a ceramic ignition needle. When you hear such a tall name, you know the material used to make it. It must be extraordinary. It is indeed the case. It is made of materials that are resistant to high temperature, not easily deformed, and have a stable structure. Its aluminum metal needle can even maintain its stability at temperatures as high as 1,500 degrees Celsius. It has made a huge contribution in burning part of the gas, diesel oil, lighting the stove, etc. I really didn't expect such a small body to burst into such a powerful force, it really can't be judged by its appearance!

1. The water heater has been used for a long time, and the internal joints are loose. It is recommended to tighten or replace with a new one.

2. If it has been used for more than two years, there may be a problem with the induction needle of the water heater, and the conductive effect is not good.

3. The incinerator is broken. After ignition, the water heater will catch fire due to natural reaction, but it will go out after a few seconds due to insufficient heat induction. It is recommended to replace the incinerator.

4. The solenoid valve is broken.
5. The battery is out of power, it is recommended to replace the battery;
6. Sometimes this phenomenon occurs due to the reverse ventilation of the exhaust pipe (pipeline). It is suggested that installing a hood on the exhaust port can solve the problem.

Ceramic ignition needle water heater maintenance analysis and maintenance: According to the above fault phenomenon, it is judged that the electric heating rod or power board of the water heater is faulty. Disassemble the machine to check that the two electric heating rods inside the water heater are in good condition, and clean up the jelly-like substances. The transformer input AC220V and output ACI IV. AC13V are measured, normal; the voltage regulator block LM7806 outputs 6V voltage, normal, and the regulated output voltages are 5.3 V, 4.6 V, and 3.4 V, respectively, normal; the rectified load relay pulls in 12 V The voltage is also normal.​

The water heater maintenance has been powered on and tested many times and found that when 2 000 W is selected, the two relays at the power input end are turned on, and there is an AC220V voltage output. When 1000 W is selected, the two relays at the power input end of the water heater are not conducting, which is the same as the shutdown state. The above inspection shows that there is a problem with the 1000 W control circuit of the two relays at the power input end. Further comparison and inspection of the control circuit shows that there is a diode open circuit, and the fault is eliminated after replacement.
