Electronic components for the development of electronic information science and technology how to promote the role of how to promote the role of electronic components for the development of electronic information science and technology? As long as we understand the role of electronic components and its usefulness, then for the development of information science and technology is a great potential.

Any development of electronic information science and technology can not be separated from electronic components.

Automatic wave washing machine in addition to the E series of fault codes, there are F series of fault codes. Some of these fault codes are basically the same as the E-series codes. But some fault codes represent different parts of the fault. Let's move on to the reasons why the codes are generated and the solutions. Like the E-Series codes, we're starting from scratch.

Code F0, like E0, is also a power jump failure alarm fault. We can refer to the previous chapter for the solution and detection steps for the Easy Zero failure code.

Code F1, the appearance of this code and E1 is not the same, it represents the part of the fault is communication failure. We focus on checking and the motherboard has a communication fault parts, need a part by part to check. But this is more troublesome to detect. We can also do it this way.

Look at the time the code is displayed, such as a power on the fault code is displayed. The code is likely to be on the motherboard itself. Because as soon as the power is turned on, the motherboard will self-test, and the motherboard is faulty, self-test is not successful, it will display the fault code. We just need to replace the motherboard or repair the motherboard.

For example, if the fault code appears before the water inlet, then this fault is likely to appear between the water inlet solenoid valve and the motherboard. We can go one by one to detect which one of the motherboard and water intake solenoid valve is faulty. After finding the fault point, for the repair or replacement can be.

And then there is a fault code before dehydration. Then this fault part may be in the motherboard and traction motor. We can also detect these two fault parts, find the fault point, for repair or replacement can be. Specific steps can refer to the previous chapter.

Code F2, the code represents the fault of the memory chip EEPROM read and write errors. That is to say, the chip reads and writes the data in the memory is there is an error, or read out, or read the error. The fault part may be the chip, may also be the memory. Memory area if the maintenance of experienced teachers, should be able to replace the individual. At present, we do not have special equipment, only use manual, the chip this fault area we have no way to repair, only to replace the motherboard.

Code F3, the fault represented by this fault code is Hall sensor alarm. Hall sensor in the position of the washing machine motor, basically and the washing machine motor fit together. And the Hall sensor alarm indicates that the Hall sensor itself is faulty or the motor is running abnormally.

The hall sensor is, to put it bluntly, a small piece of the computerized version. He is in the washing machine motor operation at all times in monitoring the motor running normal or not, if the motor running abnormal, he will directly alarm, and then let the washing machine stop working to display the fault code. The overall structure of the Hall element is composed of a small piece of computer board and a magnet. By the voltage input to this small piece of computer plate, and then by the computer plate small magnet output induced voltage by the magnet feedback to the Hall element signal, so as to achieve the purpose of the normal operation of the Hall element.

The problem of Hall element is very common in washing machines and household appliances as well as general-purpose equipment. We can replace the hall element with one of the same type, and then test the washing machine to see if it is running normally. In this case, it is basically the hall element that is the problem. Because the motor itself is very unlikely to have problems.

We can also directly test the motor resistance is normal, that is, to measure the motor coil ends whether there is resistance or on and off. Thus determine whether the motor is good or has been damaged. Then for the problem parts to be replaced or repaired.

Code F4, this code represents the washing machine motor error alarm or computer version of the zero detection error. That means it could be a problem with the motor or the computer board, but at the same time it could be a problem with the power supply at home.

The first thing we need to do is to measure whether the power supply voltage at home is stable or whether it is high or low. If there is such a phenomenon, we just need to install a voltage regulator to solve the problem.

If there is no problem with the power supply voltage at home, then there may be a problem with the motherboard, the motherboard's over-zero detection line is out of order, you only need to replace the motherboard can be solved.

Motor error alarms are generally motor or motherboard problems. We can directly detect whether the motherboard phase motor to deliver normal voltage. If the motherboard has a delivery voltage, it means that the motherboard is not a problem, we can directly test the motor resistance value is normal. Whether the motor has a broken circuit or grounding phenomenon. Find the problem of the fault point directly repair or replacement can be.

Code F5, the appearance of this fault code is on behalf of the washing machine motherboard problems, or temperature sensor problems. Represented by the IBM temperature overheating alarm. In this case, we can only replace the motherboard, because this fault is generally too long to use the washing machine, or the washing machine's motherboard aging caused.

Or maybe the temperature sensor of the high-end washing machine with heating function detects that the water temperature is too high and alarms. That is, this washer has a heating function. There could be a problem with the motherboard or a problem with the water temperature sensor. Find the fault point of the problem, for repair or replacement can be solved.

Code F6, this code is indicated by the IBM excessive current alarm. He represents the motherboard problem, the chip on the motherboard has been aging or the chip itself has quality problems. The only thing you can do is to replace the motherboard.

Code F7, this code represents the temperature sensor alarm. This means that washing machines with this code are equipped with a heating function, which has a temperature sensor and a heating rod.

The problem lies in the water temperature sensor and the motherboard. The first thing we need to do is to check if the motherboard is delivering 5V to the water temperature sensor. If there is voltage that the motherboard is not a problem, it is the sensor's problem, we will directly replace a sensor can be. If there is no voltage, it means that the motherboard is the problem. Directly replace the motherboard.

Code F8, the washing machine appeared this code on behalf of the water level sensor failure. But it does not exclude the problem of the motherboard. We first detect whether the motherboard to the water level sensor voltage, if the motherboard voltage output, that the motherboard is not a problem, if there is no voltage output means that the problem is the motherboard. We just need to repair or replace the parts for the problem.

Today's fault code is introduced here. Later will continue to update. If there is a need for codes for other appliances, you can also look through my previous works. If it helps you, remember to like the attention oh.
