What is the reason for the FA failure of Haier washing machine?

Haier automatic washing machine FA fault analysis:

Cause of failure: Haier washing machine fault display FA, is the water level sensor abnormal.

Troubleshooting:

1. The filter under the wave wheel of the laundry bucket is blocked, and the cover next to the wave wheel that drains outside can be removed and cleaned up with a tool.

2. The connection between the water level sensor and the socket on the computer board is not good, so it is recommended to adjust and re-plug it.

3. The plug of the water level sensor is not in good contact with the water level sensor, so it is recommended to adjust and re-plug it.

4. If the detection circuit of the computer board fails, it is recommended to repair or replace the computer board.

5. If the internal fault of the water level sensor is faulty, it is recommended to replace the water level sensor. It is advisable to contact the after-sales department.

How to deal with the failure of the water level sensor of Haier washing machine.

1. The water level sensor is closed with an iron round shell and fixed on the sensor seat with the edge pressing, and the cone needs to be used when replacing.

Unscrew the screws on the back baffle of the washing machine, remove the baffle, and you can see the water level switch of the washing machine;

2. Unplug the line and water pipe of the washing machine water level switch, and the water level switch can be removed;

3. Insert the line and water pipe into the new water level switch;

4. Finally, use a screwdriver.

Just install the washing machine cover back on.

Haier washing machine common faults** maintenance:

1. Fault **e5

Cause of failure: E5 is a water level sensor failure.

Here's how to fix it:

1. Select the hot and cold water inlet program, and the cold water for 30 seconds is advanced when washing the water inlet, and then the hot water is fed, so as to ensure the washing machine.

The temperature of the water in the bucket does not exceed 50 degrees.

2. It is best not to choose the hot water program, so that only hot water when washing may cause the water temperature in the cylinder to exceed 50 degrees, causing damage to the machine.

Second, other faults**:

1. F1: Poor contact with the water level sensor of the washing machine.

2. E1: The washing machine drains out of time, check whether the drain pipe is blocked.

3. E2: The upper cover of the washing machine is not properly covered.

4. E3: The washing machine is unbalanced in dehydration, shake the clothes back and spin them again.

5. E4: The washing machine is overtimed, check the water pressure, and whether the water inlet valve is dirty and blocked.

Fault **fa:

Wave wheel: The water level sensor is abnormal, and the water level sensor is loose. Old**e6

GAIA: The water level sensor is abnormal, the frequency value of the water level sensor has been detected during the whole program, if the signal frequency value of the water level sensor is detected for 8s in a row is not within the range of 30KHZ50KHz, it will be alarmed. Old **err10

Drum: The water level sensor is abnormal, the wiring of the water level sensor is loose, and there is no signal feedback. Old **err10

Duplex drum: the water level sensor is abnormal, the frequency value of the water level sensor has been detected during the whole procedure, if the signal frequency value of the water level sensor is detected for 8s in a row is not within the range of 30kHz50kHz, the alarm will be given. Old**err10 This answer works with any Haier washing machine.

Extended information: 1. Unplug the lower end of the transparent pipe of the water level sensor and blow the air, you can hear the action sound of the sensor, indicating that the water pipe is not leaking.

2. Disassemble the upper part of the washing machine case, unplug the water level selection knob, find the sensor and remove it, blow again and measure the contact contact, find that the contact is poor, and conclude that it is the sensor fault and not the problem of the control board.

3. The sensor is closed with an iron circular shell and is fixed on the sensor seat with a crimping edge, and the water level control knob controls the water level by controlling the distance of the contact with a toothed fork of different depths, so it has to be slowly pried open and removed with a thin change cone.

4. The contact quick-action copper sheet is the same as the ordinary micro switch, but it is larger, and its contact is only a pressure welded copper wire, which is polished with sandpaper and measured to be in good contact and restored to its original state. If the action is not sensitive when blowing, you can adjust the adjusting screw slightly to make it flexible and open.

5. Note that when removing the contact part, you should first remove the side shell (the plate is 2 fixed feet, unplugged), and then remove the water level control iron pressure plate, spring and pressure cap (one pressure plate and one transmission rod), and then rotate the transmission rod core 90 degrees to decompose. Don't throw away those springs and caps.

6. Restore the original state and test the machine.

PG FA fault is the failure of the water level sensor, it has the following possibilities, the first is the poor connection between the sensor and the computer board, the second is the failure of the water level sensor itself, the third may be the failure of the computer board can not detect the signal of the water level sensor, and the fourth may be the blockage of the drain pipe.

The service life of the original car battery is 3 to 4 years, and the life of the ordinary car battery is generally 2-3 years. The service life of the battery is related to the configuration of the vehicle and electrical equipment, such as navigation, multi-screen information display, remote control anti-theft, and the function is used more, because the battery continues to consume power when the vehicle is turned off, resulting in a long-term discharge of the battery, which is harmful to the battery, and the warranty period of the battery is 1 year; Usually pay attention not to lose power, which will prolong the life of the battery.

Battery maintenance. The battery is most afraid of low temperatures, and in a low temperature environment, the battery capacitance is much lower than that at room temperature. Therefore, we should check and maintain it in time, and pay attention to it in daily life:

1. Avoid parking the car in the open-air parking lot for a long time, if it is parked for a long time, the battery must be removed and taken away to prevent the battery from being damaged by icing.

2. The car engine is not easy to start in winter, and the time to start the car each time should not exceed 5 seconds, and the interval between starting again should not be less than 15 seconds. In the case that the ignition is still not ignited after multiple starts, the cause should be found from other aspects such as the circuit, ignition coil or oil circuit. Avoid multiple uninterrupted starts, which can cause the battery to burn out due to over-discharge.

3. The car battery should be charged frequently, and the battery will slowly discharge itself until it is scrapped after not being used for a long time, so the car should be started every once in a while to charge the battery.

4. Clean the binding post of the battery every once in a while, and apply special grease to protect the wiring harness. Always check the accessories and connections on the battery.

5. It is forbidden to use automotive electrical appliances after the car is turned off, and the engine will cause damage to the engine if it does not generate electricity.

It depends on what time period this ** appears, plug-in will appear** is the problem of the motherboard, if it appears before the water ingress ** is the problem of the water inlet solenoid valve.
