How to fix FE error in LG washing machine

FE error in LG CMSome errors of the self-diagnosis system appear on the display more often, others less often. The FE error in the LG washing machine appears rather rarely, but if it does, it creates a serious problem for the user. How to decrypt this code, how to find and eliminate the cause of its appearance, and is it possible to do it all yourself? In three words, these questions cannot be answered; publication is needed.

Code requires decryption

Depending on the reasons for appearing, the FE code on the display of the LG washer can be displayed both at the very beginning of the program execution, during water intake, and in the middle, just before rinsing. An attentive user will almost immediately be able to link the water intake process and the appearance of the FE error code on the display, but what this means is not clear.

The fact is that the LG washing machine for washing and rinsing is gaining a strictly defined portion of water. Controls the process of dialing a water level sensor. If for some reason the machine draws too much water, having exceeded all permissible limits, an FE error is triggered. Three modules are responsible for the correct water intake in the LG washing machine:

  • water level sensor - it just measures the amount of water that needs to be drawn according to a given program;
  • filling valve - it opens when you need to pour water into the tank of the LG machine and closes when there is enough water;
  • the control module is the electronic brain of the machine, its task is to control the process of water intake by manipulating the water level sensor and the filling valve.

In the event that any of the above modules does not work correctly, the machine may throw an FE error. What are our actions?

  1. We can first try to correctly reset the FE error, suddenly the whole thing is not a malfunction, but a short-term system failure.
  2. If the reset fails, we will need to test all the indicated modules one by one until we find a malfunction.
  3. As soon as the malfunction is detected, we will need to quickly and competently fix it.

Error reset

Suppose that the FE error appears on the display of your LG washing machine for the first time. Disconnect the machine from the button on the control panel, and then completely de-energize it by disconnecting it from the power supply. Then we proceed as follows.draining water from SM LG

  1. We tilt the machine a little back and substitute it under the right leg of the bars so that the machine remains at an angle.
  2. We open the door of the drain filter, after which we substitute a capacious flat container for water, such as a basin.
  3. To the left of the trash filter is an emergency water drain hose. Open the cork and gradually drain the water from the tank.
  4. While draining the water, UBL unlocks the hatch door. Open the door and remove wet laundry from the drum into a pre-prepared clean basin.
  5. Unscrew the drain filter, clean it, and then screw it back.
  6. Remove the powder receptacle, rinse it well with powder residue, and then return it to its place.

Now you can plug the machine back into the mains. As usual, load the powder into the tray, then put the laundry in the drum. Do not overload the machine with linen, but do not put too few things. Download should be normal. If you wash voluminous things, do not put them lumpy, try to straighten the laundry inside the drum as best as possible. That's all, you can close the door and start the washing program again. If the FE error reappears, you should begin a comprehensive check of the LG washing machine.

Note! If you notice a lot of foam inside when wet laundry was removed from the drum, you should clean it or wait until it settles. In rare cases, it is the increased foaming that causes a short-term malfunction in the control module of the LG washing machine.

Checking and replacing the water level sensor

Further actions will depend on the time reserves that you have.If you don’t have time to look for a breakdown, then feel free to contact the washing machine repair master, if you have time, you can try to find and fix the breakdown yourself. Where to begin? We recommend starting with checking the pressure switch. The fact is that the water level sensor is one of the most fragile parts in any modern washing machine. In half the cases, the tube clogs up in this part, and it stops working correctly. In another case, his coil or power wiring is on, and he completely fails. What to do?

  1. First you need to completely turn off the washing machine. Do not neglect safety measures, your life can depend on it.
  2. Next you needremove the top cover of the washing machine LG.
  3. Right above, not far from the right front corner of the case, we can find the desired part.
    location of the pressostat
  4. Unscrew the screw that secures the pressure switch to the machine body, disconnect the tube and chip with wires.
  5. We take a multimeter, set it up and check in turn each supply wiring for a breakdown.
  6. We call the coil of the pressure switch.
  7. If the sensor is serviceable, carefully clean and blow through its tube. We do the same with the hose that wears on this tube.
  8. Put the pressure switch in place.

Keep in mind that even the smallest particles of dirt that get into the tubing of the pressure switch of the washing machine can cause problems, so clean the tub in good conscience.

Checking and replacing the filling valve

location of the filling valve LGDo not rush to put in place the top cover of the LG washing machine, because the next in line is our filling valve, it also needs to be carefully checked. The filling valve is screwed to the back of the LG washing machine. It is connected to the inlet hose, so anyone can detect it without much difficulty.

Do not rush to disconnect the nozzles of the bulk valve, first check the wires and the coil. Testing the wires and coil with a multimeter. If a malfunction is detected, replace the filling valve. If there are no problems with the electrician, it is worth checking the flow filter.

The flow filter is located on the machine body in the place where the inlet hose is screwed. This is a small plastic net, which has the property of clogging with a suspension, which falls on it along with tap water. Clean the flow filter and replace it.

Control module test

Well, we checked the pressure switch and the filling valve, and these parts turned out to be completely serviceable. What's next, and then we have the control module in line. Check and repair such an important and expensive part, we would not recommend you. In order not to aggravate the problem and not get into big money, you should turn to a good master.

Now we are not engaged in advertising service centers, we just want to give you good advice. If you have not dealt with electronics before, do not tackle such a difficult matter. The wizard will test the firmware, reset it and, if necessary, replace some semiconductor elements of the control board. In the event that the control module is badly damaged, it will need to be replaced, which is about $ 70, plus the work of the wizard. Take a word, in such a situation the best solution is the help of a professional!
