Causes of LG washing machine errors and how to fix them
The appearance of errors in the LG washing machine leads to a breakdown or the inability to use the equipment. If you find an error, you need to take action to eliminate it.
OE
The appearance of an OE error on the screen means that the water has not been drained from the tank.On mowers without a display, an error is signaled by the simultaneous activation of all the rinsing indicators.
Lack of emptying
In different models of "Lji" brand machines, the water drain time is 5-8 minutes. Whatever the reason for the emptying not being carried out, an error indicator appears.
Reason for appearance
Faced with a problem, you need to find the specific reason why water does not flow from the tank. Further actions are planned depending on the identified cause.
Clogged drain system components
Due to the constant use of the washer, dirt and various foreign bodies accumulate in the units of the drain structure. Debris ends up in the drum with the clothes.
Clogged sewer
Water drained from the tank enters the drain, which can become clogged over time. The presence of a blockage prevents the free passage of fluid from the machine.
Breakage of the water level sensor
If the internal sensor is broken, it does not correctly measure the amount of water. Due to a malfunction of the sensor, the liquid is not drained from the tank and an operating error occurs.
Drain pump malfunction
The water is pumped out by the integrated drain pump. Damage or clogging of the pump prevents it from performing its intended function.
Electrical controller failure
With power surges, failure of the control board often occurs. Also, the machine's electronic controller may fail after prolonged use.
What to do
The action to be taken to restore proper operation of the mower depends on the cause of the error. For a complete solution to the problem, you can use all available actions.
Restart the car
To restart the machine, you need to unplug it from the mains for 10-20 minutes and then turn it on again.A reboot resolves a number of crashes.
Checking the drain filter
The filter periodically accumulates dirt and needs to be cleaned. If you find an error with the water drain, you need to check the condition of the drain filter.
Drain Hose Inspection
Bending or mechanical damage to the drain hose is a common problem among LG owners. In case of folding, you can fix the problem yourself, and if the integrity is violated, you will have to replace it.
The junction of the drain with the main sewer
If the drain is directed to the sink trap, check the connection of the drain hose to the drain. Often, a blockage in the bend of the siphon creates an obstacle to the passage of the liquid.
Pump
After the error appears, check that the pump filter is not clogged. To do this, you need to remove the filter cap, which is located under the hatch cover in the lower part of the case.
Checking the sensors
It is quite difficult to independently check the water level and temperature sensors. To diagnose the error, contact the service center for assistance.
EU and EU
The occurrence of UE errors is associated with the uneven distribution of the drum load along the axis of rotation. The uE code is related to load imbalance where the machine tries to solve the problem on its own.
An UE error is displayed when action is required.
Drum imbalance
Due to an imbalance in the drum, the machine hums loudly and shakes during the spin cycle. In older LG models, the imbalance leads to strong vibrations and modern cars stop working if the balance cannot be restored.
Causes
Most often, the appearance of uE and UE errors is associated with improper use of the machine. To reduce the risk of breakage, you must read the instructions carefully and follow the preventive measures.
Incorrect loading
One of the causes of the error is overloading or uneven distribution of objects inside the drum. Also, a breakdown can mean that too large items are loaded, because of which the drum scrolls strongly.
balance of things
This reason is relevant when washing bed linen, when small things are hammered into the duvet cover. As a result, a large laundry ball forms and the balance is disturbed.
Fault in the control unit
Internal issues are also common in LG-branded machines. Due to malfunctions, vibration increases and the spin function is disabled.
What to do
Once uE and UE errors have occurred, a number of diagnostic steps must be taken. In some cases, it is possible to eliminate failures on your own.
Load and balance control
If the washing machine does not start or does not work properly, it is worth stopping the program, opening the drum and removing unnecessary items or evenly distributing them.
Checking Motor and Controller Drive
If there are system tests in the machine, you can run self-diagnostics. Otherwise, to check the motor and controller, you should:
- remove the back cover;
- disconnect the wires from the motor;
- unscrew the bolts and remove the motor.
For diagnostics, connect the leads of the stator and rotor windings. Then the winding is connected to a voltage of 220 V.
If the rotor turns, the motor and controller are in good working order.
EA
An AE error on the machine screen indicates a failure when trying to auto power off. An unexpected shutdown may occur due to a problem.
Auto power off
The presence of the automatic shutdown function saves the resources of the washing machine. If there is no action for a few minutes after the power is started, the machine will shut down.
float sensor
The probable cause of the AE error is the presence of liquid in the sump. In this case, a leak occurs and the float sensor is triggered.
Checking knots for leaks
If you find a malfunction, you need to check the drain hose assemblies. Leaks are often caused by sharp objects hitting the inside of the drum.
EF
The appearance of an FE error is accompanied by a constant supply and drainage of water. Often an error is displayed when drawing water, but it can also occur when washing or rinsing.
Overflow error
Reservoir overflow is a common cause of error. The AE indicator appears when the fluid level is above the maximum allowable mark.
Checking the integrity of the contacts on the water sensor
A special sensor is responsible for monitoring the water level. Violation of contact integrity results in incorrect measurement.
filling valve
A faulty fill valve causes water to leak when closed. As a result of a failure, an overflow occurs.
Controller
Each LG machine is equipped with a controller that performs the function of controlling the internal mechanisms. If the controller fails, the automatic shutdown may not work.
Lather in the wash
Excessive foam buildup can cause the AE to fail.Foam is caused by using low-quality powder, overloading and washing objects with a porous structure.
E1
Failure E1 appears when there is a malfunction in the fluid filling system. The presence of a defect prevents the washing from being carried out.
Water leak
The average time for filling the tank with water is 4-5 minutes. If during this period the water does not reach the required level, there is a high probability of leakage.
Causes
The reasons for failure often lie in the breakdown of internal mechanisms. Basically, the error is related to the drain system and the leak sensor.
Depressurization of filling and drainage system elements
Depressurization occurs due to damage to the elements. In this case, it is necessary to replace or restore integrity.
Leak adjustment sensor
Lack of control over leaks leads to disruption of draining and refilling water. A broken sensor must be repaired or replaced.
THAT'S TO SAY
The IE indicator means a failure of the water filling system. The code appears if the water has not reached the required level.
There is no water supply
The cause of the breakdown is a malfunction of the water level sensor or the inlet valve. Also, a failure occurs when there is no liquid in the tank at all.
What to do
To restore machine performance, a number of steps must be taken. It is important to correctly identify and eliminate the cause of the breakdown.
Pressure control
First, you need to check if there is water pressure. It can be disabled or blocked.
Supply valve status
The supply valve is blocking the flow of liquid into the washer. It must be fully opened for washing.
Checking the fill valve and pressure switch
The inlet valve is responsible for the water supply. The pressure switch controls the amount of liquid supplied. Both items must be in good working order.
PE
A PE fault can appear during washing, spinning or rinsing. In the future, failure happens constantly.
Water sensor problem
The presence of the PE code means a malfunction of the pressure switch. Due to a malfunction, the sensor cannot detect the amount of water in the tank.
Checking the water pressure in the water supply
A lack of pressure or too much pressure often leads to errors. If you find a breakdown, you need to check the pressure level.
Pressure switch performance
In most cases, the cause of the error is a breakdown of the pressure switch. If the pressure switch tube is clogged, it is enough to blow it out, and in other situations, replacement is necessary.
THE
The LE code appears on the screen after filling with water and trying to spin the drum. Failure is typical for direct drive machines.
Machine door lock error
An error means that the hatch is blocked. The reasons may lie in a loose closure or internal failures.
drive motor
The motor is directly connected to the washer door. Motor failure is a common cause of LE error.
electronic controller
The failure of the electronic controller can be solved by restarting. It is enough to disconnect the washing machine from the network and turn it on again after 10-15 minutes.
of
In the event of a dE error, the machine stops washing. When the power is turned back on, the machine door is not locked.
Problems in the operation of the hatch door
If the washing machine issues the code dE, you need to check the status of the door. The failure is caused by a loose closure.
close the hatch
In most cases, it is enough to close the hatch. Then it remains to start the washing program.
Castle service facility
The door may not close due to a broken lock. Check if the tab fits into the lock.
Checking the control panel, electronic card
The error may be caused by a failure of the control module or the electronic board. A reboot must be performed to resolve the failure.
YOU
When a TE error occurs, the machine suddenly stops. The problem is related to the heating of the incoming water.
Water heater problem
The LG washer may experience a heater circuit failure. This prevents the water from heating up and the washing stops.
Temperature sensor control
One of the causes of the problem is a broken temperature sensor. A replacement is required to fix the problem.
Electronic controller diagnostics
In most cases, the electronic module must be repaired. Diagnostics are required to verify functionality.
PF
The PF code signifies a power failure. Most often, the error is due to a problem with the power supply in the apartment.
Electrical failure
Outages are caused by power surges or outages. If the error is one-time, you can continue to operate freely.
Power cable
It is important to check the condition of the power cord and plug. They are probably damaged and need to be replaced.
Contact connections between control unit and line noise filter
Disconnecting the contacts reduces overvoltage protection. You should always check the correctness of the connection.
LCD panel board connectors on central control board
Damage to the board connector will cause the PF to fail. The defective connector must be replaced.
SE
SE failure means motor failure. The motor shaft does not rotate and the machine does not rotate the drum.
EE and E3
EE and E3 errors can occur during the first boot. The reason for this is the impossibility of determining the load.
loading error
Restarting fixes the boot error. You can also restart your car.
Control block
In rare cases, a breakdown occurs due to a malfunction of the control unit. Diagnostics are needed to check the unit.
CL
The Cl indicator is not an error. The code means child lock mode is on.
Child protection
CL indicates that all buttons are locked except power on. The mode prevents accidental button presses.
How to remove
You can disable the protection yourself. To remove, simply press and hold the button with the lock
