How To Repair LG Washing Machine?

LG washing machine is one of the most popular brands on the market with their latest models and innovations. Including washing machines; LG has a long history of producing home appliances. LG is known for its washing machines which are dependable and simple to use. However, like all machines, LG washing machines can sometimes malfunction too. If you have an LG washing machine experiencing some issues, don’t panic! In this article, we will be discussing how to repair LG washing machine. Here’s how you can repair it yourself. As long as you follow the steps outlined in this article, you’ll be able to repair your LG machine in no time.

What are the Common issues with LG Washing Machines?

The most frequent problems with LG washers include:

  • Excess water from a broken water inlet valve
  • Cables breakage
  • Improper draining

When you are aware of these problems in advance, you can easily repair your LG washing machine more quickly when they arise.

How to fix the LG Washing Machine Draining problem?

If your LG washing machine is not draining properly. The first step is to check the water level and ensure it is filled to the correct level. If the water level is correct, but the machine still does not seem to be draining properly, you may need to replace the clog in the drain line. 

How to replace the clog?

Follow the following steps to change the clog of your washing machine:

  1. Remove the bottom of the washer tub and locate the drain line.
  2. Use a plunger or snake to clear any obstructions from the drain line, and insert a plumber’s snake into the drain line until it reaches the main sewer line.
  3. Turn on your water supply and wait five minutes for the washer to fill with water before replacing your washer tub bottom.

Faulty drain pump

A common issue with LG washers is that they refuse to drain due to a faulty drain pump. After 4-6 years, the drain pump usually fails. If the drain pump fails, you will most likely notice that it is noisier than usual. The washer must be tested with a multimeter (a continuous electrical path) to determine whether the drain pump is faulty.

Foreign objects or items of clothing that pass through the washer’s filters and clog the pump can also cause drain pumps to become clogged. The impellers of the drain pump may also become damaged, causing the pump to stop working correctly.

The type of washer and model number will determine how to access the drain pump. With front-load washers, the drain pump is often accessible by either removing the washer’s front panel or the rear access panel. When using a top-loading washer, the drain pump is often accessed by lying the washer on its back and reaching below. To find out how to reach the drain pump on your washer, consult the handbook and read how to repair an LG washing machine.

How to inspect the drain pump?

The following method will let you inspect your washer drain pump:

  1. Remove the washer’s electrical connection.
  2. Please turn off the washer’s water supply before using it.
  3. The effective access panel should be removed.
  4. It is necessary to unplug the drain pump wire connector.
  5. To unclamp the drain hose clamps to the pump, use pliers. Cut the drain hose off.
  6. Use a 5/16-inch socket to remove the mounting screws for the drain pump.
  7. Remove the pump.
  8. Check the pump for damage or clogs.
  9. Check the pump’s continuity with a multimeter. The drain pump needs to be replaced if there is no continuity.

How to fix overfilling or leaking in the washer?

The water inlet valve in LG washers might also develop defects from time to time. Regular wear and tear or calcium buildup might cause the valve to become flawed. Calcium buildup can cause the valve to get stuck, leading to water leakage from the washer or water buildup in the tub. If you see extra water, mainly if the washer hasn’t been used, there might be a problem with the water entrance valve.

Similarly, the water inlet valve solenoids can fail over time, resulting in excess water and water leakage. The water inlet valve can be visually inspected for damage and continuity tested with a multimeter. If the water inlet valve is faulty, it should be replaced rather than repaired.

The type and model number of the washer will determine access to the water inlet valve. The inlet valve on front-loading washers is usually accessible by removing the washer’s top. Once the screws at the back of the washer have been removed, the top can be lifted off. Top-loading washers require the removal of the control panel and the lifting of the washer cabinet. There are two possible errors:

  1. The water inlet valve can get stuck open.
  2. The washer’s inlet valve is leaking water.

Why does the water inlet valve get stuck open in the LG washing machines?

Due to calcium buildup in the solenoid valve, LG washing machines will begin overfilling with water, and the valve may get stuck open. This problem can occur even when the washing machine is turned off. Therefore, if there is clear water in the drum the next day after laundry, there is a problem with the inlet valve.

Why does the inlet valve leak?

Another common problem with an LG washing machine is leaking water inlet valves. This water could come from the hot or cold inlet valve.

Water supply lines are constantly under pressure; when water solenoids wear out and cannot maintain pressure, you will notice water leaking from them. Before checking the water inlet valve, ensure the hot and cold supply hoses are securely fastened. If they are loose, tighten them to see if the problem is resolved.

How to examine the water inlet valve?

Perform the following steps to check the issue with the water inlet valve:

  1. Turn off the washer’s electricity.
  2. Cut off the washer’s water supply.
  3. The washer’s water hoses should be disconnected.
  4. The effective access panel should be removed.
  5. Take a picture of the connection of the water inlet valve to make reassembly of the washer easier. 
  6. The old inlet valve’s solenoid cables must be disconnected.
  7. The clamps on the four hoses connected to the water inlet valve can be released with pliers.
  8. The water inlet valve must be removed from the washer by removing the mounting screws holding it in place.
  9. Check the water entrance valve for damage and debris that could impede the screens inside.
  10. Using a multimeter, check the water inlet valve for continuity. A healthy water inlet valve should have a resistance between 500 and 1,500 ohms.
  11. Replace a faulty water inlet valve. Most washer repair technicians recommend replacing the water inlet valve rather than attempting to repair it.

How to fix the motor wire harness or sensor wire?

Another frequent issue with LG washers is that the wires in the motor wire harness break due to the machine’s vibrations. Typically, the problem results in the washer making strange noises during the spin cycle.

Similarly, LG washers occasionally experience wire breaks at the position sensor. The control board receives precise motor position information from the position sensor.

A damaged or broken wire can interfere with communication between the control board and the motor in the position sensor wire and the motor wire harness, which may prevent the washer from operating as it should.

The washer’s motor will need to be accessed to inspect the motor wire harness and position the sensor wire. The wire harness or the specific wire will need to be replaced if there are any cracked or burned wires.

The type of washer and the model number will determine how easy it is to reach the motor and position sensor, just like with the drain pump. With front loaders, one front or rear access panel must be taken off. When using a top-loading washer, the motor and position sensor can be accessible by turning the washer on its back and reaching below. The location of the motor or position sensor for your particular LG washer can be found in the washer’s handbook.

Inspection procedure

  1. To inspect the motor wire harness and position sensor, do the following:
  2. Turn off the power to the washer.
  3. Disconnect the washer’s water supply.
  4. To find the motor wire harness, remove the relevant access panels.
  5. Unthread the rotor assembly mounting nut and remove the rotor assembly.
  6. Remove the stator mounting bolts with a socket.
  7. Look for burnt or broken wires in the motor wire harness and position sensor.
  8. Finally, replace the damaged wire harness or individual wires.
