LG washing machine constantly fills with water

It can be annoying to deal with a washing machine that refuses to stop filling with water. This issue has the potential to result in soggy laundry and a malfunctioning machine.

There may be multiple causes for this problem if your LG washing machine is having it. Gaining an understanding of these causes will enable you to resolve the issue and restore your machine to normal.

This post will explain the typical causes of an LG washing machine overflowing with water and walk you through the troubleshooting and repair procedures.

If the water in your LG washing machine is always filling up, it is probably because of a broken pressure switch or a broken water inlet valve. These parts are in charge of regulating the water flow and determining when there is sufficient water in the drum. Early detection of the problem can help avoid water damage and expensive repairs, so it’s imperative to take quick action.

Manifestation of a breakdown

Two or three times during a cycle, a washing machine in good working order fills and drains water. Both before and after the pre-wash, main wash, and rinse, this procedure takes place. As water is continuously entering the machine’s tank, it is very difficult to ignore the situation. The user is able to see:

• constant noise of water being collected and discharged through the drain system during the washing process;
• increase in the time of the set mode, the cycle is extended due to incorrect execution of the running program by the washing machine;
• poor quality of washing – the laundry remains dirty and soapy. This is explained by the fact that the required concentration of the soap solution cannot be achieved.

A washing machine that is continuously accumulating and draining water should not be operated; the issue needs to be fixed right away.

Installation errors

What should be done if such an issue is found? Prior to anything else, make sure that the washing machine installation has complied with all manufacturer specifications, including connecting to the sewer. In order to prevent water from the tank from spontaneously draining, the drain hose needs to be placed at least 50 centimeters above the floor. After detecting a drop in the liquid level in the drum, the pressure switch signals the main board, which then causes the system to add the necessary amount of water to the tank, starting a vicious cycle.

As a result, make sure that the drain hose was connected correctly by checking for errors first. The location of the hose needs to be above the washing machine tank. In the event that locating the drain hose cannot be done visually, take these actions:

• start any washing program;
• wait until the tank of the automatic machine is completely filled with water;
• turn on the "Drain" option;
• press the pause button after the liquid begins to drain from the tank;
• continuous drainage of water after the equipment has stopped working indicates obvious problems with the hose connection.

If the washing machine truly shuts off while in pause mode and stops draining water, the "insides" of the machine need to be checked for the source of the issue. We’ll advise you on the next thing to check.

Problems with the inlet valve

The inlet valve in LG washing machines can malfunction, preventing the water intake from shutting off. A malfunctioning element will cause liquid to flow into the tank continuously. As a result, the system instructs to fill the drum with water before beginning the wash. When an inlet valve breaks, the water intake cannot be stopped in time, which triggers the protection mechanism and directs excess water into the sewer. In a circle, the procedure will be repeated. The user needs to be aware of how strongly the water is pressurized as it enters the tank.

• slow filling indicates damage to the membrane;
• high water filling speed indicates failure of the valve itself.

It is not possible to fix the inlet valve; instead, a new, functional component needs to be installed in its place.

The steps involved in taking apart the outdated inlet valve and replacing it with a functional one are as follows:

• turn off the power to the washing machine;
• remove the top cover of the case (for front-loading models) or the side cover of vertical-loading washing machines (since the element is located at the bottom);
• find the inlet valve, disconnect the wires and pipes from it;
• depending on the method of fastening the part, unscrew the bolts or loosen the latches that fix the valve;
• carefully remove the element;
• install the serviceable valve in its original place, fix it, connect the wiring and hoses;
• attach the removed wall of the case in place;
• run the wash in test mode.

Choosing a replacement part that is comparable to the one that was removed is crucial. As a result, choose the inlet valve with caution, paying particular attention to the "home assistant" model.

The water level sensor is broken

In the event that the machine overflows with water, a pressure switch malfunction could be the cause. The sensor keeps track of the water level in the tank and notifies the main unit when the supply needs to be turned on or off. The "brain" of the washing machine receives inaccurate information about the amount of liquid in the tank if the water level sensor fails, which results in an equipment malfunction. The pressure switch might malfunction as a result of:

• short circuit or oxidation of its contacts;
• clogging of the pressure pipe or the appearance of cracks, kinks on it;
• break in the tightness of the membrane.

You should first examine the sensor. In the event that oxidation happens, the contacts must be cleaned. You will need to clean the pipe if a blockage is found. To fully swap out the pressure switch for a new one, follow these steps:

• turn off the washing machine from the network;
• remove the top cover of the machine;
• disconnect the tube and wiring from the level sensor;
• disconnect the elements that secure the part to the body: bolts, screws, terminals;
• dismantle the faulty pressure switch, install a new part in its place;
• fasten the sensor with screws, connect the terminals, tube;
• replace the lid of the washing machine.

Replacing the pressure switch on your own, without the assistance of a professional, is simple. Select a replacement water level sensor that precisely matches the model of your washing machine when making your purchase.

It’s critical to take immediate action if your LG washing machine is overflowing with water in order to prevent more damage and higher water costs. Performing basic inspections, such as examining the water inlet valve and verifying correct installation, can frequently address the issue.

But if none of these remedies resolve the problem, it might be time to seek professional advice. Problems that keep coming up could be a sign of a more serious issue that needs professional assistance.

Maintaining your washing machine will save you money and time in the long run by ensuring that it runs efficiently and extending its lifespan.
