Malfunctioning Pressure Switch

Cause

The pressure switch, also known as the water level switch, is an essential component of your LG washing machine.

It’s responsible for determining when the tub is filled to the correct level and for shutting off the water supply accordingly.

When this switch malfunctions, your washer might fill with water even when it’s not in use. This problem typically arises due to wear and tear or an internal fault in the switch mechanism.

The pressure switch is a crucial part of the washing machine, controlling the water levels inside.

A malfunction can lead to the constant filling of water. Typical causes are wear and tear or internal faults.

Solution

The straightforward solution to a malfunctioning pressure switch is to replace it. First, ensure that the issue isn’t due to a blocked or kinked pressure hose.

If the hose seems fine, you’ll need to remove the old switch and install a new one in its place.

While you can handle this task yourself if you’re comfortable with DIY projects, it’s generally recommended to hire a professional to ensure correct installation and avoid potential damage to other parts of your machine.

The best solution for a malfunctioning pressure switch is its replacement. Always check if the issue isn’t caused by a blocked hose before proceeding.

It’s advisable to hire a professional for this task to prevent possible damage to the machine.

Damaged Fill Hose

Cause

A damaged fill hose could be a potential reason why your LG washing machine fills with water when not in use.

The fill hose is a crucial component that directs the flow of water into your washer.

Over time, these hoses may develop cracks or holes, leading to a leak that could appear as if the washer is filling with water on its own.

Solution

To solve this issue, inspect the fill hoses for any signs of wear or damage.

If a damaged hose is found, it will need to be replaced. It’s recommended to use high-quality, durable hoses to prevent future leaks.

Further, check the hose connections to ensure they are secure and not contributing to the problem. Regular maintenance and inspection of your washer’s fill hoses can prevent unexpected leaks and keep your machine running efficiently.

Overused Detergent Drawer

Cause

The overuse of the detergent drawer can lead to an accumulation of detergent residues which might clog the system.

This can result in unwanted water filling in the machine even when it’s not in use. The water inlet valve, which is supposed to stop the water flow, may not close properly due to the detergent build-up.

Solution

The best solution to this problem is to regularly clean the detergent drawer and ensure that no residues are left behind.

If the situation persists after cleaning, consider replacing the water inlet valve as it may have been damaged by long-term detergent exposure.

Remember, regular maintenance and thorough cleaning of the detergent drawer can prevent unwanted water filling.

Don’t overlook this simple yet essential routine. If the issue persists, seek professional help to replace the damaged parts.

Compromised External Tub

Cause

The external tub of an LG washing machine could be compromised due to wear and tear over time or due to physical damage.

A cracked or damaged tub might not hold water correctly, leading to leakage even when the machine is not in use.

This unintentional filling of the machine can be a major sign that your external tub is indeed compromised.

Solution

The most effective solution to this problem is to replace the damaged tub. It’s crucial to purchase a replacement tub that is specifically designed for your LG washing machine model.

Enlist the help of a professional to ensure that the replacement is properly installed to avoid further issues.
