LG Washer Won’t Fill Up Correctly or Won’t Stop Filling: How to Fix

LG Washer Won't Fill Up Correctly or Won't Stop Filling: How to Fix

LG washers are considered one of the most reliable and innovative washing machines available on the market. You might think that washers are simple household machines, but they are very complicated with many moving mechanisms. If there is even one small part that malfunctions in the appliance, then your LG washer may not fill up with water or clean your clothes properly.

Fixing your LG washer’s water drainage and temperature issues require verifying that the appliance is installed correctly. Also, check for mechanical failure caused by inlet valves, faulty switches, and debris. Other issues may require the LG washer to be serviced by an authorized technician.

LG Washer Won’t Stop Filling Up With Water

LG Washer Won’t Stop Filling Up With Water

Water enters your LG washer through the water inlet valve. If your washer stops filling up with water or does not get enough water, it could be a water valve issue. Figuring out if the water inlet valve is malfunctioning requires conducting a quick test that you can do yourself. 

Check the Water Inlet Valve

During the filling phase of the wash cycle, shut off the electrical power to your LG washer. If you find that your washer is still filling up with water even after the disconnection from a power source, then the water inlet valve is faulty and needs to be replaced.

Beyond a faulty valve, any issues with the water filling the washer can be due to the season. According to LG, the cold weather conditions can affect the supply lines by freezing the water within the lines. 

The freezing of water can also make the washer fill slower as there may be a buildup of ice particles within the lines that slow the supply of water. When the temperatures become warmer, the water supply will resume and fill the washer at the usual speeds.

Generally, LG front-load and top-load washers do not require much hot water as the appliances are designed to use energy consumption efficiently. However, you may find that your LG washer does not fill up with any hot or cold water or have temperature issues. Any issues with the water temperature also involve checking the water inlet hoses for any defects. 

Check the Water Inlet Hose

If the water inlet hose leading to the washer becomes kinked or bent to a certain degree, this can also hinder water flow and cause the washer to fill slower than intended. You should always check the water inlet hoses behind the LG washer and straighten the hoses out. Also, check to ensure that the hoses are not cracked or leaking water.

Inspect the water inlet hose to ensure that you did not switch hot and cold water lines during the washing machine installation. It can be easy to mix up, but the valve for hot water has a red ring or has a marking with a letter H to stand for “hot.” Afterward, check the hot and cold water lines to the supply valves to ensure both are open so water can flow through the hoses.

If you have not cleaned your inlet filters in your LG washer recently, now is an excellent time to check if there is any debris buildup. This blockage may slow the water flow or block the flow of water entirely.

Check the Inlet Filter

First, turn off all the water taps and remove the hoses from your LG washer. Then, look inside the cold and hot water valves, and remove the filters. Be very careful during this step to avoid damaging any component of the machine. Clean the water inlet filters; you can use a toothbrush to clear away any debris gently. You might need to replace the filter entirely, depending on the severity of the blockage.

In some cases, depending on the washer model, these screen filters are not sold separately from the water valve, so if you damage it, you may need to replace the whole part. Always keep an eye for any damage or cracks in any parts of the washing machine. But once the water inlet filters are clean and installed back into the taps, start or continue a wash cycle to see if the water fills quicker.

LG Washer Keeps Filling and Draining

In the case of your LG washer overfilling during the filling cycle, or it keeps filling and draining, then there may be a case that your air dome tube or pressure switch is malfunctioning. 

Check the Water Level Switch

Your washer measures water level with an air dome tube or an air hose, which compresses the air when there is pressure due to the water level in your tub. When the tub reaches a certain point, the air in the air dome tube pushes against a switch that turns off the water inlet. This mechanism stops water from flowing into the tub.

Depending on the washer model, the pressure switch’s failure means that the water inlet valve will continually fill the appliance with water. Since the pressure switch automatically shuts off the power controlling the water inlet valve if the water reaches the correct level for the cleaning cycle, water can overflow in the washer if the pressure switch is not working correctly. 

Before automatically deciding to replace the pressure switch, you should also check to see if there is any debris around the air tube of the pressure switch and ensure that nothing is leaking. Feel across the air tube’s length or look through the air tube with a flashlight.

Check the Water Pressure

LG washers need proper water flow and water pressure; otherwise, the washer will fill up slowly. The minimum amount of water pressure required for LG washers is approximately 14.5 psi, and the maximum amount of water pressure is 116 psi. Low water pressure can also make the cleaning less effective as detergent may not be entirely rinsed from within the washing machine. 

Additionally, if the water inlet valve does not get the proper amount of pressure, the valve can not close even after being disconnected from an electrical power source. This defect may cause some water to leak into the washing machine, leading the washer to overflow with water.

Call an Expert

LG washers are considered a premium product, which is why LG has a fleet of expert Factory Service technicians all across the United States (and the rest of the world). Check your LG washer for any warranty information and request a technician to service your appliance rather than fixing the device by yourself. 

LG Factory Service technicians are trained for over 200 hours and receive new information on the latest LG products. Depending on the issue’s complexity, it might be best to leave it in an expert’s hands.

Final Thoughts

Your LG washer could have the following problems:

  • Won’t stop filling up with water
  • Keeps filling and draining
  • Has filling issues with the correct water temperature
  • Does not get enough water

These issues may be due to various malfunctioning parts in the appliance, from the water inlet valve to even the pressure switch. Check each part of the washing machine to narrow down which component is defective and cause these water-related issues. But beyond these checks, always consider calling a service technician as the issue may be more complicated than anticipated.
