LG Washer Won’t Stop Filling Up With Water

LG Washer Won’t Stop Filling Up With Water

One reason why an LG washer won’t stop filling with water is a faulty water inlet valve. To fix this, shut off the electrical power to your LG washer during the filling phase of the wash cycle. If 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. 

There could be several other possible reasons for why LG washer won’t stop filling with water. Here’s a troubleshooting guide to help you identify and potentially resolve the problem:

  1. Water Inlet Valve Malfunction: The water inlet valve is responsible for controlling the flow of water into the washer. If the valve is stuck open, it can result in continuous water filling. To test this, you can unplug the washer and see if the water flow stops. If it doesn’t, the water inlet valve may need to be replaced.
  2. Water Level Sensor Issue: The water level sensor, also known as the pressure switch, detects the water level in the washer tub. If this sensor fails to communicate with the control board, the washer might not receive the signal to stop filling. A faulty water level sensor might need replacement.
  3. Drain Hose Placement: If the drain hose is positioned too low or too far into the drain pipe, it can create a siphoning effect that prevents the water level sensor from accurately detecting the water level. Ensure that the drain hose is properly placed and not submerged too deeply in the drain pipe.
  4. Control Board or Timer Malfunction: A malfunction in the control board or timer can prevent the washer from receiving the correct signals to stop filling. This might require professional diagnosis and repair or replacement of the faulty component.
  5. Pressure System Blockage: Sometimes, debris or lint can clog the pressure system components, which affects the water level sensor’s functioning. If this is the case, cleaning out the pressure system could solve the issue.
  6. Wiring Issues: Loose or damaged wires connecting the various components of the washer can disrupt communication and cause problems with stopping the filling process.
  7. Faulty Water Level Pressure Switch: The pressure switch might be faulty and not accurately detecting the water level changes. If this is the case, replacing the pressure switch might be necessary.
  8. Software Glitch: In some cases, a software glitch or electronic hiccup can cause the washer to behave unexpectedly. Try unplugging the washer for a few minutes and then plugging it back in to see if this resolves the issue.

It’s important to note that dealing with appliances like washing machines involves electrical components and potential hazards. If you’re not comfortable or experienced with appliance repair, it’s recommended to seek assistance from a qualified technician or LG customer support to diagnose and fix the issue safely.

LG Washer Won’t Fill Up With Hot or Cold Water

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.
