LG washer keeps filling with water
LG washer keeps filling with water. If the washer continues to fill with water even when it is not getting power, check for a defective water inlet valve. The water inlet valve switches power to the water pump so you can have running water. If the inlet valve is bad, replace it. Also, check the pressure switch, which turns off power to the inlet valve when enough water has filled the tub.
Here we will discuss some solutions for the LG washer keeps filling with water.
Defective Water Level Switch
The washer’s water level switch is a pressure-activated switch that determines when the tub needs to stop filling with water.
The switch has purposes separate from each other. One contact sends power to the water inlet valve, which causes the tub to fill. Once the tub has filled, another contact sends power to the motor, and so on and so forth.
Each leg can be tested individually with a multimeter to determine if it is still able to carry an electric current or not if it doesn’t carry electricity well anymore then you’ll need to replace it.
If it’s no longer providing power to anything then there’s nothing more you need to do.
Water Inlet Valve issue
It is best to turn off your washer power while it’s filling up with water. If the washer keeps filling with water even when it doesn’t have power, that means you have a defective water inlet valve.
When the water inlet valve has something wrong, you should replace it.
Pressure hose attached to the water level switch
There are several possible causes of the problem you’ve described regarding your washer not leveling off properly (filling with water until reaching the appropriate level before stopping the cycle).
One possibility is that the tubing attaching the pressure hose to your water pump has perforations or tears through which air is escaping.
A decrease in air pressure will make your washer think it has more capacity than it does, meaning that water will continue to empty into the tub when it’s already full.
Faulty control board
Lastly, if you have checked and tried all of the above recommendations yet your washer has not stopped overflowing, there may be a fault with the mainboard.
The board allows your washer to run and initiate cycles, monitor functions, and locate faults.
If the board is damaged then it will mean that your washer cannot communicate with other components like the water inlet valve or water level switch, which results in it overflowing.
You can test for damage on the boards by looking for signs of burning or exposed wires that might have been disconnected. To diagnose properly you’ll want to call a trained professional if repairs are needed.
Adjustment of water pressure
While there are many reasons why some machines overflow, most of the time it’s a simple fix that can be done very quickly.
Sometimes all you need is to adjust your washer’s incoming water pressure and other times it may require removing filters or vacuuming out the excess lint from the filter screen.
Other than that, if none of these simple steps work for you, your only option will be to call a plumber.
Low Water Pressure
The water supply to your washer may not be sufficient and could very easily cause the washer’s valve to completely misfire.
To remedy this, you’ll need to check the pressure coming out of your faucets by attaching a hose from one of them to your sink drain.
If you find that pressure isn’t high enough, perhaps have an electrician run a new line for you or talk to an expert about increasing the pressure on what is already in place.
