As an expert in home improvement and renovations, I‘m delighted to provide you with this ultimate guide to help you understand the ins and outs of your washing machine‘s water valve. Whether you‘re trying to locate the valve, turn it on or off, or troubleshoot flow issues, this guide will cover everything you need to know in a clear, friendly format.
Locating the Washing Machine Water Valve
The water valve is the key component that controls water flow into your washing machine. Knowing where it‘s located is the first step to properly using and maintaining it.
On most washers, you‘ll find the water valve on the back of the machine in the lower right or left corner. This puts it nearby the water supply lines that feed into the washer. The valve itself is usually made of brass, plastic or metal and has a rotating handle to turn water on and off.
Here‘s a close-up look at a typical washing machine water valve. As you can see, it has inputs for both hot and cold water lines. The valve handle adjusts flow between hot and cold based on how far you turn it in each direction.
Now that you know where to look, locating the water valve on your washing machine should be quick and easy. Just peek around the lower back corner and look for the valve and supply lines.
Identifying Hot and Cold Valves
Once you‘ve spotted the water valve, it‘s important to know which side is hot and which is cold. The hot water valve is usually on the left while the cold water valve is on the right. However, that standard orientation doesn‘t always apply.
To be certain, check any text or indicators printed directly on the valve. Many valves will have "HOT" and "COLD" stamped on the appropriate sides.
If your valve doesn‘t have clear labels, refer to your owner‘s manual or the manufacturer‘s website for diagrams and instructions. They should clarify the hot and cold sides for your specific model.
As a last resort, you can test the water temperature at each valve:
- Turn on each valve independently while feeling the hose connection. The hot valve will make the hose much warmer.
- Alternatively, use a thermometer to test the exact water temperature from each valve. The hot valve will supply warmer water, likely over 100°F.
Taking a moment to properly identify hot and cold will prevent confusion when you need to adjust or troubleshoot the washing machine‘s water supply.
Is the Water Valve On or Off?
The water valve handle points in different directions depending on whether the valve is open or closed:
- Valve On – Handle is parallel to the water supply lines. Water can flow through the open valve.
- Valve Off – Handle is perpendicular to the lines. The valve is closed and blocks water.
To allow water flow, make sure the valve handles are turned so they align with the supply lines as pictured on the left.
If your machine has separate hot and cold valve handles, check that both handles are properly open before use. Shut off both valves when the washer won‘t be used for an extended time.
How to Turn the Water Valve On and Off
Using the valve is as easy as rotating the handle 90 degrees to align or unalign it with the water lines.
To turn on the valve:
-
Locate the valve handle on the back of the washer.
-
Rotate the handle clockwise approximately 90 degrees.
-
Stop when the handle is parallel to the water supply line.
To turn off the valve:
-
Locate the valve handle.
-
Rotate the handle counter-clockwise 90 degrees.
-
Stop when the handle is perpendicular to the water line.
Most washing machine valves operate with this standard 90 degree rotation. Refer to your owner‘s manual if your model‘s valve mechanism differs.
I recommend turning the valve on and off slowly to avoid water hammer, which can cause pressure spikes and pipe damage.
Now you know how to easily control water flow to your washer using this important valve component!
Checking Water Flow to the Washing Machine
If your washer is not filling properly with water, the water valve is one of the first things to check.
Start by verifying the valve is fully open and the handle aligned to allow water flow. Try running a wash cycle and listen for sounds of the valve opening.
Next, check the water lines and hoses connected to the valve. Make sure there are no kinks, blockages, or leaks that could prevent proper water supply.
You can also test by running water at another faucet in the home that uses the same supply lines as the washing machine. If water flows freely from the faucet but not the washer, then the issue likely lies with the washer‘s specific valve or hoses.
If you‘ve confirmed no plumbing supply issues, the problem may be electrical rather than the actual water valve. Contact an appliance repair technician for assistance diagnosing and servicing the washer.
Emergency Water Shut-Off Valves
In addition to the main water valve, your washing machine likely has emergency shut-off valves built into the supply lines:
These miniature valves allow you to quickly turn off the water in case of a burst inlet hose or other leakage problem. The emergency valves are located higher up on the hot and cold water lines. They operate just like the main valve using a 90 degree rotation to align or unalign the handle with the water line.
It‘s a good idea to familiarize yourself with the location of your washing machine‘s emergency shut-off valves so you can act quickly in the event of a plumbing emergency. Turning off the water at the source helps minimize damage if a rupture or leak does occur.
Preventative Maintenance of Water Valves
To keep your washing machine‘s water valves functioning properly over the long run:
-
Periodically inspect the valves and hoses for wear, cracks, and mineral buildup. Replace deteriorating rubber hoses.
-
Operate the valve handles to ensure they turn smoothly. Replace stiff or grinding valves.
-
Clean out any debris and sediment around valve inlets using vinegar or valve cleaning brushes.
-
Confirm water pressure at the valve is in the safe 40-60 PSI range using a pressure gauge.
-
Shut off water at the valves when leaving home for extended periods.
Well maintained valves will provide years of reliable service. But valves do wear out over time, so periodic inspections and replacements help avoid problems down the road.
Valve Types by Washer Brand
While valves serve the same purpose, their exact location and style varies across washer brands and models. Here are some of the more common valve types and placements:
Whirlpool top-load washers – Water valve is centrally located at the top back with separate hot and cold valves.
GE top-load washers – One dual combination hot/cold valve in lower back right corner.
LG front-load washers – Dual hot and cold valves in lower back or side panel.
Samsung front-load washers – Dual or single valve configurations in lower left or right corner.
Maytag front-load washers – Combination hot/cold valve in lower right or left corner.
Consult your owner‘s manual or manufacturer website for your specific model‘s valve type and location if needed. While valve designs vary, the basic operation remains similar across different washing machine brands and models.
Troubleshooting Water Valve Issues
Here is a quick troubleshooting guide covering common water valve problems:
No or low water flow:
- Check valve is fully open
- Inspect for kinks/clogs in supply lines
- Test inlet water pressure
- Clean inlet screens on valve
Leaking valve:
- Tighten valve connections
- Replace worn washers and seals
- Check for cracks in valve housing
Valve turns hard:
- Lubricate with penetrating oil
- Replace stiff valves
Loud banging noise:
- Fix water hammer with water arrestors
- Ensure valve opens/closes slowly
Washing machine not filling properly:
- Ensure power supply to washer is active
- Test/replace solenoid coils in valve that activate water flow
- Replace faulty control boards or timers
For valves requiring repairs beyond basic maintenance, professional service may be needed.
Key Takeaways:
-
The water valve is located on the lower back corner of most washing machines
-
Identify hot and cold valves based on labels or water temperature
-
Aligning the handle with the water lines means the valve is ON
-
Rotate handle clockwise/counter-clockwise 90 degrees to turn valve ON/OFF
-

-
Maintain valves via cleaning, inspection for wear, and replacing deteriorating hoses/washers
I hope this comprehensive guide has helped explain everything you need to know about your washing machine‘s all-important water valves! Let me know if you have any other questions as you maintain and operate the valves on your washer.
