How to fix a washing machine filling hot water on cold setting

The majority of washing machines have two hot and cold water input valves. Each one connects to a supply pipe in the laundry room’s wall. You can vary the hot and cold water mix in the tub by adjusting the temperate control on the front of the washing machine control panel to clean different types of clothing more effectively. If your machine’s cold water isn’t working, try troubleshooting it before calling a repair service.

If your clothes come out of the washer hot or especially warm, the most likely cause is that they are rinsed in hot water. When the cold valve is accidentally connected to the hot tap, this occurs.

As odd as that may appear, I’ve come across this a surprising number of times. Some individuals have been doing this for years with their washing machines.

Steps to fix the washing machine filling hot water on cold settings

Step 1: Check that the cold water supply is turned on and flowing to the washing machine by turning the right-hand water valve on the wall behind it counterclockwise.

Step 2: Turn on the washer’s cycle control knob, select any cycle, and pull the knob to start the machine.

Step 3: Set the water temperature control to “Cold” only and check the temperature by holding your hand under the water pouring into the washer drum. Whether there is no water in the tub, turn the temperature knob to “Hot” to see if hot water will flow from the wall valve to the appliance. You may have an issue with the cold-water supply line if the drum begins to fill with hot water.

Step 4: Turn the knob on the cold-water valve at the wall clockwise to turn it off.

Step 5 Remove the supply hose from the wall valve by twisting the brass coupler clockwise on the hose’s end with pliers or a wrench. Drain the water by lowering the horse’s back into a pail.

Step 6: Disconnect the power cord from the washer. Using pliers or a wrench, pull the washer away from the wall and disconnect the cold-water supply hose from the back of the appliance.

Step 7: Using a small toothbrush dipped in white vinegar, clean the screen inside the valve. That clears the screen of any dirt or mineral deposits.

Step 8: Place the entire cold-water hose in the sink and connect one end to the faucet.

Step 9: Run water through the hose to check for obstructions and, if required, replace the hose.

Step 10: Reconnect the cold water hose to the washer’s back and the wall supply valve.

Concerns about washer water temperature 

If you’re having trouble regulating the temperature of your water, try the following:

  • Verify that the hot and cold water supply valves are both switched on. Make sure the hose connections aren’t in the wrong order. The letters “H” for HOT and “C” for COLD are written on the hoses.
  • Check to see if the correct temperature setting was chosen: Make sure the water heater in your home is set to 90-120 degrees Fahrenheit. When it reaches the washer, HOT wash water is the house hot water supply. See Washers – Hot Water not working or Not Hot Enough for 2015 and later models.
  • WARM is a mix of hot and cold water that enters the washer and can vary based on the entering water’s temperature. Note: The warm water temperature on newer washers, starting in 1995, is slightly lower than on prior versions. That is because the hot and cold water are mixed differently. That was done to comply with federal energy regulations because the cost of heating the water is the most significant energy expense for a clothes washer, minor modifications in the amount of hot water used to result in energy savings without sacrificing wash quality.
  • Depending on the incoming supply, COLD may range from near freezing in some regions in the winter to around 80 degrees Fahrenheit in the summer. Note that the efficiency of detergent is significantly reduced when the water temperature is shallow (below 60 degrees F, 15.6 degrees C). The incoming water temperature is lower in the winter, and the resulting warm water temperature is also lower.
  • Check for clogs in the water valve screen. If one-half of the water valve fails, the washer will only receive hot or cold water. If either the cold or hot temperature settings do not work, the valve screen may be obstructed. See Washer Slow Fill with Water for instructions on cleaning the water valve screen.

Note: If your model has a temperature sensor, you may automatically hear the water valves turn on and off when the temperature is adjusted.

Connecting washing machine hoses

The connections of hot and cold water that lead to the main plumbing lines in the washing room are made via a pair of hoses used by washing machines. Each end of the hose has a threaded coupler, usually made of brass, which connects to the pipes in the laundry room and the intake pipes on the rear of the washing machine. A couple, which is found at appliance repair stores and gardening centers, must join two washing machine hoses to produce a more extended hose connection.

1) To turn off the water flow to the washing machine, turn the water valve knob on the laundry room wall.

2) Using the pliers, unscrew the brass ring on the hose end from the wall pipe.

3) Tighten the coupler by inserting one end into the hose’s end.

4) Tighten one end of a second hose to the opposite side of the coupler. Connect the second hose’s opposite end to the wall pipe and tighten it.

5) Check for leaks in the connections by slowly turning on the water valve knob at the wall. To stop water from leaking, use pliers to tighten the coupler and hoses.

How to Select the Most Appropriate temperature for the laundry Water

Ensue that follow the Care Labels on Your Clothes

Always make sure you read the care label for each cloth that you wish to wash. You will get the details that will help you get the best water temperature suited to wash the fabric. If you’re new to Laundry or the garment is unique, it’s incredibly crucial to follow the instructions on the label.

  • Dirty Laundry Sorting

Ensure that you separate the clothes after you have double-checked the labels. Separate them based on the color, material, water washing temperature, and also weight. If there are clothes of the same type, you’ll get significantly better outcomes in lint management, filth removal, and color transfer prevention.

  • Choose cold water first

In any case that the cloth label is absent, wash soiled clothes, especially colored ones, and you should wash them in cold water. Coldwater ensures that the fabric does not damage much, such as shrink, fade, and bleeding the cloth color. However, in case the stains removal is not satisfactory, warm water will help.

The rinse cycle water temperature

Using a cold water rinse is a suggestion that that works with all rinse cycles and cloth materials. Coldwater is always used for rinsing the fabric because it is efficient and has no effect on stain removal. When you set the cold water for every load you are rinsing, you will save some cash since you will not need to pay the bills for heating the water.

Frequently asked questions;

Washer water temperature differences

The hot water setting in most clothes washers is 54.4 degrees Celsius or higher. For more information, consult your washer’s handbook and the settings on your household water heater. There will be a rise in temperature during each wash cycle if your washer has a steam cycle.

The warm water temperature is always kept at 43 to 32 degrees Celsius, while the cold is between 15 to 26 degrees Celsius. During the cold seasons, outside conditions can have a significant impact on cold water temperatures. Detergents in powder form do not dissolve easily in cold water below 60°F (15°C). As a result, it will leave some residues on the clothes that may not get thoroughly washed.


We’ve all had trouble with our washing machines. Sometimes when you are on the cold water cycle, and only hot water comes out, or you set your washer so that you can rinse with cold water, but the clothes come out hot. 

When you change the setting again, the same thing happens. That is a problem that you should not worry about anymore since we have discussed it in this article. In case of any complicated damage, consult a professional.
