Water leaks create the opportunity for water damage, which can cost you as a homeowner. If one of the problems in your home is a washing machine leaking from a drain hose, this is easily repaired or replaced. It is also a project that should be done as soon as you notice the leak.

Standing water from a leak can lead to mold, attract mosquitos, and become a safety hazard.

You may need to get some help to remove the washing machine drain hose from its position, but once this is managed, you should be able to do the rest of the project by yourself.

Causes of Leaking

There are many potential causes of washing machine hose leaking. The problem could be from drain pipe damage, a door not closing properly, a blocked drain, a leaking detergent drawer, a tear in the cuff, drain filter leaks, and a leak in the washing machine itself.

With a water drain hose, leaks occur when the connection between it and the machine and the wall is disconnected. Your machine vibrates while in use which can over time cause the hose to loosen.

If the drain is clogged, you'll need to clean it out. Again, put a bucket under the area to collect water. Make sure to disconnect it in order to remove all gunk that has gathered inside the trap and then reconnect it.

If your washing machine door is not closing properly, you will notice water pooling around your washing machine. Check to make sure there isn't something stuck near the door itself, like a loose button. If this is the issue, simply remove it and close the door.

If your detergent drawer is leaking, some debris or leftover detergent has likely gathered in the area. Simply clean it out and the machine should stop leaking.

If there's a tear in the cuff, you will need to contact the maker of your washing machine to get the piece replaced.

A clog in your drain hose can also cause leaking. One way to do so if the drain hose is clogged is by pouring water into it to see if it has been backing up. Another way is to blow air through it, which again will indicate if the hose has been clogged and is backing up as a result.

If the drain hose is clogged, you can usually clear it with a plumbing auger. Use it the way you would on any other clog. If you do not have one on hand, you may be able to borrow one from a friend or neighbor. Some home improvement stores will also allow you to rent the device for a day or even a half-day rather than purchasing one, as they can be quite a costly investment.

Using the plumbing auger won't take very long, so renting it for a day or even a half-day will suffice. If you do not know how to use the device, have whoever you are renting it from do a quick demonstration for you on the correct technique to use with the device.

Location of the Drain Hose

Before you start the washer drain hose repair, it is important to know where the drain hose is. The washing machine drain hose is usually on the back of the washer. There should also be two additional hoses along the back of the machine: one hose is for hot water and one is for cold water. All of those hoses are incredibly important components of your washing machine and all need to be working properly.

The hot water hose is generally red while the cold water hose is usually blue. These hoses bring clean water into your machine to wash your clothes with. The drain hose, meanwhile, carries dirty water that was used in the cleaning process out of the machine. Think about it—nobody wants dirty water used to wash their clothes, it would completely defeat the purpose of washing them in the first place. That dirty water has to go somewhere, hence the drain hose.

How to Stop a Washer Drain Hose from Leaking

Step 1 - Remove the Hose from the Machine

Before you begin the repair, take care to make sure that the water and electricity supply lines are turned off at the mains in your home before you start the project.

It can also be a good idea to seal off the switches with tape while you are working on the washing machine so that no one else in your home accidentally turns them on while you are doing the project.

Make sure to alert your co-inhabitants as well not to tamper with either until you have completed your project. Now it is time to grab your wrench and remove the bolt which holds the hose to the machine.

Step 2 - Remove the Hose from the Drain

You will have to take the hose off of the drain. You will need an assistant to hold the top of the hose while you go below the drain and unscrew it from the bottom. You should be able to remove it carefully, with one hand free so that you can catch the washers in case they fall through the hole. They're incredibly hard to get to if they fall, so rather than figuring out how to get them out, just make sure you don't drop them in the first place.

The most common place for a leak is at the connector so make sure it is properly threaded. You can add plumber’s tape if needed when you reattach it to ensure a secure fit.

Once the hose is off, take the washers and replace them with new ones. They only cost a few cents each, so even if they are not the cause of the leak, it is worth replacing them while the hose is free. The new washers will also have an extended shelf life compared with the ones that have been on your washing machine for a longer time period already.

Step 3 - Test and Seal the Drain Hose

Once that is completed, you will have to test the hose for leaks. Take a bowl of soapy water, and push the hose through it in segments. At each point, squeeze the hose so that air is forced along with it, and then check for signs of bubbles forming on the hose.

If you find any leaks, then you can fix them using tape, or by using hot glue to form a seal. This will only create a temporary fix for the hose, though, which is probably worn out along its full length and ready to wear through which will create more leaks. You should instead replace the hose with a brand new one, which you can purchase online.

Step 4 - Install the New Drain Hose

Before you finish the project you will have to replace the drain hose on the drain. You may need whoever assisted you earlier to help you hold the hose over the washers and the drain hole while you screw it in from below but it is possible to do this alone.

Once this has been done, you can add the hose to the washing machine. It is now time to turn on the power and water supply lines back on and then check that the hose is no longer leaking. If it's no longer leaking, you are done and can enjoy the use of your washing machine once again.

Can You Patch a Washing Machine Hose?

If you notice a hole in your washing machine drain hose, you may be wondering if you can simply patch it up rather than purchase a new one. While it's possible, most experts recommend repairing it only as a temporary measure. Instead, you should replace the washing machine drain hose with a new machine drain hose. The machine drain hose can be purchased online. Make sure you get the correct one for your specific machine's make and model.

Washing Machine Hose Repair Kits

Washing machine drain hose repair kits are an easy way to get started on your repairs. They can be purchased at home improvement stores or online and don't generally cost very much.

Since most of the supplies you will need to fix the washing machine drain hose, however, are tools that the average person will have on hand, you likely do not need to purchase a washing machine hose repair kit and can instead gather all the materials needed from your tool shed or garage, or even a neighbor in a pinch.

Conclusion

Having a washing machine inside your home is very desirable and much better than having to go to a laundromat every time you want to clean your clothes. Like any other appliance, though, it is important to keep your washing machine in good shape. Make sure you perform regular maintenance and fix any issues as they arise rather than waiting for the machine to stop working entirely.

Many washing machine issues are easy for anyone from a DIY novice to a DIY aficionado to fix themselves. Make sure, however, that you read the owner's manual for your specific device. If your washing machine is still under warranty, do not do anything that may void the warranty. Read the warranty carefully to understand what could potentially void the warranty on your machine.
