There is really no such thing as a little leak, because any leak can create severe water damage and they all have a way of draining your bank account. Knowing how to repair a leaking washing machine drain hose is something you will need to do at some point and the longer you wait to fix it, the worse it's going to be.

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.

Why Water Is Your Enemy

It's a well-known fact of life that plumbing problems are going to cost you money. Plumbers are expensive and if you DIY repairs, mistakes are going to cost you money.

It's tempting to put off seemingly "little" projects like a washer machine drain hose leaking, but you shouldn't. This is a problem that can cause damage, which means this is 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 for people and pets in the house.

Causes of Leaking

Wondering why is my washing machine drain hose 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, just for starters.

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

There are other issues that can cause leaking around the washing machine that may not be coming from the hose. Check these problems to see if perhaps you're having one of these issues, rather than the slightly more complicated problem of a leaking washing machine drain hose.

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 the leaking is not coming from one of these problems, it is likely coming from the hose.

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.

Where is the drain hose on a washing machine?

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 and fully secured to the machine at one end and the drain or wall at the other.

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. You definitely want this used water to be drained away because you only want clean water to wash your clothes with.
