Last Updated on: 17th June 2023, 06:56 pm

Washing machines carry out most of the tasks without any human assistance unless you’re using an old model.

The latest washing machines automatically do most tasks, such as water in-taking, rinsing, drying out, and draining — with no human help.

However, knowing that every washing machine doesn’t drain out water automatically is vital. As a result, such washers require human effort to drain the dirty/soapy water out of the washing machine.

Your grandma probably has had a washing machine that doesn’t drain the water automatically. Instead, one needs to spread the drain pipe horizontally to drain the water out of the washing machine.

So probably that’s why you were a tad bit curious about washing machine drainage.

Anyway, let’s discuss how washing machines drain out the water or I should say the methods used for draining the water out of the washer.

Two Ways to Drain the Washing Machines

Here are two ways to drain washing machine water after a wash cycle:

1. Automatically drain the water out of the washer

In fully automatic washing machines, the user doesn’t need to do anything to drain out the water from the washer. As soon as the wash cycle finishes, the washing machine drains out the water automatically, making it possible for the next stage to begin.

Most of the new washing machines have this feature to drain out the water without any human assistance. They are programmed to drain the water once the wash process is completed.

2. Drain the water out of the washer by hand

In comparatively older washing machine models, the users have to drain out the water from the washer by hand.

The way it works is that when the wash cycle completes and the washer gives a buzzer or whistle to hint that the wash process is done, the user is required to drain out the water from the washer.

As a result, the drain pipe needs to be stretched out to let the water drain out of the washing machine. If you forget to lay down the drain pipe after the wash cycle finishes, the washing machine may start giving an error.

You won’t want any leakage or short circuit inside the washing machine, so drain out the water timely.

How High Should the Drain Hose Be for a Washing Machine?

The exact height of a drain hose is difficult to tell as it may vary from washing machine brand to brand. Plus, there is always a difference between the settings of front-loading and top-loading washers. Washer manufacturers are the best source for such information.

However, for most washers it should be at least 24” off the floor. In some cases, it could be 30”. It’s necessary to consult the expert or look at the washer manual for optimal performance.

If the drain hose height doesn’t match the ideal size, chances are, the washing machine would struggle with pumping out the wastewater. As a result, it may start affecting the performance of the washing machine in the long run.

FAQs About Draining Washing Machines

Let’s take a look at some of the frequently asked questions about draining washing machines:

Where should the drain be for a washing machine?

The drain for a washing machine should be located near the washing machine’s lower area and should be connected to a drainpipe that leads to a sewer or septic system. It should not be connected to a sink drain or other non-sanitary plumbing fixture.

What is the washing machine drain called?

The washing machine drain is typically referred to as a standpipe or a drain hose.

Does a washing machine drain need a vent?

Yes, a washing machine drain requires a vent to prevent water from being siphoned out of the trap and to allow proper airflow in the plumbing system. This vent is typically installed through the roof or an exterior wall.

Does a washing machine need a drain pan?

Installing a drain pan under a washing machine is recommended to prevent water damage in case of leaks or overflow. Some building codes may require a drain pan, so it’s important to check with local regulations.

Why does my sink gurgle when my washer drains?

If your sink gurgles when your washing machine drains, it may be due to a partial blockage in the drain line or vent pipe. When the washing machine drains, it creates a surge of water that can push air out of the sink drain, causing the gurgling sound. A plumber can help diagnose and fix the issue.

What happens if the washing machine drain is too low?

If the washing machine drain is too low, it can cause problems with proper drainage, as the water may not flow out of the machine quickly enough. This can lead to backups, clogs, and overflows. It’s essential to ensure that the drain is properly installed at the correct height.

Does the washing machine drain need to be high?

The washing machine drain does not necessarily need to be high, but it should be installed at the correct height to ensure proper drainage. The drain should be higher than the highest water level of the washing machine, but not too high that it creates excessive pressure that can damage the machine’s pump.

Why is my washing machine not draining fully?

A washing machine may not be draining fully for a variety of reasons, such as clogs in the drain hose or pump, a faulty pump, a malfunctioning lid switch, or a kinked hose. It’s important to troubleshoot the issue and address it promptly to prevent further damage to the machine.

Will the washing machine drain if I pour water?

No, pouring water into the washing machine will not cause it to drain. The washing machine is designed to drain automatically when the cycle is complete, and pouring water into it can cause damage to the machine’s internal components. If you are experiencing drainage issues, it’s best to troubleshoot the cause of the problem and address it accordingly.
