How Do I Clean My Washing Machine Drain?

Before you start, you'll need to move the washing machine away from the wall and find the drain. It's usually a pipe behind the unit, and it attaches to the hose that carries the wastewater away. Make sure that you don't accidentally remove the hot- or cold-water lines. You can usually tell the difference because the drain pipe is generally thicker than the supply lines.

You'll then need to remove the pipe by pulling it or unscrewing it from the machine before you can clean it. It's best to place some old towels under the area where the pipe enters the machine to soak up any standing water.

How to Clean a Washing Machine Drain Using a Drain Snake

Once you've removed the drain pipe, put on some rubber gloves and insert the drain snake, keeping a firm hold of the handle. Push it slowly down the pipe, moving it around gently to feel for blockages. If you feel resistance, twist the handle clockwise to allow the snake to collect any sediment or dirt.

Each time you remove a blockage, pull the snake out of the pipe and pull the clog off the wire. You can then reinsert it and continue removing any blockages from the pipe until you think you've got them all. You can test whether the pipe is clear by pouring water through it.

Ensure that any drain cleaner you use in a washing machine drain is suitable for your pipe material and drain type. It's best to avoid using products containing sulfuric acid due to its potential to damage your plumbing system and negative environmental impact.
