Washing Machine Not Draining? Here Is How to Fix It

Common Reasons Why Your Washing Machine Won’t Drain

- The washing machine’s drainpipe might be clogged. It is common for items such as lint, detergent residue, and even small debris to block this pipe.

- The machine may have a clogged drain filter, which is often located behind a front panel. Sometimes, this filter becomes clogged with debris and may block the flow of water.

- There may be water pump issues due to debris, such as coins and lint, which obstruct the pump’s function and result in a washing machine draining problem.

- The machine may have internal issues like hose blockages. It is common for hoses beneath the drum to get twisted or obstructed, which may lead to improper machine functioning.

- The machine may have control or sensor issues. Models with smart sensors, such as the LG 8 kg 5 Star Inverter Front Loader, may require a reset to re-initiate drainage.

Signs of a Drainage Problem in Your Machine

• Water remains in the drum after the cycle.

• The spin cycle runs, but water does not drain.

• The washing machine gets stuck in the drain cycle.

• Error codes, such as “drain error” or “E21”, may appear.

Unusual noises during draining or spinning indicate a struggle with water flow.

Step-By-Step Guide to Fix a Non-Draining Washing Machine

1. Preparation and Safety

- Unplug the machine before anything else.

2. Clean The Drain Filter

- Locate the filter, which is usually behind a small front panel. You can check the manufacturer’s guide or manual for your specific model.

- Open it gently. Be careful, as some water will pour out.

- Rinse the filter under warm running water and remove all debris.

- Reinstall it securely, then run a quick spin cycle to check the drainage.

3. Clear The Drain Hose

- Detach the hose from the washer and drain the standpipe.

- Look for lint, small items, or residue inside.

- Flush the hose with clear water, then reattach it, ensuring it is free from the floor and has a slight upward slope.

4. Check The Water Pump

- Remove the rear or base panel to access and check the water pump.

- Look for debris around the impeller and remove anything you find.

- Spin the impeller by hand. A smooth motion means it is unblocked.

- Reassemble and run a drain or spin cycle to test.

5. Inspect Internal Hoses

- If you are confident, open the casing of the machine.

- Check hoses for bends or blockages. Clear or replace any obstructive lines.

- Reassemble and test again.

6. Reset or Run the Drain/Spin Mode

- Use the washer’s “Drain/Spin” option to drain water manually.

If your control panel supports it, unplugging the machine for a couple of minutes may reset its sensors and fix the issue.

Preventive Tips to Avoid Future Drain Problems

1. Clean The Drain Filter Monthly

The drain filter’s job is to catch lint, coins, small articles, and debris before they clog your machine’s pump. Over time, these particles accumulate and can block the flow of water. To avoid this:

• Do a monthly filter check; simply open the panel, pull out the filter, rinse it under warm water, and remove any buildup.

• A clean filter ensures water passes freely and keeps the pump from working harder than it needs to.

2. Use Mesh Laundry Bags for Small Items

Loose socks, lingerie, or small fabrics can escape and clog the drain filter or pump. Coins, hairpins, or small items in pockets can also create blockages or even damage internal components. To prevent this:

• Wash delicate or small items inside mesh laundry bags.

• Mesh bags prolong the life of your washer by keeping foreign objects out of key parts.

3. Run a Monthly Maintenance Wash

Detergents, softeners, and fabric dyes can leave behind residues that build up over time in hoses, filters, and drum seals. These residues contribute to blockages and foul odors. To prevent this:

• Run an empty hot-water wash (60–90°C) once a month using a washer cleaner or a scoop of baking soda.

• This deep cleanse flushes soap scum, lint, and buildup from internal parts.

• Most washing machines have a Drum Maintenance Cycle that you can run too.

4. Keep The Drain Hose Straight and Elevated

Kinks or excess bends in the drain hose can disrupt water flow, and a hose lying on the ground may allow wastewater to flow back into the system or strain the pump. To fix this:

• Ensure the hose runs in a smooth, straight line to the drain point.

• The bottom end of the hose should be raised 2–3 inches above the floor or drain trap. This prevents siphoning and ensures gravity assists drainage.

5. Stick to Recommended Detergent Amounts

Using too much detergent may seem like it ensures cleaner clothes, but it can produce excess foam and leave sticky residues in your machine's drainage system. Use High-Efficiency (HE) detergents for HE washers, as they are formulated to rinse thoroughly.

If your machine's water is not draining, simple washing machine maintenance tips often fix the issue. Clear the clogged drain filter, ensure the drainpipe is clear, and check your water pump and internal hoses. If still stuck, a qualified technician can help. With a little care, your washer will continue to deliver clean laundry and hassle-free cycles.
