How to Fix a Washing Machine That Won’t Drain

A washing machine that won’t drain is one of the most common and frustrating laundry problems — you open the door to find clothes sitting in a drum full of water. Before you call a technician, there are several things you can check and fix yourself. This step-by-step guide walks you through the most common causes.

Why Is My Washing Machine Not Draining?

The most common causes are:

1. Blocked drain filter (most common)
2. Kinked or blocked drain hose
3. Blocked household drain or standpipe
4. Faulty drain pump
5. Electronic or programming fault

Step 1: Check for a Blocked Drain Filter

Most front-load washing machines have a drain filter (also called a pump filter or coin trap) at the bottom front of the machine, usually behind a small door or panel. This filter catches lint, coins, hairpins and debris that would otherwise block the pump. It should be cleaned every 1–3 months.

How to clean it:

1. Place towels on the floor — water will spill when you open the filter.
2. Open the filter door and look for a small drain hose (a black flexible tube). If present, unplug the cap and let the water drain into a tray.
3. Turn the filter cap anti-clockwise to remove it. Some models require a coin or flat-head screwdriver.
4. Remove the filter and clean it thoroughly under running water. Remove all debris.
5. Check the filter housing inside the machine for any remaining debris.
6. Reinsert the filter, turn clockwise until snug, replace the drain hose cap and close the door.
7. Run a drain/spin cycle to test.

Step 2: Check the Drain Hose

The drain hose runs from the back of the machine to your household drain or standpipe. Check for:

• Kinks or bends that restrict water flow. Straighten the hose.
• The hose end inserted too far into the standpipe (more than 15cm causes a siphon effect). Pull it out slightly.
• Blockages in the hose itself. Disconnect and flush with water.

Step 3: Check the Household Drain

Pour a bucket of water slowly into the standpipe or laundry tub. If it drains slowly or backs up, the household drain is blocked — not the machine. Use a drain cleaner or snake, or call a plumber.

Step 4: Check for a Pump Fault

If the filter is clean and the hose is clear but water still won’t drain, the drain pump itself may be faulty. Signs include:

• A humming sound during the drain cycle with no water movement
• Complete silence when the drain cycle should be running

Pump replacement is a repair most competent DIYers can do with guides on YouTube, but it does require pulling the machine away from the wall, disconnecting hoses and accessing the pump. If in doubt, call a technician.

Step 5: Run a Diagnostic or Reset

Some washing machine faults are electronic. Try:

1. Switching the machine completely off at the wall for 5–10 minutes.
2. Restarting and selecting a drain and spin cycle directly.
3. If the machine displays an error code, look it up in the manual.

When to Buy a New Washing Machine

If your machine is 8+ years old and the pump has failed, the cost of parts and labour (typically $200–$400) may approach the cost of a new entry-level machine. It’s worth getting a repair quote and comparing against a replacement.
