How to Repair a Washing Machine That Won’t Drain

A washing machine that won’t drain can disrupt your laundry routine, but many drainage issues can be resolved with some basic troubleshooting and repairs. Before calling a professional, try these steps to diagnose and fix the problem yourself. This guide assumes you have basic tools like a screwdriver, pliers, and a bucket, and are comfortable with minor appliance maintenance. Always prioritize safety by unplugging the machine and turning off the water supply before starting.

Step 1: Check for Simple Blockages

The most common reason for a washing machine not draining is a clog in the drain hose or filter. Start by inspecting the drain hose, typically located at the back of the machine. Ensure it’s not kinked or bent, as this can restrict water flow. Next, detach the hose carefully (place a bucket underneath to catch water) and check for blockages like lint, coins, or small clothing items. Run water through the hose to confirm it’s clear.

Many machines also have a drain filter or pump filter, often accessible via a small panel at the bottom front. Open the panel, remove the filter, and clean out any debris. Rinse the filter thoroughly before reinstalling it. Clearing these blockages resolves the issue in many cases.

Step 2: Inspect the Drain Pump

If the hose and filter are clear, the drain pump might be the culprit. The pump, responsible for pushing water out of the machine, can become clogged or fail entirely. Locate the pump—usually near the bottom of the machine, accessible by removing the back or bottom panel (consult your manual for specifics). Check for debris like hair or fabric stuck in the pump’s impeller. Rotate the impeller manually; it should move freely. If it’s jammed, clear the obstruction.

A humming noise when the machine tries to drain often indicates a pump issue. If the pump is clear but still doesn’t work, it may need replacement. Pumps are relatively inexpensive (typically $30-$100), and replacing one involves disconnecting hoses and wiring, then installing a new unit. Ensure the replacement matches your machine’s model.

Step 3: Examine the Lid Switch

Some washing machines won’t drain if the lid switch is faulty, as the machine assumes the lid is open and halts the cycle for safety. Test the switch by pressing it manually or listening for a click when closing the lid. If it’s defective, the switch can be replaced with a compatible part after disconnecting the old one from the control panel. This repair is straightforward but requires care to avoid damaging wiring.

Step 4: Check the Belt (For Belt-Driven Models)

In older or belt-driven machines, a worn or broken belt can prevent the pump from operating. Inspect the belt by accessing the machine’s underside or rear panel. Look for signs of fraying or snapping. If damaged, replace it with a belt specific to your model, ensuring proper tension during installation.

Step 5: Test the Control Board

If all else fails, the issue might lie with the machine’s control board, which manages the drain cycle. Diagnosing this requires technical expertise, so consider professional help if you suspect a board malfunction. Resetting the machine by unplugging it for 10 minutes can sometimes resolve minor electronic glitches.

When to Call a Professional

While many drainage issues are fixable at home, persistent problems or complex repairs—like control board replacements—may require a technician. If you’re uncomfortable with any step or lack the tools, it’s wise to seek expert assistance to avoid further damage.

Preventive Tips

To prevent future drainage issues, clean the filter monthly, avoid overloading the machine, and use the correct amount of detergent to minimize lint buildup. Regular maintenance keeps your washing machine running smoothly.

By following these steps, you can often restore your washing machine’s drainage function without costly repairs. Patience and careful inspection are key to getting your laundry routine back on track.
