Washer Buzzing Not Draining

Introduction

A washing machine that buzzes but doesn’t drain is a common and frustrating problem for homeowners. This usually means your washer is trying to pump out the water, but something is preventing it from doing so. Leaving water in your washer can lead to mold and mildew growth, and a non-draining washer is unusable. Addressing this issue promptly is important to prevent further damage and costly repairs.

Common Causes of Washer Buzzing Not Draining

Here are some common reasons why your washer might be buzzing but not draining:

Clogged Drain Hose: The drain hose carries water from the washer to the drainpipe. If it’s blocked, water can’t escape.
Blocked Drainpipe: Even if the hose is clear, the drainpipe in your wall could be clogged.
Faulty Drain Pump: The drain pump is responsible for pushing water out. If it’s failing, it might buzz but not pump effectively.
Stuck Object in Pump: Small items like socks, coins, or buttons can get lodged in the drain pump, preventing it from working.
Lid Switch Malfunction: Some washers won’t drain if the lid switch (which detects if the lid is closed) is broken.
Obstructed Filter: Many washers have a filter to catch lint and debris. A clogged filter restricts water flow.
Control Panel Issues: In rare cases, a problem with the washer’s control panel can prevent the drain cycle from initiating.
Kinked or Damaged Drain Hose: A kink in the hose restricts water flow. A damaged hose could leak and reduce pumping efficiency.

Symptoms Checklist

Use this checklist to confirm the issue:

The washing machine is full of water after the wash cycle.
You hear a buzzing or humming sound during the drain cycle, but no water is being pumped out.
The washer’s drain hose is connected, but water isn’t flowing through it.
The washer’s display panel might show an error code related to draining.
The buzzing sound might be accompanied by a burning smell (immediately unplug the washer if this happens).

How to Fix Washer Buzzing Not Draining Step-by-Step Guide

Unplug the Washer: For safety, always disconnect the washer from the power outlet before starting any repairs.
Locate the Drain Hose: This is usually a corrugated hose at the back of the washing machine.
Check the Drain Hose for Kinks: Straighten any kinks or bends in the hose.
Detach the Drain Hose: Carefully detach the drain hose from the drainpipe or standpipe. Have a bucket ready to catch any remaining water.
Inspect the Drain Hose: Look for any visible clogs or obstructions inside the hose.
Flush the Drain Hose: Use a garden hose or sink faucet to flush out any debris from the drain hose.
Check the Drainpipe: Make sure the drainpipe in the wall isn’t clogged. You can use a plumbing snake or a straightened wire hanger to clear any blockages.
Locate the Drain Pump: Consult your washer’s manual to find the drain pump’s location. It’s often located at the bottom front or back of the machine.
Access the Drain Pump: You may need to remove an access panel to reach the drain pump.
Check the Drain Pump Filter: Many washers have a filter near the drain pump. Clean this filter by removing any lint, hair, or debris.
Inspect the Drain Pump Impeller: Check the drain pump impeller (the fan-like part inside the pump) for any obstructions. You might need pliers to carefully remove any stuck objects.
Reassemble and Test: Reattach the drain hose, plug in the washer, and run a short drain cycle to see if the problem is resolved.
Check the Lid Switch: If the problem persists, inspect the lid switch. Make sure it’s clean and that the lid is properly engaging the switch. Try gently pressing the switch while running a drain cycle (be extremely careful).

Fix the Issue Without Buying Parts

Before considering replacement parts, try these free solutions:

Washer Reset: Unplug your washer for 1-2 minutes to reset the control panel. Plug it back in and try running a drain cycle.
Deep Cleaning: Regularly clean your washing machine with a washer cleaner to prevent build-up of soap scum and debris.
Drainage Recalibration (If Applicable): Some high-end washers have a recalibration process for drainage. Consult your manual.
Hose and Connection Inspection: Regularly inspect the hoses and connections for wear and tear to prevent leaks and maintain proper drainage.
Maintenance Basics: Leave the washer door ajar after use to allow it to dry out and prevent mold growth.

When Replacement Might Be Necessary

If the above steps don’t solve the problem, the drain pump itself might be faulty and need replacement. Replacing a drain pump typically costs between $50 and $200, including the part and labor. Other parts that could potentially fail include the lid switch (around $20-$50) or, in rare cases, the control panel (which can be more expensive, ranging from $100-$300+).

Safety Warning

Always unplug the washing machine before performing any repairs.
Be careful when working with water to avoid electric shock.
If you’re uncomfortable with electrical or plumbing work, call a qualified technician.
Keep children and pets away from the work area.
Clean up any spilled water immediately to prevent slips and falls.
