Samsung Washer Knocking

Introduction

A knocking sound coming from your Samsung washing machine can be alarming and indicate a problem that needs attention. This knocking usually happens during the spin cycle, fill cycle, or even during normal washing. Ignoring it can lead to more serious damage to your appliance and potentially cause flooding. This guide provides a step-by-step approach to identify the source of the knocking and resolve it yourself, saving you time and money on potentially expensive repairs.

Common Causes of Samsung Washer Knocking

Here are some of the most frequent culprits behind a knocking Samsung washer:

Unbalanced Load: Clothes clumped together can cause the drum to become unbalanced, leading to knocking.
Washer Not Level: An uneven floor can make the washer rock and knock against the floor or surrounding objects.
Loose Objects: Items like coins, buttons, or small toys caught between the inner and outer drum can create a knocking noise.
Damaged Drum Bearings: Worn-out bearings cause the drum to wobble and produce a loud knocking sound, especially during the spin cycle.
Worn Suspension Rods/Springs: These components stabilize the drum. When worn, the drum can bang against the machine’s frame.
Foreign Object in Drain Pump: Small objects can get lodged in the drain pump, causing it to knock or vibrate loudly.
Loose Drive Pulley: The drive pulley connects the motor to the drum. If it loosens, it can cause knocking during rotation.
Water Hammer: Sudden changes in water pressure can create a knocking sound in the pipes connected to the washer.

Symptoms Checklist

Use this list to help pinpoint the issue:

Knocking only during the spin cycle.
Knocking only when filling with water.
Knocking throughout the entire wash cycle.
Knocking accompanied by vibration.
Knocking sounds louder at higher spin speeds.
Washer rocking or moving excessively during operation.
Visual inspection reveals an uneven load distribution.
Visible damage to the washer’s exterior.

How to Fix Samsung Washer Knocking Step-by-Step Guide

Follow these steps to troubleshoot and fix the knocking issue:

Stop the Washer: Immediately stop the washer if you hear knocking to prevent further damage.
Check for Unbalanced Load: Open the washer and redistribute the clothes evenly around the drum. Avoid overloading.
Level the Washer: Use a level to check if the washer is level. Adjust the leveling feet at the bottom of the machine until it’s stable and even. Tighten the lock nuts on the leveling feet.
Inspect the Drum: Manually rotate the drum. Listen for any unusual noises. If you hear grinding or scraping, it could indicate damaged drum bearings.
Check for Loose Objects: Turn off and unplug the washer. Check the rubber seal around the door and inside the drum for any trapped objects.
Access the Drain Pump Filter: Consult your washer’s manual to locate the drain pump filter access panel (usually at the bottom front). Place a towel and pan to catch any water. Carefully remove the filter and clean out any debris.
Inspect Suspension Rods/Springs (If Comfortable): Unplug the washer and remove the top panel (refer to your manual). Inspect the suspension rods and springs for any signs of damage or wear. They should be intact and provide support to the drum.
Check Water Supply Hoses: Ensure the water supply hoses are securely connected and not kinked. Kinks can restrict water flow and cause knocking.
Run an Empty Cycle: After addressing potential issues, run an empty wash cycle to see if the knocking persists.
Observe and Listen: Pay close attention to when the knocking occurs during the cycle. This can help you further isolate the problem.
Check the Drive Pulley: With the washer unplugged, try to manually rotate the pulley (usually located at the back of the machine). Check if it is loose or wobbly.

Fix the Issue Without Buying Parts

Before considering replacement parts, try these free solutions:

Reset the Washer: Unplug the washer for 5 minutes, then plug it back in. This can sometimes resolve minor electronic glitches.
Clean the Washer: Run a self-cleaning cycle with a washing machine cleaner to remove any buildup or debris.
Recalibrate the Washer: Some Samsung washers have a calibration mode. Consult your manual for instructions.
Regular Inspection: Periodically check the washer for levelness and loose objects.
Proper Loading: Always load the washer with evenly distributed clothes.

When Replacement Might Be Necessary

If the knocking persists after troubleshooting, and you suspect damaged drum bearings or a failing motor, replacement might be the only option. Drum bearing replacement can cost between $200-$400 (USD), while motor replacement can range from $300-$600 (USD). Worn drum bearings and motors are the most common culprits requiring part replacement.

Safety Warning

Always unplug the washer from the power outlet before performing any troubleshooting or repairs.
Be cautious when handling water to avoid electrical shock.
If you are not comfortable performing any of these steps, consult a qualified appliance repair technician.
Wear gloves when handling potentially dirty or contaminated components.
