Causes Of Loud Noise When Draining
Understanding the causes of loud noise during your washing machine’s draining cycle helps fix the problem quickly. Different parts can create noise if they are blocked, worn out, or loose. Identifying the exact cause saves time and prevents further damage.
Blocked Pump Impeller
The pump impeller pushes water out during draining. Dirt, lint, or small objects can block it. A blocked impeller makes loud grinding or rattling sounds. Cleaning the impeller often stops the noise.
Worn Out Drain Pump
Over time, the drain pump can wear out. A worn pump may hum, buzz, or make grinding noises when draining. It struggles to move water properly. Replacing the pump usually solves the noise issue.
Foreign Objects In Drain
Small items like coins, buttons, or hairpins sometimes get trapped in the drain. These objects hit the pump or drum during draining, causing loud noises. Removing foreign objects stops the rattling sounds.
Loose Or Damaged Hoses
Hoses carry water from the machine to the drain. If they are loose or damaged, water flow creates unusual noises. Tightening or replacing hoses can reduce or remove the noise during draining.
Motor Or Belt Issues
The motor and belt work together to spin and drain water. A worn belt or motor problem causes squeaking or banging sounds. Checking these parts and replacing worn components quiets the machine.

Signs Of A Faulty Drain Pump
A faulty drain pump often causes loud noises during the draining cycle. Identifying signs early helps prevent further damage. Watch for unusual symptoms that indicate pump problems. These signs show the drain pump may need repair or replacement.
Water Left In Drum
Water remaining in the drum after a cycle shows poor drainage. The pump may be blocked or broken. Clothes stay wet and heavy. This sign points to a drain pump failure.
Unusual Grinding Or Buzzing Sounds
Grinding or buzzing sounds during draining mean the pump struggles to work. Objects stuck inside the pump can cause this noise. The motor may be wearing out or jammed.
Clicking Noises During Drain
Clicking noises suggest the pump tries to start but cannot. The impeller may be stuck or damaged. Electrical issues inside the pump could also cause clicking.
Burning Smell
A burning smell from the washing machine warns of an electrical problem. The drain pump motor might be overheating. This smell requires immediate attention to avoid fire risks.
Water Leaks Near Pump
Leaks near the drain pump area indicate seals or hoses are damaged. Water escaping can harm other parts of the washer. Leaks often accompany pump failure signs.
Testing The Drain Pump
Testing the drain pump is a key step to find why your washing machine makes loud noise when draining. The drain pump moves water out of the washer. Problems in the pump cause noise and drainage issues. Testing it helps confirm if the pump is faulty or blocked. Follow these steps to check the drain pump safely and accurately.
Safety Precautions Before Testing
Unplug the washing machine from the power outlet. This stops any risk of electric shock. Wear gloves to protect your hands. Work in a dry area to avoid slips. Keep children and pets away from the workspace. Ensure the washing machine drum is empty of water. Use tools carefully and follow instructions step-by-step.
Accessing The Drain Pump
Locate the drain pump at the bottom or back of the washing machine. Remove the access panel or back cover using a screwdriver. Keep screws in a safe place to avoid loss. Disconnect the wires connected to the pump gently. Take out the pump carefully to avoid damage to pipes or wires. Check the pump housing for visible damage or blockages.
Using A Multimeter For Resistance Check
Set your multimeter to the resistance or ohms setting. Touch the probes to the pump’s electrical terminals. A good pump usually shows a resistance between 10 and 100 ohms. No reading or infinite resistance means the pump is broken. A very low reading may show a short circuit inside the pump. Take note of the readings to compare with the manufacturer’s specs.
Interpreting Test Results
Normal resistance means the pump motor windings are okay. No resistance or very high resistance means a motor fault. Low resistance suggests internal short circuits. If results are out of normal range, replace the drain pump. Even if resistance is okay, check for mechanical problems. Testing helps decide if you repair or replace the pump.
Checking The Impeller Manually
Look inside the pump for the impeller, a small fan-like part. Turn the impeller by hand to see if it moves freely. Stuck or jammed impellers cause noise and poor drainage. Clear any debris or lint blocking the impeller. Damaged impellers should be replaced with the pump. This manual check finds physical problems the multimeter cannot detect.
Quick Fixes For Drain Noise
Drain noise in a washing machine can be annoying and signal a problem. Quick fixes often solve the issue without calling a technician. These simple steps help reduce or stop the loud noise during draining. Most fixes require only basic tools and a little time.
Removing Blockages
Blockages in the drain hose or pump cause loud noises. Check the hose for kinks or clogs. Remove any trapped debris or lint. Clear the pump filter if accessible. This allows water to flow freely and stops noise from strain.
Tightening Loose Connections
Loose parts inside the machine cause rattling sounds. Inspect the hose clamps and pump connections. Use a screwdriver or pliers to tighten screws and clamps. Secure fittings reduce vibration and noise during draining.
Replacing Damaged Hoses
Old or cracked hoses leak or vibrate loudly. Look for splits, holes, or worn spots. Replace damaged hoses with new ones of the same size. A fresh hose ensures proper water flow and cuts down on noise.
Cleaning The Pump And Drain Area
Dirt and debris build-up inside the pump creates grinding sounds. Unplug the machine and remove the pump cover. Clean the impeller and pump housing carefully. Regular cleaning keeps the pump running smoothly and quietly.
Resetting The Machine
Sometimes, the washing machine’s electronics cause strange noises. Turn off the machine and unplug it for a few minutes. Plug it back in and restart the cycle. Resetting can clear errors and stop unusual drain noises.
When To Call A Professional
Knowing when to call a professional for a washing machine making loud noise during draining can save time and money. Some problems need expert skills and tools. Trying to fix complex issues alone may cause more damage. Understanding key signs helps decide when to seek professional help.
Persistent Noise After Fixes
If you cleaned the pump and removed debris but noise continues, call a professional. Persistent sounds may mean hidden damage or worn parts. Experts can diagnose and fix problems safely and quickly.
Electrical Component Failures
Noise linked to electrical issues needs a technician. Faulty wiring or control boards cause unusual sounds. Professionals handle electrical repairs to avoid risks and ensure proper function.
