Washing Machine Repair: Spotting Faulty Motors Before They Fail

Washing Machine Repair: Spotting Faulty Motors Before They Fail

Introduction

When a washing machine stops mid-cycle or makes unusual noises, the motor is often to blame. Since the motor powers the drum, even a small fault can lead to bigger and more expensive repairs. Learning how to spot a faulty washing machine motor before it fails can save you money, extend your appliance’s life, and prevent unexpected laundry emergencies. This guide will help you identify early warning signs, understand causes, and decide when to repair or replace.

Why the Motor Matters in Washing Machines

The motor is the heart of your washing machine. It spins the drum, controls agitation, and regulates speed. Without it, the washer cannot perform even basic functions.

• A faulty motor is one of the top three reasons for washing machine breakdowns (Consumer Reports, 2024).
• Repairing a motor can cost $150–$400, while replacing the entire unit may cost over $700.

Common Signs of a Faulty Washing Machine Motor

1. Strange Noises During Operation

If your washing machine makes loud humming, buzzing, or grinding sounds, the motor bearings may be wearing out.

Tip: Differentiate between motor noise and pump noise. The motor usually makes louder and more consistent grinding sounds.

2. Drum Not Spinning or Agitating

If the drum does not spin, even when the cycle continues, this is a classic sign of a failing motor. Broken belts or wiring issues may also contribute, but the motor is often the culprit.

3. Burning Smell or Overheating

A burning smell during wash cycles may indicate overheating or worn-out motor windings. This is a red flag that needs immediate attention.

4. Motor Stops Mid-Cycle

Sometimes, the machine starts but stops suddenly before completing the cycle. This usually happens if the motor overheats and trips the thermal fuse.

5. Excessive Vibrations

If your washing machine vibrates heavily and the drum feels unstable, it may not only be a balancing problem. A worn motor or loose motor mounts could also cause it.

Step-by-Step Guide to Checking a Washing Machine Motor

Step 1: Unplug the Machine

Always disconnect the washing machine before inspecting or testing the motor for safety.

Step 2: Check Visible Wiring

Look for burnt wires, loose connections, or corroded terminals near the motor.

Step 3: Inspect Motor Brushes

Carbon brushes wear out over time. If they look too short or worn, replacement may solve the issue.

Step 4: Test the Motor with a Multimeter

Use a multimeter to check resistance. An infinite or zero reading indicates a faulty motor coil.

Step 5: Listen During Operation

After reconnecting, listen for grinding, humming, or rattling. Persistent noises usually confirm a bad motor.

Pros and Cons of Repairing vs Replacing the Motor

Pros of Repairing

• Cheaper than replacing the entire machine.
• Extends the life of your washer.
• Suitable for newer models under 5 years old.

Cons of Repairing

• Older machines may develop other issues soon.
• Replacement parts may be hard to find.
• High labor costs can sometimes outweigh benefits.

Practical Tips to Prevent Motor Failure

• Avoid overloading: Heavy loads strain the motor. Wash clothes in smaller batches.
• Clean the machine regularly: Using a cleaner once a month prevents buildup that forces the motor to overwork. Try using safe cleaners like those mentioned in our guide on the Best Washing Machine Cleaners of 2025.
• Check the drum and belts: A stuck drum can burn out the motor quickly.
• Run balanced loads: Uneven distribution of laundry stresses the motor.
• Perform routine maintenance: Follow your model’s manual or see our detailed LG Washing Machines Guide, Tips, Types & Maintenance.

Personal Suggestion

If you are a renter or student, replacing a motor might not be worth the investment. Consider smaller, portable washers instead, since they are easier to maintain and cheaper to replace. Families, on the other hand, may find repair a cost-effective option if the washer is under five years old.

Conclusion

Spotting a faulty motor before it fails is crucial for washing machine repair. Early signs like strange noises, burning smells, or a drum that won’t spin should never be ignored. While repairing the motor can save money, replacing the entire washer may be smarter for older units. By following preventive tips, such as avoiding overloads and performing regular cleaning, you can extend your washer’s lifespan and avoid sudden breakdowns.
