Why Should You Care About Your Washing Machine Motor?
Let’s be real: washing machines are the unsung heroes of our homes. But when your laundry overloads and your machine stops spinning, all bets are off. Most often, the culprit is the washing machine motor. Knowing how to check this crucial part can save you a fortune and keep your clothes fresh and happy.
Before you consider calling for professional help, why not play detective yourself? We’ll walk you through how to check your washing machine motor step-by-step – with no jargon, no technician required, and most importantly, no guesswork.
Spotting the Troubles: Symptoms of a Faulty Motor
The first step is listening. Yes, your washing machine actually talks – mostly in weird noises and frustration. Watch out for:
- Machine won’t start or makes a humming noise but refuses to spin or agitate
- Strange grinding or buzzing sounds during cycles
- Excessive vibration or the drum locks up mid-cycle
- Burnt smell or motor overheating
If you notice any of these, the motor might be waving a distress flag. But before you panic, keep calm and carry on reading.
Step 1: Safety First — Unplug and Prep
Did we mention unplugging the machine? Because shocking yourself doesn’t help anyone. Make sure your washer is completely powered off and unplugged from the wall.
Pull it out so you have access to the back panel. Gather your tools — a screwdriver, a multimeter, and maybe a trusty flashlight. Bonus points if you have a multimeter (India) or multimeter (Global) ready — more on this lifesaver soon.
Step 2: Visual Inspection of the Motor and Its Parts
Removing the back panel reveals the heart of the machine — the motor. Look for:
- Carbon brushes: These little guys wear down over time and can stop the motor from running smoothly. If they look short or burnt, it’s time for replacement.
- Signs of damage: Burn marks, corrosion, or loose wires around the motor and connectors are not good signs.
- Drive belt condition: While you’re at it, check the belt for cracks or slack — a worn belt can mimic motor problems.
A clean motor with solid connections sets the stage for proper testing. If things look grim, mark your calendar for ordering parts.
Step 3: Multimeter Magic — Testing Motor Windings
Here comes the science bit promised not to be scary.
Your washing machine motor has windings — coils of wire that generate magnetic fields to spin the drum. Testing these windings with a multimeter for continuity and resistance can tell you if the motor’s heartbeats are skipping.
How to Test Motor Windings:
- Disconnect the motor connector carefully.
- Set your multimeter to the resistance (ohms) mode.
- Touch the probes to the motor winding terminals.
- Look for a resistance reading similar to your washing machine’s manual specification (usually between a few ohms to several tens of ohms).
- Check for continuity — if the meter shows infinite resistance, the winding is broken.
- Compare windings if your motor has multiple to ensure they’re balanced.
This test helps distinguish between a healthy motor and one that’s toast. If you don’t have the manual, generic values can be found online, but always double-check with your specific model.
Step 4: Testing Rotation and Motor Speed
If you’re feeling adventurous and have a tachometer handy, test the motor’s rotation speed during a run cycle or on a test rig to check if it’s spinning at the correct RPM. For example, aiming the tachometer at a marked point on the pulley lets you verify the motor’s revolutions per minute, confirming if it runs as it should.
This step is more advanced but can reveal subtle motor performance issues invisible to the naked eye.
Step 5: Inspect Motor Sensors and Wiring
The motor isn’t an island. Sensors and wiring govern its function, so tracing wires for breaks or corrosion can uncover hidden gremlins. Sometimes a loose wire or faulty sensor is the real troublemaker, not the motor itself.
Pro Tips and Common Pitfalls
- Don’t forget to check the motor brushes — usually wear items that cause intermittent motor failure.
- Use videos like this washing machine motor diagnostic tutorial and stator testing guide to visually nail the process.
- When in doubt, test the motor in both clockwise and anticlockwise directions to confirm operation.
- If your washing machine is a specific brand like LG, Samsung, or Bosch, remember that motors and specs can vary. For warranty info or peculiar model quirks, check resources like our LG washing machine warranty or Samsung warranty guides.
Embrace these inspection rituals as your laundry lifesavers and keep your washing machine humming along.
When to Call in the Pros or Replace the Motor
After your tests, if you find:
- Broken windings or burnt brushes
- Motor not spinning despite power and proper connections
- Inconsistent or no resistance readings on the multimeter
- Overheating or burning smells during operation
It’s probably time to bite the bullet and replace the motor or get a professional technician onboard. The good news? Replacements and parts are widely available online — like motors and testing tools in India or global options including the USA.

Washing Machine Motor Testing: Final Spin
To sum it all up with a neat little package:
- Listen and watch for classic motor breakdown symptoms.
- Always unplug before peeking under the machine’s skirt.
- Visually inspect for worn brushes and loose wiring.
- Test motor windings with a multimeter according to specs.
- Check rotation and RPM with a tachometer if possible.
- Know when to replace or upgrade and shop smart.
Now go show that washing machine motor who’s boss — and enjoy your freshly cleaned laundry like the champ you are.
