What’s Causing Your Washing Machine Burning Smell? 5 Common Culprits and Solutions

1. Broken or Loose Drive Belt

In a washing machine, drive belts play a crucial role in transferring power from the motor to the drum, allowing it to rotate. Over time, these belts can become loose, wear out, or even snap due to frequent use. When this happens, the washer may stop spinning, and you might hear a squeaking noise or detect a burning odor.
If you’re comfortable with DIY repairs, tightening or replacing a drive belt is a task you can manage. Just remember to unplug the machine and shut off the power and water supply before starting. Your appliance manual should guide you on locating and accessing the belt.
For those who prefer professional assistance, an SD Appliance Repair technician can handle the repair, typically costing between $180 and $190.

2. Damaged Pulley

Washing machines with drive belts also rely on a pulley system to keep everything moving. The pulley helps the belt rotate the drum, which is essential for proper cleaning.
Over time, pulleys can wear out or develop rust, causing increased friction with the belt. This added resistance may lead to overheating, sometimes resulting in a burning odor.
If you’re comfortable handling repairs, replacing a damaged pulley is possible. The process involves unplugging the washer, disconnecting power and water, inspecting the pulley for wear, and installing a new one if necessary. However, if you’re unsure, a professional repair technician can handle the job efficiently.

3. Faulty Motor

The motor is a key component in a washing machine, driving essential functions like spinning and agitation. If it starts to fail, you might hear a humming noise or notice a burning odor—both signs that the machine should be unplugged immediately.
Since diagnosing and repairing motor issues involves working with electrical components, it’s best to leave this job to a qualified technician. Hiring an SD Appliance Repair professional for motor repairs typically costs between $360 and $440.

4. Blocked Drain Pump

The drain pump in a washing machine is responsible for expelling water after each cycle. However, over time, soap residue, lint, and grease can accumulate, potentially leading to blockages. One possible consequence? A noticeable burning odor coming from the machine.
In some situations, clearing a clogged drain pump is something you can handle yourself. Start by unplugging the appliance, shutting off the power and water supply, and referring to your user manual for instructions on accessing the pump. Once located, remove any debris causing the obstruction.
If the burning smell persists even after cleaning the pump, the issue could stem from other components like the belt, pulley, or motor. At that point, you may need to troubleshoot further or consult a professional for repairs.

5. Bad Electrical Connection

A burning smell from your washing machine could sometimes be linked to an electrical issue, such as a faulty power connection or damaged cord.
If you notice any signs of wear or damage on the power cord or outlet, discontinue use immediately. Unplug the machine, cut off power to the area, and contact a qualified electrician as soon as possible.
To prevent potential hazards, always ensure the washer is plugged directly into a dedicated wall outlet. Avoid using extension cords or power strips, as they can lead to electrical overload and increase the risk of fire.
