Dishwasher Has Burning Smell: 7 Common Reasons (Answered)

A dishwasher having a burning smell is commonly caused by blockages in the heating element or motor, wiring defects, or motor or bearing malfunctions.

Now we have answered the main question, let’s dive into troubleshooting.

Check for Foreign Objects:

Sometimes, small foreign objects like plastic wrappers, utensils, or broken glass can find their way into the dishwasher’s heating element or motor area.

These items may melt or catch fire when the dishwasher operates, causing a burning smell. Follow these steps to check for foreign objects:

  • Turn off the dishwasher and unplug it from the power source.
  • Inspect the heating element and the area around the dishwasher’s motor for any foreign objects.
  • Use tongs or pliers to remove any debris or foreign objects carefully.

Examine Dishwasher Wiring:

Frayed or damaged wiring within the dishwasher can lead to overheating and a burning smell. To examine the dishwasher’s wiring:

  • Disconnect the dishwasher from the power source.
  • Access the dishwasher’s internal wiring by removing the front or rear panel (refer to the user manual for guidance).
  • Inspect the wiring for signs of damage, such as burns, exposed wires, or melted insulation.
  • If you identify any damaged wiring, refrain from attempting repairs yourself. Contact a qualified technician to address the issue.

Inspect Dishwasher Motor:

A malfunctioning motor can also generate a burning smell in your dishwasher. Here’s how to inspect the dishwasher motor:

  • Unplug the dishwasher from the power outlet.
  • Locate the dishwasher motor, which is typically found at the bottom of the appliance.
  • Look for signs of overheating, like scorch marks or a burnt odor.
  • If you suspect a faulty motor, it’s best to consult a professional technician for further diagnosis and repair.

 

Verify the Dishwasher’s Pump and Motor Bearings:

Over time, the dishwasher’s pump and motor bearings can wear out or become damaged, leading to friction and burning smells.

Follow these steps to verify the condition of the pump and motor bearings:

  • Turn off the dishwasher and disconnect it from the power supply.
  • Access the dishwasher’s pump and motor assembly (consult the user manual for guidance).
  • Gently rotate the pump and motor assembly by hand and listen for any unusual noises or grinding sensations.
  • If you detect any issues with the bearings, seek assistance from a qualified technician to replace them.

Check for Overloaded Dishwasher:

Overloading the dishwasher with an excessive number of dishes can obstruct the spray arms’ movement, leading to poor water circulation and potential overheating.

To prevent this:

  • Load the dishwasher following the manufacturer’s guidelines, ensuring sufficient space between dishes.
  • Avoid stacking dishes too close to the heating element or blocking the detergent dispenser.
