This odor may indicate a potential issue with your appliance that requires immediate attention.
In this troubleshooting guide, we’ll explore common reasons why your dishwasher might smell like burnt plastic and provide step-by-step solutions to help you identify and resolve the problem.
Why Does My Dishwasher Smell Like Burnt Plastic (Solved)
Dishwasher odors like burnt plastic are usually caused by food debris, clogged filters, and drainage issues.
So now we have answered the main question, let’s dive into troubleshooting.
Check for Foreign Objects:
Sometimes, plastic items or other foreign objects can accidentally fall onto the dishwasher’s heating element or near the pump during a wash cycle.
When the dishwasher operates and heats up, these objects can melt or burn, causing an unpleasant smell. Follow these steps to address this issue:

Inspect Dishwasher Racks and Utensil Baskets:
The dishwasher racks and utensil baskets are made of plastic, and over time, they can get damaged or warped due to high heat or improper loading.
When the damaged plastic comes into contact with the heating element, it may create a burnt plastic smell. Follow these steps to address this issue:
Examine the dishwasher racks and utensil baskets for any visible signs of damage or warping.
If you find any damaged parts, replace them with manufacturer-approved replacements.
Avoid overloading the racks and baskets to prevent additional damage.
Check the Dishwasher Motor or Pump:
A malfunctioning dishwasher motor or pump can overheat and cause plastic components within them to burn, leading to the smell of burnt plastic.
Follow these steps to address this issue:
- Listen for unusual noises during the wash cycle, which might indicate a problem with the motor or pump.
- If you suspect an issue with the motor or pump, it’s best to contact a professional technician to diagnose and repair the problem.
Inspect the Dishwasher’s Electrical Components:
Electrical issues within the dishwasher can also lead to the smell of burnt plastic. Follow these steps to address this issue:
Turn off the dishwasher and disconnect it from the power supply.
Carefully examine the dishwasher’s electrical components, including the control panel and wiring, for signs of damage or burning.
If you notice any damaged electrical parts, refrain from attempting repairs yourself and contact a qualified technician.
Clean the Dishwasher Interior:
Sometimes, a buildup of food debris, grease, or mold inside the dishwasher can produce unpleasant odors. Follow these steps to address this issue:
Remove any leftover food particles from the dishwasher’s interior, including the filter, spray arms, and drainage area.
Run an empty dishwasher cycle with a dishwasher cleaner or a mixture of vinegar and baking soda to eliminate odors and sanitize the appliance.
