Dishwasher Smells Burnt

Quick answer

A burnt smell from your dishwasher is often due to trapped food debris or a dirty filter. Turn off power, clean the filter, and check the heating element. If the smell persists, inspect for electrical issues or a faulty component.

Confirm the symptom

• Burnt or electrical odor when the dishwasher is running
• Smell is strongest during the drying cycle
• No visible smoke or sparks, but a strong odor persists

Tools and prep

• Rubber gloves
• Plastic scraper
• Soft cloth or sponge
• Mild dish soap
• White vinegar or baking soda
• Flashlight
• Screwdriver (if needed for filter removal)

Step-by-step troubleshooting

1. Turn Off Power
   Do: Unplug the dishwasher or turn off the circuit breaker.
   Observe: Power is off and dishwasher is safe to handle.
   Means: Prevents electrical hazards during inspection.
   Next: Clean the filter and interior
2. Clean the Filter and Interior
   Do: Locate and remove the filter (usually at the bottom). Scrape off debris, rinse with water, and wipe the interior with a damp cloth.
   Observe: Filter is clean, and no debris remains inside.
   Means: Removes trapped food particles causing the smell.
   Next: Check the heating element
3. Check the Heating Element
   Do: Inspect the heating element (at the bottom of the tub) for discoloration or burning.
   Observe: Heating element shows signs of damage or burning.
   Means: A faulty heating element can emit a burnt smell.
   Next: Test the heating element with a multimeter if available
4. Test the Heating Element
   Do: Use a multimeter to test for continuity. If no continuity, the element is faulty.
   Observe: Multimeter shows no continuity or erratic readings.
   Means: A failed heating element needs replacement.
   Next: Replace the heating element if faulty
5. Inspect for Electrical Issues
   Do: Check wiring connections and control board for signs of burning or damage.
   Observe: Visible damage or burning on wires or the control board.
   Means: Electrical faults can cause a burnt smell and pose a fire risk.
   Next: Call a professional if damage is found
6. Run a Cleaning Cycle
   Do: Use a dishwasher cleaner or a vinegar solution to run a cleaning cycle.
   Observe: Smell is reduced or eliminated after the cycle.
   Means: Residue or mildew buildup may be the cause.
   Next: Monitor for recurring smells
7. Monitor for Recurring Smells
   Do: Run the dishwasher normally and observe if the smell returns.
   Observe: Smell persists or returns after cleaning.
   Means: May indicate a deeper issue requiring professional repair.
   Next: Call a professional
