This comprehensive guide will help you understand the root cause, react properly, and maintain the longevity of your appliance while ensuring safety within your home.

Why is my dishwasher smoking? (10 Common Reasons Listed)

A smoking dishwasher can be a result of several underlying issues. Understanding the possible causes can help identify the problem and take corrective action. Here are some reasons why your dishwasher might be smoking:

  1. Wiring issues: Faulty or damaged wiring can lead to electrical malfunctions, overheating, and eventually, smoke. Inefficient wiring could also cause a short circuit, turning the dishwasher into a potential fire hazard. In such cases, it’s best to unplug the device immediately and consult an electrical professional for repairs.
  2. Heating element issues: The heating element in a dishwasher is responsible for maintaining water temperature and drying dishes. If it malfunctions, the temperature may rise excessively, causing plastic parts or leftover food particles to burn and produce smoke. A damaged heating element needs to be replaced to prevent further smoke or damage.
  3. Blocked filters: A clogged filter can restrict water flow and decrease the dishwasher’s efficiency. As a result, it may run longer and hotter, causing some components to become too hot and emit smoke. Regularly cleaning the filters is crucial to avoid this issue.
  4. Improper loading: Overloading the dishwasher or using inappropriate cleaning products may cause dishwashing detergent to foam excessively. The resulting suds can clog the dishwasher, create pressure, and eventually result in smoke. Refer to the user manual for loading guidelines and detergent recommendations.
  5. Foreign objects: Items like food debris, plastic, or even kitchen accessories can sometimes fall into the bottom of the dishwasher. If they contact the heating element, they may catch fire or melt, producing smoke. Check for any foreign objects regularly and remove them immediately.
  6. Mechanical failure: A broken motor, worn pump seals, or damaged internal components can lead to smoke emissions. It’s crucial to address these issues promptly by consulting an appliance repair professional.
  7. Wrong Dishwasher Detergent: If you accidentally use laundry detergent or dish soap instead of dishwasher detergent, it could cause excessive sudsing, overheating, and smokiness. Always make sure to use the appropriate type of detergent for your dishwasher.
  8. Detergent Overuse: Using too much dishwasher detergent can also cause excessive sudsing and subsequent overheating, especially in areas with soft water.
  9. Inappropriate Items: Washing items not safe for dishwasher use, such as certain types of plastic or wooden products, could lead them to warp, melt, or burn, resulting in smoke.
  10. Faulty Thermostat: A malfunctioning thermostat might not regulate the dishwasher’s temperature accurately, causing it to overheat and smoke.

In any case, if you notice your dishwasher is smoking, it’s wise to unplug it and contact a professional appliance repair service to determine the exact cause and prevent potential hazards.

Dishwasher smoking from control panel

Certainly. If your dishwasher is smoking from the control panel, it indicates that there may be a significant problem that requires immediate attention. Here are some likely causes:

Dishwasher smoking from control panel
  1. Electrical Malfunction: This is the most common cause of smoke coming from the control panel. It could be due to faulty wiring or a malfunctioning component.
  2. Water Intrusion: If the seal of the control panel becomes faulty, it could allow water to enter, leading to the formation of deposits on the conductors, which over time may lead to a short circuit and cause smoke.
  3. Damaged Control Board: The control board is like the brain of your dishwasher. If it becomes faulty due to a burned resistor, blown capacitor, or other malfunctions, it could result in smoke.

In all these scenarios, it would be best to disconnect the dishwasher’s power source and call an appliance repair professional immediately to diagnose and fix the problem. Continuing to use a smoking dishwasher could present a fire hazard and potential health risks.

Dishwasher burning smell during dry cycle

Sure, let’s delve into the common causes of a burning smell emanating from your dishwasher during the dry cycle:

  1. Heating Element: The primary suspect in such a scenario is the heating element. It helps in maintaining water temperature and drying the dishes. Faults in the heating element could lead to excessive temperature escalation during the drying cycle, causing a burning smell.
  2. Trapped Plastic: Objects stuck in your dishwasher, particularly plastic, can melt due to the appliance’s high temperature during the dry cycle.
  3. Motor Issues: Another possible cause can be a malfunctioning motor. When the motor of a dishwasher fails, it may lead to overheating and emit a burning smell.
  4. Defective Design and Craftsmanship: While less frequent, poor design and faulty manufacturing can also lead to burning smells from a dishwasher during the drying cycle.

Please note, if you notice a persistent burning smell during the dry cycle, it’s safest to turn off and unplug your dishwasher immediately. Get in touch with a professional for inspecting and addressing the issue.

Frequently Asked Question (FAQs)

Why is my dishwasher burning plastic?

Your dishwasher might be burning plastic due to foreign objects made of plastic trapped inside. These could melt during a wash or dry cycle due to the high temperatures involved. Plastic items could have fallen onto the heating element or gotten stuck in the bottom drain or filter. It’s crucial to regularly check your dishwasher for any foreign objects and remove them immediately to prevent this issue.

Why is there a burning smell in my dishwasher during the dry cycle?

A burning smell coming from your dishwasher during the dry cycle may be due to a malfunctioning heating element, which overheats during this cycle. Alternatively, trapped debris like food particles or plastic materials might burn due to the high temperatures during drying. Lastly, the smell could be due to a faulty motor that’s overheating. If there’s a persistent burning smell, it’s safe to disconnect the dishwasher and consult with a professional.

Can a faulty dishwasher cause a fire?

Yes, a faulty dishwasher can potentially cause a fire. Electrical faults, overheating appliances, short-circuits, or malfunctioning components can all lead to fires. Bad wiring or a defective control board are particularly risky. It’s essential to regularly inspect your dishwasher and conduct professional maintenance to prevent such hazards.

How do I get the smoke smell out of my dishwasher?

To get the smoke smell out of your dishwasher, start by thoroughly cleaning the interior and removing any debris. You can then run a cycle with a dishwashing-safe cleaning agent like white vinegar or a specialized dishwasher cleaner. Baking soda also works well in removing odors; sprinkle it at the bottom, let it sit overnight and run a short cycle the next day.

What is the normal life expectancy of a dishwasher?

The average lifespan of a dishwasher is between 7 to 12 years. This can vary based on the brand, model, usage frequency, and maintenance habits. Regular cleaning and timely repairs can help to maximize your dishwasher’s lifespan.

How do you know when your dishwasher is dying?

Your dishwasher might be nearing the end of its life if it’s not cleaning dishes thoroughly, makes unusual noises, or has frequent breakdowns. Other signs might include visible rust, water not draining correctly, the door not latching, or older age (usually 10 years or more). If you notice these signs, consider consulting with a professional or replacing the dishwasher.

Is it worth it to fix a dishwasher?

Whether it’s worth fixing a dishwasher depends on several factors: the cost of repairs, the age of the dishwasher, and the extent of the damage. Generally, if the repair costs more than half the price of a new dishwasher, or if the dishwasher is older than seven years and requiring frequent repairs, it might be more economical to replace it.

A smoking dishwasher is a serious issue that requires immediate attention.

Whether the cause of the smoke is mechanical failure, electrical problems, or improper dishwasher use such as overloaded detergent or wrong items being washed, it’s crucial to disconnect the dishwasher from the power source and call in a professional for a proper diagnosis and repair.

Regular maintenance and timely repairs go a long way toward ensuring the safety and longevity of your dishwasher. Remember, ignoring a smoking dishwasher can lead to not only appliance damage but also potential health and fire hazards.
