A Dishwasher fire might sound unusual, but it’s more common than most homeowners realize. Dishwashers combine three risky elements, heat, electricity, and water, and when a single component fails, it can lead to a devastating fire.
In Salt Lake City, where many homes feature modern appliances that run overnight or while residents are away, the potential for an unnoticed Dishwasher fire increases significantly.
At PuroClean of Layton, we’ve seen firsthand the aftermath of appliance-related fires that could have been prevented with simple awareness and maintenance. In this guide, we’ll uncover the seven hidden dangers behind dishwasher fires, explain how to recognize warning signs, and share expert tips to protect your home and family.

Dishwasher Fire: Why It Happens More Often Than You Think
A Dishwasher fire occurs when electrical components overheat, insulation fails, or moisture causes short circuits. According to the National Fire Protection Association (NFPA), kitchen appliances are responsible for over 20% of all residential fires in the U.S., with dishwashers accounting for a growing share (NFPA).
The U.S. Consumer Product Safety Commission (CPSC) has recorded thousands of dishwasher-related fires caused by faulty wiring, heating elements, and control panels (CPSC). Many of these fires start quietly, often during the drying cycle, when heat builds up inside the machine.
PuroClean Tip: Never leave your dishwasher running when you’re asleep or not at home. Even modern dishwashers can malfunction without warning.
1. Faulty Electrical Wiring and Heating Elements
Electrical wiring failures are one of the leading causes of Dishwasher fire incidents. Over time, connections can loosen, wires can fray, or insulation may degrade from moisture exposure.
The Occupational Safety and Health Administration (OSHA) emphasizes that faulty wiring and damaged cords are major electrical hazards, particularly in wet environments (OSHA).
Most dishwashers use heating elements to dry dishes. When these elements overheat or malfunction, they can ignite nearby plastic components or trapped grease.
Pro Tip: If you notice sparks, a burning smell, or the dishwasher repeatedly trips the circuit breaker, disconnect it immediately and call a certified technician.
2. Moisture and Water Intrusion
It might sound ironic, but water inside your dishwasher can be a fire hazard. Leaks from hoses or door seals can allow moisture to reach electrical wiring or the control board, creating a short circuit that leads to a Dishwasher fire.
The Federal Emergency Management Agency (FEMA) warns that water-damaged electrical components should never be used, as they can cause fires long after appearing dry (FEMA).
PuroClean Insight: If you suspect your dishwasher has a leak, have it inspected immediately. Preventing moisture intrusion is one of the most effective ways to avoid appliance fires.
3. Faulty Door Latches or Switches
A dishwasher’s door latch not only keeps water inside, it also signals the unit to start or stop. When this latch malfunctions, the machine may continue running even when open or fail to shut off heat cycles.
The Underwriters Laboratories (UL), which tests appliance safety, reports that many dishwasher recalls stem from electrical failures in the door latch assembly (UL).
Homeowner Tip: If your dishwasher continues to run after being opened or doesn’t stop mid-cycle, it could be a sign of an electrical short or damaged switch, both precursors to Dishwasher fire risk.
4. Build-Up of Grease, Food, and Plastic Residue
Even though dishwashers clean dishes, they aren’t self-cleaning. Over time, grease, food particles, and melted plastic can accumulate near heating elements. When the machine heats up during the drying cycle, these residues can ignite.
The Environmental Protection Agency (EPA) warns that grease residue and debris buildup increase the risk of fire in all kitchen appliances (EPA).
PuroClean Tip: Wipe down your dishwasher’s door seal and heating element monthly. Run a cleaning cycle using white vinegar or a dishwasher cleaner to remove hidden residue.
5. Overloaded Circuits and Outlet Problems
Plugging your dishwasher into an overloaded circuit or using the same outlet as other high-energy appliances increases the risk of electrical overload and Dishwasher fire.
The National Electrical Code (NEC) and NFPA recommend using a dedicated 15-amp or 20-amp circuit for dishwashers to prevent overheating and short circuits (NFPA).
Pro Tip: If your lights flicker or breakers trip when the dishwasher runs, contact an electrician to assess your circuit load and outlet condition.
6. Manufacturer Defects and Recalls
Dishwasher recalls are more common than many homeowners realize. Several major brands, including Bosch, Whirlpool, GE, and KitchenAid, have recalled models due to control panel malfunctions and overheating components.
The CPSC regularly issues recall notices for dishwasher models linked to fire hazards, and many of these units remain in homes today (CPSC).
Homeowner Action Step: Check the model and serial number on your dishwasher and visit the CPSC recall database to verify whether your appliance is affected.
7. Lack of Maintenance and Cleaning
The final, and most preventable, cause of a Dishwasher fire is neglect. Routine maintenance keeps your appliance running safely and efficiently. Dust, lint, and food particles in vents or behind the machine can ignite if exposed to heat.
According to the NFPA, unmaintained appliances are involved in 31% of all household fires (NFPA). Regular cleaning and inspections drastically reduce this risk.
PuroClean Tip: Every three months, pull out your dishwasher to vacuum behind it and inspect for frayed cords, residue, or moisture buildup.
Signs Your Dishwasher May Be a Fire Hazard
Recognizing warning signs early can prevent disasters. If you notice any of the following, unplug your appliance immediately and contact a professional:
- Burning or plastic odors during or after cycles
- Smoke or sparking from under the unit
- Excess heat or melted plastic inside the tub
- Leaks or visible corrosion on electrical components
- Unusual noises or vibration when operating
PuroClean Insight: When in doubt, schedule an appliance inspection. A quick checkup costs far less than repairing fire or smoke damage later.
What to Do If a Dishwasher Fire Occurs
Even with precautions, accidents can happen. Knowing what to do can save lives and minimize property loss.
- Shut off power immediately. Turn off the circuit breaker for the dishwasher or unplug it if safe to do so.
- Use a fire extinguisher. Only use a Class C extinguisher (for electrical fires). Never use water on electrical fires.
- Evacuate the home. If smoke spreads, leave immediately and call 911.
