Picture this: you load the dishwasher after dinner, hit the start button, and head to bed thinking you’re saving time. Halfway through the night, you wake up to the smell of something burning. You rush to the kitchen and—yep, smoke is coming from the dishwasher. Sounds like a horror story, right?
You’d think, “How on earth could a machine that sprays water all over the place catch on fire?” It’s not like it’s a toaster or a grill. But here’s the truth: it can happen. Rarely, but it’s still possible.
So, can a dishwasher really catch fire?
The short answer? Yes. The long answer? It’s complicated. Dishwashers are electrical appliances with heating elements, wiring, and electronic control boards. When everything works as it should, no problem. But when one part malfunctions—say, a wire shorts out or a heating element overheats—that’s when fire risk creeps in.
And just to put things in perspective, dishwasher fires do happen often enough that there have been major recalls over the years. Companies like Bosch, Whirlpool, and KitchenAid have had to recall certain models because of electrical issues that posed a fire hazard.
So while it’s not like your dishwasher is a ticking time bomb, it’s something worth being aware of.
What are the common causes?
Here’s where things get interesting (or scary, depending on how you look at it). The most common culprits include:
Faulty wiring – Wires can fray or get damaged over time, especially with all the moisture and heat in a dishwasher.
Defective control boards – These little circuit boards are the brains of your dishwasher. If they malfunction, they can overheat or spark.
Heating element problems – If the element overheats, it can scorch nearby components.
Plastic components melting – Some parts inside are plastic, and if they get too hot… well, melted plastic plus electricity is a bad combo.
Lack of maintenance – Dirty filters, clogged vents, and grease buildup can sometimes contribute to overheating.
In other words, it’s usually not your fault—but poor upkeep or ignoring warning signs can make it worse.
Should you be worried?
Not overly. Think about it this way: millions of dishwashers run every single day without any issues. But just like you wouldn’t leave a candle burning when you go out, you shouldn’t assume an appliance is completely risk-free.
The key is awareness. If you know what to look out for, you’ll likely catch any problem long before it becomes dangerous.
Signs your dishwasher might be in trouble
Before a fire happens, there are often warning signs. Here are a few red flags to keep on your radar:
A burning smell while the machine is running (or even when it’s off)
Visible scorch marks or melted plastic inside the unit
The machine tripping your circuit breaker
Strange popping or crackling sounds
Excessive heat coming from the door or sides
If you notice any of these, turn it off, unplug it, and get it checked. Better safe than sorry.
How to lower the risk (without turning into a paranoid appliance owner)
Now for the good news: preventing dishwasher fires is actually pretty easy. Here’s what you can do:
Don’t run it overnight or when you’re not home. Yes, it’s convenient, but if something goes wrong, you won’t be there to catch it.
Clean it regularly. Remove food debris, clean the filter, and check for any blockages. Grease buildup can trap heat.
Inspect cords and plugs. If anything looks damaged, call a technician.
Stay updated on recalls. Manufacturers list recalls online. A quick check with your model number could save you a lot of trouble.
Use it as intended. Don’t overload it, don’t block the spray arms, and definitely don’t use random cleaning agents that weren’t designed for dishwashers.
Imagine this…
You run your dishwasher while you’re cooking dinner, and because you’re around, you hear a weird popping sound. You open it up, turn it off, and call a repair service. They fix a faulty wire, and that’s the end of it. Crisis averted—all because you were there to catch the issue early.
See? A little awareness goes a long way.
So, can a dishwasher catch on fire? Yes, but it’s rare. When they do, it’s usually due to a faulty part or poor maintenance. The good news is that by keeping an eye (and nose) out for warning signs, cleaning it regularly, and avoiding running it while you’re asleep or away, you’ll drastically lower the risk.
Your dishwasher is one of those appliances you rely on without thinking twice—but giving it a little attention can make all the difference.
