Putting an electric kettle in the dishwasher is generally not recommended due to electrical components and seals that can be damaged by water and heat. While some detachable parts like lids or filters may be dishwasher-safe, the main body should always be hand-washed to ensure longevity and safety.
If you’ve ever stood over your electric kettle after a busy morning of tea, coffee, or instant oatmeal, wondering whether you can just toss it in the dishwasher like your mugs and spoons—you’re not alone. It’s a common question, especially in households where convenience rules and time is short. After all, dishwashers are designed to make our lives easier, right? But when it comes to electric kettles, the answer isn’t as straightforward as you might hope.
Electric kettles are marvels of modern kitchen engineering. They heat water quickly, often with precise temperature controls, and come in sleek designs that complement any countertop. But beneath that polished exterior lies a complex system of electrical components, heating elements, and safety mechanisms—none of which are meant to withstand the high-pressure sprays, extreme heat, and harsh detergents inside a dishwasher. So while it might seem like a time-saver, putting your electric kettle in the dishwasher can actually do more harm than good.
In this guide, we’ll explore why dishwasher cleaning is risky for most electric kettles, what parts (if any) can safely go through a cycle, and how to properly clean and maintain your kettle to keep it running smoothly for years. Whether you’re a daily tea drinker or just use your kettle occasionally, understanding the right way to care for it will save you money, prevent malfunctions, and ensure your water always tastes fresh.

Why You Shouldn’t Put an Electric Kettle in the Dishwasher
The short answer? You shouldn’t put the main body of an electric kettle in the dishwasher—ever. But why exactly is that? Let’s break it down.
Electric kettles are not like regular pots or pans. They contain electrical components that are sealed to prevent water from entering during normal use, but they are not designed to be submerged or exposed to high-pressure water jets. The base of the kettle, which houses the heating element and electrical connections, is particularly vulnerable. Even if your kettle has a removable base (like some cordless models), the main chamber still contains sensitive parts that can be damaged by dishwasher conditions.
One of the biggest risks is water intrusion. Dishwashers use hot water and steam to clean dishes, and even a small amount of moisture getting into the electrical compartment can cause short circuits, corrosion, or complete failure. Over time, repeated exposure—even if the kettle seems to work after one cycle—can weaken seals and gaskets, leading to leaks or electrical hazards.
Another concern is the high heat inside dishwashers. Most dishwashers reach temperatures between 140°F and 160°F (60°C–70°C) during the wash and rinse cycles, and even higher during the drying phase. While this is great for sanitizing dishes, it can warp plastic components, melt adhesives, or damage the internal lining of your kettle. Stainless steel kettles may fare better in terms of structural integrity, but the electrical parts remain at risk.
Additionally, dishwasher detergents are formulated to cut through grease and food residue, which means they’re often alkaline and abrasive. These chemicals can degrade rubber seals, discolor finishes, and leave behind residues that affect the taste of your water. Even “gentle” or eco-friendly detergents can be too harsh for the delicate materials used in electric kettles.
Finally, there’s the issue of mechanical stress. Dishwashers use powerful spray arms that blast water from multiple angles. This force can dislodge internal components, crack lids, or damage the spout. Kettles are not designed to be jostled around like plates or utensils, and the tumbling action can cause wear and tear over time.
In short, the combination of heat, water pressure, chemicals, and movement makes the dishwasher a hostile environment for electric kettles. Even if your kettle survives one cycle, you’re gambling with its lifespan and safety.
What the Manufacturers Say

When in doubt, always consult your kettle’s user manual. Manufacturers are the best source of truth when it comes to cleaning instructions, and most explicitly warn against dishwasher use for the main body of the kettle.
For example, popular brands like Breville, Cuisinart, and Hamilton Beach consistently state in their manuals that the kettle itself should not be placed in the dishwasher. Instead, they recommend hand washing with mild detergent and a soft cloth. Some models, particularly those with removable lids or built-in filters, may specify that those parts are dishwasher-safe—usually on the top rack only.
Take the Breville BKE820XL Smart Kettle, for instance. Its manual clearly states: “Do not immerse the kettle or base in water or place in a dishwasher.” Similarly, the Cuisinart CPK-17 PerfecTemp kettle warns against dishwasher cleaning for the main unit, though it notes that the lid and filter can be washed separately.
Why do manufacturers take such a firm stance? Because they design their products with specific tolerances and materials that aren’t meant to withstand dishwasher conditions. Even if a kettle appears to be made of sturdy stainless steel, the internal wiring, temperature sensors, and sealing gaskets are precision components that can fail under stress.
Ignoring these guidelines doesn’t just risk damaging your kettle—it can also void your warranty. Most manufacturers include clauses that deny coverage for damage caused by improper cleaning methods, including dishwasher use. So if your kettle stops working after a trip through the dishwasher, you’re likely on your own.
That said, some newer models are starting to include dishwasher-safe components. For example, the Russell Hobbs Retro Quiet Electric Kettle has a removable limescale filter that’s labeled as dishwasher-safe. Always check the label or manual to confirm, and never assume that because one part is safe, the whole kettle is.
In summary, manufacturer instructions are clear: the main body of an electric kettle should never go in the dishwasher. Only specific, detachable parts may be safe—and even then, only under certain conditions.
Parts That Might Be Dishwasher-Safe (and How to Know)
While the main body of your electric kettle should always be hand-washed, some components may be safe for the dishwasher—if they’re designed for it. The key is knowing which parts are removable and which are labeled as dishwasher-safe.
The most common dishwasher-safe part is the lid. Many kettles have lids that can be removed for cleaning, especially models with built-in filters or viewing windows. If your lid pops off easily and doesn’t contain electrical components (like a temperature display or LED lights), it’s likely safe to wash separately. Check for a symbol or note in the manual indicating “dishwasher safe” or “top rack only.”
Another part that’s often dishwasher-safe is the limescale filter. This small mesh screen sits inside the spout and catches mineral deposits from hard water. Over time, it can become clogged with scale, affecting water flow and taste. Many manufacturers design these filters to be removable and washable. For example, the Smeg KLF01 kettle includes a filter that can be rinsed under running water or placed in the dishwasher on a gentle cycle.
Some kettles also have detachable bases or cordless designs where the heating element is in the base, and the kettle lifts off for pouring. In these cases, only the kettle portion (not the base) might be considered for cleaning—but even then, it’s usually not recommended for the dishwasher. The base, which contains the electrical components, should never be submerged or exposed to water.
To determine if a part is dishwasher-safe, look for:
– A dishwasher-safe symbol (often a glass and water droplet icon)
– Instructions in the user manual
– Labels on the part itself
If you’re unsure, it’s always safer to hand wash. Use warm soapy water and a soft brush to clean filters and lids, then rinse thoroughly and air dry.
One tip: even if a part is labeled dishwasher-safe, consider washing it by hand occasionally. Dishwashers can leave behind detergent residues or cause gradual wear, especially on plastic components. Hand washing gives you more control and helps preserve the part’s integrity.
How to Properly Clean Your Electric Kettle
Cleaning your electric kettle the right way ensures it stays efficient, safe, and free of odors or scale buildup. Here’s a step-by-step guide to keeping your kettle in top condition.
Daily and Weekly Cleaning
After each use, wipe the exterior with a damp cloth to remove fingerprints, water spots, or dust. For stainless steel kettles, use a microfiber cloth to prevent scratching. Avoid abrasive cleaners or steel wool, which can damage the finish.
Once a week, give the interior a quick rinse with warm water. If you notice any residue or cloudiness, add a few drops of mild dish soap, swirl it around, and rinse thoroughly. Never let soap sit in the kettle for long, as it can leave a soapy taste.
Deep Cleaning and Descaling
Hard water leaves behind mineral deposits (limescale) that can affect performance and taste. Descaling should be done monthly, or more often if you live in a hard water area.
The most effective and natural descaling method uses white vinegar. Here’s how:
1. Fill the kettle halfway with equal parts water and white vinegar.
2. Let it sit for 1–2 hours (or overnight for heavy buildup).
3. Bring the solution to a boil, then turn off the kettle and let it cool.
4. Pour out the solution and rinse the kettle thoroughly with clean water.
5. Run 1–2 cycles with fresh water to remove any vinegar taste.
Alternatively, you can use a commercial descaling solution, following the manufacturer’s instructions. Avoid using lemon juice alone, as it’s less effective than vinegar and can leave residues.
Cleaning the Exterior and Base
For the outside, use a soft cloth dampened with water or a mild cleaner. For stainless steel, a paste of baking soda and water can remove stubborn stains. Avoid spraying water near the base or electrical connections.
The base should only be wiped with a dry or slightly damp cloth. Never submerge it or use excessive water.
Cleaning Removable Parts
If your kettle has a removable lid or filter, wash them with warm soapy water and a soft brush. Rinse well and dry completely before reassembling.
Tips for Long-Term Care
– Always empty the kettle after use to prevent mineral buildup.
– Store it with the lid open to allow airflow and prevent odors.
– Avoid overfilling, which can cause spills and damage the base.
– Use filtered water to reduce scale and extend the kettle’s life.
Risks of Dishwasher Cleaning
Putting your electric kettle in the dishwasher might seem harmless, but the risks are real and can lead to costly consequences.
First, there’s the risk of electrical damage. Even if your kettle appears dry after a cycle, moisture can seep into tiny gaps and corrode internal components. This can cause the kettle to stop heating, short-circuit, or even pose a fire hazard.
Second, seals and gaskets can degrade. These rubber or silicone parts keep water from leaking and protect electrical connections. Dishwasher heat and detergents can cause them to crack, shrink, or lose elasticity, leading to leaks.
Third, finishes can be damaged. Painted or coated kettles may peel or discolor. Stainless steel can develop water spots or rust if not dried properly after a dishwasher cycle.
Fourth, warranties can be voided. Most manufacturers won’t cover damage caused by improper cleaning. If your kettle fails after a dishwasher run, you’ll likely have to replace it out of pocket.
Finally, performance can decline. Scale buildup, warped parts, or damaged sensors can affect heating speed, temperature accuracy, and water taste.
In short, the short-term convenience isn’t worth the long-term risks. Hand washing takes just a few minutes and keeps your kettle safe and functional.
Best Practices for Electric Kettle Maintenance
To get the most out of your electric kettle, follow these best practices:
– Descale regularly: Monthly descaling prevents buildup and maintains efficiency.
– Use filtered water: Reduces minerals and extends the kettle’s life.
– Hand wash only: Clean the interior and exterior with mild soap and water.
– Check removable parts: Wash filters and lids separately as needed.
– Store properly: Keep the lid open and the base dry.
– Follow the manual: Always refer to manufacturer guidelines for care and cleaning.
By treating your kettle with care, you’ll enjoy faster boiling, better-tasting water, and a longer lifespan.
Conclusion
So, can you put an electric kettle in the dishwasher? The answer is a clear and resounding no—at least not the main body. While some detachable parts like lids or filters may be safe for the dishwasher, the electrical components, seals, and finishes of your kettle are not built to withstand the harsh conditions inside a dishwasher.
Hand washing is the safest, most effective way to clean your electric kettle. It protects the internal mechanisms, preserves the finish, and ensures your kettle continues to perform reliably. Plus, it only takes a few minutes and can be done while you’re cleaning other dishes.
Remember, your electric kettle is an investment in convenience and quality. Treat it well, and it will serve you hot water for years to come. Skip the dishwasher, follow the manufacturer’s instructions, and enjoy every cup with confidence.
