The dishwasher is an essential kitchen appliance, but choosing the right model involves more than just comparing prices or picking the one with the most features. Capacity, noise level, cleaning performance, dimensions, and energy consumption—several factors can influence your long-term satisfaction.

Whether you are setting up a new kitchen, replacing an aging appliance, or simply looking for a model better suited to your lifestyle, it is important to take the time to assess your needs.

To help you make an informed decision, here are five questions to ask yourself before buying a dishwasher.

1. What capacity suits your daily life?

Before comparing models, start by considering the amount of dishware you use and how often you run a cycle.

The number of people in your household can provide an initial clue, but it isn’t the whole story. A person living alone who cooks every day may have different needs than a couple who frequently eats out. Conversely, a family that prepares several meals at home may require a larger capacity.

Think about your habits, not just the number of people

Ask yourself a few questions:

• How many meals do you prepare at home each week?

• Do you use a lot of pots, pans, and baking dishes?

• Do you frequently have guests over?

• Do you prefer to run the dishwasher every day, or wait until it’s full?

These habits will help you determine the capacity that’s right for you. A model with a well-organized interior can also make loading easier, even when you’re dealing with bulky dishware.

An interior layout that makes all the difference

The arrangement of the racks, adjustable supports, and the ability to change the height of the top rack can make loading much more convenient. Some models even include a third rack, typically designed for utensils and small accessories.

If you frequently use large pots, tall glasses, or serving dishes, check that the interior layout allows for them to be placed inside with ease.

A tip from Germain Larivière: Consider the dishware you use most often. A large-capacity appliance isn't necessarily the best choice if its interior layout doesn't align with your specific needs.

2. What noise level are you looking for?

Noise is a particularly important factor for kitchens that open onto a living room or dining room. If you enjoy cooking, watching television, or chatting while the dishwasher is running, its noise level can affect your comfort.

The noise level of a dishwasher is generally expressed in decibels (dB). The lower this value, the quieter the appliance—assuming comparable measurement conditions. Sébastien Chenel, an appliance buyer at Germain Larivière—quoted by La Presse on September 20, 2026—puts it plainly:

“It’s the first question consumers ask us: is it noisy?”

He’s right. A dishwasher running at 52 dB can be heard from the living room.
With a 44 dB model, you don’t even notice it’s there. It’s the factor that makes the biggest difference to your daily life—and the first thing to check on the spec sheet.

How should you interpret decibel levels?

For reference, here are a few benchmarks to help you compare different models:

• 45 dB or less: discreet and quiet. You can run the appliance even while having dinner.

• 46 to 49 dB: an appropriate sound level. Audible in an open-plan space.

• 50 dB and above: more noticeable. Less recommended if the kitchen opens onto the living room.
  

These values ​​are general guidelines, not a guarantee of the noise level actually perceived in your home. Installation, surrounding materials, and the selected program can also influence the result.

Silence: An Everyday Advantage

A quieter dishwasher can be a great benefit if you frequently run cycles in the evening or if your kitchen shares the same space as your living room.

Some appliances also offer a "silent" cycle or programs designed to run at specific times. However, be sure to check the model’s specifications: a quieter cycle may take longer to complete.

A tip from Germain Larivière: Don’t just compare the prices of different models. If you have an open-concept kitchen, the noise level deserves special attention, as you’ll likely hear your dishwasher running several times a week.

3. What washing and drying performance should you look for?

Above all, a dishwasher must clean your dishes effectively. However, performance can vary depending on the programs, the filtration system, the design of the spray arms, and the drying options.

The goal is to find an appliance that suits your habits, without paying for features you will rarely need.

Programs tailored to different needs

Depending on the model, you may find several programs:

• Normal cycle: designed for everyday dishwashing.

• Intensive cycle: intended for heavily soiled items or stubborn food residue.

• Quick cycle: useful when you want to shorten the wash time, depending on the intended use.

• Eco cycle: designed to reduce water and energy consumption, typically by taking more time.

• Delicate cycle: suitable for certain more fragile items, provided they are confirmed to be dishwasher-safe.

Some appliances also feature sensors that adjust cycle settings based on the detected level of soiling. The specific functions and their outcomes vary by model.

The drying system: a detail that matters

Drying is another factor to consider, especially if you frequently wash plastic containers or prefer to put your dishes away shortly after the cycle ends.

Technologies vary from one appliance to another. Some models rely on residual heat, while others incorporate additional drying systems, such as ventilation or automatic door-opening features.

Results can also depend on the materials. Plastic, for instance, generally retains less heat than ceramic or glass, which can make it more difficult to dry.

Filtration and Maintenance

The filtration system helps trap food particles during the wash cycle. Regularly cleaning the filter—in accordance with the manufacturer's recommendations—ensures the appliance continues to function properly.

Before making a purchase, check the maintenance instructions and ensure the filter is easy to access. Proper maintenance helps prevent the buildup of residue and unpleasant odors.

A tip from Germain Larivière: choose programs and options based on your actual habits. Factors such as how often you use pots and pans, the amount of plasticware you wash, or your desire to reduce resource consumption can help guide your decision.

4. What dimensions and installation requirements should you consider?

A dishwasher may have all the features you’re looking for, but it still needs to be compatible with your kitchen. Before choosing a model, take the time to measure the available space and check the installation requirements.

Measure the available space

Built-in dishwashers are often designed with standard dimensions, but it is important to verify the exact measurements for each specific model.

Take into account:

• The width of the available opening.

• The height under the countertop.

• The depth of the space and the necessary clearances.

• Door opening and access to adjacent cabinets.

• The space required for connections.

If you are replacing an existing appliance, do not assume that all models will have the exact same dimensions. Checking beforehand can help avoid complications during installation.

There are three available widths, and your choice will primarily depend on the space you have available.

• 18 inches (approx. 45 cm). Holds 8 to 10 place settings. A compact size—ideal for a condo housing 1–2 people, a basement, or a secondary kitchen. Currently the most popular size in Quebec.
• 24 inches (approx. 60 cm). Holds 12 to 14 place settings. The North American standard. Accommodates all sizes of plates and pots. The go-to choice for families.
• 30 inches (approx. 76 cm). Holds 14 or more place settings. A large-capacity unit, often featuring a third rack. Requires a wider counter opening—be sure to measure before ordering. Ideal for large families and entertaining.

Built-in or freestanding?

The choice depends primarily on your kitchen layout and the look you want to achieve.

A built-in dishwasher fits under the counter and between cabinets. It is designed for kitchens set up to accommodate this type of appliance, offering a more seamless, integrated appearance.

A freestanding dishwasher is designed to be installed without being fully integrated into the cabinetry, provided that the clearances and connections specified by the manufacturer are met. This option is suitable for layouts where a built-in installation is either not possible or not desired.

Depending on the brand and product line, some models also feature customizable panels, allowing the appliance to blend in more effectively with your kitchen cabinetry.

Don't forget the connections

Installation may require specific water supply, drainage, and electrical connections. If you are renovating your kitchen or switching to a different type of appliance, check the manufacturer’s requirements and, if necessary, consult a qualified professional.

Also, be sure to check what is included in the price; services such as delivery, installation, connection accessories, and the removal of your old appliance may be charged separately.

A tip from Germain Larivière: before you start shopping, measure your available space and take note of any constraints related to your current setup. This will allow you to compare models that are compatible with your kitchen right from the start.

5. What budget and features are worth it?

The price of a dishwasher can vary threefold. What makes the difference isn't the number of programs, but the quality of the components you can't see: the pump, the insulation, the drying system, and the availability of spare parts.

An entry-level model will get the job done. However, spending $300 more for a unit with a hot-air drying system and a 44 dB noise level will save you money on electricity and repairs—and spare you a lot of frustration. The best way to calculate value: divide the price by the number of years covered by the actual warranty. That’s the figure that really matters.

How to spot the best value for money: Look for a noise level of 45 dB or lower, a drying system that leaves dishes completely dry (not lukewarm and wet), a warranty of at least 2 years on the tub, spare parts available in Quebec, and a filter that can be accessed without tools. If it checks all five boxes, you’ve found your model.

Determine your priority features

Before comparing prices, make a list of your essential needs versus features that would simply be "nice to have."

Available options vary by model and may include:

• Adjustable racks: to make loading items of various sizes easier.

• Third rack: for organizing specific utensils and small accessories.

• Enhanced drying options: to ensure your dishes come out perfectly dry.

• Specialized programs: for specific types of dishware or levels of soiling.

• Connectivity: to access certain functions or receive notifications via your phone (where available).

Not all of these features are essential for every household. A simpler model may perfectly suit your needs, provided its performance and capacity are appropriate for you.

Compare water and energy consumption

Consumption is another factor to consider, especially if you use your appliance frequently.

Energy labels and information allow you to compare specific parameters across different models. Check the data provided for the appliances you are considering, while keeping in mind the programs used and the conditions under which the measurements were taken.

An "eco" cycle can help reduce water or energy consumption, though it often takes longer to complete. The actual outcome depends on the specific model and the program selected.

Consider the total cost

The purchase price is only one part of the total cost of ownership. To better compare your options, take several factors into account:

• The initial price and any applicable promotions.

• Water and electricity consumption.

• Installation and delivery costs.

• Warranty terms.

• Availability of spare parts and maintenance recommendations.

It is also worth checking the manufacturer’s warranty, including any exclusions and service conditions. This information will help you better understand the protection that comes with your purchase.

Finally, an extra feature does not necessarily justify a higher price. What matters is determining whether it truly enhances your day-to-day experience.

Advice from Germain Larivière: Set your budget before you begin your search, then compare models that meet your essential criteria. This way, you can invest in the features that truly matter to you.

6. Which brands or models should you avoid—and why?

The question comes up constantly: which dishwasher brand should you avoid? The honest answer is that no brand should be avoided entirely. It’s specific models within certain product lines that tend to cause issues. Here are some objective red flags to look for before making a purchase.

Objective red flags

• A noise level rating above 50 dB. Check the product specifications. Anything over 50 dB means the appliance will be audible from the next room—you’ll end up regretting it.
• Parts unavailable in Quebec. Ask the salesperson if components like the pump and control board can be ordered locally. If the answer is vague, move on to another option.
• A one-year warranty—and that’s it. A one-year warranty on the tub is very short for an appliance expected to last ten years. Two years or more is a reasonable minimum.
• A hard-to-reach filter. If you have to unscrew a panel just to clean the filter, the truth is, you simply won’t clean it.

And the appliance will start to smell bad within six months.

Expensive or proprietary consumables. Salt, rinse aid, detergent tablets: check that these are widely available, rather than being sold exclusively by the manufacturer.

Why a Brand Is Never Bad in Itself

A brand is never bad in itself: it's the model and the after-sales service that count. The same manufacturer can produce an excellent 24-inch model at 44 dB and a noisy entry-level model. What differentiates the two is the technical specifications and the service.

Sébastien Chenel, appliance buyer at Germain Larivière, sums it up:

High-end models cost more to buy, but they last longer and are repairable.

Over ten years, the poorly insulated "economy" model, repaired twice and replaced after six years, ends up costing more than the superior model purchased only once.

Germain Larivière's advice: compare models, not logos. And ask about spare parts availability before paying.

In summary: how to find the right dishwasher for you?

Choosing a dishwasher becomes simpler when you know your priorities. Before making your decision, keep these five questions in mind:

1. What capacity suits your daily life? Consider your cooking habits and the interior layout you need.

2. What noise level are you looking for? Take into account the layout of your home and when you typically use the appliance.

3. What washing and drying performance should you prioritize? Compare the available programs, drying systems, and maintenance requirements.

4. What dimensions and installation requirements should you consider? Measure the available space and check the necessary utility connections.

5. What is your budget, and which features are worth the investment? Focus on the characteristics that meet your specific needs, and compare energy consumption as well as warranty terms.

The best dishwasher isn't necessarily the most expensive one, nor the one with the most features. It’s the one that fits seamlessly into your kitchen, aligns with your habits, and delivers the performance you’re looking for.
