Open dishwasher with a third rack and stainless steel tub in a kitchen

How to Choose the Right Dishwasher for Your Home

Dishwashers all look the same from the front: a rectangle of stainless steel with a handle. The differences are entirely on the inside, and there are really only four specs that separate a machine you’ll be happy with from one that quietly annoys you for the next decade.

Here they are, in the order they matter.

1. Tub material: stainless or plastic

Open the door and look at the interior. It’s either stainless steel or plastic (usually described as "polypropylene"). This single detail tells you more about a dishwasher than the brand does.

A stainless tub:

Dries better. Stainless holds heat, so at the end of the cycle the hot tub walls evaporate the water off your dishes. This is the main reason cheap dishwashers leave everything wet.
Runs quieter. Metal damps sound better than plastic, which drums.
Doesn’t stain or hold odors. Plastic tubs discolor over time and can hold a smell.
Lasts longer.

Stainless tubs typically start around the $500–$600 mark. Below that, you’re usually getting plastic. If you can stretch to a stainless tub, do it. It’s the best money in the machine.

2. Sound rating (dBA): the spec you’ll notice every day

Dishwasher noise is measured in decibels (dBA), and lower is quieter. The scale is deceptive, though, because it’s logarithmic: a 10 dBA drop sounds roughly half as loud to your ear.

dBA	What it sounds like	Verdict
60–65	Clearly audible across the room. You’ll turn the TV up	Budget machines. Avoid in an open plan
50–54	Noticeable but not intrusive	Fine in a closed kitchen
45–49	A soft hum. You know it’s on	The value sweet spot
40–44	Barely audible from a few feet away	Genuinely quiet. Worth it in open plans
Under 40	You have to check the indicator light	Diminishing returns for most people

This is the one spec people underrate before buying and complain about afterward. If your kitchen opens onto a living area, and most modern homes do, the dishwasher runs while you’re talking, watching TV, or working. There’s a full breakdown of what quiet actually costs in are quiet dishwashers worth the extra cost?

3. Racks: where usable capacity actually comes from

Every dishwasher is 24 inches wide. What changes is how cleverly the inside is arranged.

Adjustable upper rack. Raise or lower it to fit tall wine glasses or, more importantly, tall pots below. Nearly essential.
Fold-down tines. Let you flatten rows to fit mixing bowls, sheet pans, and awkward items. Cheap machines have fixed tines and you fight them constantly.
A third rack. A shallow tray across the top for cutlery, spatulas, and small lids. It frees the cutlery basket space below and is one of the genuinely great dishwasher features of the last decade. Worth paying for.
Cutlery basket vs. cutlery tray. Some brands put silverware in a top tray instead of a basket. Cleans better, uses top-rack space. A matter of preference.

Rack flexibility is worth more than a bigger "place setting" number on the box. A 14-place machine with fixed tines can be harder to load than a 12-place machine that adjusts.

4. Filter type: this one you have to live with

Dishwashers deal with food debris in one of two ways:

Hard food disposer (grinder). A small blade chops debris so it washes away. You never clean anything. It also makes noise, and it’s the main reason older and cheaper dishwashers are loud.

Filter (manual). A removable mesh filter catches debris. It’s much quieter, and it’s what every quiet dishwasher uses. But you have to twist it out and rinse it, realistically every month or two.

Almost everyone should choose the filter. Just know the deal: quiet dishwashers require you to clean the filter, and a neglected filter is the number one cause of "my dishwasher stopped cleaning well." Two minutes under the tap, every few weeks. See why your dishwasher might not be cleaning properly.

Drying: why your dishes come out wet

The most common dishwasher complaint, and it’s usually not a defect.

Condensation drying (most modern machines): the hot stainless tub evaporates water off the dishes. It’s energy-efficient and it works well on glass and ceramic, but it leaves plastic wet, because plastic doesn’t retain heat. That’s physics, not a fault.
Heated dry (an element in the bottom): dries everything including plastic, but uses more energy and can warp lightweight plastics.
Fan-assisted / zeolite drying (premium): the best results, and the reason some expensive dishwashers really do dry better.

The fix that costs $6: use rinse aid. It breaks water’s surface tension so it sheets off instead of beading. In a condensation-drying dishwasher, rinse aid is not optional, it’s part of how the machine is designed to work. Most "bad drying" complaints are an empty rinse aid dispenser.

Features you can ignore

Wi-Fi and app control. You are standing in front of it when you load it. It adds a control board that can fail.
A dozen wash cycles. You will use Normal, Heavy, and maybe Rinse. Forever.
"Bottle jets" and specialty sprayers. Rarely used after the first month.
Sanitize cycle. Nice to have (it’s NSF-certified high-temp), genuinely useful with baby bottles or illness, but not worth a big premium on its own.
Third-party "place setting" claims. Load your actual dishes at the store if you can.

Same principle as everywhere else: pay for the tub, the sound insulation, and the racks, not the software.

What to spend

Budget	What you get	Recommended?
$300–$450	Plastic tub, 60–65 dBA, fixed tines, grinder	Only for a rental or a garage
$500–$700	Stainless tub, 47–52 dBA, adjustable rack, filter	The value sweet spot
$700–$1,000	44–46 dBA, third rack, better drying	Worth it for an open-plan kitchen
$1,000–$1,600	Under 44 dBA, fan/zeolite drying, panel-ready	Diminishing returns unless you want the panel

The jump from $400 to $600 buys you more real improvement than the jump from $900 to $1,500. And a scratch-and-dent dishwasher is a strong buy for the same reason a scratch-and-dent range is: the only visible surface is the front panel, and a dent on the side vanishes the moment it slides between your cabinets. See what "scratch and dent" really means.

Before you buy: fit and install

Standard size is 24 inches wide, about 24 in. deep and 34–35 in. tall (adjustable feet). Compact 18-inch models exist for small kitchens.
Measure the cabinet opening, and check the door has room to open fully, especially near an island or a perpendicular cabinet.
Check the plumbing: hot water supply, a drain connection, and a power supply (hardwired or an outlet under the sink).
Panel-ready models take a cabinet front to disappear into the kitchen. They cost more and need a custom panel. A remodel decision, see best cooking appliances for a kitchen remodel.

And once it’s in, how you load it genuinely affects how clean things get, most people are doing it wrong.

Frequently asked questions

What should I look for when buying a dishwasher?

Four things, in order: a stainless steel tub (dries better, quieter, lasts longer), the sound rating in dBA (44 or lower for an open-plan kitchen), rack flexibility (adjustable upper rack, fold-down tines, ideally a third rack), and a filter rather than a grinder. Everything else is secondary.

Is a stainless steel tub worth it in a dishwasher?

Yes, it’s the best value upgrade in the machine. Stainless holds heat, so it dries dishes far better than a plastic tub, it’s noticeably quieter, it doesn’t stain or hold odors, and it lasts longer. Stainless tubs generally start around the $500 to $600 price point.

How quiet should a dishwasher be?

For an open-plan kitchen, aim for 44 dBA or lower, which is barely audible from a few feet away. In a closed kitchen, 47 to 50 dBA is perfectly fine. Anything at 60 dBA or above is clearly audible across the room and you’ll notice it every time it runs.

Why does my dishwasher leave dishes wet?

Most modern dishwashers use condensation drying, where the hot stainless tub evaporates water off the dishes. It works well on glass and ceramic but leaves plastic wet, since plastic doesn’t hold heat. The fix is rinse aid, which makes water sheet off instead of beading, and it’s essential rather than optional on these machines.

Do I have to clean my dishwasher filter?

If it has a filter rather than a grinder, yes, roughly every month or two. It takes two minutes: twist it out and rinse it under the tap. A clogged filter is the single most common reason a dishwasher stops cleaning well. Quiet dishwashers all use filters, so this is the price of quiet.

Is a third rack worth it?

Yes, it’s one of the genuinely good dishwasher features. The shallow top tray takes cutlery, spatulas, and small lids, which frees up real estate in the racks below. It meaningfully increases how much you can fit in a single load.

How much should I spend on a dishwasher?

$500 to $700 is the sweet spot: stainless tub, reasonable sound rating, adjustable racks. Below $450 you’re buying a plastic tub and a loud machine. Above $1,000, you’re paying for the last few decibels and panel-ready styling rather than better cleaning.
