How Reliable Are Dishwashers in 2025?

Quick Answer: Bosch is still a reliable dishwasher brand in 2025, but LG leads with the fewest service calls.

Before you start comparing racks and fancy drying tricks, here’s the question that really matters: Will it break?

At Yale, we keep this honest because we’re the ones showing up to fix it if it does.

Last year, we handled over 33,000 service calls across the region.

Here’s what the real numbers say based on sales divided by service calls:

The following service rates are based on a minimum of 100 products sold and a total sample of over 5,000 products within 12 months.

So what does that mean for your kitchen?

👉 LG is the most reliable, with less than 5% of units needing service last year. Bosch lands just below the average—solid, but not flawless.

Some brands like Fisher & Paykel and Café creep higher because they’re newer here and have quirks (and fewer service techs, too).

The kicker? It’s not just how often something breaks.

It’s whether someone will actually fix it where you live.

We service Bosch, LG, Thermador, KitchenAid, Miele, GE Profile, Beko, Café, and Fisher & Paykel throughout Greater Boston, Cape Cod, Southern NH, and Rhode Island.

Service is crucial before buying Bosch or any other brand. Most dealers do not offer it, so make sure you can get your dishwasher fixed in your area.

Installation is another factor. Always Google service and install before you buy.

ℹ️Quick Note on Thermador

You’ll see Thermador in the service numbers too, but here’s the inside scoop:

Thermador dishwashers are made by Bosch and share almost all the same parts and design. The main reason people buy a Thermador dishwasher is that it’s often free when bundled with a Thermador pro range or wall oven.

No cooking bundle? Just choose a Bosch dishwasher. It offers the same quality for a better value.

✅ Bottom Line: Bosch is still a great bet for a quiet, feature‑rich dishwasher with strong local service support. If reliability above all is your priority, put LG at the top of your list.

Bosch Dishwasher Series Comparison (2025)

What Makes Each Bosch Dishwasher Series Different?

Quick Answer: Each Bosch series adds upgrades in tub material, noise level, rack flexibility, and drying power, starting with basic features in the 100 Series and ending with premium touches in Benchmark.

• Tub: Stainless holds heat and doesn’t trap odors like plastic.
• Noise: The lower the decibels, the quieter. Below 44 dB is nearly silent.
• Racking: RackMatic means adjustable upper rack. MyWay is a deep third rack for mugs and bowls.
• Drying: Condensation is standard. AutoOpen and CrystalDry help dry plastics better.
• Leak Protection: AquaStop uses sensors to shut off water if there’s a leak.

Do You Really Need the Bosch HomeConnect App?

Quick Answer: You don’t need the HomeConnect app for everyday use, but it unlocks smart features like PowerControl, remote start, and cycle notifications.

Every Bosch dishwasher from the 300 Series up is “smart,” meaning it can connect to Wi-Fi through Bosch’s HomeConnect app.

Yet, you don’t need the app for everyday washing. Just pick your cycle on the machine and hit Start.

But the app does unlock a few extras, like PowerControl (targeted spray power in the 800/Benchmark), custom cycles, push notifications when your cycle’s done, or remote start if you’re out.

If you like tech or have other Bosch smart appliances, it’s handy. It’s also secure and stable enough that we rarely see issues.

But if you’re the “just press Start and walk away” type, you can skip it entirely.

What’s the Difference Between Bosch Overflow Protection and AquaStop?

Quick Answer: Overflow Protection shuts off water inside the tub, while AquaStop adds full leak sensors and a shutoff valve to protect your floors.

Overflow Protection (like on the Bosch 100 Series) is a basic safety float inside the tub. If too much water builds up, it shuts off the water inside the dishwasher.

It’s handy for clogs or overfilling but won’t catch a leak in a hose or valve.

AquaStop (on the 300 Series and up) is Bosch’s full leak prevention system.

It uses extra sensors in the base and a special double-walled hose with an automatic shut-off valve.

If water escapes anywhere, whether inside the tub or under your cabinets, AquaStop cuts the water at the source before it floods your floors.

💡 Pro Tip: AquaStop leak protection is smart insurance if you live in a tower at the Seaport or the third floor of a condo in the South End.

Nobody wants dishwasher water dripping through two floors of their neighbor’s ceiling.

Ready? Next, let’s see if the 100 Series makes sense for you.

Bosch 100 Series: Good Entry, Few Frills

The Bosch 100 Series is your budget-friendly ticket into the Bosch lineup. It’s great if you want a trusted name without dropping four figures.

Just know you’re trading off some of the classic Bosch performance and quietness for that lower price tag.

Bosch 100 Series Key Features:

• Tub: Stainless steel sides with a plastic bottom. Stainless helps with heat and odor control. Plastic is fine but can hold smells over time.
• Noise Level: Runs at 46–50 decibels. For reference, 44 dB is the “quiet” sweet spot, so you’ll hear this one running if your kitchen opens to your living space.
• Cycles: You’ll get the basics: AutoWash (senses how dirty your dishes are), Normal, QuickWash, PowerScrub for baked-on messes, plus Eco mode to save water and power.
• Racking: Standard racks with basic adjustability. No RackMatic yet. Fitting tall pots might mean a little juggling.
• Drying: Uses condensation drying, which is just the heat and steam from the wash, a rinse aid like JetDry, and time. Works well on plates and glasses, but plastic lids might come out damp.
• Leak Protection: 24/7 overflow protection. Not fancy, but it does the job.
• Price Range: Expect $549–$699, depending on the style and handle.

What’s the Difference?

You’ll see the 100 split into Standard, 100 Plus, and 100 Premium. It’s pretty simple:

• Standard: Basic controls, lightest door.
• Plus: Slightly quieter (around 46 dB vs. 50 dB) and sometimes upgraded racks.
• Premium: A bit more sound insulation and minor style tweaks, including better handle finishes and a quieter door.

Performance is nearly the same. The upgrades are small improvements in noise and style.

Who It’s For:

If you’re updating a rental unit, outfitting a small Boston condo, or adding a second dishwasher for a basement bar or in-law suite, the 100 Series works.

It’s Bosch in name but without the classic Bosch quietness or drying power of the higher series.

💡Pro Tip: A quick cycle with a dishwasher cleaner—or even a splash of Tang—keeps that plastic base from picking up funky smells.

Other Dishwashers to Consider

• If you want something in the same price range, check LG for top reliability and steam cleaning.
• KitchenAid is another option if you prefer an American brand with a built-in heating element for drying.

Both are good choices but may run louder than Bosch.

Bosch 300 Series: The First Real Bosch

If the 100 Series is your starter model, the Bosch 300 Series is where you really see what Bosch is known for.

Expect a quieter wash, an all‑stainless tub, better racks, and more flexibility for real‑life cooking messes.

Bosch 300 Series Key Features:

• Tub: Fully stainless steel. It holds heat better, dries better, and won’t trap odors like plastic can.
• Noise Level: 46 decibels. Not silent, but noticeably quieter than the 100 Series. You’ll hear a soft hum, not a kitchen roar.
• Cycles: Adds more options, including Auto, Normal, Heavy, Express, Sanitize for baby bottles or cutting boards, and an Eco mode for lower energy use.
• Racking: The RackMatic system shows up here. This is Bosch’s adjustable upper rack that lets you raise or lower it to fit taller pots below or big wine glasses above. You also get a third rack for silverware, freeing up space on the bottom.
• Drying: Still uses condensation drying with heat, steam, JetDry, and time. You’ll see the same mild struggle with plastic lids.
• Leak Protection: Upgraded to AquaStop, a sensor system that shuts off the water if there’s a leak.
• Price Range: Typically $899 to $1,019, depending on finish.

Who It’s For:

The 300 is popular everywhere, from city condos to Cape remodels, because it’s the first classic Bosch. It’s fully stainless inside with RackMatic racks that make life easier.

💡Pro Tip: If you’re always washing wine glasses or oversized pans, you’ll appreciate the third rack and RackMatic adjustability more than you think.

Similar Dishwashers to Consider

• LG LDTH7972S ($999): This LG dishwasher uses steam to loosen tough stains and help dry glasses.

Bosch 500 Series: The Sweet Spot for Quiet and Drying

The Bosch 500 Series has been Yale’s most popular dishwasher line for years, and for good reason.

It’s noticeably quieter, has a better drying system, and keeps all the practical Bosch upgrades you want without jumping into luxury pricing.

Bosch 500 Series Key Features:

• Tub: Fully stainless steel, top to bottom. It offers better heat retention and helps with drying.
• Noise Level: 44 decibels. This is the sweet spot where you barely hear it running, even if your kitchen is open to your living room.
• Cycles: Builds on the 300 with more flexibility. Includes Auto, Heavy, Normal, Express, Delicate (gentler for fine dishes), Half Load for small runs, and Favorites so you can save your go-to settings.
• Racking: RackMatic adjustable upper rack, plus a handy third rack for silverware or spatulas.
• Drying: Adds AutoOpen Door. The door pops open slightly at the end of the cycle to release steam and reduce moisture clinging to your dishes. This helps plastics dry better than condensation alone.
• Leak Protection: AquaStop with smart leak sensors that shut off water if there’s a problem.
• Price Range: Usually $1,099 to $1,149, depending on handle style and finish.

Who It’s For:

If you cook a lot, love entertaining, or have an open-concept kitchen where noise matters, the 500 hits the sweet spot.

It’s quiet enough for your dinner party and dries better than the basic Bosch models without stepping up to the premium price tag.

Local Note: This dishwasher is popular everywhere from Wellesley to Wareham to Westerly. It’s quiet, reliable, and works day in and day out for families who run it every night.

💡Pro Tip: Run it at night. The AutoOpen pops the door, so your dishes are dry and ready for coffee mugs in the morning.

Similar Dishwashers to Consider

• Miele's G 5000 series has three full wash arms, plus their drying lets air inside the dishwasher. The colder air mixes with, the steamier air and is dissipated as water.
• KitchenAid's M series dishwashers have four-level wash action and large top racks.

Bosch 800 Series: Top Silence Ratingand Best Drying System

The Bosch 800 Series is where Bosch shows off its best everyday tricks.

It runs nearly silent, tackles stuck-on messes with its PowerControl spray arm, and finally dries your plastics so you’re not stuck wiping lids at midnight.

Bosch 800 Series Key Features:

• Tub: All stainless steel inside. Holds heat well and doesn’t trap odors.
• Noise Level: 42 decibels. So quiet you might open it by mistake while it’s still running.
• Cycles: Auto, Heavy, Normal, Express, Delicate, Half Load, Extra Dry, and the new PowerControl option for extra scrubbing power where you need it.
• PowerControl: The upgraded spray arm lets you boost water pressure in just part of the lower rack. That way, you can blast stuck-on casserole messes without over-spraying delicate dishes.
• Racking: RackMatic upper rack adjusts up or down to make room for tall items. The MyWay third rack is deeper than the standard version, so you can stack mugs and bowls, not just silverware.
• Drying: CrystalDry uses Zeolite, a natural volcanic mineral that absorbs moisture and releases heat to help dry even the trickiest plastic lids and containers.
• Leak Protection: AquaStop sensors shut off water if they detect a leak, so you don’t wake up to a puddle in your Seaport condo.
• Price Range: Usually around $1,349 to $1,499, depending on style and panel options.

Who It’s For:

This series is for anyone who’s done toweling off plastics.

It delivers premium quiet, smart cleaning zones, and Bosch’s best drying without the step up to Benchmark pricing.

💡Pro Tip: Use the app to dial up PowerControl for stuck-on pans and keep your wine glasses spotless in the same load.

One Thing to Know About PowerControl

• Available on: Bosch 800 and Benchmark Series only
• What it does: Boosts spray pressure on a specific zone of the lower rack to knock off stuck‑on food while sparing delicate glasses.
• How to use it:
  1. Connect the dishwasher to Wi‑Fi.
  2. Install the Bosch HomeConnect app.
  3. Select PowerControl from your phone before starting the cycle.

❗Important: There’s no physical button for PowerControl. No app = no PowerControl.

Similar Dishwashers to Consider

• If you’re shopping near the 800 Series price, Miele’s Crystal Series competes on drying performance and build quality.
• LG’s top models offer steam, fast cycles, and strong reliability.
• SKS, LG’s luxury spin-off, is an option if you want something unique with a one-hour wash and dry promise.

Just be sure service is easy to get where you live.

Bosch Benchmark Series: Smoother Feel, Premium Touches

The Bosch Benchmark Series keeps everything you get in the 800 Series: an all‑stainless tub, CrystalDry for better plastic drying, a full cycle roster, PowerControl zone cleaning, and AquaStop leak protection.

It also adds smoother ball‑bearing racks, interior lights, and a more refined finish.

Bosch Benchmark Key Features

• Tub: Full stainless steel for better heat retention and odor control.

💡 Pro Tip: Visit a showroom and slide the Benchmark racks yourself; the upgraded feel is obvious within seconds.

Which Bosch Dishwasher Should You Buy?

Quick Answer: Buy the Bosch series that matches your lifestyle: 100 for budget basics, 300 for essentials, 500 for quiet drying, 800 for premium performance, and Benchmark for a luxury feel.

Bosch dishwashers run quiet, clean well, and if you choose the right one, your plastic containers will come out dry without you wiping them at midnight.

Here’s the quick recap:

• 100 Series: A good entry if you want the Bosch name at the lowest price. Works fine for rentals or second kitchens, but you give up the classic Bosch quietness and better racks.
• 300 Series: The first true Bosch feel with an all-stainless tub and the RackMatic adjustable rack. Quieter than the 100 and popular for busy families and everyday cooks.
• 500 Series: The sweet spot for most people. Quiet enough for an open kitchen with improved drying thanks to AutoOpen.
• 800 Series: Quieter still, with PowerControl cleaning zones, CrystalDry to dry plastics properly, and the deeper MyWay third rack for mugs and bowls. The best all-around performance without paying the Benchmark premium.
• Benchmark: Same cleaning, drying, and quietness as the 800. The difference is smoother, premium racks with ball-bearing rails, interior lights, and a slightly upgraded finish. It’s for buyers who want the best feel and polish Bosch offers.

If you want to skip the rewashing, enjoy a quiet run, and hate toweling off plastic lids every night, Bosch is worth a look.

Just match the series to how you cook and how much noise you want to hear.
