  • Great cleaning performance

  • Great features


  • Too expensive for what it offers

  • Confusing controls

While it doesn't boast the same sleek look we tend to expect from Bosch, the SHEM3AY52N removes an above-average amount of stains without making a racket. If you’re looking above-average stain removal without all the flashy features, this is the one to get.

The front-facing controls allow you to always know how much longer the cycle will last.

What we like

Cleans off plates: The SHEM3AY52N is a dishwasher that lives up to its name. Cycle after cycle, it got our testing plates 97.7 percent clean. That’s a strong showing, especially at the sub-$500 price point. However, this isn't the best showing Bosch has ever had. The 800 Series can get plates to 99.94 percent clean. However, the 800 series is the best of what Bosch has to offer.

The Bosch SHEM3AY52N is quiet enough to have a conversation in front of it.

Quiet Operation: This Bosch operates at around 50 dBA. To put that in perspective, 50 dBA is about as loud as a rain pattering against a glass window. More to the point, it’s unlikely you’ll be able to hear your dishwasher from another room while it’s running.

Cupboard-ready dishes: It’s a little hidden (you have to hit Delicates and Start at the same time, then Heavy or Rinse), but you can actually increase the temperature of the final rinse. Hot water is more apt to evaporate off dishes, so with the right settings you can bone-dry plates after every cycle.

Bsoch SHEM3AY52N Utility Rack

The Utility Rack acts like a small third rack.

A third rack... sort of: The SHEM3AY52N has a sort of pseudo-third rack. On the left-hand side of the upper cavity, there’s an area called the Utility Rack where you can place a ladle or a set of knives. When not in use, the rack has hinges that allow it to make room for taller items. It's not as useful as a full third rack, but we're not complaining about the extra space.

Stainless steel interior: Like the third rack, this 100-Series dishwasher has a stainless steel tub, of a kind. Five of the six sides are made of stainless steel while the bottom is made of durable plastic. Having metal on most of the sides helps dampen down noise, and the plastic bottom helps lower costs. It’s not as great as having steel on all sides, but it still provides that classic look.

What we don't like

Bosch-SHEM3AY52N Secret Menus

You can control the amount of rinse aid used and how hot the final rinse is.

It's not a looker: Bosch is better known for bringing European elegance into the kitchen. The SHEM3AY52N isn't going to do that. It has a white plastic exterior and clunky front-facing buttons. The display looks like it belongs to a department store alarm clock. At this lower price point, you can usually get stainless on the outside or the inside, but not both. Bosch chose to hide all the beauty on the inside for this model.

Too many secret menus: In an effort to have a simple design, Bosch hid most of the features behind complicated controls. All the buttons on the control panel serve a dual purpose. However, you’d never know without studying the manual. For example, if you hit Delicates and Start at the same time, then hit Delicates again, then hit either Heavy or Rinse, you can adjust how much rinse aid you use. It’s all a bit much.

Not the best cleaner for the money: While the Bosch SHEM3AY52N showed us some impressive cleaning scores, it isn’t the best in its price range. The Whirlpool WDT730PAHZ costs around the same and removed 2 percent more stains. That might not sound like a lot, but at this price point, it’s a war of inches.

What users are saying

Averaging the ratings at Home Depot, Lowes, AJ Madison, and Best Buy, users gave the Bosch SHEM3AY52N 4.3 out of 5 stars. They cite how much they appreciate the build quality and quiet operation. Detractors say they dislike how cluttered the upper rack is.

Should you buy this dishwasher?

Save for a major sale or snatching up a discontinued model, this is the most affordable Bosch dishwasher you can get. The brand has a stellar reputation for a reason. The SHEM3AY52N outshines most dishwashers in this price range. It cleans well and has a lot of unique features like the Utility Rack and an adjustable rinse aid dispenser. For those willing to read the manual, this Bosch has much to offer.
