How to Get Your Dishes to Dry in Your Bosch 300 Dishwasher

According to Consumer Reports and the NY Times Circuit Breaker, the best dishwashers in 2021 are, in order:

  • Bosch 300 SHEM63W55N
  • Maytag MDB7959SKZ (CR reports as Whirlpool)
  • Miele Classic Plus G4229SCUSS

So naturally when our 16-year-old Kenmore called it quits we got the Bosch. After getting used to all of the features and settings I do like this unit more overall. The third drawer is great for misc kitchen utensils, the dishes do get cleaner than they ever did in the old one, the lack of heating element means that plastics can go in any tray, and I love having a front-facing timer that tells me when the wash will be finished.

But all the rumors and complaints you’ve heard about it not being able to dry dishes are true. It will not dry your dishes.

According to Bosch’s website, their units are sealed (not vented) by design:

All Bosch dishwashers use a condensation drying process…which is more hygenic…

  • The final rinse uses high-temperature water to make the dishes very hot.
  • The stainless steel tub of the dishwasher cools faster than your dishes because stainless steel cools faster than glass and porcelain.
  • Condensation occurs when the moist air in the dishwasher comes into contact with the cooler stainless steel tub, and turns into water droplets. These water droplets trickle down to the bottom of the dishwashers and are drained.

Problem is, there is a limit to how much steam the tub is going to absorb, and even if you use the “extra dry” cycle, you still end up with dishes that are wet to the touch.

You can visually see water left on plastic after “drying” overnight. Significant condensation still exists on the stainless steel interior walls

Almost as an admission of guilt, the Bosch 500 and 800 series dishwashers have a feature called “autoair” which automatically pops the door open after a cycle completes, allowing the steam to escape and dry both your dishes as well as the interior of the machine.

So as a solution to this problem I present to you the DRYINATOR!


I made this using some random lego bricks I had lying around and you can, too. As you can see from the below photos, this slides right over the top of your door and does manually what the expensive models do automatically!

    This does not make sence to me. If the washer is not closed properly it does not start. I don’t have an auto dry on my washer, and I don’t have Legos. I am very disappointed in this washer

  2. Hey Lee,

    We both agree that Bosch has made a mistake by designing a sealed dishwasher. My article simply details a workaround in which you and I need to wedge something (doesn’t have to be legos) to keep the door open AFTER the dishwashing cycle is over so it can air out. It’s a pain but in the end the dishes probably do get more dry than they would with a vented model. ¯\_(ツ)_/¯
