  1. Condensation Dry: Uses the physics of condensation to pull moisture off dishes.
  2. Fan-Assisted Dry: #1, plus air circulation to help things along.
  3. Heated Dry: Add a separate heating element to heat the air so moisture evaporates off dishes.

That's where a dishwasher's heat setting comes into play. Dishwashers dry dishes in several ways: with an electric coil that heats the air, a fan that blows hot air around, an increase in water temperature near the end of a cycle—or a combination of all these methods.Sep 7, 2020

Why do Bosch dishwashers not dry?

Overcrowding is one of the most common reasons your Bosch dishwasher leaves dishes wet. When cups and plates are placed too close together there is little room for hot air to flow and sufficiently dry each item.

Why are dishes still wet after dishwasher cycle?

What happens is that opening the dishwasher allows a burst of cooler air to enter. When met with the hot air inside, this causes steam and that will re-condensate. This condensation will land on your dishes and is likely to stay there even after the dry cycle is done. This is not a problem that needs to be repaired.

Why having a dishwasher that dries dishes matters

While it may seem kind of silly to harp on about how dishwashers dry a plate when you can wipe it down with a cloth—although not just as easily—there are some really practical reasons why you should pay attention to how well your dishwasher dries dishes—especially when it comes time to buy a new one.

Method 1: Evaporation

Certain Miele dishwashers pop open automatically after a cycle finishes, allowing moisture to escape.

Method 2: Electric heating element

Most entry-level dishwashers use a metal coil that produces heat to dry dishes.

Method 3: Heated air dry

Higher-end GE dishwashers like the Cafe CDT875M5NS5 use a series of fans to dry dishes.

How a Dishwasher Works on the Inside

There are three elements to dishwashing that make it so effective at leaving dishes bright and shiny. Dishwashers combine detergent, wash systems and heat to help your dishes come out clean. For a heavy-duty clean that adds steam, check out the PowerBlast ® cycle by Maytag brand.

Detergent

An important component is the detergent that will be dispensed during the cycle. A combination of chemicals that help remove food particles and residue, detergent also typically includes water-softeners, anti-corrosion chemicals and enzymes that help boost wash performance. The detergent will dispense at the optimized time.

Wash System

During a wash cycle, your dishwasher’s pump will force water into the water jets. Multiple spray arms will rotate as they blast water throughout the tub to remove food particles from dishes. As the food washes away, particles are trapped in a filter.

Heat

Another element that also plays a large role during a dishwasher cycle is heat. Your dishwasher has a heating element that is usually located at the base of the tub. This heating element heats up the water, which can reach temperatures upwards of 155ºF–hotter than the hot water from the faucet.
