Why Is My New Bosch Dishwasher Wet Inside

In the world of modern appliances, Bosch is a name that commands trust and excellence. So, when you invest in a brand-new Bosch dishwasher, you expect nothing less than perfection. However, if you’ve noticed that your new Bosch dishwasher is wet inside after a cycle, you might be wondering what’s going on. In this article, we’ll dive into the perplexing issue of a wet interior in your Bosch dishwasher, exploring the possible reasons behind it, and how to address this concern effectively.

Understanding the Basics

Before we delve into the reasons behind the wet interior of your Bosch dishwasher, let’s start with some essential information about how dishwashers work. Understanding the basic mechanics will help you grasp the root causes of the issue.

The Dishwashing Process

When you initiate a dishwasher cycle, it goes through several stages, including:


  • The dishwasher pre-rinses your dishes to remove loose food particles.

Main Wash

  • Detergent and hot water are used to clean and sanitize your dishes.


  • Clean water is sprayed to remove detergent and residue from your dishes.

The Drying Process

After the cleaning process, the dishwasher begins the drying phase. This is where things get interesting, and sometimes, confusing.

Common Reasons for a Wet Interior

Now, let’s explore why your new Bosch dishwasher may have a wet interior.


One of the most common reasons for moisture inside your dishwasher is condensation. This occurs when the hot water used during the wash and rinse cycles meets the cooler interior surfaces of the dishwasher, causing water vapor to form.

How to Address Condensation

  • Ensure your dishwasher is properly insulated.
  • Use a rinse aid to help water sheet off the dishes.

Dishwasher Design

Bosch dishwashers are known for their energy-efficient designs. This efficiency can sometimes result in residual moisture being trapped inside the dishwasher after the cycle is complete.

How to Address Design-Related Moisture

  • Allow the dishwasher door to remain slightly ajar after a cycle to let the moisture evaporate.
  • Use a towel to wipe down the interior if necessary.


Overloading your dishwasher can obstruct proper air circulation, leading to moisture retention.

How to Address Overloading

  • Follow the manufacturer’s guidelines for loading dishes.
  • Leave space between dishes for air to flow.

Faulty Gasket or Seal

A damaged door gasket or seal can allow moisture to escape, leaving the interior wet.

How to Address Gasket or Seal Issues

  • Inspect the gasket for any visible damage and replace it if necessary.
  • Ensure the door latches securely when closed.


Having a wet interior in your new Bosch dishwasher may be perplexing, but it’s often a result of normal dishwasher processes like condensation and energy-efficient designs. By understanding these factors and following the suggested solutions, you can enjoy spotless dishes and a dryer interior.
