“New Dishwasher Wet Inside” refers to a common issue experienced by some dishwasher owners, where the interior of their newly purchased dishwasher retains excessive moisture even after completing a washing cycle. This problem can be perplexing and frustrating, as dishwashers are expected to leave dishes dry and ready to use. The issue can stem from various factors, including incorrect settings, valve problems, or even potential leaks within the dishwasher.

To address the “New Dishwasher Wet Inside” problem effectively, it’s essential to follow a systematic approach to identify and rectify the underlying cause. This typically involves checking the dishwasher’s settings, inspecting components such as the water inlet valve, float switch, and drain system, and ensuring proper ventilation. Moreover, leaving the dishwasher door open after use can help prevent mold growth and allow excess moisture to dissipate.

The Quick Answer

Your dishwasher may always be wet inside due to various reasons, including incorrect settings, valve problems, and even potential leaks. Here’s a step-by-step guide to help you tackle the issue:

Step 1: Check Your Settings

Before diving into any complicated troubleshooting, make sure you’re not unintentionally causing the issue:

Step 2: Investigate Dry Cycle Settings

Take a closer look at your dishwasher’s settings:

  • Manual Dry Cycle: Some dishwashers require you to manually select the dry cycle. Check the front panel buttons to see if this might be the culprit.
  • Wash Cycle Selection: Ensure that you haven’t accidentally chosen a wash cycle that primarily rinses without proper drying. Double-check your chosen cycle for its drying capabilities.

Step 3: Examine the Water Inlet Valve

A malfunctioning water inlet valve could be the root cause of excessive moisture:

  • Valve Issues: Investigate if the water inlet valve is stuck open. This could lead to an overabundance of water inside the dishwasher, resulting in excessive wetness.

Step 4: Timing Matters

Consider the timing of your dishwasher activities:

Step 5: Garbage Disposal Inspection

Look into the garbage disposal:

  • Leakage Concerns: Check for any signs of dirty water coming from the garbage disposal. If you detect this, it could indicate a valve issue. In such cases, contemplate replacing the valve responsible for controlling grimy water flow.

Step 6: Clear Blockages

Don’t overlook potential blockages:

  • Food Debris: Examine the dishwasher’s components, such as valves, hoses, or drains, for any food debris or blockages. These obstructions can lead to water retention.

Step 7: Address Leaks

If all else fails, consider the possibility of leaks:

  • Hose Sealing: Your dishwasher might have a water leak due to an improperly sealed hose. Locating and rectifying the leak is essential to prevent further moisture accumulation.

Step 8: Ventilation Check

Ensure the dishwasher’s ventilation system is unobstructed:

  • Vent Opening: Confirm that the dishwasher’s vent, responsible for releasing hot steam, isn’t blocked by stickers or other obstructions. Adequate ventilation helps prevent excess moisture.

Step 9: Steam Feature

In some cases, a malfunctioning steam feature can contribute to excess moisture:

  • Steam Function: If your dishwasher boasts a steam feature for better sterilization, check if it’s running excessively due to a malfunction. Troubleshoot or turn off this feature if needed.

Step 10: Sani-Rinse Cycle

Consider switching to an alternative cycle:

The Unboxing Experience

Upon receiving your new replacement dishwasher, you may notice excessive moisture inside the machine and perhaps even a strange smell. This can be concerning, especially if you’ve invested in a new appliance. Here’s what you can do:

  • Open the Door: When you unbox your new dishwasher, don’t be surprised to find it slightly damp inside. It’s common for manufacturers to test the machine with water before shipping it out.
  • Smell: If you detect a peculiar odor, it’s not uncommon. New appliances may have a factory smell that can dissipate over time. Leaving the door open, as per the instructions, can help with ventilation.
  • Mold Prevention: To prevent mold growth, ensure you leave the dishwasher door open as recommended. Mold can develop in hidden areas, so proper ventilation is crucial.

Should a New Dishwasher be Wet Inside

Bosch offers three different drying technologies in their dishwashers:

  1. Pure Dry: This is an energy-efficient clothes drying system designed to remove moisture from the dishes as they cool, without pulling in outside air.
  2. Auto Air: This drying technology automatically opens the dishwasher door when the cycle is complete to circulate fresh air, resulting in dishes that are 40% drier.
  3. Crystal Dry: This patented technology is available in Bosch’s premium series dishwashers (800, 800 premium, and select benchmark series). Crystal Dry transforms moisture into heat, leaving dishes 60% drier, even plastics.

Some tips for enhancing the drying process in a dishwasher:

  • Avoid pre-washing dishes as it can make it harder for detergent to do its job.
  • Load dishes at an angle to encourage water to run off naturally, preventing pooling and dripping.
  • Consider using a rinse aid like Jet Dry to reduce surface tension, allowing water to run off more freely for even drier dishes and to prevent water spots.
  • When unloading the dishwasher, start with the bottom rack and work your way up to prevent water from the top racks from dripping down onto the lower rack dishes.


Experiencing a constantly wet interior in your new dishwasher can be frustrating, but it’s a manageable issue with the right approach. By following these steps and considering the unboxing experience, you can enjoy clean, dry dishes and a hassle-free dishwasher.
