Understanding the Importance of the Lower Door Seal

The lower door seal, also known as the gasket, plays a crucial role in your Bosch dishwasher’s functionality. It forms a tight seal between the door and the tub, preventing water from escaping and ensuring proper cleaning. Over time, the seal can become worn, cracked, or damaged, leading to leaks.

Identifying the Need for a Replacement

Before diving into the replacement process, it’s essential to confirm whether your lower door seal needs replacing. Here are some telltale signs:

• Visible cracks or tears: Inspect the seal for any signs of damage.
• Water leaking from the bottom of the door: This is a clear indication of a faulty seal.
• Difficulty closing the door: A worn seal can make it harder to close the door properly.
• Mold or mildew around the door: This indicates a persistent leak and a need for replacement.
