Why Is My Dishwasher Leaking Water? Causes & Solutions for Dishwasher Leaks

A dishwasher leaking water can be more than just a minor inconvenience. It often signifies underlying issues that need prompt attention. This comprehensive guide is designed to help you understand, diagnose, and resolve common problems associated with dishwasher leaks, ensuring the longevity and efficiency of your appliance.

⚠️ DO NOT attempt to fix a leaking dishwasher on your own unless you have the technical expertise. A leaking dishwasher can result in serious damage to your floors and walls. Please contact Cody’s Appliance Repair for assistance if you are uncertain how to proceed.

How to Troubleshoot and Prevent Dishwasher Leaks

The inconvenience of a leaking dishwasher is not just about the mess; it can also lead to significant water damage. Understanding the common causes of these leaks is the first step in prevention and repair.

Improper Detergent Use

Using too much detergent, or the incorrect type, is a frequent mistake leading to dishwasher leaks. Unlike hand dishwashing soap, dishwasher detergents are specifically formulated to minimize suds. When regular dish soap is used, it creates excessive foam, which can push against the door seal, causing leaks.

Ideal Detergent Usage:

  • Type: Always use a detergent specifically designed for automatic dishwashers.
  • Amount: Follow the manufacturer’s recommendation. Using too much detergent not only causes leaks but can leave residue on dishes.
  • Water Hardness: Consider your water hardness. Softer water requires less detergent, as it forms suds more easily.

Clogged Dishwasher Drain

A clogged dishwasher drain is a common source of leaks. Over time, food particles, grease, and soap residue can accumulate in the dishwasher filter and drain, leading to blockages.

Preventing and Clearing Clogs:

  • Regular Cleaning: Clean the filter and drain area regularly to prevent buildup.
  • Clearing Blockages: If you suspect a clog, disconnect the dishwasher from power, remove the bottom rack, and unscrew the drain filters. Clean them thoroughly and use a non-abrasive tool to gently dislodge any blockages.
  • Vinegar and Baking Soda: A natural cleaning solution of vinegar and baking soda can help dissolve grease and clear minor clogs.

Damaged Dishwasher Door Gasket

The dishwasher door gasket, or seal, is crucial in preventing water from escaping. Over time, it can become worn, cracked, or lose its elasticity, leading to leaks.

Inspecting and Replacing the Gasket:

  • Regular Inspection: Check the gasket regularly for signs of wear or damage.
  • Cleaning: Clean the gasket with a damp cloth to remove any debris that might prevent a proper seal.
  • Replacement: If the gasket is damaged, it can often be replaced without professional help. Gently pull out the old gasket and press the new one into place, ensuring it is seated correctly.

Dishwasher Air Gap Obstruction

The air gap is a small cylinder on the top of the sink, near the faucet. It prevents contaminated water from siphoning back into the dishwasher. If obstructed, it can cause water to back up and leak out.

Maintaining the Air Gap:

  • Understand the Air Gap: The air gap is connected to the dishwasher’s drain hose and ensures that dirty water doesn’t flow back into the dishwasher or your clean water supply.
  • Regular Checks: Inspect the air gap regularly. Remove the cover and check for debris or buildup that could obstruct the flow of water.
  • Clearing Obstructions: If you find any obstruction, clean it thoroughly. Ensure that both the air gap and the hose leading to the garbage disposal or sink drain are clear.
  • Professional Inspection: If you’re unsure how to check or clear the air gap, it might be wise to call a professional, as improper handling could lead to more significant issues.
