Dishwasher Leaking From The Bottom

Not every home relies on a dishwasher to manage the ongoing task of cleaning dishes, but those who have one can understand that these handy kitchen appliances save a lot of time.

However, dishwashers can sometimes develop leaks, causing water to seep, drip, or pour out from the bottom, potentially increasing water bills by 10% or causing water damage at home. If this happens, it’s important to inspect the dishwasher and troubleshoot the issue to identify the cause of the leak.

Some dishwashers have built-in indicators or error codes that alert you to leaks even if you don’t see any water, helping you to address the problem before it worsens if the purpose of this content from our experts at Anderson Restoration.

Common Leaking Dishwasher Causes

Faulty Gasket

A faulty gasket is one of the most common reasons for a dishwasher leaking from the bottom. The gasket is the rubber seal around the door that ensures water stays inside during the wash cycle. Over time, this gasket can wear out, crack, or become damaged, leading to leaks.

Broken Water Pump System

The water pump system is responsible for circulating water throughout the dishwasher during the wash cycle. If this system is broken, it can cause leaks from the bottom of the appliance.

Clogged Filter

A clogged filter can also cause a dishwasher to leak from the bottom. When the filter is blocked, it can prevent water from draining properly, leading to overflow and leaks.

Damaged Water Inlet Valve

The water inlet valve controls the flow of water into the dishwasher. If this valve is damaged or malfunctioning, it can cause water to leak from the bottom of the appliance.

Defective Float Switch

The float switch monitors the water level inside the dishwasher and prevents it from overfilling. A defective float switch can cause the dishwasher to overflow and leak from the bottom.

How Can Water Damage From Leaking Dishwasher Affect Your Home?

Water damage caused by a leaking dishwasher can result in several issues, both immediately and over time. The extent of the damage depends on factors like the duration of the leak, the amount of water, and the affected materials. Here are some common consequences:

Structural Damage:

Water can seep into various types of flooring, including hardwood, laminate, and tile. This can cause warping, buckling, or loosening of the flooring material. Persistent leaks can penetrate the subfloor, leading to rot, mold, and structural weakening. This can necessitate extensive repairs or replacement.

Cabinetry and Furniture Damage:

Cabinets surrounding the dishwasher can absorb water, leading to swelling, warping, and deterioration of the material. Any furniture or wooden items near the leak can also be affected, potentially causing warping and weakening.

Mold and Mildew Growth:

Mold and mildew thrive in damp environments. Their growth can pose health risks, particularly respiratory issues and allergies. Mold can spread to other areas, damaging walls, insulation, and other structural elements.

Appliance and Electrical Hazards:

The dishwasher itself might suffer damage if internal components are exposed to water. Water can come into contact with electrical outlets or wiring, creating a risk of electrical shorts or fire hazards.

Aesthetic Damage:

Water can cause staining and discoloration on floors, walls, and cabinetry. Moisture can lead to peeling paint or wallpaper in the affected areas.

How to Fix a Leaking Dishwasher?

Fixing a leaking dishwasher typically involves several steps, but keep in mind that the exact process may vary depending on the specific issue. Here is a general step-by-step guide:

  • Turn Off the Power and Water Supply: Before starting any dishwasher seal replacement, ensure the dishwasher is unplugged and the water supply is turned off to prevent any accidents.
  • Inspect the Door Gasket: Check the rubber seal around the dishwasher door for any signs of wear, cracks, or damage. If the gasket is faulty, replace it with a new one by removing the old gasket, cleaning the area, and installing the new seal according to the manufacturer’s instructions.
  • Check the Water Pump System: Look for any visible damage or wear in the water pump system. If the pump is broken, purchase a replacement and follow the manufacturer’s instructions for installation. While replacing the dishwasher seal, ensure it is properly fitted to prevent future leaks.
  • Clean the Filter: Remove the dishwasher filter and rinse it under running water to clear any debris. If the filter is heavily clogged, soak it in warm, soapy water before rinsing. Reinstall the filter once it’s clean and ensure it is securely in place.
  • Examine the Water Inlet Valve: Inspect the water inlet valve for cracks or damage. If you find any issues, replace the valve by purchasing a new one and following the manufacturer’s installation guide.
  • Test the Float Switch: Check the float switch for proper operation. If the switch is defective, replace it by purchasing a new one and following the manufacturer’s instructions for installation.
  • Run a Test Cycle: After completing the repairs, run a test cycle to ensure the dishwasher is no longer leaking.

How Do I Know It's Time To Replace My Dishwasher?

If your dishwasher is over 10 years old, it might be more cost-effective to replace it rather than continuing to repair it. Newer models are typically more energy-efficient and reliable. Dishwashers often start to leak once they reach around 10 years of age, and any type or brand can experience leakage, especially as they get older. If you’re frequently calling a repair technician or constantly dealing with breakdowns, it might make more sense to invest in a new dishwasher.

Cracks or other damage to the interior tub can lead to leaks and further damage to your kitchen. This is often an expensive repair that might warrant a replacement. Modern dishwashers come with advanced features like smart technology, improved energy efficiency, and better cleaning cycles. If your old dishwasher lacks these features, upgrading might improve your kitchen’s functionality.
