Dishwasher Not Draining? Potential Causes and Fixes

Dishwasher Not Draining? Potential Causes and Fixes

Introduction

Are you tired of dealing with a dishwasher that doesn't drain properly? It can be frustrating to finish a load of dishes only to find that there is still standing water at the bottom of the machine. Not only does this leave your dishes dirty, but it can also lead to unpleasant odors and potential damage to your dishwasher. In this article, we will explore the potential causes of a dishwasher not draining and provide you with some possible fixes. So, let's dive in and get your dishwasher back in working order!

Common Causes of a Dishwasher Not Draining

Clogged Drain Hose

One of the most common causes of a dishwasher not draining is a clogged drain hose. Over time, food particles, grease, and detergent residue can build up in the hose, obstructing the flow of water. This can prevent the dishwasher from draining properly. To fix this issue, you will need to remove the drain hose and clean it thoroughly.

Blocked Air Gap

Another possible cause of a dishwasher not draining is a blocked air gap. The air gap is a small device located on top of the sink or countertop near the dishwasher. Its purpose is to prevent wastewater from flowing back into the dishwasher. However, if it becomes blocked with debris, it can hinder proper drainage. Cleaning the air gap should resolve this issue.

Faulty Drain Pump

If neither the drain hose nor the air gap is causing the problem, it could be due to a faulty drain pump. The drain pump is responsible for removing water from the dishwasher during the draining cycle. If it becomes damaged or appliance repair service in Gresham, OR worn out, it may not be able to effectively pump out the water. In this case, replacing the drain pump may be necessary.

Clogged Filter

A clogged filter can also lead to a dishwasher not draining properly. The filter is designed to catch food particles and debris, preventing them from clogging the drain hose or pump. However, if the filter becomes clogged itself, it can impede water flow and cause drainage issues. Cleaning or replacing the filter should resolve this problem.

Faulty Float Switch

The float switch is a small device located at the base of the dishwasher. It is responsible for detecting the water level inside the machine. If the float switch becomes stuck or faulty, it may not signal the dishwasher to stop filling with water, resulting in an overflow and poor drainage. Replacing the float switch should fix this issue.

Clogged Garbage Disposal

If your dishwasher is connected to a garbage disposal, a clog in the disposal can also lead to drainage problems. When you run your garbage disposal, food scraps can accumulate and create blockages that prevent proper water flow from the dishwasher. Clearing any clogs in the garbage disposal should help resolve this issue.
