Step-by-Step Guide: How to Replace KitchenAid Dishwasher Diverter Motor

Are you tired of your KitchenAid dishwasher struggling to drain properly? A faulty diverter motor could be the culprit. This vital component controls the water flow between the wash and rinse cycles, ensuring your dishes get clean. When it malfunctions, your dishwasher might not drain at all, leading to a soggy mess. Replacing the diverter motor is a common repair that can be tackled by DIY enthusiasts with some basic tools and a little patience.
This guide will walk you through the process of replacing your KitchenAid dishwasher diverter motor step-by-step, providing detailed instructions and helpful tips along the way.

Understanding the Dishwasher Diverter Motor

The diverter motor is a small but essential component located within your dishwasher. It’s responsible for directing the water flow between the wash and rinse cycles. When the motor fails, water may not be able to drain properly, causing a range of issues:

• Standing water in the tub: The most common symptom of a faulty diverter motor is water remaining in the dishwasher after the cycle ends.
• Noisy operation: A malfunctioning diverter motor can create grinding or rattling noises during operation.
• Leaking: A broken diverter motor can lead to leaks as water spills from the dishwasher.

Identifying the Problem: Is It Really the Diverter Motor?

Before diving into the replacement process, it’s crucial to confirm that the diverter motor is indeed the culprit. Here are some troubleshooting steps to help you pinpoint the issue:
1. Check the drain hose: Ensure the drain hose is not kinked, blocked, or disconnected.
2. Inspect the drain filter: A clogged drain filter can also prevent water from draining properly.
3. Run a test cycle: Observe the dishwasher’s operation during a cycle. If the water doesn‘t drain properly, it’s likely a motor issue.

Gathering the Necessary Tools and Materials

Before you start, gather the following tools and materials:

• New diverter motor: Ensure you purchase the correct replacement motor for your KitchenAid dishwasher model.
• Phillips screwdriver: For removing screws and securing the new motor.
• Flathead screwdriver: For prying off panels and accessing the motor.
• Adjustable wrench: For loosening and tightening nuts.
• Safety glasses: To protect your eyes from debris.
• Gloves: To protect your hands from sharp edges and water.
• Flashlight: To illuminate the work area.

Beyond the Repair: When to Call a Professional

• Lack of experience: If you’re not comfortable working with electrical components or plumbing, it’s best to leave the repair to a qualified technician.
• Unusual symptoms: If the dishwasher exhibits other unusual symptoms beyond drainage issues, such as leaks or malfunctioning controls, it’s advisable to seek professional assistance.
