How to Effortlessly Replace Your KitchenAid Dishwasher Float Switch: Tips and Tricks You Need to Know

Is your Kitchenaid dishwasher leaving puddles on the floor? A malfunctioning float switch could be the culprit. This essential component prevents overfilling and potential flooding by triggering the water inlet valve to shut off when the water level reaches a certain point. When it fails, water can continue to flow, leading to a soggy mess.
This guide will walk you through the process of how to replace Kitchenaid dishwasher float switch, equipping you with the knowledge and confidence to tackle this common repair.

Understanding the Float Switch

The float switch is a simple yet crucial component in your dishwasher. It consists of a buoyant ball connected to a lever or switch that activates when the water level rises. This triggers the water inlet valve to shut off, preventing the dishwasher from overflowing.
Over time, the float switch can become clogged with debris, corroded, or simply wear out. When this happens, it may not activate properly, leading to water leaks and potential damage.

Identifying the Problem

Before embarking on a repair, it’s crucial to confirm that the float switch is indeed the culprit. Here are some common signs indicating a faulty float switch:

• Water leaks: Standing water around the dishwasher is a clear indication of a problem.
• Dishwasher won’t fill: A malfunctioning float switch might trigger the water inlet valve to shut off prematurely, preventing the dishwasher from filling properly.
• Dishwasher won’t drain: A clogged float switch can obstruct the drain hose, preventing water from draining effectively.
• Erratic operation: The dishwasher may exhibit inconsistent behavior, such as filling and draining intermittently.

Tools and Materials You’ll Need

To replace the float switch, you will need:

• A Phillips screwdriver: This is essential for removing screws.
• A flathead screwdriver: This might be needed to pry off certain covers.
• New float switch: Order the correct replacement part for your specific Kitchenaid dishwasher model.
• Gloves: Protect your hands from potential water and debris.
• A flashlight: For illuminating the work area.
• Optional: Multimeter: This can be used to test the float switch’s functionality.

Step-by-Step Guide to Replacing the Float Switch

Now that you have the necessary tools and materials, let’s proceed with the replacement process:
1. Disconnect Power: Before working on any electrical appliance, always disconnect the power supply. Unplug the dishwasher or turn off the circuit breaker to the dishwasher.
2. Locate the Float Switch: The float switch is usually located in the bottom of the dishwasher tub. It might be covered by a plastic cover or a metal plate. You might need to remove some screws to access it.
3. Remove the Old Float Switch: Once you locate the float switch, carefully remove it. This might involve disconnecting wires or releasing clips depending on the model.
4. Install the New Float Switch: Align the new float switch with the mounting points and carefully connect it. Ensure the wires are securely connected in the correct positions.
5. Reassemble the Dishwasher: Put everything back in place, making sure all screws are securely tightened.
6. Test the Float Switch: Reconnect the power supply. Run a cycle with a small amount of water to test the new float switch. Observe if the dishwasher fills and drains properly, and if the water level stops at the appropriate point.

Troubleshooting and Tips

• Clean the Float Switch: Before replacing the float switch, consider cleaning it. If the problem is due to debris clogging the switch, cleaning might be sufficient.
• Test the Float Switch: If you have a multimeter, you can test the functionality of the float switch before replacing it. This will help to confirm if the switch is indeed faulty.
• Check the Water Inlet Valve: If the float switch is working correctly but the dishwasher still overfills, the problem might lie with the water inlet valve.
• Professional Help: If you are unsure about replacing the float switch or encounter any difficulties, it’s best to seek professional help from a qualified appliance technician.
