The Surprising Truth About Dishwasher Float: What It Is And Why It Matters

- A float is a buoyant device that rises and falls as the water level in the dishwasher changes.
- The dishwasher float is typically located in the bottom of the dishwasher tub.
- Replacing a dishwasher float is a relatively simple task that can be completed in a few steps.
A dishwasher float is an integral component of a dishwasher’s operation. It serves as a safety mechanism to prevent overflows and water damage. A float is a buoyant device that rises and falls as the water level in the dishwasher changes.
How Does a Dishwasher Float Work?
The dishwasher float is typically located in the bottom of the dishwasher tub. It is connected to a switch that controls the water inlet valve. As water enters the dishwasher, the float rises. When the water level reaches a predetermined height, the float triggers the switch, which shuts off the water supply. This ensures that the dishwasher does not overfill.
Types of Dishwasher Floats
There are two main types of dishwasher floats:
- Polystyrene Float: A lightweight, disposable float made of polystyrene foam. It is the most common type of float found in dishwashers.
- Mechanical Float: A more durable float made of metal or plastic. It is less likely to fail than a polystyrene float, but it can be more expensive.
Signs of a Faulty Dishwasher Float
A faulty dishwasher float can lead to several issues:
- Dishwasher Overflows: If the float fails to shut off the water supply, the dishwasher may overflow and cause water damage.
- Dishwasher Not Filling: If the float is stuck in the “up” position, the dishwasher may not fill with water, preventing it from operating properly.
- Dishwasher Runs Continuously: If the float is stuck in the “down” position, the dishwasher may run continuously, wasting water and energy.
Troubleshooting a Dishwasher Float
If you suspect that your dishwasher float is faulty, you can troubleshoot the issue by:
- Inspecting the Float: Check the float for any damage or obstructions.
- Testing the Float: Manually raise and lower the float to see if it triggers the switch properly.
- Replacing the Float: If the float is damaged or faulty, it will need to be replaced.
How to Replace a Dishwasher Float
Replacing a dishwasher float is a relatively simple task that can be completed in a few steps:
1. Unplug the dishwasher and turn off the water supply.
2. Remove the access panel at the bottom of the dishwasher.
3. Locate the float and disconnect it from the switch.
4. Install the new float and reconnect it to the switch.
5. Replace the access panel and turn on the water supply.
Preventing Dishwasher Float Problems
To prevent dishwasher float problems, you can:
- Regularly Clean the Dishwasher: Remove food particles and debris that can clog the float or switch.
- Use a Rinse Aid: A rinse aid helps to prevent water spots and buildup on the float and switch.
- Have the Dishwasher Serviced Regularly: A professional technician can inspect the float and switch for any potential issues and make necessary repairs.
Final Note: Safeguarding Your Dishwasher with a Functional Float
A properly functioning dishwasher float is essential for the safe and efficient operation of your dishwasher. By understanding how a float works, troubleshooting common problems, and taking preventive measures, you can ensure that your dishwasher operates smoothly and without any water-related mishaps.
