What To Know
- The float switch consists of a float that rises and falls with the water level in the dishwasher tub.
- As the water level rises, the float lifts and triggers a switch that activates the pump to drain the water.
- If the dishwasher fails to drain water after a cycle, the float switch may be stuck in the “up” position, signaling that the tub is full even when it’s not.
A float switch is a crucial component in your KitchenAid dishwasher that prevents flooding by detecting water levels and triggering the pump to drain excess water. If your dishwasher is leaking or not draining properly, it’s essential to check the float switch for potential malfunctions. In this comprehensive guide, we’ll delve into the float switch for KitchenAid dishwashers, covering its function, diagnosis, reset, and replacement procedures.
Function of a Float Switch
The float switch consists of a float that rises and falls with the water level in the dishwasher tub. As the water level rises, the float lifts and triggers a switch that activates the pump to drain the water. This mechanism ensures that the water level remains within a safe range, preventing overflow and potential damage to your kitchen and home.
Signs of a Faulty Float Switch
Several symptoms can indicate a faulty float switch in your KitchenAid dishwasher:
- Dishwasher not draining: If the dishwasher fails to drain water after a cycle, the float switch may be stuck in the “up” position, signaling that the tub is full even when it’s not.
- Dishwasher leaking: A faulty float switch can allow water to accumulate in the dishwasher tub, leading to leaks.
- Dishwasher cycling repeatedly: If the dishwasher keeps starting and stopping the drain cycle repeatedly, the float switch may be malfunctioning and sending inconsistent signals to the pump.
- Dishwasher error codes: Some KitchenAid dishwashers may display specific error codes related to the float switch, such as “F6E1” or “F6E3.”
How to Diagnose a Faulty Float Switch
Before replacing the float switch, it’s essential to diagnose the issue accurately:
1. Check the water level: Open the dishwasher door and inspect the water level in the tub. If the water level is high or overflowing, the float switch may be stuck in the “up” position.
2. Test the float switch: Manually lift and lower the float switch located at the bottom of the dishwasher tub. If the switch doesn’t move freely or if it doesn’t trigger the pump when lifted, it may be faulty.
3. Inspect the float switch connections: Check the electrical connections to the float switch. Loose or damaged connections can prevent the switch from functioning properly.
How to Reset a Float Switch
If the float switch is stuck in the “up” position, you can try to reset it:
1. Unplug the dishwasher: Disconnect the dishwasher from the power outlet.
2. Access the float switch: Locate the float switch at the bottom of the dishwasher tub.
3. Lift and release the float: Gently lift the float and release it several times to dislodge any debris or obstructions.
4. Reconnect the dishwasher: Plug the dishwasher back into the power outlet and start a test cycle.
How to Replace a Float Switch
If the float switch is faulty and cannot be reset, it needs to be replaced:
1. Gather tools and parts: You’ll need a screwdriver, a pair of pliers, and a new float switch compatible with your KitchenAid dishwasher model.
2. Unplug the dishwasher: Disconnect the dishwasher from the power outlet.
3. Access the float switch: Locate the float switch at the bottom of the dishwasher tub.
4. Disconnect the wires: Use the screwdriver to disconnect the electrical wires from the float switch.
5. Remove the float switch: Use the pliers to gently remove the float switch from its mounting bracket.
6. Install the new float switch: Position the new float switch in the mounting bracket and secure it with the pliers.
7. Connect the wires: Reconnect the electrical wires to the new float switch using the screwdriver.
8. Test the dishwasher: Plug the dishwasher back into the power outlet and start a test cycle to ensure the new float switch is functioning properly.
Troubleshooting Tips
If you’re experiencing problems with your KitchenAid dishwasher after replacing the float switch, here are some troubleshooting tips:
- Check the drain hose: Ensure the drain hose is not kinked or blocked, as this can prevent the dishwasher from draining properly.
- Inspect the drain pump: The drain pump may be faulty or clogged, preventing the dishwasher from draining water.
- Reset the dishwasher: Unplug the dishwasher and wait a few minutes before plugging it back in. This may reset the dishwasher and resolve any temporary issues.
- Call a qualified technician: If you’re unable to resolve the issue yourself, contact a qualified appliance technician for further assistance.
