| || Replacing a float assembly|
|Disconnect the power source to your dishwasher before you conduct this or any other repair. Either unplug the unit from the wall outlet, remove the appropriate fuse from the fuse box, or flip the appropriate breaker in the circuit breaker panel.|
Your float assembly is found inside the dishwasher's tub, on the bottom. The water that fills your dishwasher lifts the float, and when it reaches a certain level, it acts as a trigger for the float switch. The float triggers the float switch to shut off, thereby shutting off the flow of water into the dishwasher.
Open the dishwasher door and remove the lower dishrack. If your dishwasher has a cover over your float assembly, remove it now. A float's cover is stationary - it does not move up and down. It will either snap in place, or be held in place with a screw.
Floats usually snap into place, and replacing it is fairly simple: insert the new float assembly where you've just removed the old one. However, if you are unable to remove yours just by pulling on it, it may be connected to the float switch. If this is the case, you will need to disconnect it from the switch.
On some models, the assembly's throat is removeable, and on some they are not. If the float assembly throat on your dishwasher is removeable, it will likely screw out or be held in place with nuts, and you should remove it now.
Now, if your float is attached to the float switch, you can access the area where they meet by removing the lower kickplate panel. This panel will either be held in place with a few screws, hooks, clips, or pressure snaps. If no screws are present, the panel should lift up and off, or it should pull off straight out towards you.
The float switch connects to an actuator lever that is attached to the float switch. Disconnect the lever from the switch and discard old float assembly. Replace with new float assembly and attach the actuator lever to the float switch. If you have removed the throat, replace that now too. Replace the lower kickplate panel and dishrack. Close the door and restore power to the dishwasher.
