Replacing a float switch
| Note: | | 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. A defective switch may interfere with your dishwasher's filling and/or draining ability.
You can gain access to your switch by removing the lower kickplate panel located just below the dishwasher door. This panel is usually held in place with a few screws. You might need to open the dishwasher door to gain access to and remove the screws. The door will have to be closed again so that you can remove the panel.
A dishwasher's float switch will sit below the float assembly. So find your float assembly inside your dishwasher, and your switch will be located directly below it in the access area. It will likely be either on the left or the right hand side. There are going to be two wires connected to the float switch. They are connected with slip-on connectors. Its a good idea to label these wires so that you are able to correctly reconnect them later. Grasp the slip-on connectors and pull firmly to remove the wires from the switch. Do not pull on the wires themselves. You may want to use a pair of needle nose pliers to help you.
The float switch may be held in place with two screws or a clip. It is also connected to the float assembly inside the tub. Either remove the screws or release the clip to detach the switch, and then disconnect it from the float.
Discard the old switch. Situate the new switch in its place. Either secure it in place with screws, or secure it with the clip. Connect the wires to the new switch and replace the lower kickplate panel. Restore electricity to your dishwasher.
