|Replacing a heating element |
|Disconnect the power source to your dishwasher before you conduct this or any other test. 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. |
Locate your dishwasher's heating element. Open the dishwasher door and look into the tub. It is the thin, circular tube at the base of your dishwasher. It may or may not be covered. If it is covered, remove the lower dishrack, and then remove the cover.
Your heating element is going to have two metal terminals. One at each end. Each terminal reaches downwards, into the base of the dishwasher. Mentally mark the area where each terminal enters the base of the tub.
Now you need to gain access to the heating element's wiring. You can do this by first removing the lower kickplate panel of the dishwasher. There will be at least two screws (but maybe four) holding the kickplate panel in place. They are located either on the top or the bottom of the panel. If the screws are located on the top, you may need to open the dishwasher door in order to gain access to them. Close the door to remove the panel, though.
Now look into the lower access area that you have just uncovered. Pinpoint the area where the heating element terminals extend through the base of the dishwasher. They will each have a wire connected to it. Label each of the wires so that you will be able to properly reconnect them later. Now you can pull the wires off the terminals.
Each wire is connected to a terminal using a slip-on connector. Grasp the connector and pull on it firmly. DO NOT pull on the wire itself. Pull only from the connector. You may decide you need to use a pair of needle nosed pliers to help you.
Both terminals are secured in place with a lock nut. You can use a crescent wrench or a pair of pliers to losen, and then remove each lock nut. Reach into the dishwasher and lift the element out. Discard it. Situate your new heating element in place of the old one. Slip the terminals through the holes in the base of the dishwasher. Replace each of the lock nuts. Use a crescent wrench or a pair of pliers to tighten them in place. Now reattach each of the wires - remember, you labeled them earlier so you'd know which one leads to which terminal. Put the lower kickplate panel back in place. If you removed a heating element cover, replace it now. Replace the lower dishrack, and close the dishwasher door. Restore power to your dishwasher.
You do not have to remove the heating element from the dishwasher in order to test it. Just make sure power is not getting to your dishwasher before you conduct the test.
