DIY steps
- Shut off power to the dishwasher at the circuit breaker or fuse box, and verify the power is off using a non-contact voltage tester. Wear protective gloves and safety glasses to prevent injury from sharp edges or electrical shock.
- Disconnect the water supply line if the model must be pulled out, and place a bucket under the connection to catch water. Remove the mounting screws or brackets specified by the manufacturer, then pull the dishwasher out only as far as needed to access the element terminals underneath.
- Locate the heating-element terminals and mounting nuts beneath the dishwasher tub. Follow the model procedure to disconnect the approved terminals and remove the element, noting all clips and brackets.
- Install the new heating element with the supplied gasket and the manufacturer-specified mounting hardware. Reuse only approved terminal connections; do not substitute wire nuts.
- Reassemble the dishwasher, restore the water supply, and check the element seal and supply connection for leaks while electrical power remains off. Restore power only after confirming there are no leaks.
- Plug in the dishwasher and test the heating element by running a cycle. Check for leaks and proper heating function using a multimeter to verify the element is working correctly.
