Step 1 · Turn Off Power and Prepare Workspace

Begin by ensuring your safety and preparing the work area. Go to your home's electrical panel and turn off the circuit breakers that supply power to both the garbage disposal and the dishwasher. To be certain the power is off, try flipping the garbage disposal switch at the wall. Clear out all items from under the sink cabinet to create ample space to work. Place a bucket and some old rags or paper towels under the sink to catch any residual water.
