In this video
Shut off all power to the disposer at the breaker panel. If the disposal plugs into the wall, unplug it. If it's hardwired, remove the access panel to the wires and undo the electrical connections. Turn off the water supply to the sink. Place a bucket or pan underneath the disposer to catch any water. Detach the disposer from the drain pipe. If there's a drain tube from the dishwasher, detach that as well. Insert a screwdriver into the locking ring and unlatch the old disposer, carefully lowering it.

FAQs
What are the most critical safety steps to take before starting to disconnect the old dishwasher?
Always turn off the water supply valve leading to the dishwasher and cut power at the circuit breaker first. This prevents potential leaks, electrical shocks, and damage while working with water lines and electrical connections.
What are the most common causes of leaks when connecting the hot water supply line and drain hose, and how can I prevent them?
Leaks often stem from improperly tightened connections or insufficient Teflon tape on threaded fittings. Ensure fittings are hand-tightened, then turn an additional 1/2 to 1 full turn with a wrench, and apply Teflon tape only to male threaded connections to create a watertight seal.
The project is listed as 'beginner' with an estimated 5 hours; is this realistic for someone with no plumbing experience, and what factors might extend the timeline?
While beginner-friendly, 5 hours is an estimate for straightforward installations. If you encounter seized fittings, rusted pipes, or need to adjust cabinetry, it could take longer. Having all tools and materials ready beforehand will help keep you on track.
Besides the listed tools, what other items should a beginner have on hand in case of unexpected issues during removal or installation?
A small shop-vac for unexpected spills is invaluable. Additionally, having a utility knife to cut the drain hose to length and possibly a basin wrench if the old water supply connection is in a very tight spot could save you a trip to the hardware store.
