Place a catch bucket beneath the disposal's drain trap. Use channel-type pliers to disconnect the slip-nut fittings on the drain trap, and remove the trap. It's not uncommon for water to spill out of the pipes as you disconnect them.
The trap will be full of water and, most likely, food waste. Carefully dump it out into the bucket. Have paper towels or rags nearby for any accidental spills. Check for clogs or obstructions in the trap fitting.
Most often, clogs will occur in the sharp bend of the trap. A small scrub brush is the most effective way to dig out any debris. You can also use a straightened coat hanger or other wire. If the clog isn't in the trap, it may lie in the trap arm, the horizontal drain piece that connects the trap to the branch drain pipe going into the wall. You can remove the trap arm by loosening the slip nut where the arm meets the vertical branch drain and pulling out the arm.
Clean inside the trap arm with a brush or wire. If the P-trap and trap arm were relatively clean when you removed them, the clog is likely in the branch drain leading to the home's main drain. The best way to clean this line is by snaking it with a drain snake, or auger.
A simple foot drum auger sold and home centers and hardware stores usually does the trick. Feed the auger cable into the branch drain from under the sink, turning the drum as you go to work the cable past pipe bends and break up the clog. Run the cable out and back through the drain a few times to be sure the clog is cleared.
Reinstall the trap arm and P-trap, tightening the slip nuts just snug. Check the positions of the pieces and make sure the trap arm slopes downward slightly toward the branch drain. When all looks good, tighten the nuts all the way by hand. If necessary, tighten them a bit further with channel-type pliers, but be careful not to over-tighten, which can damage the nuts or threads. Run water down through the disposal for several minutes to flush any loose debris through the drain system.
When you're sure the drain is working properly, you can do a bigger flush by putting a stopper over the disposal opening, filling up the sink basin with hot water, and quickly pulling out the stopper.

The cause of a clogged garbage disposal can be hard to locate because the clog can come from one item, several items over time, several items at once, or a non-food object.
A garbage disposal clog can also originate in the blades, inside the construction, or inside the sink drain. It's important to understand the cause behind a clogged garbage disposal so you can properly address the issue. One common misconception about garbage disposals is they can handle any food you stuff inside, including all food parts. This is not true. Hard to chop: Bones, pits, corncobs, seeds, and ice cubes are too difficult for a garbage disposal to handle. Prevent the passage of food and water: Grease, fat, and oil harden and clog the disposal and drain.
Coffee grounds and eggshells grind into granules that are tiny and sticky, making it easy to reach small areas and cause issues. Starchy vegetables like beans and potato peels create a thick paste similar to grease, fat, and oil when hardened. The paste will clog and jam the device. Another misconception — the garbage disposal can handle tons of food at once.
This is not true, either. Testing and pushing the unit's limitations will overwhelm it. An overwhelmed garbage disposal makes a humming noise. When you peek inside the disposal with a flashlight, no food is moving around inside. When you put too much in the disposal at once, instead of concentrating on chopping only a few items at once, the disposal will do a less-than stellar job at chopping a large portion at once.
This means larger chunks get through, contributing to disposal clogs and breaking the electrical circuit near the reset switch. The only thing that should go down the garbage disposal is food. When non-food objects come in contact with the garbage disposal , it could damage your disposal.
Silverware makes a grating noise sound on contact, causing a jam in the device. Paper, fabric, foil, plastic, a washcloth, a sponge, and flower plant clippings are noise-free yet contribute to clogs and jams. Flower plant clippings, paper, and foil cut well but contribute to clogs — the wet clumps are not easy to push down the drain.
If they get stuck in the pipeline, they will prevent other items from going down the drain. Fabric, plastic, sponges, and washcloths also don't cut well on the impeller blades. A garbage disposal's attempt to grind these items will result in jamming. This is the incorrect way to use a disposal. The waste inside the device eventually builds up and prevents water from passing through.
Therefore, the correct way to use the disposal is to keep it on after the food grinding process is complete. During that time, turn on the water and let it run for one minute to clear away waste stuck inside. Then, turn off the device. The temperature of rinsing water you use to clean the garbage disposal matters — hot water is not the correct type of water. Hot water spreads fats, oils, and grease around the disposal and into the pipes.
When oils, grease, and fats dry, they harden, creating a landing spot for more food to land and form a clog. The process of cleaning a clogged garbage disposal differs greatly from cleaning a clogged drainpipe.
Some cleaning methods are useful, and some are not. A non-recommended cleaning method is liquid drain cleaners. Drain liquid cleaners are dangerous for garbage disposals because they can erode the plastic and rubber parts of the unit such as the splash guard. Always turn the garbage disposal off before attempting to clean the unit.
