Un-jam the disposer if you hear humming, or buzzing when you turn it on. Unplug the disposer from the outlet, or flip the circuit breaker switch to the "Off" position. Remove the stopper and splash guard and insert a wooden broom handle into the disposer. Then try to un-jam the turntable by hooking the broom handle end onto a cutter and pushing. Try different directions until the disposer is free, then remove any residue, like seafood shells, using barbecue tongs.
Reset the Waste King SS2600 once the turntable moves, and if the disposer won't turn on again. Press the red button near the power cord. It may be tricky to see it depending on installation, but it's on the opposite side of the power cord. Turn the disposer back on and try the job again with plenty of water.
Insert the correct kinds of foods into the disposer. Hard materials like coconut shells, large bones, bottle caps, and seafood shells will cause the waste disposal to jam. Add lots of water to dispose of fibrous materials like small corn husks after grinding. Avoid drain cleaner, and non-food items like china, utensils and aluminum foil.
Insert the included stopper in the sink and fill the sink half full of water if the disposer starts to smell. Add a box of baking soda and allow the mixture to drain slowly. The odor problem will be corrected.
