It is late, the dishes are stacked, and the sink has gone quiet in the wrong way. The garbage disposal hummed when the water ran, or it did nothing at all, and your father says it is fine and just needs a harder push. Mom knew which button to press. You do not, and he is not going to tell you.

Before anything else, find three things under the sink: the wall switch or outlet that powers the disposal, a small reset button on the bottom of the motor housing, and a hexagonal hole in the very center of the bottom where a short Allen wrench fits. Many disposals have all three. You do not need to know the brand. You need to know where these are, and so does anyone who will be in that kitchen after you leave.

What to do tonight

Turn the disposal off at its switch, or unplug it from the outlet under the sink. If there is no switch or outlet you can reach, switch off the breaker that feeds the kitchen circuit. Do this before you reach in for anything, even if the machine looks stopped.

Look into the opening for an object such as a bone, a spoon, or a bottle cap. Use tongs or the handle of a wooden spoon. Never use your hand.

Press the reset button firmly, then wait about a minute before turning the power back on. A disposal that hums and stops is often a motor that shut itself off to protect it, and the reset brings it back.

If it still hums without turning, put the Allen wrench in the bottom center and work it back and forth a few turns in each direction to free a jam. Keep the power off the whole time. Then try the reset again.

Write what you tried and whether it worked on a card, and tape it inside the cabinet door. The next person who opens that cabinet should not have to guess.

What to check so it does not happen again

Ask your father what goes down the sink and how long he runs the water while it grinds. Fibrous food, grease that cools into the drain, and running the disposal with no water are the common causes. Pick one habit to change: cold water running before and after, and no grease poured down the drain.

Check whether the sink still drains fully after a run. A slow drain is a different problem from a stuck disposal, and you should know which one you have before you call anyone.

Look at the cabinet floor under the sink for water, and at the joint where the drain pipe meets the disposal. A drip there is a job for a plumber, not something to tighten yourself.

When to call someone

Call a plumber or an appliance repair service if the reset does not hold, if you see water at the base of the unit or under the sink, if there is a burning smell, or if the wrench turns with no give at all. When you call, ask whether they will look at the disposal alone or need to see the drain too, and whether the visit covers the whole sink or only the disposal. Ask for the name of the person coming, and write it on the same card.

If your father does not want anyone in the house, that is worth its own conversation, and it is a different conversation from the sink. The Local Help for a Widowed Father in St. Louis page lists who to call, and Start Here: The First Hundred Days explains how to begin without making it a fight.

Good week card

Tonight the sink drained, the disposal turned, and nobody had to guess which button to press.
