Disposal symptoms
| Symptom | Likely cause | Safe first step |
|---|---|---|
| Hums but does not spin | Jammed by a hard object or fibrous food | Power off, then use the hex key slot under the unit to free it |
| Does nothing at all | Tripped reset button or breaker | Press the reset button on the bottom of the unit |
| Water leaking from the bottom | Failed internal seal | Usually means replacement |
| Leaking at the side connections | Loose dishwasher or drain connection | Tighten or reseal; often repairable |
| Drains slowly | Clog in the trap or kitchen branch line | Do not keep running the disposal; clear the drain |
Keep these out of the kitchen drain
- Cooking grease, oil and fat, even with hot water.
- Coffee grounds and eggshells, which settle in the pipe.
- Fibrous scraps such as celery, onion skins and corn husks.
- Rice and pasta, which swell.
- Bones, fruit pits and non-food items.
- Chemical drain openers, which can damage the disposal and older pipe.
Why kitchen lines clog in older homes
In many Buena Park tract homes, the kitchen sink drains through a branch line that may be original cast iron or galvanized pipe. Over the years, grease cools and sticks to the inside of the pipe, catching food particles until the opening narrows. Rough interior walls of older pipe make that buildup worse.
A plunger or cleaning the trap can clear a clog close to the sink. A clog farther along the branch usually needs a cable machine, and a line coated with grease may be better cleaned with hydro jetting if the pipe is in sound condition.
Repair or replace the disposal
Repair
- Jams, tripped resets and loose connections.
- Often fixed quickly without new parts.
- Worth trying first on a newer unit.
Replace
- Leaks from the body or bottom of the unit.
- Motor that no longer runs after a reset.
- Repeated jams and rust on an older unit.
What to ask the plumber
- Is the clog in the trap, the branch line or farther along?
- Would you snake or jet this line, and why?
- Is the disposal repairable, or is a replacement more sensible?
- Is the dishwasher connection installed correctly?
- What is the written price for the repair?
Common questions
- Is it safe to use a chemical drain cleaner?
- It is best avoided. Chemicals can damage disposals and older pipe, and they make the water dangerous for anyone who has to clear the drain afterward.
- Why does the dishwasher back up into the sink?
- They often share a drain. A clog in the kitchen branch or trap can push dishwasher water into the sink. Clearing the line usually fixes it.
- Do I need an electrician to replace a disposal?
- If the existing wiring is in place and correct, a plumber usually connects the new unit. New wiring or a new outlet may need an electrician.
