Kitchen disposals take hard use, and most failures fall into a few patterns. A hum with no spin is a jam. Water under the sink is a leak at the sink flange, the body or a hose connection. A sink that drains slowly may have nothing to do with the disposal at all.
Never put a hand in the disposal, even when it is off at the switch. Turn off the power at the wall switch or the breaker before anyone works on it.
What the symptom usually means
| Symptom | Likely cause | Typical fix |
|---|---|---|
| Hums, does not spin | Jammed flywheel | Clear the jam and reset. |
| Silent, no hum | No power or tripped reset | Check reset button, switch and wiring. |
| Leaks from the top | Sink flange seal failed | Reseat the flange. |
| Leaks from the side or bottom | Body seal or cracked housing | Usually replace the unit. |
| Sink backs up | Clog beyond the disposal | Clear the drain line. |
Repair or replace
If the unit is jammed or tripped, repair is quick. If the housing leaks or the motor is worn out, replacement is the sensible choice. Disposals do not last forever, and putting money into an old one rarely pays.
When we replace a unit, we match the mounting, check the dishwasher connection and test the drain before we leave. Customers sometimes buy a unit at a store, and we can install it, though we check the fit first.
Disposal jammed or leaking?
Call and describe the sound or the leak.
The dishwasher connection
A dishwasher drain hose usually joins at the disposal. If that connection leaks, or the knockout plug was never removed on a new unit, the dishwasher drains slowly or backs up. We check this on every install.
What not to put down the disposal
- Grease, oil and fat, which cool and coat the drain line.
- Fibrous or stringy scraps, such as celery, corn husks and artichoke leaves.
- Coffee grounds in large amounts, which pack into a sludge.
- Bones, pits and large seeds.
- Starchy items like pasta and rice, which swell in the line.
Kitchen drains in Monterey Park homes and condos
In older homes, the line from the kitchen sink may be narrow, rough inside or partly scaled. In condos, a shared stack serves several units. If your sink and disposal are fine but the sink still backs up, the blockage may be past your unit. That is a drain cleaning job and sometimes a hydro jetting one.
What affects the cost of garbage disposal repair
Cost factors we explain before work starts
A reset is nearly free of parts, a new unit is not, and the drain behind the disposal is its own question.
Disposal repair and replacement are maintenance items. Water damage from a sudden supply failure may be covered, so photograph it and ask your insurer.
