Jam, motor or leak: sort it in three questions
| Symptom | Likely problem | Repair or replace |
|---|---|---|
| Loud hum, blades do not turn | Jammed flywheel | Usually repair: free the jam, check for damage |
| Silent, no hum, reset button popped | Overheated motor or tripped overload | Reset once. If it trips again, replace |
| Dead silent, reset does nothing | Dead outlet, switch or burned-out motor | Test power first, then likely replace |
| Water at the top ring | Failed sink flange seal | Reseal or reinstall, often repair |
| Water at the side hose | Loose dishwasher or drain connection | Tighten or replace the hose, repair |
| Water from the housing bottom | Cracked housing or failed internal seal | Replace the unit |
That third leak is the clearest sign of an end-of-life disposal. A unit that drips from the lower housing cannot be sealed from outside, so repair costs more than it saves.
Safe steps to take right now
Safe to do yourself
- Switch the disposal off at the wall and unplug it if there is a plug
- Shine a flashlight in and lift out anything you can see with long tongs
- Press the red reset button on the bottom after it has cooled
- Insert a hex key into the bottom socket and work it back and forth to free a jam
Leave it to a plumber
- Reaching a hand or fingers into the chamber, ever
- Running it again after water appears under the cabinet
- Any wiring beyond the plug, switch or cord
- Removing the unit when the sink drain line behind it is also blocked
If the hex key moves freely and the reset holds, run cold water and test briefly. If it hums again with no movement, stop. Forcing a jammed motor burns it out.
What never belongs in a disposal
A disposal grinds food, but it does not move it far. Everything it creates still has to travel down the kitchen drain, and that is where trouble builds. Jordan Basin Improvement District says not to pour cooking grease down any drain, even with a disposal. Put it in the trash.
Grease cools in the pipe, coats the walls and catches scraps until the line narrows. That is also why a sink can back up with a perfectly healthy disposal.
- Cooking oil, fat and bacon grease
- Coffee grounds in quantity, which pack like sand
- Rice, pasta and bread, which swell with water
- Fibrous food such as celery, corn husks and potato peels
- Bones, fruit pits and anything hard
- Glass, metal, plastic, rubber bands or cleaning rags
What to do before anyone touches the disposal
- Cut the power at the switch and the breaker.A disposal that looks dead can still start. Never rely on the wall switch alone.
- Keep hands out of the opening.Do not reach into the chamber, even with the power off. Use tongs or pliers for anything you can see.
- Close the sink drain.If water is leaking, put a bucket under the unit and keep the faucet off until the leak is found.
- Skip the chemicals.Do not pour drain cleaner into a jammed disposal. It splashes back and can burn skin and eyes.
Disposal stuck or leaking now?
Call the 24/7 line. Tell us what the unit does when you flip the switch, and we will say whether it can wait for a same-day visit.
When a disposal should be replaced
Repair makes sense for a jam, a loose hose or a loose flange. Replacement makes sense when the motor is dead, the housing leaks or the unit has jammed repeatedly with the same grinding noise. A cheaper unit does not always mean lower cost if it needs another call a year later.
When we replace one, we match the mounting ring to your sink, hook up the drain and dishwasher line, and test it with water running. If your dishwasher connection leaks at the disposal, we fix it at the same visit.
Planning to install a new disposal
Installs go faster when there is an outlet under the sink and the cabinet has room for the unit. If either is missing, tell us on the call. A disposal tied into a drain that is already slow should have that line checked first.
Kitchen sink clogs and the sewer line behind them
If water backs up into the sink when the disposal runs, the blockage may sit past the disposal, in the kitchen drain line. A cable machine clears most of these. See drain cleaning for how that works.
Jordan Basin Improvement District offers a simple check. If you find standing water at your cleanout, the blockage is likely between the house and the sewer main. If you find none, the problem is likely inside the house.
The district maintains the main. The private line from home to main belongs to the homeowner.
Do not run the disposal while the sink is full of backed-up water. You will only push waste into a line that cannot take it.
What disposal repair costs
Repair or replacement
A jam or loose seal costs far less than a unit that has to be swapped.
Size and type of unit
Horsepower and build quality change the unit price. Larger households usually want a stronger motor.
Connections
Dishwasher hose, drain trap and electrical plug all affect labor and parts.
Drain condition
A kitchen line that needs clearing adds drain work.
After hours
A late-night call on a flooding sink is different from a morning appointment.
Insurance usually does not cover a disposal that fails from wear, though sudden water damage from a sudden failure may be covered, so check your policy. Call the 24/7 line for a clear price before work starts.
Rules and sources behind this page
Disposals connect to both the drain and the home's electrical circuit, so the plumbing side follows the IPC. Utah Code 15A-2-103 adopts the 2024 International Plumbing Code (IPC) as the state plumbing code, effective July 1, 2026, with Utah amendments on top. Wiring is a separate trade, and a plumber will tell you when an electrician needs to look at the circuit.
According to Jordan Basin Improvement District guidance, cooking grease should go in the trash instead of down the drain, even with a disposal running. That guidance applies to every Riverton kitchen.
Disposal questions
Yes. The line is open 24/7. If the sink is flooding or leaking into the cabinet, turn the unit off and call. Same-day appointments are offered when available for repairs that can wait.
The blades are jammed against something. Turn it off, unplug it, and work a hex key in the bottom socket to free it. Never use your hand.
Look at where it drips. The top ring points to the flange seal. The side points to a hose or drain connection. The bottom of the housing means the unit is failing and should be replaced.
A jammed disposal can slow the drain, and waste past it can pile up and block the kitchen line. A clear cleanout test tells you which side of the house the blockage is on.
It depends on the unit and how it is treated. Grease, bones and fibrous scraps shorten its life, while steady cold water and sensible loads help. A leaking housing means it is finished.
A licensed plumber can handle the drain and water connections and the plug. You can check any plumber's license with the Utah Division of Professional Licensing lookup, searching by name or license number under PLUMBER.
Yes, the drain hose and its connection to the disposal. For a faucet that is dripping at the same sink, see faucet repair.
