Jam, leak or dead unit: sorting out what you have
Three different failures look alike from the sink. The sound and the location of water tell most of the story.
| What you notice | Likely problem | What happens next |
|---|---|---|
| Loud hum, blades do not turn | Jam from a utensil, bone or fibrous food | Clear the jam, reset the unit |
| Silence, no hum | Tripped reset, breaker or dead motor | Check the reset button and outlet, then test the motor |
| Water in the cabinet | Leak at the flange, hose or body | Find the joint, repair or replace |
| Sink fills and does not drain | Clog past the disposal | Clear the drain line |
| Burning smell or smoke | Motor failure | Unplug or switch off, replace the unit |
If the unit is hardwired and the breaker keeps tripping, stop using it and call. Repeated trips mean a fault.
When a disposal leak or kitchen backup is an emergency
Treat it as urgent if water is flowing from under the sink, sewage-smelling water is coming up through the sink or dishwasher, or the unit is sparking or smoking. Turn off the disposal switch and the breaker, and close the supply valves under the sink if water is running.
Keep the cabinet empty and mop up water quickly, since particleboard cabinets swell and warp when wet. Photograph the leak and the damage before cleanup, because your policy decides what is covered and your insurer may ask.
We answer on the 24/7 line at night and on weekends, and same-day appointments are offered when available. If the problem is only a hum, it can usually wait for a scheduled visit.
Safe steps for a jammed disposal
Many jams clear in a few minutes. Follow these steps in order, with the power off.
- Turn off the switch and unplug the unit.
If it is wired in, switch off the breaker. A disposal that starts by surprise can injure you.
- Look with a flashlight.
Use tongs or pliers to lift out visible objects. Never use your fingers.
- Turn the blades by hand.
Many units have a hex socket at the bottom. A hex wrench turned back and forth frees a stuck impeller.
- Press the red reset button.
It sits on the bottom of the unit and trips when the motor overheats.
- Test with cold water running.
If it still hums or leaks, stop and call.
Where disposals leak
A disposal has three common leak points. The top flange where the sink meets the unit can weep when the putty or gasket dries out. The dishwasher inlet and the drain outlet connect to hoses and pipe that can loosen. A leak from the body or the seam near the bottom means the shell has failed, and the unit is finished.
A flashlight and a dry paper towel help pinpoint the source. Run water for a minute and watch each joint. If the water appears at the body or from the housing seam, repair is not worth the money, and replacement is the honest recommendation.
Water in the cabinet and nobody to ask?
Call the 24/7 line, and we will tell you what to shut off and when a plumber can reach you.
Electrical faults: what a plumber checks
A silent disposal is not always dead. We check the reset button, the switch and the outlet first, then whether the unit has power. If power arrives and the motor does not respond, the motor or its start capacitor has failed.
Wiring behind a disposal switch is electrical work, and a licensed electrician should handle any fault in the circuit itself. If you are unsure whether the problem is the unit or the circuit, we can tell you which trade to call. If your unit runs from a countertop air switch, that button can fail too.
Repair or replace the disposal?
Age, horsepower and the type of damage decide it. Here is the comparison we use.
| Condition | Repair | Replace |
|---|---|---|
| Jam, no damage | Yes, often no parts needed | Not needed |
| Worn flange gasket or loose hose | Yes | Only if the unit is old |
| Leaking body or seam | No | Yes |
| Seized or burnt motor | Rarely worth it | Yes |
| Frequent jams on a small unit | Cleaning helps | Consider a higher horsepower model |
Units wear out. If yours is old and leaking, a new one costs less than repeated repairs.
Adding or replacing a disposal in a Wildwood kitchen
Installing a new disposal means mounting the flange, connecting the drain and, if you have a dishwasher, opening its knockout plug so the dishwasher hose can drain through the unit. Forgetting the plug is a common reason a dishwasher fills with water after a new install.
St. Louis County guidance has said a plumbing permit is required to replace or reset sinks and to install dishwashers when countertops or cabinets are replaced. That flyer is dated 2013, so confirm current rules with the building department. A like-for-like disposal swap is a different job, and we can explain how it fits.
Septic and package-plant homes need extra thought. The city's Master Plan says much of Wildwood's soil is unsuitable for individual septic systems and that some subdivisions use package treatment plants. Food waste adds solids to those systems, so ask your septic or treatment provider whether a disposal is a good idea.
What affects the price of garbage disposal repair
A simple jam is a short visit, and a new installation takes longer. These factors set the price.
A reset is quick, but a new unit adds parts and labor.
Heavier-duty models cost more and run quieter.
Corroded drain pieces, old traps and dishwasher connections may need replacing.
A hardwired unit or a missing outlet may need an electrician.
After-hours calls cost more than scheduled visits.
A burst hose that floods a floor may be covered, while a slow leak under the sink often is not. Your policy decides.
Describe the unit and the problem when you call us, and we will give a clear price before work starts.
