Garbage Disposal Leaking From the Reset Button? What It Means
Water dripping from the bottom of the disposal, right around the red button, is the one leak you cannot tighten your way out of. Here is why.
If your garbage disposal is leaking from the reset button, an internal seal has almost certainly failed, letting water from the grinding chamber reach the motor housing and drip out through the openings at the bottom. On household disposals that seal is not designed to be serviced by owners, so the usual fix is replacing the disposal. Stop using it, unplug it or switch off its breaker right away, because water is reaching the area around the motor and its electrical parts.
Before you buy a new unit, spend five minutes confirming where the water is really coming from. Water from a loose dishwasher hose or sink flange often runs down the outside of the disposal and drips off the bottom, which can look like a reset-button leak.
Why the reset button area leaks
A disposal has two zones: the grinding chamber at the top, which is always wet, and the motor below it, which must stay dry. A seal around the motor shaft separates them. Over years of use, vibration, heat cycles and wear can break down that seal, or corrosion can open a crack in the chamber housing. Once that happens, water seeps into the motor section and finds the nearest exit, often the reset button opening or the bottom plate.
That is why this leak is different from the others. A loose clamp or a flange that needs new putty can be fixed in minutes. A failed internal seal sits inside the unit and, on most residential models, is not sold as a separate owner-replaceable part.
What you need to confirm it
- Flashlight
- Dry paper towels
- Food coloring (optional)
- A bucket or pan
How to confirm the source
- Cut power. Unplug the disposal or turn off its breaker before you touch it.
- Dry everything. Wipe the disposal body, hoses, sink flange and pipes completely dry.
- Test the top first. Put the stopper in, fill the sink with a few inches of water, add a few drops of food coloring, and let it sit. If colored water appears at the sink flange where the disposal meets the sink, that is a flange leak, which is usually fixable.
- Test the sides. Pull the stopper. Watch the dishwasher inlet and the discharge pipe joint with a paper towel in hand. Leaks there are usually clamps, gaskets or loose connections.
- Watch the bottom. If water comes out from the bottom plate or around the red button while the top and side connections stay dry, the internal seal or housing has failed.

Leak location at a glance
| Where you see water | Likely cause | Usually fixable? |
|---|---|---|
| Top, at the sink flange | Old putty, loose mounting screws | Yes |
| Side, at the dishwasher inlet | Loose clamp, damaged hose | Yes |
| Side, at the discharge pipe | Worn gasket, loose bolts or slip nut | Yes |
| Bottom plate or reset button | Failed internal seal or cracked housing | Usually means replacement |
Why repair rarely makes sense
- The parts are internal. Getting to the seal means taking the unit apart. Few manufacturers support owner repairs at that level.
- Water may have reached the motor. Even if the seal could be replaced, bearings and windings exposed to water may already be damaged.
- Corrosion spreads. One failed seal on an older unit often goes with other worn parts.
- Cost. As of 2026, professional labor for a typical disposal swap generally runs from roughly $140 to $270 in national cost guides, before the cost of the unit. That is often comparable to or less than a bench repair. Prices vary by region.
Do not try to seal the bottom with silicone, tape or epoxy. That traps water inside the motor housing and does nothing about the leak at the source.
Check the warranty first
Many disposals come with multi-year manufacturer warranties, and some brands offer in-home service or a replacement unit for a covered failure. Find the model and serial number on the label on the disposal body, then check the manufacturer’s warranty terms. InSinkErator, for example, links its warranty information and replacement guide from its support site. Some brands use the same mounting system across models, which can make a replacement quicker if you stay with the brand.
What to do while you wait for a replacement
- Leave the disposal unplugged or the breaker off.
- Scrape food scraps into the trash or compost.
- Avoid running the dishwasher if it drains through the disposal, since dishwasher water will pass through the leaking chamber.
- Put a pan under the unit and dry the cabinet floor so the wood does not swell or grow mold.
When to call a pro
A replacement disposal is a reasonable DIY job if you are comfortable with drain connections and the unit plugs into an outlet. Call a plumber if the drain pipes are corroded, the cabinet floor is soft or stained, or the new unit needs different trap alignment. Call a licensed electrician if the unit is hardwired and you are not confident with wiring, or if the leak has reached the outlet or junction box. Our guide on installing a garbage disposal with a dishwasher covers the swap.
Bottom line
A leak from the reset button almost always means water is getting past an internal seal into the motor section. Cut the power, confirm the top and side connections are dry, check the warranty, and plan on replacing the disposal rather than patching it.
FAQ
Can I replace just the seal?
On most household disposals, no. The seal is internal and not sold as an owner part. Ask the manufacturer for your specific model, but replacement is the usual answer.
Is it dangerous to keep using a leaking disposal?
Water near the motor and electrical connections is a hazard. Stop using it and keep it unplugged until it is replaced.
How long do disposals last before this happens?
It varies with use, water quality and model quality. Seal failures are more common in older units that have seen years of daily use.
Could the leak be from the dishwasher instead?
Yes. A loose dishwasher hose can drip down the outside of the disposal. Dry everything and watch the inlet during a dishwasher drain cycle to rule it out.
