Your disposal hums but won't spin โ the impeller plate is jammed. It's completely silent when you flip the switch โ the thermal overload protector has tripped or the motor has failed. Water drips from the sink collar โ the sink mounting gasket has deteriorated. Each of these is a different diagnosis, and each has a different solution. Masters Plumbing Service's techs in Dane, WI arrive with the jamming tools, reset wrench, and replacement units to resolve any disposal failure same visit.

We carry replacement units on the truck in common horsepower ratings so a same-day swap is possible when the motor has genuinely failed.
Hum but no spin: jammed impeller. No sound at all: tripped thermal overload or failed motor. Intermittent operation: loose wiring at the switch or disposal unit. Continuous drain from the sink collar: failed sink flange gasket. Leak from the side: dishwasher drain hose connection or internal body crack. We trace the symptom to the specific cause before recommending any solution.
InSinkErator models use a 1/4-inch Allen wrench at the center bottom; Waste King models use a broom-handle approach at the top. Knowing which you have before arriving saves time and prevents the wrong tool damaging the motor shaft.
A disposal that jams once is worth clearing and resetting. A disposal that jams repeatedly, has a seized turntable bearing, emits burning smells, or is over 10 years old is likely approaching motor failure โ and the repair cost of a failed motor exceeds the cost of a new unit.
A disposal installed without properly removing the dishwasher drain knockout plug is a common installation error that floods the dishwasher interior. We check this and correct it if present.
Most disposal calls complete in 30โ60 minutes โ same visit, flat-rate pricing.
If the jam-clearing wrench won't budge the impeller, the motor shaft may be seized rather than just stuck from debris โ we distinguish between the two before recommending replacement.
If power is confirmed at the disposal and it still won't start after a reset, the motor is failed. We then move to the replacement conversation with honest cost comparison.
Disposal leaks come from three locations: the sink flange (top of the unit where it mounts to the sink drain opening โ repaired by re-sealing the flange with plumber's putty and re-tightening the mounting ring), the side port (dishwasher drain hose connection โ usually a loose hose clamp or cracked fitting), or the bottom of the unit (internal body crack or failed internal seal โ indicates replacement needed).
An unusually loud grinding, rattling, or metal-on-metal sound from a disposal almost always means either a hard object (bottle cap, small utensil, pit from stone fruit) is in the grinding chamber, or an impeller piece has broken and is contacting the shredder ring. We access the grinding chamber safely, remove any foreign objects, and inspect the impeller and shredder ring for damage.
If the slow drain persists after cleaning the drain arm and p-trap, a camera scope of the kitchen drain line is the next step to check for blockage further downstream.
Replacement includes: safely disconnecting electrical at the junction box under the sink, removing the old unit and mounting assembly, installing the new unit with correct wiring and plumbing connections, testing for full jam-free operation, and verifying zero leaks at all connections before leaving.
No guesswork โ we diagnose before we quote, and quote before we start.
Hums but won't spin, completely silent, grinding noise, leaking, or slow to drain โ each symptom tells our dispatcher which tools and possible replacement units to have on the truck. Knowing the disposal brand is a plus but not required.
For leaks, we dry the area completely and run a short test cycle to confirm exactly which connection is dripping.
You receive a flat-rate price for the repair option and, if relevant, the replacement option with unit cost included. For a simple jam clear, that's a single, low line item. For a failed motor, we show you the new unit cost and installation price together.
After repair or replacement, we run the disposal through a full test: several cycles with water running, check under the sink for any drip at all connection points, and confirm the drain arm clears at a normal rate.

Disposal hummed and wouldn't spin. I'd already tried the Allen wrench trick without success. Masters Plumbing Service's tech came out, worked the impeller free from underneath while removing a piece of broken ceramic that had fallen in โ it had wedged between the impeller and the grinding ring in a way I couldn't have cleared from the top. Cleared the jam, pressed the reset, tested. Five-minute fix. Honest about the call minimum charge, no attempt to upsell a replacement on a perfectly good motor.
After we added a dishwasher, it started backing up every cycle. Masters Plumbing Service found the problem immediately โ the previous installer had forgotten to knock out the dishwasher drain plug inside the disposal inlet. The plug was blocking the drain port. Two-minute fix. The tech also tightened the dishwasher drain hose clamp, which was loose. Never had another backup.
Disposal leaking from the sink collar area. Previous owner had installed it with silicone instead of plumber's putty at the flange โ silicone doesn't hold the mounting pressure correctly and had separated. Tech re-seated the flange with putty, re-tightened the mounting ring, and the leak stopped. Tested with a full minute of running water. All clear.
