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 Joppa, MD arrive with the jamming tools, reset wrench, and replacement units to resolve any disposal failure same visit.

Garbage disposal failures have specific, diagnosable causes. Our techs don't just swap units โ they identify what failed and whether repair or replacement is the right call for your situation.
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 isn't an isolated appliance โ it connects to the sink drain, the dishwasher drain (if present), and the drain arm leading to the p-trap. We inspect the full connection set during any disposal call: drain arm slope, dishwasher drain knockout (if a dishwasher is being added), and p-trap connection integrity.
From a simple jam clear to a full replacement with drain reconnection, here's how we handle each garbage disposal scenario in Joppa, MD.
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.
We identify the leak source before recommending any repair. A sink collar re-seal is a 30-minute job. A unit with a cracked body has no cost-effective repair and warrants replacement.
If the turntable bearing has failed โ indicated by a loud rumbling throughout operation rather than specific impact sounds โ that's an internal motor wear failure that warrants replacement.
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.
When the motor has failed, the unit body is cracked, or the existing unit is underpowered for the household's use pattern, we replace the disposal with a new unit matched to the sink drain configuration. We carry 1/2 HP, 3/4 HP, and 1 HP units from InSinkErator and other major brands on our trucks for same-day installation.
No guesswork โ we diagnose before we quote, and quote before we start.
If you know the disposal is over 10 years old, tell us โ that changes how we approach the repair-vs-replace conversation upfront.
The tech identifies the failure type in minutes: jam test at the motor socket, reset button check, power confirmation at the wire connections, leak source tracing. We know what each symptom means and we go straight to confirming it.
You decide. We don't upsell replacement when repair is the right answer, and we don't push a cheap repair that won't hold on a unit that's genuinely at end of life.
We leave the cabinet dry and the disposal running quietly. If a dishwasher drain hose was involved, we run a dishwasher cycle to verify no backup occurs.

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.
Old disposal stopped working completely โ no hum, nothing. I assumed the motor failed. The tech checked the wiring first โ found a loose wire nut at the junction box under the sink that had vibrated loose over the years. Reconnected the wire, reset the overload button, disposal came right on. Would have been embarrassing if I'd bought a replacement unit. Masters Plumbing Service's thoroughness saved me a few hundred dollars.
