What's actually causing this
Garbage disposals jam when hard items (bones, pits, silverware) get lodged between the impellers and the grinding ring. The motor overheats and trips an internal breaker.

Step-by-step fix
-
1
Turn off the disposal
Switch off the wall switch and unplug the unit under the sink, or turn off its circuit breaker. Never work on a disposal that could activate.
-
2
Press the reset button
Look for a small red or black button on the underside of the disposal. Press it firmly until you feel a click. This resets the overload protector.
-
3
Unjam the flywheel
Insert a 1/4-inch Allen wrench into the hex socket at the center bottom of the disposal. Work it back and forth until the flywheel turns freely in both directions.
-
4
Remove the obstruction
Use tongs or needle-nose pliers to remove any debris from the opening. Use a flashlight to check for items — never use your hand.

5
Test the disposal
Plug it back in, wait 15 minutes for the motor to cool, press reset again, then turn the cold water on before switching the disposal on.
In Boston, tap water is soft (30–70 ppm). Boston's water is soft, sourced from protected upland reservoirs. Mineral buildup is minimal. Soft water can cause pin-holing in copper piping, particularly in older systems. Corrosion is a concern in pre-1950s buildings.
Plumbers in Boston typically charge $145–240/hr. Most homeowners budget $800–2,500 for common repairs like fixture replacement, drain clearing, or valve repairs.
Massachusetts requires state licensing for plumbers. Boston has strict codes and inspections. Homeowner exemptions limited to minor repairs.
Pre-1950s homes dominant in urban core. Galvanized piping with severe corrosion is common. Cast-iron drain stacks are standard. Copper replacement is frequent in renovations. Soft water can cause pin-holing. Freeze-thaw cycles cause burst risk. Many homes have radiant heat systems.
DIY in Boston: Boston's strict code requirements, historic preservation rules, and high licensing standards make DIY repairs very restricted. Most homeowners must hire licensed professionals. Permits are expensive and inspections are thorough. The cost of non-compliance is high.
- The unit leaks from the bottom — the internal seals have failed.
- It runs but drains slowly — the drain line may be clogged further down.
- It makes a loud grinding or rattling noise even after clearing the jam — a bearing may be damaged.
- The unit is more than 10 years old and has had multiple issues.
