A garbage disposal is a small motor and a grind chamber under the sink, and its faults are few and recognizable. It hums but does not turn, it will not do anything at all, it leaks, or it drains slowly. Most of those are repairs, and knowing which is which saves replacing a unit that only needed clearing.
The work is either fixing what is there or fitting a new one. A jam or a reset are quick repairs; a leaking or burned-out unit is a replacement, done in the same visit while the plumbing under the sink is open.
Jammed, dead or leaking
A disposal that hums without turning is jammed, something is caught between the impellers, and forcing it just burns the motor. Clearing the jam and resetting the unit usually brings it straight back. A unit that does nothing at all is often just the reset button, which trips on overload and is the first thing to check.
Leaks tell you where the problem is. A leak at the top means the sink flange seal has failed; a leak underneath points at the unit body or a connection. A body leak on an older disposal is a replacement, while a flange or connection leak is a reseal, and telling them apart is the diagnosis.
Disposal problems and what they mean
- A hum with no grinding, the unit is jammed
- No response at all, often a tripped reset
- Water leaking from the top or underneath
- Draining slowly or backing up into the sink
- Loud rattling that points to a loose part

A disposal visit
Diagnose the fault
A hum, silence and a leak each point somewhere different.
Clear or reset first
Many dead disposals are simply jammed or tripped, not finished.
Replace when it is done
A body leak or a burned motor is a clean swap while the sink is open.
Fitting a new one properly
A new disposal is a straightforward install that goes wrong in small ways, a flange not sealed, a drain connection not aligned, a dishwasher inlet knockout forgotten so the dishwasher will not drain. Fitting it properly the first time is what keeps a new unit from leaking on day two.
It is also a good moment to check what feeds it. The sink drain, the trap and the shutoff are all right there, and catching a weeping connection or a tired trap while the disposal is out is easier than coming back for it.
Renton garbage disposal repair & installation questions
My disposal hums but will not turn. Is it dead?
Usually not, it is jammed. Something is caught between the impellers, and forcing it burns the motor. Clearing the jam and pressing the reset button typically brings it back, which is why that is checked before any talk of replacement.
The disposal does nothing at all. What first?
Check the reset button on the bottom of the unit, which trips on overload and is the most common cause of a dead disposal. If resetting does not revive it, the motor may be finished, which is a replacement.
Where is the leak coming from?
A leak at the top is the sink flange seal, which is a reseal. A leak underneath is the unit body or a connection, and a body leak on an older disposal means replacement. Locating it decides which.
Can you install a disposal I bought?
Yes. A customer-supplied unit is fitted, sealed and connected, with the dishwasher inlet handled if there is one, and the drain and shutoff checked while the sink is open.
What size disposal should I get when replacing one?
Match it to the household and the drain it feeds rather than defaulting to the biggest available. A busier kitchen benefits from more motor power and a better grind, while a modest household is well served by a mid-range unit. Just as important is the install itself, a properly sealed mounting flange, a drain connection that lines up, and the dishwasher inlet opened where needed, since those small details are what keep a new unit from leaking or backing up on the first day.

Since the visit is already under the sink, a dripping tap is worth folding in as faucet repair and installation.
