A dead garbage disposal is one of the most common calls we get in Addison kitchens — and 6 out of 7 times, it is a 5-minute DIY fix with no tools. Work this list in order. If step 1 fixes it, you are done.
Step 1: Check that the switch and the outlet are both live
Flip the switch. Nothing? Open the cabinet under the sink. Most garbage disposals in Addison homes are plugged into an outlet inside the cabinet (not hard-wired). Make sure the plug is firmly seated.
If the outlet has a built-in reset button (red or black), press it. If the outlet is on a GFCI circuit upstream, find the nearest GFCI (usually a kitchen counter outlet) and press its reset button.
Step 2: Press the disposal's own reset button
Every garbage disposal has a reset button on the bottom of the unit — a small red or black button that pops out when the motor overheats.
Reach under the sink to the bottom of the disposal (the round black "can"), locate the reset button, and press it firmly. If it clicks and stays in, flip the switch again — most disposals come back to life immediately.
If the reset button pops right back out when you press the switch, there is a jam (Step 3) or a dead motor (Step 7).
Step 3: Clear a jam with the hex key (hums-but-does-not-spin)
If the disposal hums when you flip the switch but doesn't spin, the impellers are jammed. DO NOT keep flipping the switch — you will burn out the motor in under 30 seconds.
Every disposal ships with a small hex key (allen wrench) — usually ¼ inch, usually taped to the side of the unit under the sink. If you cannot find yours, any ¼-inch allen wrench works.
- Turn off the switch AND unplug the disposal (safety first — the impellers are sharp)
- Insert the hex key into the hole in the dead center of the bottom of the disposal
- Rotate the key back and forth — you will feel the jam break free
- Plug the disposal back in, flip the switch — it should spin
If no hex-key socket at the bottom, you have an older model — use a wooden spoon handle from above (never your hand) to spin the impellers manually.
Step 4: Flush with cold water + ice cubes
Jams are often caused by food debris stuck between the impeller and the grind ring. Run cold water for 30 seconds with the disposal on. Then drop a tray of ice cubes down the disposal with the water running — the ice helps dislodge debris and sharpen the impellers.
Never run hot water through a running disposal — hot water liquefies grease, which then resolidifies in the P-trap below.
Step 5: Check the hard-wired breaker (if plug-and-outlet are fine)
Some newer Addison kitchens have the disposal hard-wired to a dedicated circuit instead of plugged in. If step 1-4 don't help, go to your main electrical panel and look for a tripped breaker labeled "Disposal" or "Kitchen GFI."
Flip the breaker fully OFF then fully ON. Try the disposal again.
Step 6: Leaking from the bottom?
A disposal that works but leaks from the bottom usually means the internal seal has failed — this is end-of-life. Replace the unit; do not try to repair.
A disposal leaking from the TOP (where it mounts to the sink) means the mounting-ring plumber's putty has dried and cracked — fixable by replacing the mounting ring putty. A plumber in Addison does this in 30 minutes.
Step 7: Totally dead, no hum, no reset, no leak
If you have done steps 1-6 and the disposal is still completely dead — no sound, no hum, no response to the reset button — the motor has failed. Common at 10+ years of age on heavy-use disposals, sooner on 1/3 HP builder-grade units.
Replacement options in Addison:
- InSinkErator — most common brand in DFW, parts widely available
- Waste King — quieter, often faster install
- Both come in 1/2, 3/4, and 1 HP — size up if you have a family of 4+
Belt Line Plumbing carries both brands on every truck for same-visit replacement. Call (831) 290-4327 — flat-rate quote before we start, with the old unit haul-away included.
Things to never put down a garbage disposal
Even a good disposal fails early if abused. See our commercial kitchen drain rules for the full list — but at home the big ones to avoid:
- Fibrous foods (celery, corn husks, artichoke leaves) — wrap around impellers
- Grease, oil, or fat — solidifies in the P-trap below
- Rice and pasta — swells and clogs the drain
- Coffee grounds and eggshells — form sludge that clogs the trap
- Bones, fruit pits, utensils — jam the impellers
- Chemical drain cleaner — damages seals
For true drain clogs downstream of the disposal, professional drain cleaning is the right call — Belt Line Plumbing clears Addison kitchen drains same-day with a flat-rate quote.

Belt Line Plumbing Co. has served the Addison area since 2007, with 412+ five-star reviews from north Dallas homeowners, property managers, and Belt Line Restaurant Row operators.
Local factors that affect the advice above: North Texas expansive clay soil drives most residential slab and sewer failures; Dallas Water Utilities supply water at 8–11 grains of hardness per gallon shortens every water heater and tankless system without a softener; and the February 2021 Winter Storm Uri freeze exposed attic supply lines across almost every 1970s–2000s Addison home. If your situation includes any of these local realities, factor them in before deciding between repair, replacement, or a preventive upgrade.
