Why did shop vac stop working?
If your Craftsman 113179255 wet/dry vacuum stopped working, the most common causes are a tripped power source, a clogged filter or hose that overheats the motor, or a failed switch or cord connection. Start with power checks, then clear airflow restrictions, then test the electrical path.
Quick checks (fastest fixes first)
- Reset the outlet: try a different outlet and reset the breaker or GFCI.
- Inspect the power cord for cuts, crushed spots, or a loose plug.
- Let the vacuum cool for 20 to 30 minutes if it stopped mid-use (overheat protection can trip when airflow is blocked).
- Empty the tank; an overfilled tank can pull debris into the filter and restrict airflow.
- Remove the hose and wand; check for a clog at the inlet port and inside the hose.
Airflow problems that can shut a shop vac down
A wet/dry vacuum depends on airflow to keep the motor cool. A clogged filter, blocked hose, or packed debris at the inlet can reduce airflow enough to trigger thermal protection or make the motor sound strained.
What to do
- Clean or replace the filter if it is caked with fine dust.
- Check the hose for cracks or collapsed sections that reduce suction.
- Confirm the float (if equipped) is not stuck in the “up” position after wet pickup.
Electrical problems (when it is completely dead)
If there is no sound at all, focus on the switch, cord, and internal connections.
| Symptom | Most likely cause | Best next step |
|---|---|---|
| No lights/sound | No power, bad cord, bad switch | Verify outlet, then inspect cord and switch |
| Hums but won’t run | Jammed fan, debris in motor area | Unplug, check for obstruction at inlet and motor housing |
| Runs but no suction | Clogged filter/hose, air leak | Clear clogs, reseat lid and seals |

Why it matters
Running a shop vac with restricted airflow can repeatedly trip overheat protection and can damage the motor over time. Restoring airflow and fixing power issues prevents repeat shutdowns.
For model-specific operating and maintenance details (filter care, wet pickup setup, and safety steps), use the 113179255 owner's manual. If you need to look up replacement parts by model number, we list parts by model on our site at Sears PartsDirect.

Why do shop vacuums lose suction?
Shop vacuums (including the Craftsman 113179255 wet/dry vacuum) usually lose suction because airflow is restricted somewhere in the system: a clogged filter, a blockage in the hose or inlet, a full drum, or an air leak at the lid, hose, or seals. Use the 113179255 owner's manual for your model’s filter and maintenance steps.
Most common causes (and what to check first)
- Filter clogged or installed incorrectly: fine dust quickly plugs the filter and cuts airflow.
- Hose or wand blockage: screws, chunks of debris, or wet clumps can lodge in bends.
- Drum is full: once debris reaches the filter area, suction drops fast.
- Air leak: loose hose connection, cracked hose, or lid not sealing.
- Wrong setup for wet pickup: using a dry filter when picking up liquids can restrict flow.
Quick troubleshooting steps (10 minutes)
- Unplug the vacuum.
- Remove the hose and check for clogs; push a broom handle through if needed.
- Empty the collection drum.
- Remove the filter; tap off dust outdoors, then clean or replace it as your manual allows.
- Reinstall the filter and confirm the lid is seated and latches are tight.
- Inspect the hose for splits and the inlet for debris.
Symptom-to-cause guide
| What you notice | Most likely cause | Best next check |
|---|---|---|
| Motor sounds normal, suction weak | Clogged filter | Clean/replace filter, confirm fit |
| Suction comes and goes | Partial hose clog | Check bends, nozzle, inlet |
| High-pitched whine | Air leak | Lid seal, hose ends, cracks |
| Works briefly after emptying | Drum overfilling filter area | Empty sooner, check filter loading |
Why it matters
Low suction is almost always an airflow problem. Fixing the restriction protects the motor, improves pickup, and reduces dust blow-by that can shorten filter life.

Which is the best wet and dry vacuum cleaner?
The best wet/dry vacuum depends on where you’ll use it and what you’ll pick up. For garages, workshops, and jobsite debris, a shop-style wet/dry vacuum like the Craftsman 113179255 is the right fit. For everyday indoor hard floors, a vacuum-mop combo is usually the better choice.
Choose the right type for the job
Wet/dry cleaners generally fall into two groups; picking the right one prevents clogs, poor pickup, and unnecessary maintenance.
- Shop wet/dry vacuum: handles mixed debris (dust, chips, small hardware) and liquid pickup
- Vacuum-mop combo: designed for sealed hard floors and routine wet cleaning
- Corded vs. cordless: corded favors longer run time; cordless favors portability and quick grab-and-go use
- Tank size: larger tanks reduce emptying; smaller tanks store easier
- Filtration: fine dust work needs the correct filter and a good lid seal
Quick comparison
| If you mainly clean… | Best choice | What to prioritize |
|---|---|---|
| Garage, basement, workshop, renovation mess | Shop wet/dry vacuum (like Craftsman 113179255) | Hose diameter, tank capacity, filter type, rugged accessories |
| Kitchens, bathrooms, daily hard-floor spills | Vacuum-mop combo | Brush roll design, dirty-water tank access, drying performance |
| Occasional wet pickup only | Either type | Storage space, accessory set, ease of rinsing the tank |
What to look at before you buy
Use these practical checks to match performance to your space:
- Debris type: fine dust vs. larger debris vs. liquids
- Accessory needs: crevice tool, floor nozzle, car detailing tools
- Maintenance: how easy it is to rinse the tank, clear the hose, and clean or replace filters
- Noise and storage: where it will live and how often you’ll move it
Why it matters
A shop wet/dry vacuum is built for heavier debris and wet pickup, while a vacuum-mop combo is built for frequent indoor floor washing. Matching the tool to the mess improves cleaning speed, reduces filter plugging, and helps the vacuum last longer.
