Documented faults
- DeWalt DW733
Thicknesser cuts out mid-job and the switch won't restart the motor until you find and press a reset button
The built-in motor-overload circuit breaker in the On/Off switch has tripped — usually from taking too heavy a cut, feeding too fast, or starting the cut with the workpiece already touching the cutterhead — and is protecting the motor rather than failing
Motor & Drive 2026-09-28 - DeWalt DWS780
The blade carries on spinning for longer than usual after the trigger is released, instead of being stopped quickly by the saw's automatic electric brake
A delay in brake engagement, which DeWalt's own manual says can happen occasionally and is cleared by cycling the switch — or, if it persists, worn motor brushes losing the contact the brake circuit depends on
Motor & Drive 2026-08-31 - Numatic HVR200
Henry vacuum suddenly cuts out mid-clean and won't switch back on, even though it was working normally moments before
The motor's thermal overload cutout has tripped because of restricted airflow — a safety feature, not a failed motor — and it won't reset until the blockage is cleared and the motor cools down
Motor & Drive 2026-07-11 - Stihl MS 250
Chainsaw won't start or is extremely hard to start, even though fuel is reaching the carburettor, the air filter is clean, and the spark plug is confirmed sparking
A carbon-clogged spark arrester screen in the muffler restricting exhaust flow enough to stop the engine drawing a fresh charge — an exhaust-side blockage that mimics an ignition or carburettor fault even though fuel, air, and spark all individually check out
Motor & Drive 2026-07-11 - Triton TPT125
Thicknesser motor sparks heavily at the brushes, loses power under load, and smells of ozone
Burnt or scored commutator segments causing arcing at the brush contact faces
Motor & Drive 2026-06-28 - Axminster AW106PT2
Planer/jointer hums loudly at switch-on but won't start, trips the breaker after a few seconds
Failed start capacitor or motor winding preventing the induction motor from developing starting torque
Motor & Drive 2026-06-15 - Bosch GWS 7-115
Angle grinder won't start, starts only after a jiggle or tap, or cuts out intermittently during use
Carbon brushes worn to their limit — the motor loses contact with the commutator, first intermittently, then completely
