• Kärcher K3
  

  Pressure washer runs and sprays water normally, but no detergent comes through even with a full bottle fitted

  Detergent only draws in low-pressure mode, and the tiny suction filter and hose feeding it from the bottle clog or kink easily — the machine is often not faulty, just set wrong or blocked at the pickup

  Pumps & Pressure 2026-09-29
• Axminster AP2920B
  

  Bandsaw blades keep snapping or breaking, sometimes within minutes of fitting a new one

  Axminster's own troubleshooting guide for this bandsaw names three causes for blade breakage: insufficient blade tension, misaligned blade guides, and feeding timber through too quickly — all setup issues, not a fault with the machine itself

  Blades & Alignment 2026-09-29
• Kärcher K7
  

  Pressure washer won't switch on at all, or starts and runs for a while before stopping and refusing to restart

  Usually not a fault: the motor's built-in overload breaker has tripped from a long hard run and needs an hour to cool, or the supply reaching the machine (extension lead, weak socket, wrong voltage) is too weak to start it. A damaged mains cable is the one version of this that needs attention rather than a wait

  Pumps & Pressure 2026-09-28
• 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
• Record Power Envoy
  

  The turning tool suddenly digs into the spinning workpiece or gets grabbed by it, rather than cutting smoothly

  Record Power's own manual names four specific causes, and none of them is a fault with the lathe itself: a blunt tool, the tool rest set too low, the tool rest too far back from the timber, or the wrong tool for the cut being attempted

  Blades & Alignment 2026-09-28
• Record Power DML250
  

  The DML250 mini lathe vibrates or shakes noticeably while turning, rather than running smoothly

  Record Power's own troubleshooting table names five distinct causes for lathe vibration, from a simple out-of-balance workpiece to worn spindle bearings — not one single fault

  Mechanical & Motion 2026-09-22
• Axminster AP340PD
  

  The drill bit visibly wobbles or runs noticeably out of true while spinning, instead of turning dead straight

  Axminster's own troubleshooting table for this pillar drill names four distinct causes for run-out or wobble: a bent drill bit, the bit not properly seated in the chuck, the chuck not properly seated on the spindle, and worn spindle bearings — only the last of those needs a replacement part

  Chucks & Fittings 2026-09-22
• Record Power CL4
  

  The lathe stops mid-turn and the main spindle bearing is locked solid, with no give when turned by hand

  The main spindle bearing has seized inside its race — wear, contamination or age — rather than a fault in the motor or drive belt

  Mechanical & Motion 2026-09-21
• Makita DGA408
  

  The grinder stops suddenly mid-cut with no warning, and pulling the switch trigger again does nothing

  The tool/battery protection system has tripped — overload, overheating or a near-empty battery — rather than a fault in the grinder itself; in some cases repeated tripping locks the tool until the battery is recharged

  Batteries & Charging 2026-09-21
• DeWalt DCD776
  

  The drill switches itself off mid-job with no warning and won't run again straight away

  DeWalt's Electronic Protection System has engaged to protect the XR Li-Ion battery pack against overloading, overheating or deep discharge, rather than a fault in the drill

  Batteries & Charging 2026-09-21
• Makita DUC302
  

  The chainsaw won't start — nothing happens when the switch trigger is pulled, even with a battery fitted

  Usually one of several separate start conditions rather than a fault: a missing second battery, an unreleased chain brake, the lock-off button not pressed first, or the tool/battery protection system silently blocking a start

  Batteries & Charging 2026-09-16
• DeWalt DCN660
  

  The nailer won't drive fasteners — the trigger does nothing, or it fires the motor but no nail comes out

  DeWalt splits this into distinct stages rather than one fault — trigger lock-off left engaged, a flat battery, an unreleased contact trip or mode selector, or a jam in the nosepiece or magazine — and the worklights next to the trigger indicate which

  Mechanical & Motion 2026-09-16
• Record Power DML305
  

  Turned spindles come off the lathe with a visible spiral or thread-like ridge running along them, instead of a smooth surface

  Record Power's own support answer names centre alignment first, not bearing wear — a common owner assumption their own knowledge base article directly addresses and rules against as the most likely cause

  Blades & Alignment 2026-09-16
• Makita DLM380
  

  The mower won't start — nothing happens when the switch lever is pulled, even with a battery fitted

  Almost always the start sequence or a battery/lock-key check rather than a fault — the DLM380 needs two charged batteries, the lock key fitted, and the switch button pressed before the lever is pulled

  Batteries & Charging 2026-09-15
• Record Power PT260
  

  The PT260 won't start at all — the motor doesn't run when the switch is pressed, in either planing or thicknessing mode

  One of the PT260's three safety microswitches isn't being closed by the table lock, the dust extraction hood, or the swing-over outlet — the interlock working as designed, not a fault

  Guards & Safety 2026-09-15
• Makita UC4041A
  

  The saw chain keeps moving even after the chain brake lever has been engaged

  Worn brake band inside the clutch drum, which no longer grips hard enough to stop the chain when the brake is applied

  Guards & Safety 2026-09-07
• Record Power CL2
  

  The lathe stops during turning and the main spindle bearing is locked solid, refusing to turn

  The main bearing has seized on the spindle, usually from wear or contamination inside the bearing race, rather than a fault elsewhere in the drive

  Mechanical & Motion 2026-09-07
• Bambu Lab P1S
  

  Heatbed temperature does not rise during print preparation, or the bed simply never heats after a bed temperature is set

  Either the bed's temperature sensor circuit is broken, so the printer reads nothing and never asks for heat, or the sensor is fine and the mains-side heating supply to the bed has failed

  Electronics & Firmware 2026-09-01
• Makita DC18RC
  

  Charger flashes red and green alternately when a battery is fitted, and the battery never starts charging

  Makita's own manual gives two causes for this specific pattern — contaminated terminals on the charger or the battery, or a battery cartridge that is worn out or damaged

  Batteries & Charging 2026-09-01
• Record Power CL3
  

  Too much play in the headstock spindle, with vibration that makes the lathe difficult to turn on

  Headstock bearing clearance opening up with use — on the CL3 the bearings are designed to be adjusted to take up that wear, not replaced at the first sign of movement

  Mechanical & Motion 2026-09-01
• 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
• Kärcher K2
  

  Water drips or leaks from the underside of the housing, including when the machine is switched off, sometimes alongside the motor not stopping when the trigger is released

  A failed internal seal inside the pressure-switch/cylinder-head unit at the top of the pump — a sealed, solvent-welded assembly rather than a serviceable part

  Pumps & Pressure 2026-08-29
• Prusa MK4
  

  Printer stops during Z-axis homing with "Failed to home the extruder in Z-axis, make sure the loadcell is working" and error code #13301

  Usually something adding resistance the loadcell reads as the nozzle touching the bed too early — filament drag, a binding trapezoid nut, or overtightened bolts near the sensor — rather than a failed loadcell

  Electronics & Firmware 2026-08-29
• Prusa MINI
  

  Printer stops during the initial preheat with "Preheat error print head" and error code #12202, before the print begins

  The hotend is not gaining heat at all — usually a broken or intermittent connection in the heater or thermistor wiring at the print head, rather than a failed mainboard

  Electronics & Firmware 2026-08-24
• Bambu Lab A1 Mini
  

  Print stops part-way and the printer reports 'The nozzle temperature is abnormal, the sensor may be open circuit' with HMS code 0300-0200-0001-0007

  An open circuit somewhere in the hotend's NTC temperature-sensor path — far more often a connector that has backed part-way out of the toolhead board than a genuinely failed sensor

  Electronics & Firmware 2026-08-23
• Creality Ender 3 V2
  

  Printer stops dead and the screen shows 'Err: MINTEMP' with 'Printer halted. kill() called!' — nothing responds until it is switched off and on again

  An open circuit in a temperature-sensor path — usually a thermistor lead fatigued where the hotend loom flexes — so the firmware reads an impossibly low temperature and shuts everything down; a genuinely cold workshop can trip the same limit with nothing broken

  Electronics & Firmware 2026-08-23
• Kärcher K5
  

  Pressure washer runs and passes water but never reaches full pressure, or surges and fluctuates badly, even though the motor sounds normal

  Restricted or aerated flow through the pump — a blocked high-pressure nozzle, a silted-up inlet sieve, or trapped air — rather than a worn pump; a sticking bypass valve in the pump head is the less common and more expensive cause

  Pumps & Pressure 2026-08-23
• Triton TRA001
  

  Router won't wind up and down smoothly under a table — the winder handle feels heavy or jams, and the body drops a few millimetres the moment the plunge lock is released

  Table-mode setup rather than a failed part: with the plunge return spring out, the winder lifts the machine's full weight through a rack and pinion that has several millimetres of backlash, and downward pressure on the handle racks the plunge columns and binds them

  Mechanical & Motion 2026-08-23
• Einhell TE-CD 18 Li
  

  Drill is completely unresponsive even though the battery's own charge-level LEDs show it's fully charged

  The battery isn't fully seated in the tool, or the contact points on the battery and/or tool have picked up dirt or light corrosion — the battery's charge LEDs work independently of the tool-side contacts, so a battery can genuinely show 'full' while still failing to make a working connection with the tool

  Batteries & Charging 2026-07-11
• Milwaukee 2606-20
  

  Drill appears completely dead with a fully charged battery — no lights, no response, as if the tool has failed entirely

  The tool has been remotely locked via Milwaukee's One-Key app, not a hardware fault — a locked tool looks and behaves exactly like a dead one

  Electronics & Firmware 2026-07-11
• 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
• Prusa MK3S
  

  Print aborts partway through with a THERMAL RUNAWAY error, usually right as the part-cooling fan spins up, even though the hotend was heating perfectly moments before

  The part-cooling fan is cooling the hotend heater block faster than it can compensate — usually because the silicone sock insulating the heater block is missing, worn out, or the printer's sock/no-sock setting doesn't match reality — which trips the firmware's thermal safety cutoff and looks exactly like a failed thermistor or heater cartridge

  Electronics & Firmware 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
• Bambu Lab A1
  

  Printer shows 'printing' state in the app and on the display with no job running; won't accept new jobs until power-cycled

  Stale print-job state left behind after an interrupted job or dropped cloud connection — the previous job's status is never cleared

  Electronics & Firmware 2026-07-01
• 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
• DeWalt DWS774
  

  Mitre saw cuts are out of square — 90° cuts show a visible gap against a square, and mitred frames won't close up

  Fence or bevel calibration drift — the saw's reference surfaces no longer match the scale detents, usually after transport, a knock, or dust packed behind the fence

  Blades & Alignment 2026-06-26
• Record Power BS250
  

  Bandsaw cuts wander away from the fence — the blade drifts sideways through the cut no matter how carefully the wood is fed

  A dull or unevenly-set blade, insufficient tension, or misadjusted guides — drift is almost always setup, not a machine fault

  Blades & Alignment 2026-06-22
• Bosch PST 700 E
  

  Jigsaw cuts wander off line and come out bevelled — the cut edge leans noticeably in thicker material despite the base being set square

  Blade deflection: a dull, bent, or wrong-type blade flexing sideways in the cut, often aggravated by feeding too fast or a worn blade support roller

  Blades & Alignment 2026-06-18
• 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
• Creality Ender 3
  

  Prints develop sudden sideways layer shifts partway through — the print is perfect below a line and offset above it

  Loose pulley grub screws or incorrect belt tension letting the X or Y axis lose position mid-print

  Mechanical & Motion 2026-06-14
• Makita 5704R
  

  Circular saw's lower blade guard returns slowly after a cut, hangs partway, or has to be flicked shut by hand

  Resin and compacted sawdust in the guard's pivot ring binding its rotation — occasionally a stretched or detached return spring

  Guards & Safety 2026-06-11
• Kärcher K4
  

  Pressure washer switches itself on and off repeatedly (pulsing) with the trigger released

  A small pressure leak downstream of the pump — the auto-stop system sees pressure decay and restarts the motor to top it back up

  Pumps & Pressure 2026-06-08
• 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

  Motor & Drive 2026-06-02
• Makita HR2470
  

  SDS drill still spins normally but has stopped hammering, or hammers weakly with a change in sound

  Worn or hardened O-rings in the pneumatic hammer mechanism (or dried-out grease) letting the air cushion leak away

  Mechanical & Motion 2026-05-30
• DeWalt DCF887
  

  Impact driver no longer holds bits securely — bits wobble, slip, or drop out of the chuck mid-job

  Worn bit-retention parts in the quarter-inch hex chuck — the retaining ball, spring, or sleeve no longer grip the bit's groove

  Chucks & Fittings 2026-05-26
• Ryobi ONE+ 18V
  

  Battery refuses to charge after storage — charger flashes its 'defective' pattern the moment the pack is inserted

  The battery, not the charger: deep discharge during storage has dropped the cells below the cutoff voltage the charger accepts, so it flags a healthy-but-empty pack as faulty

  Batteries & Charging 2026-05-22
