Industrial troubleshooting training
Anyone can swap parts until the machine runs again. It's expensive, it's slow, and it burns through inventory that was never the problem. faultline101 trains the skill the plant floor actually needs: diagnosing the real fault across motors, pumps, hydraulics, pneumatics, drives, sensors, and controls — so the right part gets changed the first time.
Works with no signal — install it once and the whole course runs right at the machine, in the dead zones where the work actually happens. Every competing platform needs a connection.
Written and reviewed by a working maintenance professional — not a textbook.
Every plant has felt it: a machine goes down, and the response is to start swapping parts and hoping. A new sensor. Then a new drive. Then a new motor. Three parts later the line is running again and nobody actually knows what was wrong — which means it'll happen again.
Every minute a line is down is lost production. A technician who diagnoses the actual fault gets it running sooner than one who swaps parts one at a time hoping something sticks. Speed comes from knowing where to look, not from a bigger parts crib.
Every part changed that didn't need changing is money spent, inventory burned, and often a new problem introduced. Real diagnosis means the right part gets replaced once — not a shelf's worth of guesses.
A parts-changer knows one machine. A troubleshooter can walk up to a motor, a pump, a hydraulic press, or a control loop and reason through it. That multi-skilled diagnostic thinking is what makes a technician valuable anywhere.
How it feels to use
Every scenario runs on live gauges — temperature, current, pressure, vibration — that respond to what you check. There's no hidden "correct answer" screen. The evidence is the answer, exactly like a real callout.
Every scenario runs on real readings — temperature, current, pressure, vibration — that shift based on what the learner checks. There's no hidden "correct answer" screen; the evidence is the answer.
Guessing, replacing parts preemptively, or skipping the cheap checks docks points, the same way it costs real time and money on a shop floor. Learners feel the consequence of skipping steps.
The final exam pulls questions from every module a learner has actually completed, and won't unlock until they've done the work — not a survey people click through in ninety seconds.
Every practice session draws scenarios at random from the module's pool and shuffles the order. You can't memorise "it's always the bearing" — you have to actually diagnose, every time.
You choose what to check, in what order, and the readings respond. Chase a wrong theory and you'll see it cost you — exactly like a real callout, minus the downtime.
Every scenario tracks a score based on the choices you make and the detours you take. Beat your own best. The goal isn't a passing grade — it's the fastest correct diagnosis.
Motors, pumps, hydraulics, pneumatics, VFDs, sensors, conveyors, vibration, contactors, control loops — all in one place. Most training locks you into a single specialty like PLCs. Real maintenance work crosses all of them, and so does this.
Every module below is a fully working simulation in the trainer right now — this isn't a roadmap, it's the current library.
Give students repeated, safe reps at diagnostic reasoning before they're standing in front of real equipment under time pressure.
A structured first few weeks that builds the habit of cheapest-check-first, instead of reaching for a parts catalog on instinct.
A self-contained module you can brand, host internally, and hand to a training coordinator without standing up new infrastructure.
Works where the work is
The fault doesn't wait while you walk back to the office. Install faultline101 on your phone and the whole trainer — all 35 modules, 210 real faults — sits on the device. Open it in a basement, an MCC room, the far end of a plant with no bars, and it just works. What you complete is saved on the phone and syncs itself the moment you're back in range.
The entire course is under 200 KB — less than one photo of the panel you're standing in front of. Nothing to buffer, nothing to wait for.
New — the comic
Eighteen true shop-floor rescues, told as comics — where the machine's broke, the crew's certain, and the fault's hiding in plain sight. Funny, brutally honest, and every story sneaks the lesson in under the punchline.
No subscription trap
Every other troubleshooting platform rents you access by the month — stop paying and you lose everything, even after spending hundreds of dollars. The Full Catalog is a one-time purchase. Pay once, own all 35 modules for good, and come back to practice whenever a fault has you stumped. No recurring charge, no access that evaporates when you cancel.
Prefer ongoing updates? The optional Pro plan adds new modules as they ship — but you never have to subscribe to keep what you bought.
All prices in Canadian dollars. Checkout is handled securely by Stripe — this site never sees your card details.

Yes — each learner signs up with an email (it's quick and free for Module 1). That way their progress, scores, and certification save to their account and follow them across any device. Teams get a supervisor dashboard that tracks every technician's progress and certification in one place.
Yes. Every module is a structured entry in one content file, so adding a scenario specific to your equipment doesn't require touching the application code.
Not currently — it's generated client-side, which suits self-paced skill-building. If you need certificates that hold up for compliance purposes, that requires the Enterprise backend option.
Motors, pumps, PLC/sensor circuits, pneumatics, VFDs, hydraulics, conveyors, vibration analysis, contactors, and PID control loops — see the full list above.
The Free plan gives you Module 1 in full — all 6 scenarios, forever, no card needed. The $49 Full Catalog unlocks all 35 modules permanently. Pro ($12/mo or $99/yr) adds all future modules as they ship plus priority support. For teams, per-seat annual plans include a supervisor dashboard. All paid plans give you a real account that works across devices.
