Fault-Finding Method for Medical Equipment
How senior engineers find the fault faster
A sterilizer that aborts with a vacuum error and turns out to have a flat backup battery. A CT detector that reboots at random while seven good boards are replaced. A test that fails because the wrong test bag was used. Most lost hours in service are not lost on hard faults; they are lost on guessing. This course teaches the loop that experienced engineers run in their heads on every job: collect the facts, list the hypotheses, choose the cheapest test that separates them, measure instead of assuming, find the root cause, and return the machine to service safely with a report that the next engineer can use. Every lesson is built on real resolved cases from MRI, CT, X-ray, ultrasound, laboratory, sterilization, dental, anaesthesia and ventilation equipment.
The error code tells you where the machine noticed the problem. It rarely tells you where the problem is.
- Engineers replace parts until the error goes away, and the parts budget, the downtime and the clinic's trust pay for it.
- An error code or a colleague's 'it is always this part' sends the search in the wrong direction, and nobody checks the power, the cable or what changed last week.
- The fault comes back a month later because the part was replaced but the cause was never found, and there is no record of what was tried.
After the course you can
Curriculum
Run the senior engineer's loop on any fault — symptom, hypotheses, cheapest discriminating test, result — and recognise when experience or an error code is leading you to the wrong part.free
20 min02Collecting the facts before you touch the machine
Gather the facts that decide most faults — the user's account, a reproduction, the logs, what changed, the environment and the as-found state — before opening a cover or swapping a part.22 min03Narrowing down: signal path, half-split and substitution
Narrow a fault to one block by following the signal path, splitting it in half, substituting parts safely, comparing with known-good references and measuring rather than assuming — including faults that come and go.22 min04Power, cables and connectors first
Check supply, batteries, earth, cables, connectors and cooling first on any machine, and recognise the many errors that look like board or sensor faults but are really one of these.22 min05Root cause and records
Go beyond the failed part to the root cause with 5 whys and cause-and-effect thinking, recognise recurring faults, write a service report the next engineer can use and build your own case library.22 min06Return to service and communication
Return a repaired machine to service safely — verification, electrical safety tests and records — explain the outcome to the user and the manager, and know when and how to escalate to the manufacturer.22 min—Exam

The certificate
Pass the exam and get a certificate of course completion with your name, hours and score. Every certificate has a unique number and a public verification page, so an employer or a customer can check it in one click. It confirms completion of the course; it is not an educational document (diploma) and not a manufacturer authorisation.
Who it is for
Who it is for
- New service engineers who know the equipment but not yet a method for finding faults
- Experienced field engineers who want to work faster and explain their decisions
- Hospital biomedical / clinical engineering staff who handle first-line faults and decide when to call the manufacturer
Who teaches
Written by a service engineer working with medical equipment since 2014, including 6.5 years at GE Healthcare and service supervision at Mindray, together with the engineers of Service Engineer.
FAQ
Is this tied to one type of equipment?
No. The method holds for any equipment, and the examples come from many: MRI, CT, X-ray, ultrasound, laboratory analysers, sterilizers, dental units, anaesthesia machines, ventilators, monitors and printers.
Is this manufacturer training?
No. It is independent, vendor-neutral training. It does not replace any manufacturer's service procedures, does not grant authorisation and does not give access to service software, codes or passwords.
How does it fit with the other courses?
It is a General course. Electrical safety testing is covered in depth in the Electrical Safety course, board-level repair in Electronics, gas systems in Pneumatics and the underlying physics in Physics. This course is the method that connects them.
What does the certificate say?
Your name, the course, the hours, the date and your exam score, with a unique number and a public verification page.
Can my company buy seats for a team?
Yes: five seats and a progress overview for the manager.
