How to describe a machine fault so an engineer can quote it

Most machine repair jobs that stall do not stall on price. They stall because the engineer cannot tell, from the description, whether the job is a two-hour sensor swap or a two-day strip and rebuild. The fix is almost always in the brief.

Start with what the machine is doing, not what you think is broken

"Hydraulic press won't build pressure" gives an engineer something to work with. "Needs a new pump" gives them a part number to argue about. Describe the behaviour: what happens, when it happens, and what changed just before it started.

• What the machine does now, in plain description.
• When it started, and whether anything changed around that time (new operator, new material, a service, a move).
• Whether it is constant or intermittent. Intermittent faults need a different plan and a different price.

Error codes and control system

If the control system shows a code, give the exact code and the control platform. A fault code is worth more than a paragraph of description because it tells an engineer which manual, which parameter set and which test routine apply.

Name the manufacturer, model family and control system where you know them. If you keep a machine record on FixMySystem, that detail is already attached to the job.

Say how much the downtime costs you

Setting the production status — running, degraded or stopped — is the single most useful thing you can add. It tells an engineer whether the repair has to happen tonight or whether it can be scheduled into a planned shutdown. It also explains why one quote might include out-of-hours rates and another does not.

State the attendance window and the site rules

An engineer pricing a job is pricing travel, access and time on site.

• The window you can actually accept someone on site.
• Site contact, and who can authorise work when they arrive.
• Access limits: gate width, lift booking, stairs, permit-to-work, escort requirements.
• Isolation: who is authorised to isolate the machine, and whether production needs to stop for it.

Putting these in the posting means the quotes you receive already include them. The alternative is a price that grows after the visit, which helps nobody.

Photos, but the useful ones

A wide shot of the machine is fine. The photos that actually help are the nameplate, the control screen showing the fault, and the area around the fault — including anything that restricts access to it.

What a good brief gets you

A brief built this way is quotable. Engineers can decide quickly whether they work on that equipment, and the quotes you get back are closer to what the job will actually cost. That is the whole point of comparing quotes rather than accepting the first number.
