How We Write and Test Guides
What goes into a guide, what counts as a test, and how we fix mistakes.
Where the information comes from
Three places: the manufacturer's manuals and service documents, fixes that owner communities have documented, and our own work on a machine where the guide says so. Each guide lists its sources in a References section at the end.
What counts as a test
A tested step names the machine, the version and what we observed. A step we haven't carried out ourselves says that it comes from a manual or from owner reports. We don't make up measurements. A product photo or a supplier specification is not a test result.
Risk levels
Every guide carries one of four levels, so you know what the job touches before you start.
- Level 0 External maintenance covered by the owner's manual.
- Level 1 Mechanical work and accessories with a documented fit for your version.
- Level 2 Internal electrical or pressure work. Needs the current kit manual and your exact machine and voltage.
- Level 3 Custom controllers and open-hardware projects.
Steps that open the case, touch mains power or hot water are flagged in the guide itself. The stop conditions are on the risk and safety section of the Mods page.
Updates and corrections
Each guide shows the date it was last updated. When a reader reports a step that didn't work, we check it against the machine version and correct the guide once the fix is confirmed.
Affiliate links
