About
Every answer here was earned on the job.
Ask Dhanu is the working knowledge of Dhanushka Kariyawasam, written down so the next person can solve the same problem in seconds instead of losing a shift to it.
Practical experience
The answers come from hands-on work with the machines and systems themselves: setting them up, running them, and putting them right when they go wrong.
Validated
A fix is only written up once it has been shown to solve the problem. Each answer says how to confirm the problem is really gone.
Verified
Answers from that experience carry the “Verified in practice” mark, so you always know which ones were proven first-hand.
Two kinds of answer, clearly marked
- Verified in practice
- Dhanu's own experience: the fault, its real causes, the fix in order, the points to inspect and how to stop it coming back.
- Reference
- Useful background kept alongside for convenience — machine references and question-and-answer sets on GMP, HACCP, SQF, documentation and more. It is labelled as reference and is never presented as personal experience.
