Viessmann Vitocal fault codes
What each code means, in plain engineer English — and which UK models it applies to, taken from Viessmann Vitocal's own service literature. Anyone can tell you what a code stands for; the model list is the part that took the manuals.

Knowing the code is the easy half
A code names a symptom, not a root cause. The app takes the same code and walks the fix: what to measure first, the expected values for your exact model, and a verdict that tells you when the machine isn't actually broken.
