Miele coffee systems (CM 5510/6150, CVA 6401/6805) error codes
Miele coffee systems show F-codes from the built-in self diagnosis. The water-supply codes are user-fixable; the valve and brew-unit codes usually need Miele service.
Meanings below follow the Miele operating-instruction manuals; wording varies slightly between CM countertop and CVA built-in models.
All codes
| Code | Meaning | Fault | DIY |
|---|---|---|---|
F10 / F17 | No water, or very little water, is being drawn in — the Miele manual wording for a water-supply fault | water not drawn in | easy |
F77 | Internal fault, most often at valve initialization — the Miele manuals route it to a power cycle, then service | valve initialization fault | not recommended |
