The WKt 4551 GrandCru is a built-in wine cabinet in the GrandCru series, distinguished from the WKes and WKUes models by its own designation and cabinet configuration.
A door alarm sounding despite a closed door, and whichever F- or S-series code the panel is actually showing, are the two complaints specific to this model.
