Error code C1 displayed on your AEG, Electrolux, or Quelle-Privileg oven indicates a specific condition that must be addressed before initiating the high-temperature pyrolytic cleaning cycle.
This particular fault code, C1, signals that the oven’s internal safety monitoring system has detected the presence of metallic components that are incompatible with the extreme temperatures reached during the pyrolytic self-cleaning process. Specifically, this error means that the telescopic runners (or tray guides) are still installed inside the oven cavity when the cleaning cycle is initiated or detected.
The telescopic runners are designed for easy sliding of heavy trays and are typically constructed from materials that, while robust for normal cooking, are not rated to withstand the intense heat (often exceeding 450°C or 850°F) of pyrolysis.
To clear the C1 error code and ensure safe, effective operation of the self-cleaning feature, you must physically remove the affected parts:
Why this is Crucial: Failure to remove these runners prevents the pyrolytic cleaning from working optimally and, more importantly, prevents damage to the runners themselves. At pyrolytic temperatures, these parts can warp, discolor, seize up, or potentially damage the oven liners they slide against, leading to costly repairs or rendering the runners unusable even after the cycle completes.
