H 4000 ovens introduced the PerfectClean surface treatment that is still used on Miele cavities, and on the H4740B it means the interior should wipe clean without caustic cleaners. That matters in service because abrasive pads and oven cleaner damage the coating permanently, and a great many of the cavities we see on this generation have been ruined that way. It is not an error but it is worth knowing before anyone reaches for a scouring pad.
