Before buying cleaning discs

Does any 58mm cleaning disc fit the KitchenAid KES6503?

No. The nominal size is only the first check. Model-specific locking geometry, basket depth, mounting pattern, or clearance may also matter. This machine uses a KitchenAid-58 portafilter ear/lug family, which has no established third-party aftermarket. Correct 58mm diameter alone does NOT guarantee the ears/lugs will lock into this group. Verify portafilter ear/lug compatibility with the KES6503 specifically before buying any bottomless or spouted portafilter.

Is a cleaning disc the first upgrade to buy?

Not automatically. The KitchenAid KES6503's stored upgrade order starts with filter basket; fix grinder, basket, dose, or maintenance issues before adding optional tools.
