No. A shared basket diameter does not guarantee the same ear geometry or locking fit. Confirm that your machine uses a compatible 58mm E61-style portafilter before ordering. Why use a bottomless portafilter? It exposes the basket underside so you can observe extraction and spot signs of uneven puck preparation. Why does espresso spray during extraction? Spraying often points to uneven flow through the puck. Review distribution, tamp level, grind, dose, and basket cleanliness before the next shot. Does natural walnut look identical on every handle? No. Natural wood can vary slightly in grain, shade, and pattern, making each handle visually distinct. How should I clean the wood handle? Wipe it with a lightly damp cloth and dry promptly. Do not soak it, use abrasive cleaners, or put the portafilter in a dishwasher. Get more from your coffee gear Check E61 fit and use bott
