If your grind is too coarse or your tamp is uneven, a bottomless portafilter will show minor spraying or uneven flow.

If your variant does not include a basket, you can use any standard 51mm basket that fits De'Longhi machines — including the one from your original portafilter, as long as it's a 51mm size.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"homediyer-51mm-pf-faq-item\"\u003e\n\u003ch3 class=\"homediyer-51mm-pf-faq-question\"\u003e❓ How do I clean and maintain this portafilter?\u003c\/h3\u003e\n\u003cp class=\"homediyer-51mm-pf-faq-answer\"\u003eCleaning is straightforward.

Because there's no spout, \u003cstrong\u003eno coffee residue gets trapped\u003c\/strong\u003e in hard-to-reach spots. For a deeper clean, remove the basket and soak both pieces in warm water with a small amount of espresso machine cleaner once a week. Avoid abrasive scrubbers to keep the stainless steel finish looking new.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"homediyer-51mm-pf-faq-item\"\u003e\n\u003ch3 class=\"homediyer-51mm-pf-faq-question\"\u003e❓ Can I use this with a coffee scale and a taller cup?\u003c\/h3\u003e\n\u003cp class=\"homediyer-51mm-pf-faq-answer\"\u003eAbsolutely — and that's one of the biggest advantages. Without a spout restricting the space underneath, you can easily fit a \u003cstrong\u003esmall coffee scale and a taller latte glass or mug\u003c\/strong\u003e directly under the portafilter.
