Your NEO Flex comes with a red [Flow Control 2 Portafilter.](https://flairespresso.com/product/flow-control-2-portafiler/) If you believe a clog is present, attempt the following: First, fill the portafilter with off-boil water and leave for 1-2 minutes. Carefully empty and leave the portafilter and spout (separated) upside down to dry overnight. Next, attempt a cool, water-only shot with your complete NEO Flex placed on a bodyweight scale to monitor your force application: Do not exceed 40-50 lbs of force applied to the lever. Do not use coffee grounds or your dispersion screen during this test.  This should remove any loosened residue. If a smooth flow is achieved, proceed with a coarser grind size to prevent a repeat clog, and enjoy! If you are still unable to achieve a smooth flow after this procedure, remove your spout (which houses the Flow Control properties) and try another water-only shot. If you are now able to achieve a smooth flow, you know the clog is isolated to your spout and you will need to snag and swap in a replacement spout [here](https://flairespresso.com/product/flow-control-spout-kit/) to get back to brewing. If you are unable to achieve a smooth flow at this weight application, *with the spout removed*, carefully terminate your attempt by slowly releasing the lever and [contact us](https://flairespresso.com/contact/?__hstc=233546881.4b0367aca4ddae800dfef9f5eafbbfdf.1649620184124.1661214670469.1661221544934.31&__hssc=233546881.1.1661221544934&__hsfp=2541766894) for potential replacement routes/next steps. The basket itself, while rare, may be clogged beyond remedy.  Note a coarser grind size should always be used with the Flow Control Portafilter, to prevent clogs/build-up and to allow its properties to work without being compounded too much. Target a grind size similar to the consistency of kosher salt.  flairespresso.com Help Center - [Go to flairespresso.com](https://flairespresso.com) - [Contact us](https://support.flairespresso.com/knowledge/kb-tickets/new)
