<span class=sr-only>Link to heading</span></a></h4><p>The Breville Barista Pro has two distinct, automated maintenance procedures: the <strong>Cleaning (Flush) Cycle</strong> and the <strong>Descale Cycle</strong>. It is important to understand that these are not interchangeable, as they address different types of buildup within the machine.</p><ul><li><strong>Cleaning Cycle (Flush):</strong> This process is designed to remove coffee oils and granulated residue from the group head, shower screen, and portafilter system.</li><li><strong>Descale Cycle:</strong> This process targets the internal components of the machine, such as the thermocoil and water lines, to remove mineral and limescale deposits from water.</li></ul><h4 id=procedure-1-the-cleaning-flush-cycle><strong>Procedure 1: The Cleaning (Flush) Cycle</strong>

<a class=heading-link href=#procedure-1-the-cleaning-flush-cycle><i class="fa-solid fa-link" aria-hidden=true title="Link to heading"></i>
|
|
<span class=sr-only>Link to heading</span></a></h4><p>The machine will indicate when a cleaning cycle is needed by displaying a “FLUSH” alert on the LCD screen. This typically occurs after approximately 200 extractions.</p><p><strong>Required Materials:</strong></p><ul><li>1-Cup filter basket</li><li>Grey silicone cleaning disc (provided with the machine)</li><li>One cleaning tablet</li></ul><p><strong>Step-by-Step Instructions:</strong></p><ol><li>Insert the 1-cup filter basket into the portafilter.</li><li>Place the grey silicone cleaning disc inside the basket.</li><li>Position one cleaning tablet in the center of the disc.</li><li>Lock the portafilter firmly into the group head.</li><li>Ensure the drip tray is empty and the water tank is filled.</li><li>Press the ‘MENU’ button and use the ‘Grind Amount’ dial to navigate to the ‘FLUSH’ option. Press the dial to select it.</li><li>The ‘1 CUP’ button will illuminate. Press it to initiate the cycle.</li><li>The cleaning process will last approximately five minutes, with the machine backflushing water under pressure. The remaining time will be displayed on the screen.</li><li>Upon completion, the machine will beep and return to its ready state.</li><li>Remove the portafilter and discard the water and dissolved tablet residue. Thoroughly rinse the portafilter, cleaning disc, and filter basket.</li><li>Re-insert the portafilter (without the disc or tablet) and run a shot of hot water through the group head to rinse any remaining cleaning solution.</li></ol><h4 id=procedure-2-the-descale-cycle><strong>Procedure 2: The Descale Cycle</strong>

<a class=heading-link href=#procedure-2-the-descale-cycle><i class="fa-solid fa-link" aria-hidden=true title="Link to heading"></i>
|
|
<span class=sr-only>Link to heading</span></a></h4><p>The machine will alert you when descaling is required. The frequency depends on water hardness and usage but is generally recommended every 2-3 months.</p><p><strong>Required Materials:</strong></p><ul><li>Breville-recommended descaling solution</li><li>A large container (minimum 2-liter capacity)</li></ul><p><strong>Step-by-Step Instructions:</strong></p><p><strong>Part A: Preparation</strong></p><ol><li>Empty the drip tray and re-insert it.</li><li>Remove the water filter from the water tank.</li><li>Pour the descaling solution into the empty water tank and add fresh water up to the indicated “DESCALE” line.</li><li>Place a large container under the group head, hot water outlet, and steam wand.</li></ol><p><strong>Part B: The Descaling Process</strong></p><ol><li>Turn the machine on and press the ‘MENU’ button. Navigate to the ‘DESCALE’ option and select it by pressing the dial.</li><li>Press the illuminated ‘1 CUP’ button to begin.</li><li>The cycle proceeds in three stages. You must manually advance through them using the steam dial based on the LCD prompts:<ul><li><strong>Group Head (d3):</strong> The machine descales the coffee brewing components.</li><li><strong>Hot Water (d2):</strong> After a beep, the LCD shows “d2”. Turn the steam dial to the hot water position.</li><li><strong>Steam (d1):</strong> After another beep, the display reads “d1”. Turn the dial to the steam position.</li></ul></li></ol><p><strong>Part C: The Rinse Cycle</strong></p><ol><li>Once the descaling solution is expended, the machine will beep and prompt for a rinse cycle (“r”).</li><li>Empty the large container and rinse the water tank thoroughly.</li><li>Fill the water tank with fresh, cold water to the MAX line and re-insert it.</li><li>Place the empty container back under the outlets and press the ‘1 CUP’ button.</li><li>The rinse cycle will mirror the descaling process, prompting you to engage the group head (“r3”), hot water (“r2”), and steam wand (“r1”) in sequence.</li><li>After the rinse is complete, the machine will exit the maintenance mode and return to its ready state.</li></ol><h4 id=routine-and-preventative-maintenance-schedule><strong>Routine and Preventative Maintenance Schedule</strong>

<span class=sr-only>Link to heading</span></a></h4><p>In addition to the automated cycles, regular manual cleaning is essential for machine health.</p><p><strong>Daily Tasks:</strong></p><ul><li><strong>Purge Group Head:</strong> After the final use of the day, run hot water through the group head (without the portafilter) to clear grounds.</li><li><strong>Clean Portafilter & Baskets:</strong> Do not let used coffee grounds sit in the portafilter. Rinse with hot water after every use.</li><li><strong>Clean Steam Wand:</strong> Immediately after texturing milk, wipe the wand with a damp cloth and purge steam for 2-3 seconds to clear internal passages.</li><li><strong>Empty Drip Tray:</strong> Empty and rinse the drip tray regularly.</li></ul><p><strong>Weekly Tasks:</strong></p><ul><li><strong>Soak Components:</strong> Remove the filter basket from the portafilter. Soak both components in a solution of hot water and a cleaning tablet (or specific espresso cleaner) for 20-30 minutes to dissolve accumulated coffee oils. Rinse thoroughly.</li><li><strong>Clean Grinder:</strong> Empty the bean hopper. Run the grinder to clear any remaining beans, then use a brush and/or vacuum to clean out fines and oil residue from the burrs and chute.</li></ul><p><strong>Periodic Tasks (Every 2-3 Months):</strong></p><ul><li><strong>Replace Water Filter:</strong> The water filter located inside the water tank should be replaced every 3 months. This reduces the rate of scale buildup.</li><li><strong>Inspect Shower Screen:</strong> Use a brush to gently scrub the shower screen inside the group head to remove any stubborn coffee grounds.</li></ul><p>By adhering to this comprehensive maintenance schedule, you can ensure your Breville Barista Pro operates at peak performance and consistently produces high-quality espresso.</p><hr><p><strong>Reference:</strong></p><ul><li>Breville Barista Pro Instruction Manual and official manufacturer guidelines.</li></ul></div><footer><div id=disqus_thread></div><script>window.disqus_config=function(){},function(){if(["localhost","127.0.0.1"].indexOf(window.location.hostname)!=-1){document.getElementById("disqus_thread").innerHTML="Disqus comments not available by default when the website is previewed locally.";return}var t=document,e=t.createElement("script");e.async=!0,e.src="//ericxliu-me.disqus.com/embed.js",e.setAttribute("data-timestamp",+new Date),(t.head||t.body).appendChild(e)}(),document.addEventListener("themeChanged",function(){document.readyState=="complete"&&DISQUS.reset({reload:!0,config:disqus_config})})</script></footer></article><link rel=stylesheet href=https://cdn.jsdelivr.net/npm/katex@0.16.4/dist/katex.min.css integrity=sha384-vKruj+a13U8yHIkAyGgK1J3ArTLzrFGBbBc0tDp4ad/EyewESeXE/Iv67Aj8gKZ0 crossorigin=anonymous><script defer src=https://cdn.jsdelivr.net/npm/katex@0.16.4/dist/katex.min.js integrity=sha384-PwRUT/YqbnEjkZO0zZxNqcxACrXe+j766U2amXcgMg5457rve2Y7I6ZJSm2A0mS4 crossorigin=anonymous></script><script defer src=https://cdn.jsdelivr.net/npm/katex@0.16.4/dist/contrib/auto-render.min.js integrity=sha384-+VBxd3r6XgURycqtZ117nYw44OOcIax56Z4dCRWbxyPt0Koah1uHoK0o4+/RRE05 crossorigin=anonymous onload='renderMathInElement(document.body,{delimiters:[{left:"$$",right:"$$",display:!0},{left:"$",right:"$",display:!1},{left:"\\(",right:"\\)",display:!1},{left:"\\[",right:"\\]",display:!0}]})'></script></section></div><footer class=footer><section class=container>©
