With average water, every 6-8 weeks is a good interval. If you notice jerky flow or poor crema, anticipate. A good practical indicator is the number of extractions: every 80-120 coffees do a complete descaling. If you use very hard water (&gt;14 \u00b0dH), consider a filter or switch to water with TDS 80-120 ppm to lengthen intervals.    <\/p>\n\n<h3 class=\"wp-block-heading alignfull\">Can I use vinegar for descaling?<\/h3>\n\n<p>Best to avoid: it can leave odors and is not designed for internal alloys. Prefer <strong>food-grade descaling agents<\/strong> that are compatible with your machine. Dedicated products dissolve limescale without attacking gaskets and metals and rinse more easily. In addition, acetic acid can impregnate plastics and the tank-the residual odor alters the in-cup profile even after multiple rinses.   <\/p>\n\n<h3 class=\"wp-block-heading alignfull\">After descaling, the coffee tastes &#8220;weird&#8221;<\/h3>\n\n<p>Do at least <strong>two tank<\/strong> rinses and 2-3 vacuum extractions. If it persists, disassemble and rewash tank and drip tray. Also check the hand shower: detergent residue or dislodged limestone can retain odors. If you have been using highly chlorinated water, try a top-up with medium TDS water (80-120 ppm) and repeat a flush cycle.   <\/p>\n\n<h3 class=\"wp-block-heading alignfull\">Do waffles affect maintenance?<\/h3>\n\n<p>Yes. Intact single-serving pouches and uncrushed pods reduce residue and clogging. Avoid waffles that are misshapen or have damaged paper: they can leak ground into the unit and dirty the hand shower and seals. Store pods away from heat and humidity: oxidized oils leave patinas that are harder to remove.   <\/p>\n\n<h3 class=\"wp-block-heading alignfull\">I followed everything but the yield is still uneven<\/h3>\n\n<p>Check the <strong>actual volume in the cup<\/strong> (measure it): variations of 5-10 ml change a lot of cream and intensity. If the pump is very noisy or flow remains abnormal, consider a service overhaul (valves\/seals). Finally, try a &#8220;fresh&#8221; reference wafer to rule out stock problems.  <\/p>\n","protected":false},"excerpt":{"rendered":"<p>After weeks of &#8220;no-stop&#8221; coffee, the output of pod machines can drop: uneven crema, erratic flow, dull aromas.
