Not Brewing: Causes & Fixes
A machine that won't brew has different real causes depending on whether it's a pump-driven espresso machine, a capsule machine, or a stovetop moka pot — the guides below break it down by machine type rather than guessing at one universal fix.
- Breville Espresso Machine Troubleshooting Breville's own documented fixes for descaling, no crema, water flow, grinder, and steam wand problems, centered on the Barista Express with notes on what's different for the Bambino and Oracle.
- Jura Espresso Machine Troubleshooting Jura's own documented fixes for descaling, the CLEARYL filter system, grinder noise, brewing problems, and the milk frother, sourced from Jura's E6 manual and support pages.
- Nespresso Machine Not Working: Every Fix by Error Light Real Nespresso-documented fixes for power issues, stuck capsules, brewing failures, and leaks, plus what the blinking lights actually mean on both OriginalLine and Vertuo machines.
- Keurig Coffee Maker Troubleshooting Keurig's own documented fix for a short or incomplete brew, the real descaling frequency, and what to do about grounds in your cup.
- De'Longhi Espresso Machine Troubleshooting De'Longhi makes two genuinely different machine types, automatic bean-to-cup and manual lever, with different problems and different fixes. This guide covers both separately, sourced from De'Longhi's own manuals and support pages.
- Moka Pot Troubleshooting A moka pot has no pump, no motor, and no 9-bar extraction curve, so almost none of the causes in our espresso-machine guides apply. Bialetti's own documentation covers leaking, stalled brews, and a genuinely different cause of bitter coffee.
