If your machine has a removable brew unit, weekly cleaning is a good general routine for a machine used regularly at home. Remove the brewer and rinse away loose coffee grounds and residue with lukewarm water, provided this is permitted for your machine. Always follow the cleaning instructions for your specific model, as requirements vary.

Yes. The more coffee you make, the faster coffee grounds and oils can accumulate around the brewing chamber, filters and moving components. If your machine is heavily used, inspect the brewer every few days and clean it whenever you notice significant coffee residue building up.

No. They perform different jobs. Rinsing a removable brewer removes loose grounds and surface deposits, while a cleaning programme may be designed to remove coffee oils and deposits from areas you cannot reach manually. If your machine requests a cleaning cycle, don't ignore it simply because you've recently rinsed the brewer.

Look for visible coffee residue, compacted grounds or deposits around the brewer and its filters. You may also notice coffee dispensing more slowly, inconsistent coffee, unusual brewing noises or the brewer becoming more difficult to remove or operate.

Yes. Regular brewer cleaning can help prevent coffee grounds and oils from building up around filters, moving components and the brewing chamber. Excessive build-up can restrict water flow, interfere with movement and contribute to poor dispensing or interrupted brewing cycles. Keeping the brewer clean is one of the simplest preventative maintenance jobs you can do.
