Record the slow-brew condition Stop delivery, allow the holder to cool and unplug before hands-on inspection. Record whether the filter has visible residue and whether the dose appears overfilled. Look for: These are observed starting conditions, not a diagnosis of an internal pump. Source: dedica-manual, p13 §14; p10 §11 [ ] 2. Restore the filter openings If the filter or holder spout holes are dirty, complete Clean the coffee filters. Check the perforated insert is present and fully seated before the next brew. Look for: The removable filter path is visibly clear and correctly assembled. Source: dedica-manual, p10 §11.2; p13 §14 [ ] 3. Review spout maintenance Check the coffee count since the last spout rinse. If 200 coffees have been made, use Rinse the coffee spouts for the about-0.5-litre water delivery. If normal water delivery is absent, stop and use the no-coffee check instead. Look for: The spout rinse is completed if due, or recorded as not due; an absent flow is not repeatedly forced. Source: dedica-manual, p10 §11.3; p13 §14 [ ] 4. Change the relevant preparation For the comparison brew, reduce an excessive dose or overly firm tamping and use coffee intended for espresso machines. Replace excessively fine or damp grounds. Keep the same correct one- or two-cup filter so you can describe what changed. Look for: Record the actual preparation change; do not claim an exact universal dose or pressure. Source: dedica-manual, pp6–7 §4; p13 §14 [ ] 5. Observe one normal brew Reassemble, wait for steady coffee-ready lights and brew into a cup using the normal coffee button. Keep the holder attached throughout delivery. Look for: Record whether the flow improved, stayed slow or became absent. Source: dedica-manual, p7 §4; p13 §14 [ ] 6. Route a persistent symptom If slow delivery remains, save the result. Limescale is another manual-listed cause; follow the complete indicated descaling path or contact Customer Services. No internal adjustment is included. Look for: A continued symptom stays visible in the record instead of being marked repaired. Source: dedica-manual, p13 §14; pp10–11 §12 OBSERVATIONS Visible filter or dose condition (required): ____________________ Coffee-spout rinse status (required): ____________________ Choices: Due rinse completed / Fewer than 200 coffees since rinse / Count unknown; maintenance review recorded Preparation changed for the comparison brew (required): ____________________ Observed flow (required): ____________________ Choices: Improved / Still slow [further care/preparation needed] / No delivery; further help needed [service required] RESULT CHECKS [ ] Accessible filter cleaning and spout-rinse status are recorded. [ ] The preparation change and observed brew result are recorded, with unresolved flow routed onward. NEXT CARE Coffee is delivered very slowly. Repeat the check if this symptom returns. Any reminder date is your own plan; the manual gives no scheduled interval for this check. Basis: user-plan Source: dedica-manual, p13 §14 Record preparation, maintenance readiness, problem located or service needed. This is not proof of a physical repair.
