Can you inspect the cooled original filter and identify whether the coffee-spout rinse is due?
- Yes — Complete any needed cleaning before the comparison brew.
- No — Let the holder cool and compare the correct filter and maintenance history first.
- Not sure — Save a preparation record and compare the matching manual before continuing.
4. Follow and record
Complete the checks before recording physical work. Follow steps in order.
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.
Manual: p13 §14; p10 §11Restore 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.
Manual: p10 §11.2; p13 §14Review 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.
Manual: p10 §11.3; p13 §14Change 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.
Manual: pp6–7 §4; p13 §14Observe 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.
Manual: p7 §4; p13 §14Route 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.
Manual: p13 §14; pp10–11 §12
5. Keep your result
Record what you observed. A completed checklist does not certify that equipment is repaired.
When to check again
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.
