4. Follow and record
Complete the checks before recording physical work. Follow steps in order.
Record the intended preparation
Work with the cool detached holder and unplugged appliance. Record one cup or two cups and check that the corresponding original filter C2 or C3 is fitted.
Look for: The filter choice matches the intended preparation.
Manual: p6 §§1.3,4; p13 §14Check the seated insert and clean rim
Look for a missing, raised or dirty perforated insert. Complete filter cleaning if needed and press the insert fully home. Remove loose grounds from the rim.
Look for: A clean, seated insert and clear rim are ready for a suitable dose.
Manual: p10 §11.2; p7 §4 step4Correct excess coffee
The manual lists too much coffee as the cause of a holder that cannot attach. Use the measure supplied for your machine and the correct filter; reduce excess coffee so the preparation fits. Do not substitute a guessed gram limit.
Look for: Record whether excess dose was found and reduced.
Manual: p13 §14: filter holder cannot be attachedDistribute and tamp normally
Distribute the grounds evenly and press gently with the matching tamper. Recheck the level and clear the rim again before attachment.
Look for: The prepared basket is not visibly overfilled and its rim is clear.
Manual: p6 §4 steps2–3; p7 §4 step4Try the normal attachment
Align the holder at INSERT and rotate right toward CLOSE as pictured. Record whether it attaches normally. Stop if it still resists instead of forcing the lock.
Look for: The original holder reaches its normal secure position, or the remaining fit problem is recorded for help.
Manual: p6 §3 step4; p13 §14Choose the follow-up
If attachment is normal, use the usual coffee-ready controls for the next brew and watch for any rim leak. If it still will not attach with correct parts and dose, contact Customer Services with the recorded checks.
Look for: Continued refusal to fit is not treated as permission to modify the basket, lugs or gasket.
Manual: p7 §4; p13 §14
5. Keep your result
Record what you observed. A completed checklist does not certify that equipment is repaired.
When to check again
The filter holder cannot be attached before brewing.
Repeat the check if this symptom returns. Any reminder date is your own plan; the manual gives no scheduled interval for this check.
