- Yes — Try the documented cup-and-holder preheat.
- No — Resolve a missing ready indication or absent delivery with the matching troubleshooting route first.

4. Follow and record
Complete the checks before recording physical work. Follow steps in order.
Record the comparison conditions
Record whether the cup and holder had been preheated on the previous unsatisfactory brew. Use the same cup type and intended coffee preparation for this comparison.
Look for: The record identifies the preparation being changed without claiming a measured heater fault.
Manual: p7 §4.2Attach the empty original filter and holder
On the cooled machine, fit clean C2 or C3 in the holder with no ground coffee. Attach the holder normally and make sure the tank is seated with fresh water below MAX.
Look for: The empty filter path is ready for water-only preheating.
Manual: p7 §4.2; p6 §2Warm the holder and the same cup
Power on and wait for steady coffee-ready lights. Put the cup intended for the coffee under the spouts. Press the one-cup button B1 to deliver hot water through the empty holder into that cup.
Look for: The cup and holder are warmed by the documented one-cup delivery.
Manual: p7 §4.2Empty the water and prepare coffee safely
Wait for delivery to stop and the settling period in §4. Handle the hot cup carefully and empty the preheat water. Allow the holder to be safe to handle before detaching it for the normal coffee dose; never remove it during delivery.
Look for: No hot flow or pressurized holder is handled, and preheat water has been emptied.
Manual: p7 §§4–4.2Make the comparison brew
Prepare the correct espresso grounds and filter, refit the holder and brew into the warmed cup with the normal coffee button when ready. Record whether the drink is acceptably warm.
Look for: The observation is a comparison of this preparation, not a measured temperature certification.
Manual: pp6–7 §§4–4.2Record the next action
If preheating is insufficient, consult the brewing-temperature option in the exact §9 settings table or Customer Services. Do not infer beverage temperature from the thermoblock setting or open the heater assembly.
Look for: The manual distinguishes thermoblock water temperature from beverage temperature in the cup.
Manual: p7 §4.2; p9 §9: brewing temperature
5. Keep your result
Record what you observed. A completed checklist does not certify that equipment is repaired.
When to check again
Coffee warmth is unsatisfactory although readiness and delivery are normal.
Repeat the check if this symptom returns. Any reminder date is your own plan; the manual gives no scheduled interval for this check.
