4. Follow and record
Complete the checks before recording physical work. Follow steps in order.
Record the exact version and indication
Use the nameplate identification already made while the appliance was cool. Confirm EC685 without EX:4 and record that both coffee-button lights are flashing after steam use. Leave the hot frother and holder attached.
Look for: The version and trigger both match §7.3 before any control is changed.
Manual: p8 §7.3; p6 §1Prepare the water and collection path
Check there is water in the tank and put a stable heat-resistant container under the fully assembled frother. Keep hands and face away from the dispenser.
Look for: The container will collect both steam and hot water without holding it under the outlet.
Manual: p8 §7.3 first point; p6 §2Open the steam dial for cooling
Open the dial to the steam/hot-water position. Allow steam and hot water to discharge into the container. The one-cup light flashes during this cooling delivery.
Look for: The expected discharge and one-cup indication are observed; do not remove the frother or holder.
Manual: p8 §7.3 second pointWait for the documented end state
Wait until discharge stops automatically and the one-cup and two-cup lights flash, as §7.3 describes for completion of cooling. If delivery or indications do not match, close the dial and seek manual or service guidance instead of repeatedly restarting.
Look for: Automatic stop and the two coffee-light indication occur together.
Manual: p8 §7.3 third pointClose the dial
Turn the steam dial back to ○. Confirm coffee readiness before the next normal coffee. Move the collection container only after discharge has stopped and it can be handled safely.
Look for: The dial is closed and the cooling sequence is complete.
Manual: p8 §7.3 third point; p12 §13Keep milk cleaning separate
Complete the after-milk frother-cleaning task once it is safe to purge, switch off and cool the removable parts. If the coffee lights still will not show readiness, save the remaining indication for support.
Look for: Cooling the circuit and cleaning milk residue are both addressed by their specific instructions.
Manual: p8 §§7.2–7.3
5. Keep your result
Record what you observed. A completed checklist does not certify that equipment is repaired.
When to check again
On the base EC685, both coffee lights flash together after steam and the circuit needs cooling.
Perform the §7.3 cooling cycle only for its stated version and indication; no calendar interval is specified.
