Costly or dangerous
Machine dead just after the 2-year warranty; pump and gasket swap did not help (EC685)
A certified owner reports the EC685 died overnight just after the 2-year warranty: all three buttons flash, no noise, no heat, no water from steam wand or filter, and replacing the pump and gasket changed nothing.
What to check. When the machine dies with all three lights flashing and a pump/gasket swap does not help, the fault is likely the control electronics, not the pump. This typically happens just after the 2-year warranty, so the repair is out of pocket.
Recurring descaling error that never completes, four service visits (EC685M)
The owner reports a descaling error that never completes, recurring about every two months, requiring four service visits.
What to check. In hard-water markets (Turkey) the descaling cycle repeatedly fails and the machine keeps going back to service. Use the official descaler and soft water, and be aware the recurring fault may not be resolved under warranty.
Filter basket sticks inside the machine and cannot be removed (EC685M)
The owner reports the filter basket sticks when locked into the machine and cannot be removed normally, requiring 3–4 service visits. A parallel Portuguese Deco Proteste complaint describes the same stuck-basket fault on the EC685M.
What to check. The portafilter/basket sticking is reported across markets (Turkey and Portugal) on the EC685M, and service often cannot resolve it. If it happens, push for replacement rather than repeated repairs.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
