Quick answer — E16 — commonly associated with a heating/flow issue on a ASKO coffee machine. Meaning can vary by model; verify before relying on it.
On many ASKO coffee machine models, the E16 code is commonly associated with a possible heating, flow or limescale-related problem. The exact meaning can differ between appliance series and model years, so treat this as general guidance and confirm it against your specific model’s documentation before acting.
