There are several possible reasons for this :
A. If the coffee comes out normally, but the cycle does not stop, do not reprogram the machine. Contact a technician.
B. If the coffee does not flow, or flows slowly, check the flow in the delivery brewhead when it is empty (without locking the filter holder in position): you should see a conical stream of clear water.
1- If this is the case, the causes of the fault could be as follows :
    - The ground coffee used is too fine: check the grinder settings.
    - The sieve or the filter holder spout is blocked: Soak the whole filter holder unit in hot water,       adding RENEKA soap tablets.
2- If this is not the case, contact the technical service.
Probable causes: blocked showers, diffuser or nozzle .
