Dosage problems
105-second safety system of the coffee unit
Thanks to such a safety system, the maximum infusion time is reduced and ranges to 1 minute and
45 seconds. As a result, the infusion process automatically stops, if the dosing device no longer
works or if the flow capacity is insufficient so that the motor-pump and the valve of the unit are
better protected.
When the safety system is on,
t is displayed.
The flow of the water going through the coffee filter is insufficient.
The infusion time corresponding to the programed dose is more than 105 seconds.
The pump is faulty
Check:
- The pressure
- Power supply:
* cables
* condenser
- The mechanical state of
the motor-pump:
* filter
* coupling
One of the water passage
holes is clogged.
Check the hydraulic circuit:
- Nozzle of dosing device
- Unit nozzle
- Unit filter
- Unit valve
- Coffee filters
- The spout
The coffee grind is too fine:
- Use a coarser grind.
