The water tubes present constrictions. Avoid constrictions.
The water condensing faucet/s are partially or totally closed.
The static pressure valve must be newly regulated, otherwise it is broken. Call the Assistance
Service.
Note:
To check if the water correctly flows and if the static pressure valve is regulated, it is sufficient
to temporarily detach the water outlet tube (at the end not connected at the device). Water
must flow only when the refrigerating system is in function.
The incoming water’s temperature is higher than that prescribed in the Technical Handbook.
Cause:
The compressor is overheated due to a lack of ventilation. Clean the loopholes and restore the
minimal distances for the circulation of air at the sides of the device.
Note:
it may be necessary to wait up to 30 minutes for the thermal protections to cool down.
Break down the refrigerating system, or the electric controls. Call the Assistance Service.
Unusual noises.
The noisiness comes, mainly, from the cylinder, when the beating is activated.
Cause:
Beater's blades are not correctly adjusted. Proceed as describes in Par. 7. 5 - Adjusting blades.
A layer of ice has developed between the beater and the cylinder: the mixture is not idoneous, or is not
sufficient.
Beater's blades may be damaged or worn. Check that the plastic blades' scraping edges do not show
any dents, scratches or wear marks which cannot be mended by adjusting. Should this be the case,
replace blades.
The beater and/or the cylinder are damaged or excessively worn. Call the Assistance Service.
Cause:
The beater and/or the cylinder have gone through a sudden temperature's changing, and stress me-
chanically. Stop the machine and wait for a few minutes.
The noisiness DOES NOT come from the cylinder, or it there is also when the beating is not activated.
Cause:
Inside break down. Call the Assistance Service.
