8. TROUBLESHOOTING INSTRUCTIONS
The machine does not
start
(seletctor ON with green
LED).
Master switch open. Close the switch.
Lid raised or not assembled.
Lower the lid and/or check that it is
assembled correctly.
Incorrect power supply. Check power supply.
Electrical anomaly. Contact the technician.
The compressor
functions intermittently
from the first batch
freezing phases.
Air-cooled machines: air condenser
dirty or fan faulty.
Clean the condenser with a brush and
make sure the fan works properly.
Water-cooled machines: no
condensation water.
Make sure there is water in the water
system to which the machine is connected.
Check the cocks.
The batch freezing times
lengthen and/or the ice-
cream appears wet.
Slight condensation. Check the installation conditions Chap.4.5.
High room temperature.
Check that the room temperature does not
exceed 32°C.
High liquid mixture temperature.
Maximum machine production is obtained
with a liquid mixture at 4°C. Using mixtures
at higher temperatures means that batch
freezing times are lengthened: this is
normal and does not constitute an anomaly.
Worn scrapers. Check wear and replace them if necessary.
Refrigeration system anomaly. Contact the technician.
Unbalanced mixture or incorrect
amount introduced.
Check that the amount of mixture
introduced is correct and that it is balanced
properly.
The product is too soft.
Insufficient batch freezing time or
preservation texture regulator
positioned incorrectly.
Select a longer time on the timer and/or
higher numbers on the regulator.
The product is too hard.
Excessive batch freezing time or
preservation texture regulator
positioned incorrectly.
Select a shorter time on the timer and/or
lower numbers on the regulator.
The machine becomes
noisy during batch
freezing.
Presence of ice on the cylinder wall.
The ice-cream is ready to be extracted.
Check that the quantity introduced into the
cylinder is not lower than the minimum
allowed.
