15. TROUBLESHOOTING GUIDE
NOTE: the following procedures must be performed by a qualified service technician.
Problem Possible cause Solution
The machine does not cool,
or cools only partially and
the compressor is running
 The space around the machine is
inadequate for ventilation
 The refrigeration system is working in
DEFROST mode
 The condenser filter is clogged with
airborne particles
 Fan motor is not running
 Refrigerant is leaking
 Allow at least 20cm between the
machine and anything next to it;
keep it away from heat sources
 Return to FREEZE mode
 Clean the filter
 Check the fan motor’s electrical
connections and, if disconnected,
reconnect. If still not operating,
replace the motor
 Locate the leak, eliminate it and
recharge the system
The machine does not cool,
or cools only partially and
the compressor is not
running
 Electrical components of the compressor
are not functioning
 Some electrical connections are not
complete
 The compressor is malfunctioning
 No current is coming to the electronic
board
 Replace the malfunctioning
components
 Check the contacts and correct
those incomplete
 Replace the compressor
 Check the electrical connections
to the pc board as well as the
transformer feeding the PC
board and correct
The machine over-freeze,
making the auger movement
slow or stopped
 The product brix is too low
 The screw setting for the consistency
control system is set too far toward the
“+” position
 The limit micro-switch arm is bent away
from the gear motor and prevents
contact
 The level of the product in the bowl is
too low
 The compressor PC board contact don’t
open
 Check the product brix and
correct
 Reset the screw toward the “-“
position to produce a thinner
consistency product
 Using pliers, straighten the limit
switch arm
 Add more product or turn the
refrigeration “Off”
 Replace the PC board
The machine is noisy  The fan motor blades are hitting internal
components
 Check and correct
The main power switch is
“ON” but the unit s not
running
 The fuses are blown
 Some electrical connections are not
complete
 The control board is faulty
 The gear motor is malfunctioning
 Replace the fuses
 Check the contacts and correct
those incomplete
 Replace the control board
 Replace the gear motor
The bowl is leaking  One of the bowl seal is not in place  Replace or reposition the seal
The dispensing valve is
leaking
 The dispensing valve has been
incompletely or incorrectly replaced in its
position
 The free movement of the valve is
impeded
 Dispensing valve o-rings are damaged
 Reassemble and replace
 Clean and lubricate the valve
and the valve cylinder with the
lubricant provided with the
machine
 Replace the o-rings
Product is flowing into drip
tray through drainage pipe
 The bell shaped seal between the front of
the cylinder and the auger hub has not
been reinstalled properly
 The bell shaped shaft seal or the spindle
bushing seal is damaged or worn
 Find the seal and put it back in
place
 Replace the damaged/worn seal
and check the condition of the
drive shaft
The auger is not turning  Some electrical connections are not
complete
 The control board is faulty
 The gear motor is malfunctioning
 Check the contacts and correct
those incomplete
 Replace the control board
 Replace the gear motor
The auger is creating noise
as it rotates
 The bell shaped shaft seal has been
replaced without lubrication or is
damaged
 The auger has been incompletely or
incorrectly reassembled
 Replace or clean and lubricate
with the lubricant provided with
the machine
 Check and correct
“FILTER” or “CUT/OUT”  The filter is dirty and needs to be  Clean and replace filter following
