14. 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 inlet water flow is low
• The refrigeration system is working in
DEFROST mode
• The discharge pipe is partially obstructed
• Fan motor is not running
• Refrigerant is leaking
• Check the water flow and solve if
not enough
• Return to FREEZE mode
• Clean the discharge pipe and
solve the obstruction
• 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
