Trouble Shooting
Malfunction Cause Remedical Action
Machine operates, but no ice production
Drive motor and Loss of refrigerant
refrigeration unit work
(ventilator runs)
Refrigeration unit stopped * No water in water chamber See water pressure or water level switch
or works at intervals above
(drive motor runs) * Motor cut-out defective Check / replace
* Compressor defective Check / replace
Decreased ice production * Condenser soiled or insufficient Clean with brush or compressed air,
Poor ice quality cooling-water flow never with a wire brush. Water-cooled
machines: bottle brush, antilime agent
* Ambient temperature too high Provide better ventilation,
move maschine away from wall.
* Insufficient amount of refrigerant, Remove leak, evacuate circuit,
bubbles in sight glass replace filter drier, refill with
indicated quantity of refrigerant.
* Lime deposit on auger Clean freezing unit with hot water and
or cylinder antilime agent (Ziegra cleaning agent),
clean mechanically, if required.
* Ice breaker is misadjusted see istallation sheet freezing unit
-ZBE 30-110
* Machine runs in intervals see above (refrigeration unit stopped)
If Ice maker is connected * no sufficient refrigerant check the cooling system of the
to a central refrigeration unit: * Suction pressure too low central refrigeration unit
Machine runs in intervals * pressure fluctuation Data must comply to the ZIEGRA prescription
(If not at hand, ask Ziegra)
Rumbling or loud squeaking
*
Air bubble in pipe between water Remove air bubble
noise chamber and freezing unit
Strong vibrations
Machine freezes up
*
Lime deposit on auger or Clean freezing unit with hot water and
cylinder antilime agent, clean mechanically,
if required.
Occasional gentle squeaking noises
are a typical sign for good and hard ice,
but do not indicate a failure.
Cracking noise in the Cylinder bearing defective Replace
freezing unit
Ice comes out of machine Even small edges or bends can be
in pressed form the cause (see page 2)
("sausages")

Repairs of electrical parts and refrigeration circuit only carried out by a
qualified technician!
Check refrigeration circuit (bubbles
in sight glass). Eliminate leakage,
replace filter drier, evacuate circuit,
refill refrigerant.
After leaving the cylinder the ice is
pressed due to wrong installation of the
ice discharge tube, the extension, or
due to sharp bends.
