Problems that may occur while the machine is functioning
Frozen cylinder phenomena
INFO: The frozen cylinder occurs when there is ice formation in the cooling cylinder; this results in that the resistance on the beater and the motor become too larger for the soft ice cream machine to handle and may cause serious damage to the soft ice cream and frozen yogurt machine. This phenomenon is usually noticed by abnormal friction noise from the cooling cylinder and a sudden increase of the value on the display for the motors current (>6.00).
HOW to avoid it:
- Always follow the mixing rate specified between the soft ice cream powder and the amount of water (ex. 1 to 3 for soft ice cream powder);
- Always remember to remove all the water from the cooling cylinder after cleaning.
- Keep balance of the amount of soft ice cream mixture in the two hoppers.
- Turn off the ice cream and frozen yogurt machine if it is not used for more then 30 min and let it “rest” for 5 minutes or extrude some soft ice cream.
- Always keep ice cream mixture in the hopers when the ice cream machine is on.
WHAT to do if it happens:
- Turn off the soft serve freezer for 20 min, so the ice formation can melt by pressing the STOP button.
- Remove the air-tube and replace it up side down.
- Press the CLEAN button too control the resistance in the cooling cylinder.
- If the value is bellow 5.50 on the display for the motors current, drain the cooling cylinder from water and then remove the air tube, to let new ice cream mix fill the cylinder.
- Push the clean button to fill the cooling cylinder and return the air tube with the little hole in downward position.
- Finally press the Auto button, to start production of soft ice cream again.
Operation conditions that will result in “AUTO”-protection.
The “AUTO” protection will be activated if any of the operation conditions mentioned bellow would occur. The soft ice cream machine will then be in stand-by condition for 10 minutes and then return into normal operating condition.
- Because of the “Frozen cylinder” phenomena.
- The voltage is below 198 V, low-voltage protection.
- The voltage is above 238 V, high-voltage protection.
- The compressors temperature is high, then PTC protective device will stop the compressor, to let it cool down for 10 minutes.
NOTE: the soft serve freezer can be returned into normal operating condition manually by pressing the Stop button. Before you restart the ice cream and frozen yogurt machine, please ensure that the
problem been solved.
NOTE: If the soft serve freezer often enters the protective mode, it is recommended that a manostat (5KVA) is purchased and used to stabilize the voltage.
The soft serve freezer doesn't start
- The auto-protection of the soft ice cream machine is triggered.
- The soft serve freezer is not connected to the main power source.
- Ensure that the power supply is normal and the voltage is within the permitted range.
- Control that the power plug is well.
The ice cream machine do not stop automatic during AUTO condition.
- Because of to little ice cream mixture in the cooling cylinder.
- That the surrounding temperature is to high (>38 ºC).
- Control that the little hole in the air tube is in downward position.
- Try to lower the surrounding temperature.
NOTE: These two conditions may results in that the necessary resistance in the cooling cylinder cannot be reached and the ice cream and frozen yogurt machine will not stop.
The soft serve freezer will not stop when pushing STOP button.
- The springy touch pole or its spring has been deformed or damaged.
- Repair or change the pole or its spring.
The ice cream is too hard or too soft
- The icecream hardness value is not properly set.
- The ice cream mix has not been properly prepared.
- The ice cream mix that is used is not suitable for this ice cream and frozen yogurt machine.
- The ice cream is distributed before the refrigeration cycle is finished.
- The amount of soft ice cream in the cooling cylinder is to little.
- Adjust the hardness value.
- Follow the instruction provided together with ice cream mixture.
- Consult with your local distributor or contact us if none is available.
- Never start distribution ice cream before the cooling cycle is finished and the compressor and motor stops and the motors current drops down quickly to zero.
- Control that the air tube is installed correctly and that there is enough of mix in respective hopper.
NOTE: When soft serve freezer is operated manually, then the motors current should never be bellow 4.00 during distribution, otherwise the product will be to soft to be served.
Ice cream comes out behind the discharge door
- The O-ring behind the discharge door is placed incorrectly.
- The O-ring behind the discharge door is deformed.
- Replace the O-ring correctly and make sure that the bolts holding the discharge door is closed and secure.
- Change the O-ring to a new one.
Big amount of ice cream in the drip pan
- The ripple seal ring is installed incorrectly.
- The ripple-sealed ring is damaged.
- Reinstall the ripple-sealed ring.
- Change the ripple-sealed ring into a new one.
Mixture or ice cream leaks from the draw valves
- The O-rings is installed incorrectly.
- The O-rings are damaged.
- Reinstall the O-rings.
- Change the O-ring into a new one.
The Ice cream mixture do not flow into the cooling cylinder
- The temperature of the mix is too low.
- To little water was used when preparing the mix.
- Old mix is used that has a different viscosity (usually to thick).
- Do not let the mix become colder than 1-4ºC.
- Follow the mixing rate according to the manufacturer.
- Try to always use fresh mix.
