5 TROUBLESHOOTING
Note:
All KFE machines have a timer that delays start-up. This delay is necessary for guaranteeing the reliability of the compressor.
OBLIGATIONS:
FORBIDDEN:
NEVER attempt to start the machine by forcing the main contactor. Forcing the start-up may result in irreparable damage to the machine.
NEVER attempt to open valves or unions. The system may contain high pressure.
NEVER touch pipes or other parts of the system. The system may contain high pressure.
FAILURE
The machine does not start
The machine is running BUT does not produce ice.

A - Check the power supply is available. The machine panel features some lights, depending on the model. At least one of these lights MUST be lit or
B - For THREE-PHASE versions only: Check the connection phase (direction of rotation). Invert two phases if necessary.
E - Check the status of the ice level sensor (OPTIONAL), if installed. This sensor has two adjustment knobs. Follow the calibration instructions.
*F -Check the ice outlet. A sensor detects any ice build-up on the ice-breaker blade.
*G -Magnetothermal circuit breaker triggered inside machine due to possible short-circuit or overload.
*H -FAULTY electric or electronic component.
*I - Check the system's MAXIMUM pressure. A pressure switch detects the maximum pressure. NOTE: REARMING may be MANUAL or AUTOMATIC,
depending on the model.
*L - Check the system's MINIMUM pressure. A pressure switch detects the minimum pressure. (see cause M).
*M - Check for GAS missing. Retrace the leak, empty the system and reload the GAS.
*N - Incorrect GAS load. Empty the system and reload.
NOTE: In versions with electronic system with LCD display, many messages indicating the cause of the fault are displayed.
The LCD display may be positioned either INSIDE the electric panel or on the REMOTE control panel.
If none of the checks failed, contact a Service Centre or the manufacturer.
A - Check the LIQUID INDICATOR near the compressor. NO GAS bubbles must be visible.
*B - Check the system's MINIMUM pressure. A pressure switch detects the minimum pressure. (see cause M).
*C - Check for GAS missing. Retrace the leak and reload the GAS.
*D - Incorrect GAS load. Empty the system and reload.
*E - Check for any MECHANICAL defects on the ice-breaker blade.
*F - Check for any MECHANICAL defects on the support bearings of the ice-breaker blade.
NOTE: In versions with electronic system with LCD display, many messages indicating the cause of the fault are displayed.
The LCD display may be positioned either INSIDE the electric panel or on the REMOTE control panel.
If none of the checks failed, contact a Service Centre or the manufacturer.
