Fault code 11, UNB. ON AT PROG. START
This fault code is generated by the programming CPU board. The fault
code means that the mechanical imbalance breaker is already active when
the wash program starts. It can be caused by a defective imbalance brea-
ker, mechanical problem making the imbalance breaker always active,
short in the edge connection or cables, etc.
Fault code 12, PROGRAM FAILURE
This fault code is generated by the programming CPU board. This fault
code means that one of the CPU board memories can be defective.
Action:
• Try reloading the software into the machine memory. If this does not
help, the CPU board will have to be replaced.
Fault code 13, NO MOTOR COMM.
This fault code is generated by the programming CPU board. The fault
code arises if the CPU board cannot communicate with motor control via
the communication cable.
Actions:
• Check that there is power reaching the motor control.
• Then check that the indicator LED on the motor control is on. The LED
can be seen by looking down by the motor control edge connections.
• Check also that the communication cable between the CPU board and
the motor control is intact and not damaged. Measure also with a refe-
rence instrument to see whether there is contact between all the leads
in the communication cable.
Fault code 14, LEVEL ADJUST
This fault code is generated by the programming CPU board. The fault
code arises if the circuit board's internal level system has not been calibra-
ted by the manufacturer.
