Alt. 2 Service switch on the I/O board at the rear of the machine to the right of the electrical connection. Alt.
Troubleshooting Description of fault codes and causes Fault code 01, NO WATER This fault code is generated by the programming CPU card. When filling with water, the level specified by the wash program must be attained within a certain time. This time is normally set to 10 minutes but can vary depending on the type of machine and the software. If the filling time eceeds the maximum allowed filling time, fault code 01 will be displayed.
Troubleshooting 26 Fault code 04, NTC LOW TEMP This fault code is generated by the programming CPU card. This fault code is displayed if the temperature around the NTC sensor is below approx. -9 degrees C. A low temperature means the resistance in the sensor is too high, above approx. 23.7 kohm. This can be because the machine has been standing outdoors, an open circuit in the sensor, a break in the cable to the sensor, etc.
Troubleshooting Fault code 07, DRUM OVERFILLED This fault code is generated by the programming CPU board. The fault code arises if the drum has been filled with water above a predetermined level during an on-going wash program. It can be caused by a blocked level hose, drops of water in the level tube, defective filler valve, defective electronic filler control, etc. Action: • Blow through the level hose and check that it is not blocked and does not contain any water.
Troubleshooting 28 Fault code 09, KLIXON This fault code is generated by the programming CPU board. The fault code means that the temperature in the motor has been so high that the klixon breaker in the motor has been triggered. It can be caused by overloading the motor due to an overloaded drum, low rpm for long periods, defective klixon breaker in motor, short in cable between motor and CPU board, etc.
Troubleshooting 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 breaker, 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.
Troubleshooting 30 Fault code 15, EMERGENCY STOP This fault code is generated by the programming CPU board. The fault code arises if the emergency stop switch has been activated on the machine. The cause can be inadvertent activation of the emergency stop, defective emergency stop switch, incorrect or shorted cable, etc. Fault code 17, DOOR LOCK This fault code is generated by the programming CPU card. The fault code arises if the door lock is locked at the start of the wash program, i.e.
Troubleshooting Fault code 20, I/O MCU INTERLOCK This fault code is generated by the programming CPU board. The program controller has read from the motor control or I/O board that the interlock is not active. The reason for interlock failure can be a problem with the hatch lock, damaged motor supply cables or the I/O board with interlock voltage etc. The most probable fault source is the I/O board. Fault code 21, I/O COMMUNICATION This fault code is generated by the programming CPU board.
Troubleshooting 32 Fault code 23, NO I/O ADDRESSED The fault code means that there is no I/O board addressed in the system at all. Action: • (Requires password) Readdress the existing I/O board from the service menu. Fault code 24, CHECKSUM FROM DLCU This fault code is generated by the programming CPU board. The program unit has detected a fault in the internal communication in the DLCU-processor. Action: • Replace the CPU board.
Troubleshooting Fault code 28, CPU/DLCU LOW LEVELS The DLCU contains a mechanical level monitor which ensures that there is no water in the machine when the lock opens. To ensure that the level monitor functions correctly, the mechanical level monitor is compared with a nominal value generated by the CPU, which is compared with the electronic level check.
Troubleshooting 34 Fault code 32, MOTOR TOO HOT This fault code is generated by the motor control. Each time the motor is started from stationary, the motor control will first measure the resistance between two phases in the motor. The motor control processor governs the output transistors so that a determined DC current flows between two phases in the motor winding.
Troubleshooting Fault code 33, NO INTERLOCK This fault code is generated by the motor control. The motor control must be powered with 230V/50 Hz on the interlock input in order to drive the motor. This signal is confirmation that the door is closed and locked. Motor control receives its commands to rotate the drum from the timer via a serial communication link between the motor control and timer.
Troubleshooting 36 Fault code 35, MOTOR SHORT CIRCUIT This fault code is generated by the motor control. The motor control reads the power consumption of the motor continuously. If the current for some reason gets too high (= exceeds a certain limit), the motor control will cut the current to the motor. After the motor has stopped (= tachometer indicates stationary motor), the motor control will attempt to restart it.
Troubleshooting Fault code 36, INTERLOCK HARDWARE This fault code is generated by the motor control. The motor control must be powered with 230V/50 Hz on the interlock input in order to drive the motor. The interlock circuits in the motor control have been split into two channels so that a component fault in motor control cannot give a false confirmation that the door is locked. These two channels are checked against each other.
Troubleshooting 38 Fault code 38, HIGH DC VOLTAGE This fault code is generated by the motor control unit. The motor control unit constantly measures the voltage over the mains input. If the voltage is too high (= exceeds a certain limit), the motor control unit will shut off the current to the motor. Once the motor has stopped (= the tacho sensor indicates that the motor is stationary), the motor control unit checks to see whether the input voltage is still high.
Troubleshooting Fault code 45, MOTOR NOT FOLLOW This fault code is generated by the motor control. The motor control must always receive information on the rotation of the motor from the tacho sensor in order to rotate. If the tacho sensor is not working, the motor can rotate for max. 10 seconds during the starting process. After this period, the ”MOTOR NOT FOLLOWING” fault code will be activated.
Troubleshooting 40 Fault code 52, CHARGE CIRCUIT DLCU contains an arming circuit that is charged when the door lock coil is to be activated. For safety reasons, this arming circuit must be discharged when the door lock coil is not to be activated. If the arming circuit for operating the door lock is charged when it is not supposed to be, a fault message will be sent to the CPU processor. If the fault ceases, the message will not be sent to the CPU.
Troubleshooting Fault code 54, TACHO, NO SET SIGNAL DLCU counts the tacho pulses from the motor in order to guarantee that the drum is stationary when the door is opened. To ensure that the signal from the tacho generator is working correctly, DLCU compares the tacho signal to a default value from the CPU processor, which is due to the CPU having activated the motor.
Troubleshooting 42 Fault code 56, SET SPEED DOOR OPEN DLCU counts the tacho pulses from the motor in order to guarantee that the drum is stationary when the door is opened. To ensure that the signal from the tacho generator is working correctly, DLCU compares the tacho signal to a default value from the CPU processor, which is due to the CPU having activated the motor. If the default value is on when the door lock is unlocked, a fault message will be sent to CPU.
Troubleshooting Fault code 60, ACTUATOR CIRCUIT The DLCU processor controls the door lock actuator coil. The DLCU processor checks continuously that the coil is engaged. DLCU can detect a break in the circuit (>50 kohm) (DLCU cannot detect a short in the circuit). If there is a break in the actuator circuit, CPU will be notified; the fault message will disappear if the fault ceases.
