HEATSINK
TOO HOT

This error code is generated by the MCU for drum motor.
There is a temperature sensor (NTC) mounted on the MCU cooling flange next to the power transistors in the output stage. If the temperature of the cooling flange gets too high (> 90°C) the error code will be set to protect the transistors.
The cause of high cooling flange temperature can be e.g. a stiff drum in combination with intensive use and high ambient temperature. There may also be an error in the motor (sticking bearings or short circuit in windings, which impairs the efficiency of the motor).
Recommended actions:
1) Make sure the drum turns easily.
2) Check the value on the error code counter for the error code.
3) Check the last 8 MCU error codes.
4) Start a 90°C normal program with load on continuous operation and measure the temperature of the motor and MCU.
5) Replace the defective part.

21:2

MOTOR
TOO HOT

This error code is generated by the MCU for the drum motor.
Each time the motor is started from stationary, the MCU will first measure the resistance between two phases in the motor. The MCU processor governs the output transistors so that a DC current flows between two phases in the motor winding. The actuation of the transistors is a measure of the voltage applied to the winding and the resistance can be calculated using the current and voltage values. The resistance can then be converted to a temperature since the winding resistance at 20°C and the temperature coefficient are known. If the average value of the four latest temperature readings is higher than the maximum motor temperature (e.g. 150°C), the error code will be shown.
Possible causes:
The cause of high motor temperature can be a stiff drum, possibly in combination with intensive use and high ambient temperature. There may also be an error in the motor (sticking bearings or short circuit in windings, which impairs the efficiency of the motor). There could also be a contact error in the connectors between the MCU and the motor or an error in the motor cable. An error in MCU temperature measurement circuits can also occur.
Recommended actions:
• Make sure the drum turns easily.
• Check the value on the error code counter for the error code.
• Check the last 8 MCU error codes.
• Measure the three phases to the phase resistors on the MCU motor connector (disconnect MCU and take the reading in the cable connector) to make sure they are the same.
• Start a 90°C normal program with load on continuous operation and measure the temperature of the motor and MCU.
• Replace the defective part.

21:3

NO
INTERLOCK

This error code is generated by the MCU for drum motor.
The MCU must be powered with 230V / 50 or 60 Hz on the interlock input in order to drive the motor. This signal is a confirmation that the door is closed and locked.
MCU receives its commands to rotate the drum from the CPU via a serial communication link between the MCU and CPU. Since the CPU also has access to the interlock signal, the CPU must never send a run command to the MCU if the interlock signal is missing. If this does happen, this error code will be shown.
Possible causes:
The cause of this error code being activated can be e.g. a break in the cable leading the interlock signal to the MCU. There may also be an error in the connector in the door lock, which connects 230V / 50Hz to the interlock signal. An error in the interlock circuits of the MCU can also set this error code.
Recommended actions:
1) Use a multi-meter to check that the interlock signal is present on X302:1-2 when the door lock is activated. Read also bit 1 in the second byte under MCU STATUS in the service program (the bits are numbered from 0 to 7 where bit 0 is on the far right). If bit 1 in the second byte is 1 then the lock is open, while a 0 indicates that the lock is closed.
2) Replace the defective part.

21:4

NO COMMUNIC-
ATION

This error code is generated by the MCU for drum motor.
MCU detects there is a problem in communication with CPU.
Possible causes:
• Bad contact in harness or connectors between CPU and MCU
Recommended actions:
1) Check wiring, connections between CPU and MCU.

21:5

MOTOR SHORT CIRCUIT

This error code is generated by the MCU for drum motor.
The MCU reads the power consumption of the motor continuously. If the current for some reason exceeds a predetermined limit, the MCU will cut the current to the motor. After the motor has stopped (= tachometer indicates stationary motor), the MCU will attempt to restart it. If the MCU then detects high motor current again, this error code will be activated. If on restarting after a first short circuit, the MCU rotates normally, the error code will not be shown.
Possible causes:
This error code can be activated for a number of reasons:
• Short circuit in motor. Measure motor windings with a Motor Tester.
• Short circuit internally in motor winding (impaired efficiency, higher current consumption).
• Short circuit in motor cables.
• Short circuit in connectors.
• Drops of water causing short circuits in the motor connector.
• Short circuit in the MCU output transistors.
• Bad contact in tacho signal.
• Bad contact in interlock signal.
Recommended actions:
1) If the error is a stable one, it is generally not difficult to locate the defective unit through resistance measurement and testing with the service program. Measure motor windings with a Motor Tester.
2) Further information can be obtained by studying the contents of MCU ERROR LOG 1 and MCU ERROR LOG 2.
Review following:
SHORT CIRCUIT 2 (specifies how many times the error code has been active).
SHORT CIRCUIT 1 (specifies how many times the current limit has been exceeded. The difference between short circuit 1 and short circuit 2 indicates how many times there has been a short circuit 1 that has not been confirmed when restarting the motor).
LAST FAULT CODE N/8 (shows the 8 latest error codes).
TACHO ERR. LOW SPEED (can give a clue in case of intermittent errors).
TACHO ERR. HIGH SPEED (can give a clue in case of intermittent errors).

21:6

INTERLOCK HARDWARE

This error code is generated by the MCU for drum motor.
The MCU must be powered with 230V / 50 or 60 Hz on the interlock input in order to drive the motor. The interlock circuits in the MCU have been split into two channels so that a component error in MCU cannot give a false confirmation that the door is locked. These two channels are checked against each other. If this check gives an incorrect result this error code will be shown.
Possible cause:
The reason for this error code being activated can be attributed to an error in the interlock circuits in motor control.
Recommended action:
• Replace MCU.

21:7

LOW DC
VOLTAGE

This error code is generated by the MCU for drum motor.
The MCU constantly measures the voltage over the mains input. If the voltage is below a predefined limit, the MCU will shut off the current to the motor. Once the motor has stopped (= the tacho sensor indicates that the motor is stationary), the MCU checks to see whether the input voltage is still low. If it is, this error code is shown.
The reason for this error code being activated can be low mains voltage or that the machine’s on/off
switch has been operated in an unsuitable manner.
Further information can be obtained by studying the contents of MCU ERROR LOG 1 and MCU ERROR LOG 2:
• UNDERVOLTAGE 2 (specifies how many times this error code has been active).
• UNDERVOLTAGE 1 (specifies how many times the voltage has dropped below the limit. The
difference between undervoltage 1 and undervoltage 2 indicates how many times there has been an undervoltage 1 without it being confirmed when the motor has stopped).
• LAST FAULT CODE N/8 (shows the 8 latest error codes) Undervoltages can be registered even during normal operation. Consequently, a small number of registrations need not mean that there is an error in the MCU.
Action
• Check that the supply voltage is stable and never drops below nominal voltage - 10%.
• Check the fuses and cables.
• Check the supply voltage in the network cabling and at the MCU in the machine.

21:8

HIGH DC
VOLTAGE

This error code is generated by the MCU for drum motor.
The MCU constantly measures the voltage over the mains input. If the voltage exceeds a predefined limit, the MCU will shut off the current to the motor. Once the motor has stopped (= the tacho sensor indicates that the motor is stationary), the MCU checks to see whether the input voltage is still high. If it is, this error code is shown.
Recommended action:
1) Check incoming AC voltage.

21:12

NO PARAMET.
SET IN MC

This error code is generated by the MCU for drum motor.
The MCU contains several different parameter sets for different motors. During power up the control system checks that the correct parameter set digit is written into the MCU. If not, the control system will write down the parameter set digit defined in fixed configuration.
If the MCU discovers that no parameter set value is written down into the MCU, the error code will be shown.
Possible causes:
This can be caused by wrong software in CPU or wrong MCU for the current machine.
Recommended actions:
Make sure correct machine software and correct MCU are used.

21:13

UNBALANCE

This error code is generated by the MCU for drum motor.
The MCU monitors the unbalance switch status. If the status is active already at program start, this error code is shown.

21:15

MOTOR NOT FOLLOW

This error code is generated by the MCU for drum motor. The MCU 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, this error code will be activated.
Cause
• Break in the cables between the tacho sensor and the MCU.
• Break in connectors in tacho cables.
• Break in one of the phases to the motor (cables or connectors). This error can be suspected if the motor does not rotate for 10 seconds (the motor will not start with only two phases).
• Error in tacho generator.
• Error in tacho circuits in the MCU.
Further information can be obtained by studying the contents of MCU ERROR LOG 1 and MCU ERROR LOG 2. Study the following:
• MOTOR NOT FOLLOW (specifies how many times this error code has occurred).
• LAST ERROR CODE N/8 (shows the 8 latest error codes).
• TACHO ERR. LOW SPEED (can give a clue in case of intermittent errors).
• TACHO ERR. HIGH SPEED (can give a clue in case of intermittent errors).
Action
• Replace the defective part.
