Max. filling time is defined in Config. 1 parameter MAX FILL TIME. This error message can be turned off in Configuration - Error code. Possible causes: Long filling times can be caused by a leaking drain valve, blocked filler valve, defective filler valve, defective valve control board, clogged level sensor hose, leaking level system, etc.
  • Page 72 Service Manual 11:5 WATER HIGH TEMP This error code is shown if the temperature sensor indicates temperature above + 98°C/208°F. Maximum allowed temperature is defined in Config. 2 parameter MAX PROG TEMP. Possible causes: This high temperature means that the resistance in the sensor is too low (< 350Ω on all machines except Barrier Washers) or too high (>137Ω...
  • Page 73 Service Manual 11:9 DRUM OVERFILLED This error code is shown if the mechanical level sensor connected to input DRUM OVERFILLED detects a high level (used primary in W&D machines) Possible causes: This error code can be caused by for example water inlets not closing correctly, faulty level switch, blocked level hose, drops of water in the level hose, foam in drum or level hose, etc.
  • Page 74 Service Manual 11:27 LEVEL OFFSET This error code is shown at program start if the level sensor indicates a level above what the control system CPU can compensate for.

  • Page 76: Main Dryer

    Service Manual MAIN DRYER 12:1 O.H. THERMOSTAT - INLET AIR This error code is shown if the input O.H. INLET AIR is deactivated. Normally this is due to that protection thermostat for inlet air has trigged due to overheating. The overheating thermostat for inlet air needs to be mechanically restored. Cut power and turn off gas supply (if gas heated) and check contactors/heat relays before restoring the thermostat.
  • Page 77 Service Manual 12:4 INLET AIR SENSOR - SHORT-CIRCUITED The error code is shown if the analog input INLET AIR TEMP (PT100) is reading a resistance of less than 100 Ω. Probably caused by broken PT100 sensor or damaged wiring. If the inlet air temperature in the SHOW INPUTS menu show a temperature of 0 °C the inlet air sensor is shorted. When the inlet air sensor is restored the error code is automatically reset and the ongoing program will continue.
  • Page 78 Service Manual 12:6 OUTLET AIR SENSOR - SHORT-CIRCUITED The error code is shown if the analog input OULET AIR TEMP (NTC) is reading a resistance of less than 330 Ω. Probably caused by broken NTC sensor or damaged wiring. If the outlet air temperature in the SHOW INPUTS menu shows a temperature of 100 °C the outlet air sensor is shorted.
  • Page 79 Service Manual 12:10 HP HIGH PRESSURE CHECK COOLING SYSTEM AND FILTERS The error is activated if the input HP HIGH PRESSURE (high pressure switch, P1) has tripped. The errror can be trigged if there is no cooling water to machine or if the airflow is obstructed, by lint, overload, etc. The error can be restored with the knob when the pressure is restored and the ongoing program will continue.
  • Page 80 Service Manual 12:14 GAS ERROR PRESS GAS RESET BUTTON The error code is shown if input GAS ERROR is activated. This means that no flame has been detected by the gas control box. The metal probe of the flame sensor generates an electrical current when exposed to the burner's flame. This signal is detected by the ignition control module which, in turn, cuts off the gas valve immediately if the sensor does not indi- cate flame within 3 attempts at each 10 seconds.
  • Page 81 Service Manual 12:18 REDISTRIBUTION OF LOAD NEEDED The error code is shown if the input VACUUM has deactive several times during program run and the function to han- dle vacuum error during program run has failed to recreate vacuum in the machine.

  • Page 84 Service Manual 13:11 UNLOADING DOOR NOT LOCKED This error code will be shown if the control system has not detected the input UNLOADING DOOR LOCKED to be ac- tive within a certain time after closing the unloading door. Possible causes: This can be caused by a mechanical problem preventing door lock to lock, defective door lock, loose cable connec- tion to door lock, broken cables to door lock or mechanical problem with emergency opening of the door.
  • Page 85: Main W&D

    Service Manual 13:16 DRUM LOCK POSITION SWITCH The error code is shown if inputs DRUM UNLOCKED and DRUM LOCKED are both active or inactive at the same time during positioning sequence. By pressing the start button it is possible to have another trial. Possible causes: Heavy unbalance in drum that prevents the motor to position the drum.
  • Page 86: Main Dryer

    Service Manual MAIN DRYER 15:2 UNLOADING DOOR OPEN Only on Pocket washer: This error code will be shown if the control system detects that the input DOOR CLOSED 2 (unloading side) has been deactivated during an on-going program. The error can only occur during an on-going program. Possible causes: This can be caused by for example a bad or defective door lock, loose cable to door lock, problem with door lock edge connection, defective input on I/O unit type 10 etc.

    Service Manual DRUM MOTOR OBIWAN 23:1 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.
  • Page 102 Service Manual 23:3 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.
  • Page 103 Service Manual 23:6 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 cir- cuits in the MCU have been split into two channels so that a component error in MCU cannot give a false confirma- tion that the door is locked.

  • Page 106 Service Manual 40:22 I/O BOARD MISHMASH The error code is shown if wrong Type of I/O unit is fitted. Could also occur if adressessing of the I/O units is made in a incorrect way. After addressing of I/O units the CPU reads the Type of each unit. If there is a mismatch between what the Type of I/O unit the CPU finds, and what the I/O unit type the software con- figuration expects, the error will be shown.

    Service Manual INTERNAL COM. I/O TYPE 10 41:1 CHARGE CIRCUIT The DLCU on I/O board type 10 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, an error message will be sent to the CPU.
