FISHER & PAYKEL _ DEIX1 AA WW _ INTUITIVE DRYER _ FAULT CODES _ 2 of 2





                                          { 2 of 2 }
Contn:

 FAULT CODE 16:  AIRFLOW RESTRICTION [USER WARNING]

Airflow restriction.
Remedy:
  • Check that the lint bucket is empty and the filter is clear.
  • Ensure that the exhaust duct is not restricted, blocked or kinked, preventing good airflow.
  • Ensure that there is nothing inhibiting unrestricted airflow through the heater housing, through the drum, lint filter, lint collector and through the exhaust duct, and that the element has not shorted. If the dryer is located in a closet ensure there is adequate ventilation for air intake.
  • Check that the voltage is not too high.
  • Check for element shorts or low resistance.
  • Replace the automatic thermostat. 
  • Replace the motor control module.
                                                                   Element Assembly

  • Two sets of Nichrome wire elements linked in parallel between Mica plates. A ceramic insulator is used to support the element assembly in the housing.

Cold Resistance 13.5 Ohms
Current 15 Amps
Power 3.6 kW
Voltage 240 Volts

Cold Resistance 37 Ohms
Current 5.8 Amps
Power 1.4 kW
Voltage 240 Volts

                                                    THERMOSTAT CUTOUT


  • Type SPST
  • Trip Temperature 70°C ± 3o
  • Reset Temperature 55°C ± 4o
FAULT CODE 20:  DOOR ACTUATOR STALLED.

FAULT CODE 21:  DOOR ACTUATOR REQUIRED EXCESS VOLTAGE
Remedy:
  • Ensure there is no weight placed on the lid of the product (e.g. clothes basket). If so, remove the weight and retest.
  • Inspect the installation, making sure that the cabinet sits evenly on the floor. If excess load is placed on the cabinet, it can cause the sub-deck assembly to twist.
  • Inspect the front inside edge of the top deck for any signs of excessive inwards bowing as this can cause it to catch on the door grabber, resulting in excess current draw on activation. The bowing can be caused by a bowed top deck or by incorrect assembly of the top deck to the cabinet front.
  • Ensure the user intervention tab is not inhibiting door grabber movement.
  • Check that the actuator linkage is located correctly. There must be no gap between the linkage and the plastic moulding. 
  • Check that the actuator housing is in place, and that the four retaining lugs are correctly located. Early models may have aluminium tape holding the housing in place. If so, ensure that the tape is replaced when the housing is refitted.
  • Remove the actuator housing and look for obvious signs of things that are out of position (can the worm drive be rotated freely both backwards and forwards by hand, is the actuator motor in place?)
  • Replace the faulty door actuator mechanism.
  • Replace the door grabber, linkage and housings.
  • Replace the sensor module.
FAULT CODE 22:  DOOR ACTUATOR OPEN CIRCUIT.
 Remedy:
  • Check that the actuator wiring is plugged into the sensor module and is not open circuit. If faulty, replace.
  • Replace the sensor module.
                                                              Sensor Module


FAULT CODE 23:  DOOR ACTUATOR MOVEMENT INTERRUPTED BY LOW VOLTAGE
The door actuator movement was interrupted by low voltage (brown out).
Remedy:
  • Ensure mains voltage is within +10% and –15% of nominal.
  • Replace the sensor module, as voltage measurement circuit may be reading incorrectly. 
  • Replace the motor control module, as it may not be supplying sufficient power to the sensor module. When display is off, approximately 24V DC is supplied.
                                                          Motor control Module


FAULT CODE 24:  DOOR ACTUATOR MOVEMENT TOOK TOO LONG
  • Remedy: As per fault code 21.
FAULT CODE 28:  DATA RETRIEVAL ERROR FOLLOWING LOSS OF POWER.
Remedy:

  • Switch off the mains power supply to the dryer for at least 10 seconds and confirm error.
  • Replace the motor control module.
FAULT CODE 29:  BROWN-OUT DATA RETRIEVAL ERROR
Remedy:
  • If the fault occurs every time the dryer is turned on, replace the sensor module.
  • Replace the motor control module
FAULT CODE 30:  Lid Lock unable to Lock – (User Warning).

Reason: The lid lock failed to lock. (Not user displayed.)
Remedy:
  • Ensure the lid is closed and the tongue engaged.
  • Replace the lid lock harness.
  • Replace the lid lock.
  • Replace the sensor module.
FAULT CODE 45:  Display Module ROM Check Error.

On power up, the display has checked its memory against a known reference and found differences.
Remedy:
  • Replace display module.
                                                            Display Module


FAULT CODE 105:  Comms Error Time Out

Communications failure between the sensor module and display module.
Remedy:
  • Visually check the contacts on the RAST (edge) connector at each end on the harness between the sensor module and display module.
  • Using a multimeter check for continuity of the wires on this harness.
  • Replace display module.
  • Replace sensor module.
Note: The green Air Dry LED illuminated without the fault “beeps” indicates the dryer is in a low mains voltage (brown out) state, and may be momentarily displayed when the supply power is turned off.
