Fault Code 20 Door Actuator Stalled.
Remedy: As per fault code 21.
Fault Code 21 Door Actuator Required Excess Voltage.
Remedy: (1) Ensure there is no weight placed on the lid of the product (e.g. clothes
basket). If so, remove the weight and retest.
(2) 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.
(3) 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.
(4) Ensure the user intervention tab is not inhibiting door grabber movement.
(5) Check that the actuator linkage is located correctly. There must be no gap
between the linkage and the plastic moulding.
(6) 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.
(7) 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?)
(8) Replace the faulty door actuator mechanism.
(9) Replace the door grabber, linkage and housings.
(10) Replace the sensor module.
Fault Code 22 Door Actuator Open Circuit.
Remedy: (1) Check that the actuator wiring is plugged into the sensor module and is not
open circuit. If faulty, replace.
(2) Replace the sensor module.
Fault Code 23 Door Actuator Movement Interrupted By Low Voltage.
The door actuator movement was interrupted by low voltage (brown out).
Remedy: (1) Ensure mains voltage is 10% and –15% of nominal.
(2) Replace the sensor module, as voltage measurement circuit may be reading
incorrectly.
(3) Replace the motor control module, as it may not be supplying sufficient
power to the sensor module. When the display is off, approximately 24V DC
is supplied.
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: (1) Switch off the mains power supply to the dryer for at least 10 seconds and
confirm the error.
(2) Replace the motor control module.
Fault Code 29 Brown-Out Data Retrieval Error.
Remedy: (1) If the fault occurs every time the dryer is turned on, replace the sensor
module.
(2) Replace the motor control module.
