4.1 Disassembly warnings
The mains cable must be disconnected from the power supply when disassembling or repairing the
machine.
The loom harness and terminals used must be for the correct wire size and the correct tools must be
used to crimp any terminals onto the harness. Insulation tape must be used where appropriate.
When attaching terminals to the mating connectors, always ensure that they are pushed fully on.
When attaching a wire via a screw terminal, ensure that sufficient wire is underneath the screw
terminal. Ensure that the screw is tightened satisfactorily.
The loom harness should not touch any moving parts or sharp edges. The wiring route around high
temperature objects (e.g. motor) should be followed as per the initial construction.
Always use the specified screws

4.2 Disassembly methods
1. Control panel assembly disassembly
1. Unfasten the two screws at the rear of the
top cover and slide top cover backwards
2. Remove the bottle
3. Remove 4 screws at the front of the dryer
from the control panel and cross brace
4. Remove 2 screws inside the slots on the
control panel
5. Remove all of the connections from the
back of the PCB

6. Remove the screws holding the PCB to the
control panel. The PCB’s can be removed by
unscrewing and unclipping where necessary.
2. Disassembling the RFI filter and water level sensor
Disassembling the RFI filter:
Remove the loom terminals from the filter. Unfasten
the two screws from the filter in order to remove the
filter from the upper bracket.
Disassembling the water level sensor:
Remove the top cover (screws at rear of appliance)
and left-hand side panel (screws along top, at rear
and underneath appliance) from the appliance.
(1) Pull out the drainage hose connector from the
pump cover.
(2) Remove the pump cover(s)
(3) Remove the nut on water level sensor to
allow the water level sensor to be removed
from the pump cover. Unclip the wires.
3. Disassembling the door
1) Remove the screws holding the hinge to the front
panel. Lift the door to extract the hinge from the
panel and place on a soft surface to avoid scratching
the door.
2) Remove the screws on the inside of the door.
3) The door should now be able to be stripped into
its constituent parts.

4) Push the two pins of the hinge to separate the
hinge..
4. Disassembling the heater
1) Remove the screws from the rear panel
2) Remove the screws from the air ductwork below
the heater
3) Remove the top cover by unscrewing the screws
at the back of the appliance.
4) Disconnect the loom harness from the RFI filter
5) Disconnect the terminal from the heater connector

6) Remove the cable clamp holding the wires to the
backpanel
7) Remove the screws from the heater
5. Disassembling the drum
1) With the side panels and the top cover of the
appliance removed, remove the bracing struts
between the front and backpanels. Remove the
screws which hold the metal backpanel to the plastic
base. The drum and the backpanel should now come
away as one item.
2) Remove the main drive belt from the drum
subassembly.
3) Remove the two screws from the bearing cover
4) Remove the ring seal from the bearing cover

5) Remove the nut with adjustable wrench or similar
6) Remove the drum shaft ring
7) Remove the backpanel from the drum
8) Remove the other two shaft rings
