A Warning and Safety Instructions
1 General Information
Danger!
Danger of high voltages when working on small components.
In a single-board control, as in this appliance's electronic (EPWL 3xx),
there is no structural galvanic potential disconnection to the power supply.
Therefore, be careful when working on small components, as they may
be carrying voltage if the dryer is not disconnected completely from its
power supply.
Components with sharp edges may stick out. Wear protective gloves and
goggles and use edge shields to prevent cuts by sharp-edged components.
Note:
All repairs should be performed by a trained technician in strict
accordance with national, state and local codes. Any repairs or
maintenance performed by unqualified personnel could be dangerous.
When servicing, modifying, testing or maintaining appliances, all
applicable laws, regulations and accident prevention guidelines must be
observed.
After work has been completed, a visual as well as an operational check
should always be performed.
After work has been completed, do a touch current measurement on
machines with a ground connection on all accessible conductive parts
that are not grounded.
Before starting any service work, disconnect the dryer from its power
source. Even with the appliance switched off, voltage may exist on some
components.
2 Fire Danger due to Excessive Lint
Danger!
The dryer must not be operated if there are leaks in the air shield, such as
those caused by a defective seal.
If the dryer is operated regardless of these leaks, this will result in heavy
lint in the appliance interior. Moisture can make this excessive lint soggy,
which will lead to electrical short circuits and possibly fire.
Indications of excessive lint: a poorly maintained dryer, long running time
(fixed maximum time has been exceeded), water under the fascia panel.
Remedy:

Technical Information

T 80xx
- Remove all lint from the dryer.
- Find and repair leaks.
3 Restoring the Ground Connection after Dismantling the
Front and Side Panels
The ground connection for laundry-care appliances is established via
screws: raised-head screws with teeth or serrated washers underneath
connect the ground lead to the interference-suppression filter, the front
panel, the side panels and the housing frame. These screws are different
from the rest of the appliance screws in their diameter, type of thread, and
type and material of the washer.
The ground connection is made only if the ground screws are screwed
into their correct positions during reassembly.
When dismantling the front and side panels, mark the positions of the
ground screws. During reassembly, screw the ground screws into these
same positions.
To check the proper screw positions, measure the resistance of the
ground connection loop.
