Mechanical and electrical design
Door
The door consists of: a door skirt (1), door (2),
glass (3) and gasket (4). The frame skirt and
door frame are both made of enameled alumi-
nium. The skirt is bolted directly to the outer
shell of the washing machine.The door hinges
are fastened on the outside of the skirt and the
door lock (5) is attached to the inside. The heat-
hardened glass is mounted in the door using a
special rubber seal which also acts as a gasket
between the door and the washing machine’s
outer shell when the door is closed.
Door lock
The door lock consists of a circuit board (1) with
a connector. Mounted on the board are the lock
plate (2), against which the locking bolt turns to
lock the door, and a microswitch (3) which closes
when the locking bolt has locked the door.
There is also a locking device on the circuit board
which acts to lock the locking bolt in place when
the machine starts up.
The locking device consists of a double-acting
solenoid (4), a delay unit (5) and the locking
device itself (6) which operates sideways in
blocking the locking bolt with a stud. The locking
device can be affected by both the solenoid and
the delay unit.
The lock operates as follows:
• When the door is shut and the locking bolt
moved to the lock position, the micro switch
will indicate that the door is closed.
• When the machine is started, the solenoid
actuates the locking device, blocking the door
lock. The locking device signals the delay unit,
closing a switch in the unit. The washing
machine motor will start and water enter the
machine only after the delay unit receives the
information that the door is locked. The bi-
metallic spring in the delay unit is warmed up
at the beginning of the program.
• Once the washing machine stops at the end of
a cycle, the solenoid pulls back the locking
stud and allows the door to open. The delay
unit is spring-mounted in the locking device
and is also pulled back by the solenoid, which
operates for about two minutes to allow the bi-
metallic spring to cool down enough not to
lock the door again.
• If current should disappear during a cycle, the
delay unit will keep the door locked for about
two minutes, ensuring that the wash water can
drain out (The drain valve opens automatically
when current is lost).

NOTE
Do not attempt to repair a faulty
door lock. The individual
components are not available.
Always replace the old unit with
a new one to assure proper
operation of the door safety
interlock.
