3.6 Door springs
3.6.1 Door spring operation
Fig. 22: Door spring system
The door spring mechanism uses a "sliding" pulley and cord to provide proper tension
and enable self-closing.
¡
The fixed sliding pulley slides onto the base and is held in position in tension by a
spring. The cord slides on the pulley, using the friction between it and the cord to
provide better control.
¡
The back of the spring slides into a slotted pocket in the side of the base and the
front of it connects to the cord. Springs are color coded for specific tensions.
¡
Bases and cords are new and aren't backward compatible (i.e. with older dish-
washers).
Service calls have occurred from customers with dishwasher doors
without wooden panels installed. Door springs are chosen to support the
weight of most wooden panels – doors without panels are too light and
close on their own.
3.6.2 Door spring changes for Push to Open / Auto Door Open
To add Push to Open and Auto Door Open (to some models), changes were made to
the door spring system for all dishwashers.
¡
Hinge cords (4) and door springs (2) are longer.
¡
The base (6) is new to allow for the longer hinge cords and door springs.
¡
New hinge cords, door springs and bases aren't backward compatible (i.e. with
older dishwashers).
¡
There is a new spring guide (3).
¡
Hinge levers were changed where hinge cords are attached.
