Speed Wash
Speed Wash
SPEED WASH is the quickest cycle that provides a complete wash
and rinse. It defaults to a 0:35 minute cycle. The default selections
can be overridden for wash temperature, spin speed, and soil level,
very hot water, and high speed spin, but certain options cannot be
selected. If a selection is not permissible with the cycle, the machine
will beep and refuse to accept the setting. SPEED WASH defaults to
a HOT wash, but most people find that overriding it to select WARM
gives a better wash and less wrinkling.
