DAEWOO ELECTRONICS DWF-5550 - Softener Dispenser; Automatic Unbalance Adjustment; Circulating-Water Course and Lint Filter

AUTOMATIC UNBALANCE ADJUSTMENT
This system is to prevent abnormal vibration during intermittent spin and spin process.
FUNCTIONAL PRINCIPLE
1) When the lid is closed, the safety switch contact is
"ON" position.
2) In case that wash loads get uneven during spin,
the outer tub hits the safety switch due to the
serious vibration, and the spin process is
interrupted.
3) In case that P.C.B. ASS'Y gets "OFF" signal from
the safety switch, spin process are stopped and
rinse process is started automatically by P.C.B.
ASS'Y.
4) If the safety switch is operated due to the
unbalance of the tub, the program is stopped and
the alarm is given.
CIRCULATING-WATER COURSE AND LINT FILTER
CIRCULATING-WATER
The washing and rinsing effects have been
improved by adopting the water system in which
water in the tub is circulated in a designed pattern.
When the pulsator rotates during the washing or
rinsing process, the water below the pulsator vanes
creates a water currents as shown in figure.
The water is then discharged from the upper part of
the tub through the water channel.
About 40L/min. water is circulated at the 'high' water
level, standard wash load and standard water
currents.

SOFTENER DISPENSER
This is the device to dispense the softener automatically by centrifugal force.
This is installed inside the auto-balancer.
FUNCTIONAL PRINCIPLE
1) Softener stays in room (A) when poured into softener inlet.
2) Softener moves from (A) to (B) by centrifugal force during intermittent spin process.
3) Softener flows from (B) to (C) during rinse process next to intermittent spin.
4) Softener moves from (C) to (D) by centrifugal force during second intermittent spin.
After spin process is finished, the softener is added into the tub through softener outlet.
FLOW OF THE SOFTENER
FLOW OF THE SOFTENER INSIDE OF THE BALANCER
NOTE: Softener moves into the next room when r.p.m. of the tub is more than 100 r.p.m.
HOW TO CHECK MOVEMENT
Pour a reasonable amount of "MILK" into softener
dispenser and operate the washer with no load. In final
rinse cycle, make sure that the milk is added into the tub
through softener outlet.
