Water filling
This section describes a machine which has a hot and cold water
connection. Program P02 does not use Pre-rinse (stages 1-3) which means
that the timer rapid advances past this section, see function section "Rapid
Advance, Program Selection". Here is how water fills in other wash
sections:
Prewash
During the prewash cycle row 5a (2) is closed which means that the water
fills to the high level (the change-over contact 21-22-24 in the level sensor
trips at high water level). Row 4b (5) is closed which means that cold water
fills detergent compartment 1 with water valve Y11 (13). Row 2b (7) is
closed and warm water fills directly into the drum with valve Y24 (17) in all
programs except Cold, since row 7 (12) in the program selector is closed in
all programs except Cold. Rows 5a (2), 4b (5) and 2b (7) are closed during
the entire prewash. If the water level during prewash falls below the level
sensor's preset level, water will refill (see chapter 26 on Level Detection).
Main wash
During the main wash row 3b (1) is closed. Water fills to the low level
because the shackle N (3) on the parent card is cut but to high water level if
the shackle is closed. Voltage travels from the level sensor via row 8a (6).
The program selector's row 5 (9) is closed during program. Hot and hot
water fills detergent compartment 2 with water valve Y22 (14). During other
wash programs the program selector's row 6 (10) is closed, and then cold
water fills the detergent compartment 2 with water valve Y12 (15). During
all programs hot water also fills directly into the drum with the water valve
Y24 (17) since row 2b (7) is closed during the main wash. The rows are
closed during the entire main wash which means that if the water level
during this cycle falls below the level sensor's present level, water will refill.
Rinse
During rinse cycles, row 3a (1) is closed which means that water fills to high
level. Row 4a (5) is closed and valve Y11 (13) fills detergent compartment
1 with cold water. Row 6b (8) is also closed which means that if shackle P
(11) on the parent card is closed, valve Y24 (17) receives voltage and
warm water fills directly into the drum. For the fourth rinse, row 2a closes as
well so that valve Y13 (16) can flush away any conditioner used from
compartment 3.
