Water filling
This section describes a machine which only has a cold water connection. The
diagrams of other variants (• cold and hot water • cold, hot and cold-hard water •
cold and cold-hard water) are included in the machine circuit diagram.
Here is how water fills during the various wash moments:
Prewash
During the prewash cycle, rows 14a (1) and 6b (7) are closed. For Normal and
Permanent press programs, row 3 (3) in the program selector is closed which
means water fills to the preset low level (the change-over contact 11-12-14 in the
level sensor trips at low water level). For Mild 30°C and Wool 40°C programs, row 5
(4) in the program selector is closed. The machine then fills to the preset high level.
Voltage travels from the level sensor via row 6b to water valve Y11 (11) which in
turn fills detergent compartment 1. Rows 14a (1) and 6b (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 Control).
Main wash
During the main wash, rows 14a (1) and 2a (6) are closed. Which level sensor (high
or low) is used depends on the selected wash program just as it does for prewash.
Voltage travels from the level sensor via row 2a (6) and rows 6 (9) and 7 (10) in the
program selector to water valve Y12 (12). This valve then fills detergent
compartment 2 with water. The above mentioned rows 6 and 7 are used to select
between the various water connections when cold water is not the only option.
When only cold water is connected, the rows are connected in parallel when cold
and hot water or cold, hot and hard water connected clamp A is cut. Rows 14a (1)
and 2a (6) are closed during the entire main wash which means that if the water
level during this cycle falls below the level sensor’s preset level, water will refill (see
chapter 26 on Level Control).
Rinse
During all rinse cycles, row 10a (2) is closed which means that water always fills to
high level. During the first two rinses, row 6b (7) is closed and valve Y11 (11) fills
detergent compartment 1 with water. During rinse 3 and 4, row 2b (6) is closed
instead of 6b. This makes it possible to select cold hard water for these two rinses
when other water options are available clamp B is cut. When only cold water is
connected, water fills via valve Y11 (11) into compartment 1. For the fourth rinse,
row 4a (8) closes as well so that valve Y13 (13) can flush away any conditioner
used from compartment 3.
