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.
