Cool-down, Permanent press program

For cool-down during Permanent press programs (60°C and 95°C), cold water fills the machine until water temperature falls to 56°C. The main wash water then drains. Water fills in pulses for Permanent press programs, while for Normal programs, it fills continually. During the former, the water valve is open for 3 seconds, closed 27 seconds, open 3 seconds, etc.

Cool-down at program stage 21 occurs as follows:

•When the timer reaches stage 21, it stops (this stop is preset in the timer).

•At program stage 21, rows 14a (1), 11a (5) and 6a (7) are closed. Row 3 (2) in the program selector is energised during the permanent press programs and the level control (3) is set at position 11- 14 (the drum is filled to low level).

•This means that water valve Y11 (9) and row 22a (6) now open and close at the same time — 3 seconds open, 27 seconds closed, 3 seconds open, etc.

•When the temperature falls to 56°C, the thermostat 60°C-contact

changes over from position 31-34 to 31-32 (the thermostat has a hysteresis of 4°C, see also chapter 27, type 10). Since rows 1a (4) and 39 (10) are closed at stages 21 and 22, the coil (11) for rapid advance receives voltage causing the timer to rapid advance to stage 23.

•At stage 23, the water-filled drum rotates for 0-1 minutes

before the water drains at stage 24 (time can vary since the timer advance is synchronised at stage 23 with the program pause).
