"... a flush between each program segment."
I am assuming that it is a bit like my old Bosch.
After the mainwash, my Bosch drains the dirty water, then does one of two things:
- It seems to fill part of the water matrix, tap is turned off, then it pours that into the tub, circulation for a second or two and then drains separately a few seconds later. This is the most common sequence as far as I can tell, and seems to occur after each rinse, and most of the main washes.
- Other times (not always) it seems to open the tap and pumps straight out at the same time. Similar to someone constantly running a tap straight down the sink plughole. I've wondered whether this is a genuine suds or dirt flush, or whether it is really connected to water softener regeneration.
