Zanussi IZ16 rinsing
On my machine, a small load just gets tumbled during the first two rinses, occasionally interspersed with distribution speed tumbling. Jetsystem operates all the time during the rinses, except if...
...the drum is fully loaded (jeans, towels). In which case the action is as mentioned above, plus additional action of low level spin bursts, for 5 seconds at a time.
When the spin bursts section of the programme is identified by the machine, the jetsystem pump stops for a second, then resumes.
The spin bursts DO create a creamy froth that seems to be difficult for the machine to pump either to the jetsystem, or to drain.
