I think I have discovered an easy way/workaround to do just 1 rinse without fabric conditioner from the autodose system .
set dial to 'outdoor' - long press the rinses option and select 1 rinse, then set your spin speed. then press start. it shall do a 20minute rinse and spin.
outdoor cycle tells the washing machine not to use fabric softener for that particular wash program
Its just a bit quicker I find than going into the 'options menu' and pressing the dose per rinse to 'off' and then maybe forgetting to turn it back on again for the next wash cycle which is easily done.
