Hi guys, thanks for the posts. Really put it through its paces yesterday with my weeks laundry (anybody who's been to a wash-in with me knows how much laundry I seem to accumulate in a week lol).
The higher water level option is weird; it will add an extra rinse and uses a lot more water - however it will only do slow interim spins whereas on the standard cycles it will do a fast spin between each rinse. Can't complain on the wash and rinse results though, 80 minutes for a 40 deg wash and 3/4 rinses isnt bad for a machine of the "economical" age.
Darren - I haven't used the soaking cycle, however the display reads out 130 minutes when you select it. From what I gather on these Bosch machines it is a deep-level soak with intermittent tumbling.
The Aquaspa system is where the drum uses the paddles to scoop water up from the bottom of the load and shower it over the laundry at the top - encourages more water movement and therefore theoretically means you can wash a load with less water. Whether or not it actually contributes to washing results I don't know but it certainly brought up my whites really well. The Aquaspa system also uses different series of drum rotations depending on the cycle... one side of the paddles are rounded the other is angled, so on a cottons cycle it will tumble one way more using the angled side of the paddles (and hence stronger tumbling), whereas on delicate cycles it will tumble more teh other way using the gentler side of the paddles.
Cheers all,
Jon
