@gorenje:
Thanks, the Panasonic is okay-ish - but to be honest, I expected a bit more quality.
The optical sensor on mine only really seems to detect during the wash. Therefore powders in solution are seen as opaque, lengthening time; liquids generally are seen to be transparent, reducing time.
For rinsing, I think the machine logs the inability to redistribute - and adds a dilution rinse. If the water is too foamy, I think the pressure vessel/sensor detects that, and adds a dilution rinse. I've never gotten the impression that the optical sensor actually had a hand in the rinse decision making.
Things I do like:
> Mixing of detergent by distribution tumbles;
> Powder drawer stays closed - even on violent spin cycles;
> Zero-delay door interlock;
> Large, very easy-to-read display;
> The idea of wash solution recirculation...;
> Filter compartment has a pouring spout (previous Panasonic dribbled water down between the kick-plate and the machine itself).
Things I don't like:
> Attempting to redistribute the load for spinning is irritating;
> Programme times;
> Spins can be a bit violent;
> A small shard of concrete came adrift(!);
> The filter access panel rattles - and would benefit from a Bosch style thumb-release catch - having to resort to screwdrivers to open it is madness;
> The recirculation implementation could have been better executed. This one has a common manifold with three outlets. They have a tendency to clog with lint.
