I just purchased a Bosch 300 Nexxt front loader and it washes great! I noticed that it has a triangular spray nozzle at the top opening of the door in the seal and then another round protrusion to the left of this nozzle on the seal which looks like it could spray water also. However, nothing comes out of these nozzles during the wash, rinse or spin. Are these nozzles used on upper line models, like the 500 or 700, but not on the 300? Just wondering if anyone knew. I've been using the Kids Care cycle to disinfect towels and wash clothes since it gets to 150 degrees in the wash water (same disinfect temperature of Whirlpool HE3 models)...great feature.
