Eugene, I ran that load of jeans this afternoon, with rinsing set at the "Eco AAAA" option. It does eight sprays total.
RINSE 1 PHASE --
300 RPM, 15-second spray
670 RPM spin-off
300 RPM, one 8-second spray & three 6-second sprays, spaced 20 seconds apart
670 RPM spin-off
coast to a stop, unlock/relock lid
RINSE 2 PHASE --
300 RPM, 15-second spray
670 RPM spin-off
300 RPM, two-7 second sprays, spaced 20 seconds apart
670 RPM spin-off
coast to a stop, unlock/relock lid
FINAL SPIN PHASE --
Interestingly, dunno why, maximum speed apparently is restricted to 670 RPM instead of 1010 RPM. I ran the final spin phase a 2nd time with ECO AAAA selected, and again 670 RPM max.
The Eco-AAA runs three sprays total, but they're much longer and at a slower 23 RPM, more of a saturation-spray than a spin-spray. I'd have to run another load to note the exact sequence.
