Aside: I heard that "eco mode" is typically not actually the most energy efficient mode on most washing machines. Apparently it's a standard mode they have to add so that energy efficiency can be measured across machines, but that means it can't be optimised.
You're typically better off looking for some kind quick/fast mode. Or even the "regular" mode.

(YMMV, look things up for your specific model)
