The pumping out is not a timed operation, the pump runs until the machine is empty.

bzzt wrong answer

Can you expand on that please? I ask as on the few machines I've used
the pumps seemed to operate until the machine is "empty"[1], not for a
timed period. My main evidence for that is their behaviour (a) when
used on different cycles with different water levels; and (b) when used
to spin stuff put in wet, or to spin after being paused. In those circs.
the pump operated for a varying periods before starting the spin cycle,
not for a fixed time.

[1] taking empty to mean "negligible more water can be pumped"

Washing machines don't normally have a water empty sensor, so they just pump for enough time. But I wouldn't be too surprised if they've started monitoring pump current now to see when to stop, saving energy, but I've never had one that does that.

They do have an empty sensor to ensure the heater won't come on when the machine is empty.
