I have sometimes filled the tank through the drain hose using a funnel at the end of the hose. Drain it as you normally do. The "old" tanks that I have usually hold about 1,800 ml. I would guess that the "new" tank holds slightly less. If the spindle won't go up and down, perhaps spinning it would work for agitation.
