Ardo A633 drains normally, but not at the end of the program

Tried asking it on another site, to no avail. Also went through the FAQ. Does not seem to resemble anything mentioned there.

Ardo A633 (front load, mechanical controls) drains and refills normally during the run but often (not always!) forgets to do the final drain when it's done, ending up with the drum half full of clean water. Sometimes it remembers to drain when I re-run the rinse cycle, sometimes I have to wait for the next day to do it. No system whatsoever. Of course, the "no drain" button is not pressed.

I don't think the problem is either mechanical or electrical - draining works almost always, just not when it's most important. I'd say it is a control board firmware bug, but the washer has mechanical controls and, likely as not, no firmware whatsoever. An expert advice would be appreciated.

Does it have a crease guard function? Many washing machines have specific wash cycles, or an option button, that leaves the laundry suspended in water prior to the last spin. This is usually for delegates laundry where if the washing machine does the final spin and the laundry isn't removed promptly they will end up badly creased.

So by suspending the last spin until a user is ready, the laundry is held in water until the user presses a button to start off the final drain and spin and then presumably remove the laundry when it's finished.

Its manual says nothing about any crease guard function. The closest thing I could find is a "no drain" function; I tried turning it on and off, no difference.
