The drain pump and the wash pump are two separate motors !

Captain Video said this one had no electronics, and a mechanical
timer. So, it has to be SERIOUSLY old! All the old ones had a
single motor/pump that was reversed to do both functions. Even our
much newer one with electronic controls only has one pump/motor
assembly.

Ours is a Philips "Wirlpool" dishwasher, UK made, it has a separate
drain pump. The main motor is a two pole induction one.

The only one that I've ever seen with a single motor would have been
30 years old or more, and that had a weird rubber flap valve with a
peg on it that was moved in one direction or the other by the
impellor blades themselves. The valve opened the drain port when
pushed one way and blocked it off when pushed the other.

The problem with this arangement was that if debris held the flap away
from the drain port, was that the machine would very slowly empty
itself.
