Overheard a plumber at the supply house say he uses a $5 aquarium pump to test dishwasher drain solenoids
He said it mimics the real water pressure and you can hear the valve click, which saved me from replacing a good solenoid on a KitchenAid last Friday.

Water pressure" from a pump? That's just air flow.

Actually saw a video once where a guy explained how pumps work. They move fluid by creating a difference in pressure, not just pushing air. The impeller or piston physically displaces the water. Calling it just air flow misses the whole mechanical action. Pretty basic fluid dynamics, really.
