bad prelude to the wonderful reversa-jet
You wonder what was going through the minds of those at Tappan who approved and marketed this machine? The engineer who designed it must have been the CEO's cousin or something.
Apparently Tappan got the message and went from one of the worst dishwashers to one of the best with the Reversa-Jet. The Reversa Jet was over-engineered, I think in compensation and trying to get Tappan's reputation back.
The Reversa-Jet, in the 1965 Consumer Reports test, placed in the top group with the Kitchen-Aid, and Whirlpool.
Consumer Reports stated the Reversa-Jet cleaned up their aged soiled dishes perfectly and they said it would have given it their "Check-Rating" (highest quality and value) except it frequently tumbled glassware on the top rack due to the force of the spray from the upper wash arm.
I've notice many on this site confuse the Tappan "Dual Drench" with the Tappan Reversa-Jet. Goatfarmer's posting is a "Dual Drench" design with the name derived from the fact the drum reversed rotation during the cycle to wash on both sides of the racks.
The Reversa-Jet was a totally different animal. 18 place capacity, dual wash arms that reversed periodically in direction, self-latching door, lighted control panel, adjustable rack dividers and fine particle water filtration.
