Seeing as the "Money-Shot" is actually yours, Combo52, does your machine still work, or is it tucked away, waiting for a flood when the price of water goes down?
I think forced air drying is a far better idea in these - that way, you won't melt the plastic, the racks, dishes, or the wash-arm (if it were plastic).
Though I think some members have had better luck than others regarding their pop-up towers, it seems that performance is dependant on loading, like in single-arm KA machines - block the spray, and you are done for. It seems that GE's design was good, so long as it is loaded well, whereas other machines could handle "abusive" loading. I think my machine falls into line with GE - proper loading yields results, careless loading just doesn't work, or doesn't get the best results...
