Of course I hooked up another set of hoses temporarily and did some further testing... The timer works great, and with unrestricted water flow, the machine fills, washes and drains normally. I also stumbled across the wiring diagram for this machine (also for SP40 and SP47 models - a picture of this to follow next week). I was puzzling about how the different cycles work on this dishwasher; hubby found a cycling chart as part of the wiring diagram!! The big difference from the older Mobile Maid I have - there are only two final rinses. Here's the cycles and their phases:
Normal Daily Dishes/Mixed Loads: prewash (no detergent dispenser for a prewash like in the 58 Mobile Maid), prerinse, main wash, two rinses, 16 minutes drying; water is heated in main wash and rinses.
Pots Pans/Utensils: 5 minute pause, prerinse, main wash, two rinses, 5 minutes heated drying, 11 minutes unheated; water is heated in main wash and rinses
Fine China and Crystal: 5 minute pause, prerinse, main wash, two rinses, 5 minute heated drying, 11 minute unheated; water is not heated in main wash or rinses.
Other cool features: the lid still pops open a few minutes into the dry phase, and the detergent cup will move back to the upright position during the dry phase of the cycle. How cool is that?? I am just DYING to run a load of dishes through this one!!
