More Details on Dishwasher Water Heating

I ran a load this afternoon and monitored the cycle. The Kill-a-Watt meter is still connected, but I didn't check it before starting so I can't say how much power was used. This info is only in regards to time.

I cranked the water heater down to 50°F so the fills were tap-cold.

Kitchen faucet temp read about 82°F.

Normal Eco cycle.
88 mins initial time.
Wash (or prerinse), Wash 125°F, Rinse, Rinse 125°F, Dry.

88 Mins = Start

81 Mins = first drain. That makes the prewash 7 mins (no delay for heating).

78 mins = start of main wash fill

46 mins = main wash drain. That makes the main wash approx 32 mins. In my previous instances of monitoring the temp in the tub, the heated cycle phase ends within a couple mins of the target temp being reached. I assume there's a minimum time involved in case of a really HOT fill, but don't know what is it.

43 mins = first rinse fill.

39 mins = first rinse drain.

36 = final rinse fill

25 = final rinse drain. That makes the final rinse approx 11 mins, including water heating ... which was apparently aided by residual heat from the wash, even with a cold-fill rinse preceding. Still, 11 mins is much less than I'd expect.

Remaining time is drying.

Timing the cycle separately via the minute timer on my microwave, the full cycle was extended by only 3 minutes. At 25 mins remaining time on the dishwasher display, the microwave had 22 mins left. The dishwasher had 3 mins dry time left when the minute timer ended.
