D&M
This is a D&M machine, the water still needed to be at least 140 degr.F.,and the cycle consisted of a spray from above with drain open to flush loose soil away and warm things up, a 10 minute wash, another spray from above, two rinses, and a 16.5 min.dry ,impeller now acting like a fan to blow heated air .The overhead sprays were from the fill valve, not pumped at those times, and,for efficient cleaning,most impeller machines required at least eight plates evenly spaced to deflect the water straight up to the top rack.This was the best impeller DW for one reason, the upper rack ,driven by water action made sure that all upper items got washed, even if some of the bottom rack had pots, big bowls, etc.By the way, the heating element would stay on thru the whole cycle,thus the water temp would go up slightly, but a 10 minute wash would only cause a 10 degree rise.
