Yesterday I purchased a new DU945 since I heard that they went out of production and everyone says it's a great model. I will replace the original dishwasher that was in my townhome, which is a Whirlpool basic model, dial control with Pots&Pans, Normal, Light and Rinse&Hold dial settings. The original is a white plastic wash arm, with a tower that comes up through a tube on the lower rack to wash the upper rack. I had originally planned to have Lowe's delivery and install my new machine, but they started rolling it out to me, so I simply loaded it into my Explorer and brought it home with no provision to install it, so now it's in the original box in garage until I muster the guts to attempt an install. Anyway, last night I searched out an online manual to see if there was a description of the wash cycles. I found it, (the link is posted). The manual does have cycle descriptions but it lists something called "purge." Does anyone know what a "purge" process is, verus "Rinse?" Thanks! CLICK HERE TO GO TO llmaytag's LINK |

Leonard, Greg's above-description is right on for a modern whirlpool Tall Tub, but isn't correct for your model. Your dishwasher, a purge is a "rinse" that's between the main wash and the final rinse. This purge has a partial fill and sprays little bit of water over the dish load for about 10 to 20 seconds and then drins said small amount of water. The small amount of water is about 1/3 to 1/2 the amount needed for a regular fill. This gets some soap off the dishload and cleans the filter. This is also common on the TallTubs that don't sense extremely heavy soil or if the Pots & Pans cycle isn't used. In those two scenarious, a true full-filled rinse is executed instead of the purge, thuis yielding 2 rinses. NOW, note, your manual says that high-temp wash option adds more time, heat and water. The added water is the purge is replaced by a full rinse. Personally, I've not found any issues with rinsing on my tall tub when the purge is used rather than the fulll-fill rinse. And Greg, btw, I'd not heard abut that intital load completely "setting" the sensor. I did know that that first load did do the equiavelnt of an extremely heavy soil because it added the full risne rather than the purge. And if that first wash cycle was interrupted (i.e. cancel button hit before it finished to the "clean" light, then the sensor would not be "set". I also understand, periodically that sensor readjusts itself based upon input about water hardness and average soil in loads. My BobLoads are 99% of the time very veryr soiled. |

Our Siemens does that, too. Depending on the soil level, it'll drain, stop and then turn the recirc pump on while filling for maybe 15 seconds. Purges take place after the main wash and the first rinse - if necessary. Heavy soil replaces the purges with another full rinse. It doesn't need to do a cool-down because the first rinse always starts with pre-heated water from the heat exchanger. It also starts by spraying the bottom rack first so the water heats up even more before it is sprayed onto the upper rack. The Miele will do a partial fill after the main wash, spray for 5 secs and then continue to fill. It also pre-heats the water. |

Toggleswitch2 - Thanks. I've been telling myself that it shouldn't e that hard to install so I may attempt it next weekend. It looks like it will be pretty easy to rollout the original after I remove two small screws at the top that I think simply hold it in place. From the manuals of all the new machines it looks like most do a "purge" after the main wash, then one rinse. My original did two rinses after every cycle, (a dial machine), and often when I'd hear the final rinse finish filling, I'd turn the dial back to the beginning of the first rinse, so I'd get three. I'll have to get over that with the new machine, lol |
