Differences in 9810 & 7811

The only thing I miss about my old dishwasher is the countdown timer, and bar graph display on the front that showed exactly where it was in the wash, the rinse and the dry. The 9810 has the display on the top by the hidden controls thus it is hidden during the cycle. The only way to see it is to open the door. Also the vent is on the left side of the door at the bottom, so it vents hot steamy air on the floor. A pool of water forms on my tile floor during drying in front of the dishwasher. After an hour or so it dries. I hope you don’t have wood floors.
 
~Cutlery & Silverware trays…

The top cutlery tray comes out if you need more room in the top rack or you can take out the tray on one side or the other. Each side can be rotated independently to accommodate deep utensils or give more room on the top shelf (Shallow utensils). The top rack also adjusts up & down.

My other half is a Chef and sometimes he does not scrape things and never rinses anything. I’m not sure if it’s because of the steam, or the way the utensils all sit in there sideways, but cutlery on the top gets clean. The tray also comes out easily when full so you can take them to the silverware drawer and unload them.

The other silverware tray comes apart in 3 pieces. We only use 1 piece which can go in the top or bottom rack. Sometime we don’t use any of the pieces (Just the top cutlery tray).
 
~Cleaning & Detergent…

The cleaning is AWESOME! With a Chef in family we have a lot of very dirty dishes. Sometimes he puts pots in without scraping them out and there can be goop that drips all over the door and in the bottom of the dishwasher and everything still comes out clean. We mostly use Cascade Complete Powder, but we are American so sometimes we get lazy and use Cascade Extra Action 2 in 1 Action Pacs (Blue and white tablets) when we don’t feel like lifting the box.
 
~Cycles & Options…

I’m like George and I like pushing buttons, so I usually use SOAK, with STEAM, EXTRA RINSE, and SANITIZE. Sometimes I get creative and put wine glasses on the top rack and pots and pans on the bottom. You can set the water pressure to soft, medium, or strong for the top rack and bottom rack independently (Soft on the top and strong on the bottom). The Chef just hits NORMAL and SANITIZE no matter what’s in there. Amazingly everything still comes out clean and dry. The coffee pot handle always has water left in it. There are sometimes particle in the water that’s left in the handle after the Normal Cycle, but we’ve learned to dump the water in the sink. After all of these years you’d think they could design a coffee pot with a better handle.
 
~Sensors…

There is a senor that tests the water and a microprocessor that sets the temperature, the pressure of the sprays, and the number of fills. The temperature and number of fills is set within a range for each cycle (Example: Normal will heat the water from 113F to 140F and fills twice or 4 times depending on soil). The water spray pressure has a min. and max. according to the cycle and the strength you choose (Soft, medium, or Strong), but it also varies based on the soil level. By setting the cycle and the strength you are setting the range. The soil level actually determines the pressure.
Sprays alternate between the top and bottom rack, but it’s so quiet that it’s hard to tell how long it sprays on each. I first noticed this when our counter tops were being replaced and there was nothing on top of the dishwasher. It will pause and then spray from time to time to test the turbidy of the water and decided to drain or wash more. It will also drain then continue to wash, then drain and then fill a little while draining, perhaps to purge the water.
 
~Connected to cold water…

It can be connected to hot or cold water. Ours is connected to cold water. The cycle times are about what the owner’s manual predicts. We did try it connected to hot water, and the cycle times are quicker. But even if it was done cleaning the dishes before I was done pushing the button; I still would not put the dishes away until the next morning. We cannot justify having it connected to hot water, because by the time the hot water reached the dishwasher; the dishwasher is done filling. The hot water just sits in the line and is wasted. The hot water in the line has cooled down by the time the dishwasher fills again (It uses very little water).

It’s better than our previous dishwashers which were a Maytag DWU9962AAE (The first Maytag Dishwasher w/ a sensor) and a 1997 GE Potscrubber 900 Dishwasher GSD900D-03 (w/ temperature senor in Black)

Eugene, I know you’re gonna love it!

Thanks for all the info, Jeff. It instills some confidence over my spendy purchase! I can't wait for the dw to arrive. I, like you, usually only use a small portion of the silverware basket, and I like having the option of putting it in the upper or lower rack. I'll probably use the half-load option a lot---at least I did when I had a Frigidaire with that option.

I'm mostly excited to have a dw that will be very quiet. I work in the kitchen with the machine running, and friends tend to gather in there while I'm doing prep work (my social life revolves around having people over for dinner).
