Gansky1....

I guess great minds think alike...I was going to do exactly what you did with my Reverse Rack and do a glass in both the upper and lower rack. Well it just wouldn't be any fun if I still didn't do the test next load around, I guesss we will find out of there were any improvements with the direct drive pumps.

Peanut Butter Test # 2 (24 hour dried peanut butter)

this time with the Jetclean/steam cycle. I chose EVERY option, hi temp, tough scrub, steam sanitize and I think this cycle uses a TON of water. When I opened it more steam came out that I have ever seen in my life from a dishwasher. The cycle ran over 3 hours! Before when I ran the jetclean steam cycle, I had not chosen steam sanitize, but this time I did.....there wasn't a trace of peanut butter anywhere, the glass smelled clean and no peanut butter smell in the dishwasher.

Just think of all the water, energy, time, and wear and tear on the machine (running for 3 hours) to get some peanut butter out of a glass. I just pray my old non-HE dishwasher last forever.
 
Actually, time is the only factor that comes into play. New dishwashers have such tiny pumps / motors and use so little water (usually only 3-4.5 gallons) that the 3-hour cycle still uses substantially less energy and water than a vintage machine.

I often use the Light (49 min.) or even Express (30 min.) cycles on lightly soiled loads. But on the Normal or Heavy cycles, time is where new dishwashers can't compete with speedy vintage machines.

Mark-- Success! Using the JetClean cycle was probably the key to better results. Steam Sanitize: Did you notice if the machine stopped and just steamed for awhile? My LG used to do that when the Steam option was engaged. The GE pauses and just runs the four bottle wash jets when the Bottle Wash option is selected, which is probably why the cycle is lengthened by about 20 minutes.
 
TWELVE GALLONS? Most new machines use .75 to 1.25 gallons of water per fill, made possible by alternating the spray between racks. That would mean 10+ changes of water. My new Maytag washer uses about 10 gallons to wash an average load of clothes!
 
Actually, Mark's Maytag, while basically new, wouldn't be technically considered an HE dishwasher, because it's of the Voyager build, just with improvements to cycle management that help it use less water and energy than the older Voyagers do, as it was built alongside the new Whirlpool Tahoe/Resource Efficient/"whatever their codename is for it" design. I'm not even sure the new Maytag design could be considered HE, because while it is built on the Tahoe platform, the removable filter is instead an accumulator filter in the same sump area, and the motor is a smaller version of what is in the Voyager, but more powerful than the PM motor in the removable filter version, and there is no diverter valve, so the fill level is about the same as the Voyager, maybe slightly lower.

Mark - Your steam cycle is probably a bit more effective than in my Maytag, since yours is the high end stainless steel model, and the element is set into the sump. In mine, the tub is plastic so the element is raised so my steam option always filled up to that point and would sit, heating the water, and would pulse the motor every now and then. It would then dump all that water and go into the final rinse. It was basically a longer version of normal Sani Rinses.

The new Whirlpool now has the element mounted down against the bottom, so I think it helps a ton with heating water more efficiently, but the water level is also barely outside the border of the sump, so I'm sure that was the main reason for doing that in this case.

Frigilux - These are always my go-to choices for being flabbergasted, haha 😐 😦 😶
 
Yes -

that was a LOT of water/energy to get peanut butter out of a glass. I agree. But it was just a test is all. Since the autoclean was a fail, I needed to know if my dishwasher could "do it" on at least one of its cycles.

I searched and found the old topic back when my other 9.2 yr old dishwasher was drying a horrible death and I posted a video asking what was wrong, then it died just after I posted and continuing onto the new Maytag and install nightmare.

 
On my maytag, I'd run the auto clean with high temp wash and steam sanitize, no heated dry. That was my default cycle, unless I was using the machine mid-cooking session then it was quick wash. I really didn't use much else.

I should have ran a PB glass through before I took the maytag out.
 
I was too lazy to put peanut butter in a glass, so when the peanut butter jar was empty I just put that in the dishwasher. It's narrow anyway.

This was 100% peanut butter, no salt, sugar, oil or fat addded. It's crunchy, the best peanut butter I ever ate. Easy to make yourself too, I think I am going to give it a try soon.

The load is not a 100% Bob load, but it's pretty full. Peanut butter jar in the corner of the top rack. Everything got clean and no peanut butter smell in the dishwasher. Dishwasher is a Miele G4210SC. Detergent is Somat 10 tab.

Very Good Louis.

 

And I just threw away a empty jar of Peanut Butter. Darn !!!

 

Does the end of the Spray Arm on the bottom of the Upper Rack have that long slit at one of the ends ?  It's amazing how quiet those Miele's are and cleaning is stellar.
 
Not quite PB...

So, this morning, I had a load ready to go, and thought why not try it out? Sadly, I recognized that I'm actually living a somewhat healthy lifestyle (not that I actually would do, LOL) and there is not one thing in this house that could be used as a substitute for PB.

So I used 2 glases, one tall, one shorter, both covered in toothpaste, the shorter sprinkeled with choclate drink powder, dried in by spending 30sec in the microwave and 1 1/2 minutes with our hairdryer.

That load in the bottom rack wasn't blocking the spray a lot, but at least a bit.
Cycle was Auto, store brand tablets (~30% phosphates).

Everything came clean, except for a plastic cup that flipped over and accumulated the drink powder.

Sorry for the bad lighting, it was early and my tablet has no flash.
Not a comparabel test, but worth a try.

Great results guys -

what a great idea waiting for the peanut butter glass jar to be empty to wash it. I couldn't have done that because the peanut butter I use is in plastic. But natural peanut butter is best. I use smart balance or Costco Kirkland Natural....sometimes Jif Natural. Now that would be a REAL TEST, an empty peanut butter jar that has had peanut butter glued inside it for who knows how long (from the factory!)

@ Andrew - Thanks for the info

@ Frigilux - I know right! Who would have thought? As far as the steam cycle, I do not know. I wasn't in there when things were going on
 
Thanks guys!

Yes Eddie, it has that long slit and the upper arm reaches far enough to get under the jar. I made a picture of it with my iPad, hopefully you can see it in the picture.

My Miele is a BOL model. It's actually louder than my previous one, an AEG (48dB vs 45dB), but I can live with that. It's a freestanding model, there are no cabinets around it to dampen the noise.
