Was browsing on ABT's site and they've just added some JennAirs that look like a revision of the current line of Whirlpool DWs.

This model is akin to the KitchenAid 200 Series or the Whirlpool 750/A50 series. It looks to be nearly identical to the prior JA version, except- and I think very excitingly- it has door-open drying. Previously only their euro-import models had this, but those have smaller interiors (I think). Cool to see them adding it to the larger-tub models. I'm sure it'll be in the WP/KA/MT equivalents soon.

Model is the JDTS3924SM. Linked below.

Found an unreleased model number…

Playing around on their service site’s guest search I found an unreleased model WDTS8024SX (X being the color code placeholder). The installation manual listed for it (no cycle guide or parts diagram yet) lists auto-open doors as one of the sub menu options (with the caveat of being model dependent). Given they just released an updated premium model in 2024 (WDTS7024RX) I’m going to guess in the WP branded line they’re going to save the auto-open drying for the top model.
 
Wasn’t the global wash wash the previous system used in the main models up until 2020? And it’s now related to the budget models.

The wash system, on a glance, looks unchanged.
 
Since Jerome only deals in marketing jargon, the newest Whirlpool dishwasher platform, that has the rectangular shaped sump, and much taller tub space, has been called the "Eco Series" when it has the manual filter cup.
This filter cup layout I've seen so far on all Whirlpool models, the lower end KitchenAid models that have the letter "E" in the prefix. As well as the JennAir series since the filter cup system is quieter, with smaller pumps.

The outgoing "Global Wash" or sometimes called "Resource Saver" dishwasher platform we know for many years now, is only on a couple budget model Whirlpool dishwashers, since those tubs are not as tall.
 
Interesting to know of the name of this series, thank you!

On another glance it looks like the only change they are making to their wash system is swapping out some of the pumps used in Whirlpool brand models. For instance, the WDTS7024R* (a revised version of the WDT970SAK*) has an 80 Watt Hanning motor now instead of the prior 31 Watt Hanyu motor (that had a 20/10 duty cycle). Based on the cycle guide, I’d also wager it’s not being run in a variable speed mode versus the KDTE204KP* that uses the same motor. If I had to guess, they were seeing a failure rate higher than expected and it wasn’t worth the cost savings. The biggest knock I see in user reviews of these WP wash systems are early pump deaths.

The only other changes to this model are no folding tines in the second row and a cheaper-looking silverware basket, so obviously they looked to keep a similar profit margin.
 
Variable Speed Motors

@henene4, I've inferred this from the part numbers and the cycle guides they published for some models. I am confident in my assumption.

Yes, their current efforts are documentation are shockingly bad- it seems like most models don't have an owners manual at all, some have a quick start guide, and some have a cycle guide that shows you cycle information/time, options, and water usage.

Many of the cycle guides have flat out incorrect or incoherent information as well, in such a way that you can infer it was a rushed copy + paste edit that resulted in the mistake. I have no clue how they've let that get so bad, but they have. It's a shame because otherwise I consider their current line of dishwashers to be well designed, good performing for their price, and extremely serviceable. So they should be capable of decent customer-facing documentation as well.

Back to my point- from the cycle guides available, models with variable speed wash pumps have "Heavy" cycles that have shorter wash times than the "Normal" cycles. Sometimes the "Sensor" cycle is shorter as well. I've also looked at replacement motors online and checked the photos to see which have 2-wire vs 3-wire harnesses.

Lastly, their tech sheets for models seem to be generally correct, as the tech sheets for Variable speed models have a variable speed motor indication (with the not on all models caveat), but single phase motors just say Single Phase on their tech sheets.

In the revision I mentioned above, the whirlpool model has single phase motor mentioned in the tech sheet but uses the same part number as models that definitely have a variable speed motor.
