There is talk of how Whirlpool has gone downhill and I wanted to share my experience with my new Whirlpool dishwasher model WDT970SAKZ3 with the square pump housing. Here are some observations:

1. I like the 3rd rack, but obviously it take a third longer to empty the dishes when finished. It clean pretty well up there. I use it mostly for knives and spatulas.

2. I am pretty impressed with the fit and finish of the unit. The door spring components are pretty impressive. I guess one downside is the door handle. Whirlpool seems to have a difficult time make sturdy handles that don't loosen over time.

3. Installation was a challenge. The tub goes to the back wall of the space where it is installed, so I can't run any of the hoses behind the machine. Since the cabinet next to it is 5 inches off the ground, and the tub is 6 inches off the ground, I had just a very precise one inch space to run the drain hose. I had to run power and water through the framework on the side, which means I will have to remove it to pull it out. I hope that doesn't come too soon.

4. I am satisfied with cleaning performance, but some bowls don't get fully clean sometimes when they are nested together. I will have to figure out a fix for this.

5. I was not able to find a highly detailed owners manual. This leaves me wondering what are the differences between the cycles. One interesting anomaly is that sensor wash without water heat is timed at 3:26, while with water heat it drops to 2:31.I have been generally pleased with the quickest wash at 1:15. I am not sure what I achieve by choosing the longer cycles because the shorter ones seem to work fine.

6. Drying performance is adequate, although sometimes there is water on the top of mugs or dripping off plastic cutting boards. Some of that is to be expected, but I find myself having to do a quick wipe with a towel so that I don't drag water into the cupboard.

7. I am not thrilled that most repairs will require pulling out the machine. This seems to be a trend in the industry.

All in all, it is a nice dishwasher at a decent price. If I were to buy another or advise a customer, I would suggest maybe the one without the full handle.
 
If you can stack mugs on an angle/slant if your rack allows you to do so, so the water just runs off the tops of glasses and mugs. This is why I hate that every dishwasher brand got rid of those legendary upper tiered racks which eliminated this problem because every mug every glass on the top rack sat at an angle in each row, my older whirlpool came with that stupid standard flat rack and I changed it out with a tiered rack cause the pooling was ridiculous & it didn’t let me stack the cups on an angle as some racks will and now that problem is history

Jerome are you serious or actually just trolling at this point? I can’t even take you seriously. you have asked that dozens of times on here in multiple different threads and at this point it’s your own fault for not remembering something so simple. I would tell you again, but then tomorrow you’ll go and comment on another new whirlpool dishwasher thread and ask “what wash system does this have?”.
 
trolling

I'm not trolling. I wish Whirlpool would've stopped using those wet magnetic rotor pumps or even the variable speed pumps for the wash cycle and just stuck with the traditional AC pumps. Too many things to go wrong, too many electronics that shouldn't be there, and these wet magnetic rotor pumps are unsuitable for the wash cycle. They could burn out in no time. I want a real wash pump in my dishwasher. I prefer traditional AC induction motors. If it doesn't wash, I don't want it. I want strong jets of water blasting my dishes clean, not the stupid lawn sprinklers.[this post was last edited: 4/21/2025-10:02]
 
Sensor cycle

Odd enough, our newer KA is the same way. Time cuts down considerably with high temp added and heated dry on. Turn either off, and time jumps. Though, sensor/ProWash without heated dry is shortest. I imagine this is for Consumer Reports testing. Though, this doesn’t bother me as the machine is very versatile, cleans great, and holds a lot. Ours does dry well, though yours is not know to dry well. This could be a part of the reason for additional time.
 
believe those lengthened times are to assure an acceptable level of dryness....I note that on our Bosch machines if the rinse agent is low the drying time is extended.  Hotter the water---less elapsed time.

 

I just ran the 1 hour cycle on our 800-series Bosch....the dishes were perfectly clean, but were notably much hotter at cycle end than when there's 45+ minutes of condensation occurring (naturally)
 
My Bosch 800 temperature chart states the final rinse temp for the 60 minute speed cycle is 158F/70C. For Normal & Auto final rinse temp is 136F/58C. Heavy finan rinse is 151F/66C. Sanitize option final rinse is 162F/72C. I always have the Extra Dry optied so these final rinse temps are slightly increased.
 
spray power

How much spray power does this Whirlpool dishwasher have? I don't like dishwashers that have wet magnetic rotor pumps that just pee on your dishes. They should just be blasted clean or at least soaked with water like a typhoon or hurricane. Call me old school, but I want to hear a reall pump humming and blasting away with water flying everywhere with a strong charge of water.
 
Cool to hear your review of the WDT970SAKZ. Haven't heard of anyone else here getting one of them, I debated one a couple years ago when I was in the market. The third rack seems really practical for the small Tupperware and serving ware I often use.

Similarly, I've been impressed with the fit and finish of the current WP dishwashers. We have a WDT750SAKZ at a friends pending install while we remodel the rest of the house, and for the $480 he paid it's a really nice machine. The door hinges in particular are surprisingly nice, and the magnetic latch that pulls it shut is one of the best modern latches I've felt on a new dishwasher. Those are such small details that I wouldn't have expected anyone to think about on a machine in that price range, especially when just about all other brands at higher prices are still using older or worse designs. Racks seem appropriately sturdy and it's extremely spacious inside.

The only downside of the 750 and 970 being the pumps, they're rather small and seems like they have a not insignificant failure rate. On the flipside they're very affordable to buy and easy to replace yourself.
 
small pumps

This is one of the reasons why I'm not a fan of these small, puny pumps. I've heard a church friend's dishwasher running and to my dismay, the pump barely sounded like it was doing anything. It sounded like a lawn sprinkler. Sorry, but I've had dishwashers that would just blast the dishes clean. Besides, I have to question how well these pumps can handle tough loads unlike large pumps that just wipe off the crusty crud and send them down the drain. Besides, I don't believe these motors have a cooling fan to keep them from overheating. As for the water charge, I expect the dishwasher to blast the top roof of the cabinet inside just from the bottom arm alone.[this post was last edited: 4/21/2025-22:24]
 
Sound level

I wanted to add that the machine is whisper quiet when running, I can hardly tell it is on. However, there is a point in the cycle where there is a noticeable click sound, and I suspect that it is the top tube sprayer that is rotating back and forth noisily. This isn't bothersome during the day, but at night when an ultra-long cycle is finishing at two in the morning, I can hear it across the house. I don't know why I hear it sometimes and not others. I'll have to pay more attention.
 
A loud click? Wouldn’t that be the detergent door opening?

The top sprayer spins, so there is no side to side motion. It shouldn’t make a noise like that.
 
author's review

The author's review doesn't state what kind of pump it has, therefore I assume that this dishwasher in question has a tiny pond pump that can barely move any water. It's unlike a Maytag with a real pump. That new Whirlpool would sound like a toy. Honestly, I wish I could bring back the power clean and point voyager but with better cleaning power than before. At least they had old school, American grade not playing any games types of pumps. They just got the job done in a reasonable amount of time.
 
 
The loud click may be the detergent dispenser opening, as MichaelZ08 advises, if it occurs once during the cycle (main wash period).  Something else is the source if it occurs repeatedly.

The rinse aid dispenser could conceivably make a repeating click sound when it dispenses, depending on the design of it.  Rinse aid dispensers with adjustable dosage via an options adjustment on electronic controls may dispense a very small amount repeatedly to attain the (variable) target amount.

My dishwasher makes a faint beeping sound when rinse aid dispenses  I counted once but don't recall exactly.  May be five "squirts" per dosage levels 1 to 5 (5, 10, 15, 20, or 25 beeps).
 
The sound

The sound I was referring to is a rhythmic sound more like something turning and hitting something, or something going back and forth, just not smoothly. I suspect it is the top tube that washes the top rack, it is going back and forth. I need to listen again and see if there is a time that it happens. What I can add is that the dishwasher is pretty quiet otherwise, but this particular sound is enough to grab my attention and is just a little irritating. Maybe I can put it into a tech cycle and let it tell me exactly what it is doing when I hear it.
 
Aside from the third rack wash tubes, which are stationary, that 750 I mentioned has an identical wash system. When I did the initial hookup and test post purchase, using the service cycle I never heard a sound like you’re describing. I would be very curious to have you run that and see what’s going on.
