Whirlpool's new dishwasher motors

[pstehle]

No, I don't. I've used these dishwashers before. A real motor and pump would've blasted the dishes clean like it had taken paint off of a Ford building. You need pressure to clean dishes.

Problem is, the EPA and DOE don't want us using any water, power or phosphates, so the detergent has to do all the real work. For the most part, it seems to, though I never had a doubt when my old KDSS19 was doing it's thing! This newer one is post Whirlpool. It needed a wash pump at about 4 years old, but has otherwise done it's job well enough... still hate Whirlpool though. Went from tied for best overall appliance brand 20-odd years ago, to what they're pooping out today...

I wish these new dishwashers still have 3450 rpm motors in them.

At this point my replies are more for those browsing to this site, looking for good data, since Jerome is impervious to evidence.

This is the "Dual Power Filtration" motor and pump assembly for Whirlpool products.
The motor label reads:
.175 Horsepower.
3,380 RPM.
Circulation Pump W10902589

If I had a buck for every one I only had to spin the fan to break loose the seal on ones people let sit for a few months...

Shaded pole motors are not suitable for everything.
Better to go with a beefy motor with a start-run system with a capacitor.

Let's not solely blame the EPA, a popular boogeyman for so many here.
Market forces, yummy free market capitalism also drove manufacturers to put smaller quieter motors in their machines.
Don't forget! Many many familes were purchasing large, open concept homes in the late 90s and 2000s, and the market demanded that dishwashers be as quiet as possible.
Bosch was already the leader back then and everyone chased.
So brands found various solutions in different small motors, and alternating wash arms for less splash noise.
Even today, the market demands that dishwashers be as silent as possible.

I can guarantee you Whirlpool's own models don't use the dual power motor. I'd take the Maytag. It's too bad they alternate wash zones. What people fail to realize is that it takes 2 hours plus on average to do a normal cycle.

Correct, the Whirlpool brand models don't use the Power Filter module. They use a passive filter cup and wet rotor motor.
Taking two hours doesn't matter when 95% of the population does their dishes at night, and runs the cycle overnight.
It especially doesn't matter when dishwashers are so big these days, you can hold multiple days worth of dishes in them.
And on the very rare circumstances you need dishes faster, like on holidays, all these models have 1 Hour wash cycles.
This is a non-issue.

That would be from the low starting torque of a shaded pole motor. GE did good and latter went to the PSC motor with a higher starting torque.

Whirlpool got it right right from the start (pun intended) and used a relay coil with separate start winding.

Me personally, I like a generous starting torque PSC motor that is also over sized for the application.

I know of plenty of people that don't like the long cycles. I am one of them. The one hour wash just skips the thermal holds and leads to very subpar results, worse than what the machine already is capable of doing.
